If 15 people are coming for Thanksgiving, you don’t need 15 side dishes. You need a few big pans of food that people will actually eat.

Potatoes, carrots, canned green beans, and boxed stuffing are good places to start. They’re also much easier on your grocery bill than a recipe that asks for three kinds of cheese and a tiny jar of something you’ll never use again. These 27 cheap Thanksgiving side dishes are built around familiar groceries, with quantities that make sense for a big table.
Pick five or six dishes from the list, not all 27. And choose at least one that doesn’t need the oven. Your turkey already has plans for that space.
Figure out how much food you really need
For a meal with turkey and five sides, a practical starting point is about half a cup of each side per person. Ten guests means roughly five cups of each dish. Make extra of favorites such as mashed potatoes; nobody wants to ration those.
The serving counts below are estimates for side portions, not enormous individual bowls. A pan that serves 10 alongside turkey and several other dishes may serve only six if it’s the only substantial food at a vegetarian potluck.
A quick price check matters too. Compare local prices for potatoes, store-brand green beans, and corn muffin mix, then add the butter, milk, eggs, seasonings and toppings your chosen dishes require. Prices vary by store and date, so check the full shopping total before counting on an exact per-serving cost.

Cheap Thanksgiving side dishes made with potatoes
1. Classic mashed potatoes
A five-pound bag of russets is the easiest way to fill a big serving bowl without spending much. Cut the potatoes into similar-size pieces and simmer until a fork goes through without resistance. Drain, then mash with warm milk, butter, salt, and pepper.
Allow about 30 to 40 minutes and plan on 10 to 12 side servings. A potato masher beats a blender here. A blender can turn the whole pot gluey, which is a rough way to end Thanksgiving morning.
2. Crispy roasted potato wedges
Use four to five pounds of potatoes, scrub the skins, and cut them into wedges. Toss with a little oil, salt, and paprika if you own it. Spread them on two sheet pans and roast around 425°F until browned and tender, turning once. Start checking after 30 minutes.
This serves about 10. But don’t stack all the wedges in one deep pan. They’ll steam instead of crisp, and you’ll end up with something closer to damp baked potatoes.
3. Simple scalloped potatoes
Thinly slice about three pounds of potatoes and layer them in a greased 9-by-13-inch dish. Make a sauce from butter, flour, milk, salt, and pepper, then pour it over the slices. Cover and bake around 350°F until the potatoes are tender, uncovering near the end for a little color.
Plan on 8 to 10 servings and roughly an hour or more in the oven, depending on slice thickness. Skip the cheddar if it’s expensive. Traditional scalloped potatoes can be creamy without turning into a cheese bill.
4. Baked sweet potatoes with cinnamon butter
Buy five medium to large sweet potatoes, scrub them, cut them in half lengthwise, and roast cut-side down around 400°F until soft. That usually takes 35 to 50 minutes, depending on their size.
Ten halves make ten side portions. Serve with a little butter and cinnamon, and let people add brown sugar if they want it. This is the sweet potato dish I’d choose when the grocery budget is tight. No marshmallows, pecans, or special casserole topping needed.

5. Mashed sweet potatoes
For a softer side, boil or roast about four pounds of sweet potatoes until tender, then mash with butter, a little milk, and salt. Add cinnamon if your family likes sweeter flavors.
You’ll get roughly 8 to 10 servings. This can be made the day before and reheated in a covered dish with a splash of milk. I wouldn’t add maple syrup unless there’s already a bottle in the pantry. Buying one for two tablespoons is bad grocery math.
6. Sweet potato casserole with an oat topping
Cook and mash four pounds of sweet potatoes. Spread them in a 9-by-13-inch baking dish and scatter a simple topping of oats, brown sugar, a little flour, and butter over the top. Bake at 350°F until hot and the topping is lightly browned.
It serves about 10 to 12 as part of a larger meal. Check the center with a food thermometer if you’re reheating a prepared casserole; leftovers should reach 165°F. Chopped pecans taste good here, but they’re an easy ingredient to leave out when money is tight.
Vegetables that don’t need a pile of extras
7. Buttered green beans
Three cans of green beans, drained, give you a decent bowl for about 8 to 10 small servings. Four cans are safer if green beans are a family favorite. Heat them on the stovetop with butter, black pepper, and a pinch of salt.
That’s it.
Frozen beans work as well. Look at the price per ounce rather than assuming the frozen bag is cheaper than the can. And save the cream soup and fried onions for a day when you actually want casserole.

8. Green bean casserole
For a classic 9-by-13-inch pan, start with four drained cans of green beans, two cans of condensed cream of mushroom soup, a splash of milk, and fried onions for the topping. Mix the beans, soup, and milk; bake according to the soup manufacturer’s instructions, adding the crispy onions near the end.
Allow 10 to 12 side servings. The cream soup and fried onions add to the bill, so compare the complete ingredient list with plain buttered beans before deciding which version fits your budget.
9. Brown sugar glazed carrots
Peel and slice three pounds of whole carrots. Simmer until nearly tender, drain, and finish in a wide pan with butter and a spoonful or two of brown sugar. A pinch of salt stops the glaze from tasting like candy.
This makes about 10 side portions and takes around 25 minutes. Whole carrots are often worth the few extra minutes of peeling because bagged baby carrots can cost more per pound.
10. Roasted carrots and onions
Use three pounds of carrots and two medium onions. Cut the carrots into thick sticks, slice the onions, toss everything with oil, and roast on a large sheet pan around 425°F until browned at the edges and tender, about 25 to 35 minutes.
That feeds 8 to 10. It’s a different dish from glazed carrots, with savory, caramelized edges rather than sweetness. Add dried thyme if you already have it. Don’t buy a fresh herb packet just for one sheet pan.

11. Garlicky broccoli from the freezer
Buy three 12-ounce bags of frozen broccoli florets for roughly 8 to 10 portions. Roast according to the package or cook on the stovetop until tender, then toss with oil, garlic, and salt.
Frozen broccoli can turn watery if you crowd the pan. Let steam escape and give it enough room to brown. If you’ve already spent money on garlic for the potatoes or stuffing, this dish barely needs anything else.
12. Buttered corn with black pepper
Four regular 15-ounce cans of corn, drained, make an easy side for about 10 guests. Warm the kernels in a saucepan with butter and black pepper. You can also use frozen corn, but check the weight on the bags before deciding how many to buy.
Corn is the side to hand to a willing helper who can’t cook. Five minutes at the stove, one spoon, no elaborate directions. There’s no need to make every dish a major production.

13. Corn pudding
Mix two cans of drained corn, one can of cream-style corn, two boxes of corn muffin mix, eggs, and milk or sour cream according to a reliable corn-pudding recipe. Pour into a greased 9-by-13-inch dish and bake until the middle is set and a thermometer reads 165°F.
A full pan offers about 10 to 12 small servings. The ingredient list matters: if you have to buy a large tub of sour cream and a carton of eggs solely for this recipe, plain buttered corn may be the cheaper choice.
14. Slow-cooked cabbage and onions
Slice a large green cabbage and two onions. Cook the onions in a big pot with a little oil, add the cabbage, season with salt and pepper, then cover and cook on medium-low heat until the leaves soften. Stir occasionally so the bottom doesn’t scorch.
One large cabbage gives roughly 8 to 10 modest servings once cooked down. It’s inexpensive, tastes good with turkey gravy, and doesn’t require the oven. I like this one for a crowded kitchen.
15. Peas with sautéed onions
Heat a chopped onion in butter until soft, then add three 12-ounce bags of frozen peas and cook according to the package until hot. Season with black pepper and keep the heat gentle. Overcooked peas lose their bright color and become mushy.
Plan on 8 to 10 servings. This is especially handy if the rest of your menu is beige. Mashed potatoes and stuffing are lovely, but a little green on the plate won’t hurt.

16. Roasted mixed vegetables from the freezer
Use three bags of plain frozen mixed vegetables, such as carrots, green beans, peas, and corn. Toss with oil, salt, and pepper, then roast at about 425°F on two pans until heated through with a few browned edges.
That gives about 8 side servings, depending on bag size. Frozen vegetables release water, so a single crowded casserole dish won’t roast them well. Buy plain vegetables rather than pre-seasoned blends. You’re paying extra for somebody else to add salt.
Stuffing, bread and filling sides worth the space
17. Classic boxed stuffing
Three 6-ounce boxes of store-brand stuffing mix usually make a generous bowl for around 10 to 12 small side servings, but check the yield on your packages. Follow the directions for water and butter, then fluff with a fork.
It’s one of the most practical Thanksgiving shortcuts. The seasoning’s already handled, and it uses the stovetop instead of a precious oven rack. If you’re feeding a family that prefers homemade, move to the next idea.

18. Onion-and-celery bread stuffing
Cube a large loaf of day-old bread and let the pieces dry. Soften two onions and several celery stalks in butter, toss with bread, broth, and seasoning, then bake in a shallow dish at about 350°F until the top is crisp and the center is safely cooked.
You’ll get about 10 portions, depending on loaf size. If your version contains eggs or poultry broth, follow a tested recipe and heat stuffing to 165°F. Stale bread is useful here, but moldy bread belongs in the trash.
19. Skillet cornbread
Two boxes of basic corn muffin mix, prepared according to the packages, can make a useful pan of cornbread for 10 to 12 guests. Use a greased oven-safe skillet or ordinary baking pan, and bake until the center is fully set.
Check the current local price of an 8.5-ounce box of Jiffy mix, and count the eggs and milk the package calls for in your grocery total. Cut the bread into small squares, because people will already have plenty on their plates.
20. Drop biscuits without rolling dough
For about 12 biscuits, combine roughly three cups of flour with baking powder, salt, and cold butter, then stir in enough milk or buttermilk to form a thick dough. Scoop onto a baking sheet and bake according to a tested biscuit recipe, usually around 425°F until golden.
You don’t need a rolling pin or a biscuit cutter. And if you don’t own baking powder, buying a can only for these biscuits might erase the savings. Store-brand rolls are perfectly fine.

21. Warm store-brand dinner rolls
A 12-count package gives you one roll per guest at a table of 12. For 18 people, buy two packs rather than expecting everyone to politely split one.
Follow the heating directions on the bag, and don’t waste oven time trying to improve a perfectly good roll with a complicated glaze. If you have butter, put a small dish of it on the table. That’s enough.
22. Stovetop macaroni and cheese
Cook one pound of elbow macaroni. Drain and return it to the pot with a little butter, milk, and eight ounces of shredded cheddar. Stir over low heat until the cheese melts, adding milk slowly to keep the sauce loose.
This makes roughly 8 to 10 side servings. You can use half as much cheese for a lighter version, but don’t call it a rich, creamy mac if the noodles barely have any sauce. A store-brand block of cheddar is usually worth comparing against pre-shredded cheese by ounce.
23. Garlic rice pilaf
Rinse three cups of dry long-grain rice if the package recommends it. Cook with sautéed onion, water or broth, and garlic according to the rice package directions, then fluff and let it rest.
That produces enough rice for around 12 side servings. Plain white rice is cheaper than wild-rice blends, and you can use a bouillon cube instead of buying cartons of broth. This is the least traditional item in the group, but it works especially well when turkey gravy is plentiful.

The cold and sweet sides that make the plate feel complete
24. Crunchy cabbage slaw
Shred a small head of green cabbage and a few carrots. Dress with a little mayonnaise thinned with vinegar, a pinch of sugar, and salt. Keep the bowl chilled until serving.
It makes about 10 side portions. Compared with the cooked cabbage dish, this one gives the table something cold and crisp. For a mayonnaise-free version, use oil and vinegar. Most regular mayonnaise contains eggs, so check the label and use an egg-free dressing if needed. Check your guests’ dietary needs before assuming the swap works for everyone.
25. Cranberry-orange sauce
Simmer a 12-ounce bag of fresh cranberries with about a cup of sugar, some water, and the zest or juice of one orange until the berries pop and the sauce thickens. Cool and refrigerate.
That makes about 2 cups, enough for roughly 10 to 12 servings of two to three tablespoons each. Cranberries are tart, so taste before cutting back the sugar too far. This is a great make-ahead job because the sauce actually needs time to cool.
26. Warm cinnamon apples
Peel and slice about three pounds of apples, then gently cook them in a wide pan with a little butter, cinnamon, and brown sugar until tender but not falling apart. Depending on thickness, allow about 15 to 25 minutes.
You’ll get 8 to 10 small portions. Choose apples that hold their shape, such as Granny Smith or Honeycrisp when priced reasonably. This isn’t pie filling pretending to be a vegetable. It’s a sweet side, and I’d serve small spoonfuls.
27. Deviled eggs
Hard-cook a dozen eggs using a tested method, cool them promptly, peel, and cut in half. Mash the yolks with mayonnaise, a little mustard, and salt, then spoon the filling back into the whites.
Twenty-four halves feed 12 people at two halves each. Eggs can jump in price, so compare the dozen price before committing. Keep the tray refrigerated and set it out shortly before everyone eats. Warm deviled eggs sitting on a counter for an afternoon are nobody’s Thanksgiving tradition.

Spend less by letting ingredients do double duty
Before shopping, write the five or six sides you’ve chosen on paper. Circle every ingredient that appears twice. Butter works in mashed potatoes, carrots, and stuffing. Milk covers potatoes, mac and cheese, and some corn mixes. Onions can go into bread stuffing, cabbage, and peas.
Buying separate specialty ingredients for every dish is how a supposedly cheap meal turns into a $90 pile of sides.
If I were feeding 12 to 15 people and wanted to keep the menu simple, I’d choose mashed potatoes, boxed stuffing, buttered green beans, glazed carrots, stovetop macaroni, and cranberry sauce. That gives you several different textures without asking your oven to do six things at once.
For a larger party, scale the crowd favorites first. Doubling mashed potatoes is sensible. Doubling every single side means a refrigerator full of food nobody asked for.
A one-oven Thanksgiving plan that doesn’t fall apart
Two days ahead, make the cranberry sauce and prepare the shopping checklist. If you’re making homemade stuffing, dry the bread cubes. Wash the vegetables and keep cut produce refrigerated.
The day before, assemble casseroles without their crunchy toppings and refrigerate promptly. Prepare the slaw dressing separately so the cabbage doesn’t go limp. Peel and cut potatoes if you like, but keep them submerged in cold water in the refrigerator, not on the counter.
On Thanksgiving morning, get the turkey going first. Cook green beans, cabbage, rice, and macaroni on the stove. Roast potatoes or casseroles after the turkey comes out, provided your planned oven time allows it. Use two shallow dishes instead of one deep overfilled casserole when scaling up; the center will heat more evenly.
For safety, USDA guidance says to keep hot perishable foods at 140°F or above and cold foods at 40°F or below. Refrigerate perishable food within two hours if it isn’t being kept at a safe temperature, or within one hour if the surrounding temperature is above 90°F. Reheat leftovers to 165°F. Casseroles and stuffing also need to reach a safe 165°F.
Three questions to answer before buying anything
Which Thanksgiving sides are cheapest for a really big group?
Start with mashed potatoes, simple rice pilaf, cooked cabbage, carrots, and boxed stuffing. Each can be made in a large pot or pan with basic groceries. A cheesy casserole may still be worth serving, but it often costs more once you count all the dairy and toppings.
How many sides do I need for 20 people?
I’d start with five or six substantial sides plus the turkey and dessert. Make around 10 cups of each side if guests are taking half-cup portions, and increase the dishes you know everyone likes. For vegetarian guests, include at least one filling main option rather than expecting vegetables and rolls to do all the work.
What’s best to make the day before?
Cranberry sauce, chilled slaw components, and assembled casseroles are sensible choices. Keep them refrigerated, store crunchy toppings separately, and follow safe reheating directions. Mashed potatoes can be made early too, but fresh potatoes usually taste better and avoid another reheating job.
Pick your six, then count the pans
Write down your menu and place the actual pots and baking dishes on the counter. If two recipes need the same 9-by-13-inch pan at the same time, change one dish now. It’s cheaper to switch to buttered green beans than to buy another roasting pan the night before Thanksgiving.
