19 Easy Thanksgiving Side Dishes That Practically Make Themselves
19 Easy Thanksgiving Side Dishes That Practically Make Themselves
The turkey gets the attention, but the side dishes are what fill the plate — and they are usually what make Thanksgiving day feel hectic. These easy Thanksgiving side dishes are chosen with one goal in mind: most of the work happens ahead of time, in a slow oven, or in a dish that assembles in minutes and bakes while you do something else. Every idea below includes when to make it, what temperature it needs, and how it fits alongside everything else competing for oven space.
You do not need all 19. Pick two potatoes or one, two vegetables, a bread, a sauce, and one fresh salad, and you have a complete, balanced Thanksgiving dinner menu for a crowd.
How to Use This List
Each side is labelled by timing so you can build a plan that suits your kitchen:
- Make 2 days ahead: flavours improve in the fridge; reheat or serve cold.
- Make 1 day ahead: assemble, cover, refrigerate, and bake on the day.
- Day-of, hands-off: minimal chopping, then the oven or stovetop does the work.
Most casseroles here bake happily at 350°F (175°C), which is deliberate — dishes that share a temperature can share the oven. Where a side needs a different temperature, the entry says so and suggests when to cook it instead.
1. Make-Ahead Mashed Potato Casserole
All the comfort of mashed potatoes without mashing them while the turkey rests. Russet or Yukon Gold potatoes are boiled, mashed with butter, cream cheese, and a splash of warm milk, then spread into a buttered casserole dish, dotted with butter, and covered.
Make-ahead: Assemble 1–2 days ahead and refrigerate. On the day: Bake covered at 350°F (175°C) for about 30 minutes, then uncovered for 10–15 minutes until the top is lightly golden and the centre is steaming. Serves 10–12 as a side. Practical tip: Add an extra splash of milk before baking, because chilled potatoes absorb liquid as they sit.
2. Sweet Potato Casserole with Crunchy Pecan Topping
Mashed sweet potatoes with butter, a little brown sugar, cinnamon, and vanilla, topped with a rubble of chopped pecans, flour, and brown sugar that bakes into a crisp lid. The contrast — silky underneath, crunchy on top — is what makes this version memorable.
Make-ahead: The filling keeps 2 days ahead; add the topping just before baking so it stays crisp. On the day: Bake at 350°F (175°C) for 30–35 minutes. Serves 10–12. Practical tip: Roasting the sweet potatoes instead of boiling them concentrates their flavour and keeps the filling from turning watery. A spoonful of apple butter whisked into the filling adds gentle apple spice without extra sugar.
3. Creamy Scalloped Potatoes
Thinly sliced potatoes layered with garlic-infused cream and a scattering of Gruyère or sharp cheddar, baked low and slow until the slices are tender and the top is bronzed. There is no roux and no fuss — the starch from the potatoes thickens the cream as it bakes.
Make-ahead: Assemble 1 day ahead; press cling film directly onto the surface to prevent discolouration. On the day: Bake at 350°F (175°C) for 60–75 minutes and rest 10 minutes before serving so the sauce sets. Serves 8–10. Practical tip: A mandoline or the slicing disc of a food processor gives even slices, which means even cooking — thick and thin pieces in the same dish finish at different times.
4. Roasted Garlic Mashed Potatoes
The day-of alternative to the casserole in item 1. A whole head of garlic is roasted until soft and sweet, then squeezed into hot mashed potatoes with butter and warm cream. Roasted garlic is mellow rather than sharp, so the potatoes stay family-friendly while tasting noticeably deeper.
Timing: Roast the garlic 2 days ahead and refrigerate the squeezed cloves; mash the potatoes on the day in about 30 minutes. Serves 8–10. Keep-warm tip: Mashed potatoes hold well for up to 2 hours in a slow cooker on the Warm setting, stirred once or twice — a lifesaver when the stovetop is full.
5. Twice-Baked Potato Casserole
Everything inside a loaded baked potato — cheddar, spring onions, a little sour cream, and crumbled cooked bacon if you like — folded through chunky mashed potatoes and baked until bubbling. It eats like comfort food but serves like a scoopable side, which is far easier for a crowd than splitting individual potatoes.
Make-ahead: Assemble 1 day ahead without the final cheese layer; add the cheese before baking. On the day: Bake at 350°F (175°C) for 30–40 minutes. Serves 10. Practical tip: Leave the mash slightly chunky; an over-smooth base turns gluey once it is baked a second time.
6. Green Bean Casserole, Lightened Up
The classic, made fresher: green beans are blanched until just tender, folded into a simple mushroom cream sauce made on the stovetop, and topped with crispy fried shallots or onions. Making the sauce yourself takes about 10 extra minutes and avoids the gummy texture canned soup can give.
Make-ahead: Blanch the beans and make the sauce 1 day ahead; combine and top on the day. On the day: Bake at 350°F (175°C) for 20–25 minutes until bubbling. Serves 8–10. Practical tip: Salt the blanching water well and chill the beans in cold water — that is what keeps them bright green after baking.
7. Honey-Glazed Carrots
Carrots simmered until tender, then glazed in a pan with butter, honey, and a pinch of salt until shiny. They cook on the stovetop, need no oven space at all, and their sweetness balances the rich, savoury dishes around them.
Timing: Day-of, about 25 minutes start to finish; the peeled, cut carrots can wait in water in the fridge from the day before. Serves 8. Practical tip: Cut carrots on a diagonal into similar-sized pieces so they finish together, and let the glaze reduce until it coats the back of a spoon — a watery glaze slides straight off.
8. Butternut Squash Mac and Cheese
A cheese sauce blended with roasted butternut squash, which gives the mac a golden colour and a subtle sweetness while letting you use a little less cheese without anyone feeling short-changed. Sharp cheddar and a pinch of mustard keep the flavour recognisably mac and cheese.
Make-ahead: Roast the squash and blend the sauce 2 days ahead; cook pasta and assemble on the day, or assemble fully 1 day ahead and add a splash of milk before baking. On the day: Bake at 350°F (175°C) for 25–30 minutes. Serves 10–12. Practical tip: Cook the pasta 1–2 minutes shy of the packet time — it finishes in the sauce and will not turn soft.
9. Corn Casserole
Part spoon bread, part pudding: corn kernels, creamed corn, a simple cornmeal batter, butter, and a little sour cream, stirred together in one bowl and baked until just set with golden edges. It is one of the easiest thanksgiving casseroles on this list — no separate steps, no whisking egg whites.
Make-ahead: Mix the batter up to 1 day ahead; bake fresh on the day for the best rise. On the day: Bake at 350°F (175°C) for 45–55 minutes. Serves 8–10. Practical tip: The centre should jiggle very slightly when you nudge the dish; it firms up as it rests for 10 minutes.
10. Roasted Brussels Sprouts with Cranberry and Orange
Halved sprouts roasted at high heat until the edges char, then tossed with dried cranberries and orange zest. The bitterness of the sprouts, the tart fruit, and the citrus make this the side that cuts through a rich plate.
Timing: Day-of and fast. Roast at 425°F (220°C) for 20–25 minutes — do this while the turkey rests, when the oven is free to run hot. Serves 8. Practical tip: Give the sprouts space on the tray, cut-side down. Crowded sprouts steam and go grey; spaced sprouts caramelise.
11. Cornbread Casserole Dressing
Crumbled cornbread combined with sautéed onion, celery, sage, and stock, baked in a dish rather than inside the bird — which means a crisp top, even cooking, and far easier timing. Baking dressing separately is also the food-safe approach, because it can reach a safe, steaming-hot temperature throughout without overcooking the turkey.
Make-ahead: Bake the cornbread 2 days ahead (stale cornbread absorbs stock better) and assemble the dressing 1 day ahead. On the day: Bake at 350°F (175°C) for 35–45 minutes. Serves 10–12. Practical tip: Add stock gradually — you want the mixture moist like thick porridge, not soupy, because it releases more liquid as it bakes.
12. Classic Herb Stuffing with Apples
Cubed bread, butter, onion, celery, sage, thyme, and diced apple for small bursts of sweetness. Where item 11 is cornbread-based and Southern in style, this is the bakery-bread version many families expect, and apple makes it a natural partner for anything spread or glazed with apple butter.
Make-ahead: Dry the bread cubes 1–2 days ahead (or overnight spread on trays); sauté the vegetables 1 day ahead. Assemble and bake on the day for the best texture contrast — crisp top, soft middle. On the day: Bake at 350°F (175°C) for 30–40 minutes. Serves 10. Practical tip: Warm stock hydrates the bread more evenly than cold, so heat it before pouring it over.
13. Soft Homemade Dinner Rolls
Pillowy yeast rolls are the one side guests reliably reach for twice, and they are more make-ahead friendly than they seem. The dough can be shaped into balls the day before, refrigerated overnight, then proofed and baked on the day, so the house smells of fresh bread without a morning of kneading.
Make-ahead: Shape 1 day ahead and chill; or bake fully 1 day ahead and rewarm, wrapped in foil, at 300°F (150°C) for 10 minutes. Makes about 12–15 rolls. Serving tip: Warm rolls are the perfect vehicle for a spread of smooth apple butter — set out a small dish alongside the butter dish for a simple, seasonal extra that takes no cooking at all.
14. Homemade Cranberry Sauce
Fresh or frozen cranberries simmered with sugar and orange juice for about 10 minutes, until the berries pop and the sauce thickens as it cools. It tastes bright and genuinely fruity in a way that makes the canned version hard to go back to — and it is the single easiest make-ahead item on this entire list.
Make-ahead: Make it up to a week ahead; the flavour improves after a day or two in the fridge. Serves 10–12 in sauce portions. Practical tip: Pull it off the heat while it still looks slightly loose. Cranberry sauce sets firmly as it chills, and an over-reduced batch can turn jelly-stiff.
15. Simple Turkey Gravy
Good gravy needs only pan drippings, flour, and stock: cook the flour in the fat until it smells nutty, then whisk in warm stock a little at a time and simmer until it coats a spoon. Making a practice batch from a tub of stock and butter a few days early is a low-stakes way to learn the consistency if gravy is new to you.
Timing: Day-of, about 15 minutes, made while the turkey rests. Practical tip: Whisk constantly as the first stock goes in and add it gradually — lumps form when cold liquid floods hot roux all at once. Strain at the end for insurance, season last, and keep it warm, not boiling, so it does not skin over.
16. Apple, Walnut and Celery Salad
A crisp, crunchy salad of sliced apples, toasted walnuts, celery, and a light lemon and honey dressing. It is served cold, needs no cooking on the day, and its freshness is exactly what a plate of casseroles needs next to it.
Make-ahead: Toast the nuts and mix the dressing 2 days ahead; slice the apples and toss everything together within an hour of serving. Serves 8–10. Practical tip: Toss the apple slices in the lemony dressing straight after cutting — the acid slows browning far better than water does.
17. Cranberry Fluff Salad
A sweet-tart, make-ahead favourite: ground or finely chopped cranberries are sweetened and rested so their sharpness softens, then folded with whipped cream (or whipped topping), crushed pineapple, and mini marshmallows. It sits somewhere between salad and dessert, and many families would notice its absence.
Make-ahead: Must be made 1 day ahead so the cranberries mellow and the marshmallows soften — a planning feature, not a chore. Serves 10–12. Practical tip: Drain the pineapple thoroughly; excess juice is the main reason this salad turns soupy overnight.
18. Green Salad with Glazed Pecans and Maple Vinaigrette
Sturdy greens, quick-candied pecans, shaved red onion, and a maple and cider vinegar dressing. It takes 10 minutes, most of it making the pecans, and those pecans can be cooked a week ahead and kept in a jar.
Make-ahead: Pecans up to a week ahead; dressing 3–4 days ahead. Dress the leaves at the table, never before. Serves 8–10. Practical tip: Use robust leaves such as little gem, endive, or baby kale — delicate salad leaves wilt under a warm, heavy Thanksgiving plate if they sit dressed.
19. Marinated Vegetable Salad
Blanched green beans, red onion, cherry tomatoes, and sweet peppers in a tangy vinegar and herb marinade. Unlike every casserole above, this side actually improves over 2 days in the fridge, it is served at room temperature, and it frees you completely from the oven schedule.
Make-ahead: Make 1–2 days ahead; pull it out of the fridge an hour before serving so the flavours wake up. Serves 8–10. Practical tip: Marinate the onions first for 15 minutes — it takes their raw bite down before they meet the other vegetables.
A Simple Thanksgiving Cooking Timeline
- 2 days before: Make the cranberry sauce (item 14) and cranberry fluff (item 17, next day finish), bake cornbread for the dressing, roast garlic, toast nuts, mix salad dressings.
- 1 day before: Assemble the potato, sweet potato, and stuffing dishes; blanch beans and make the mushroom sauce; shape the rolls; marinate the vegetable salad.
- Morning of: Take casseroles out of the fridge 30–45 minutes before baking so they cook evenly.
- While the turkey roasts: Bake the 350°F casseroles in rotation, keeping finished dishes warm and covered.
- While the turkey rests (30–45 minutes): Turn the oven up for the Brussels sprouts, bake or rewarm the rolls, simmer the glazed carrots, and make the gravy.
- Just before serving: Dress the salads, slice the rolls, and strain the hot gravy into a warm jug.
Conclusion
Easy Thanksgiving side dishes are not about shortcuts that taste like shortcuts — they are about choosing recipes whose hard work happens on Tuesday and Wednesday instead of all at once on Thursday. Start with one make-ahead potato casserole, one vegetable, the cranberry sauce, and a batch of rolls, and add from there only if you want to.

Frequently Asked Questions
How many side dishes do I need for 10–12 guests?
Five to seven sides is a comfortable range for 10–12 guests: two potato or starch dishes, two vegetables, one bread, cranberry sauce and gravy, plus one fresh salad if you like. Plan roughly 350–450g (about 3–4 cups) of total side dishes per person rather than a full portion of every dish — guests take a little of everything.
Which Thanksgiving sides can be made 2 days ahead?
Cranberry sauce keeps happily for a week. Beyond that, the safest 2-day tasks are the components: sweet potato filling (without its topping), roasted garlic, salad dressings, candied nuts, toasted breadcrumbs and cornbread for dressing. Fully assembled casseroles are best at 1 day ahead, and fresh salads should be assembled on the day, even when their parts were prepped earlier.
How do I keep sides warm when the oven is full?
Use the tools around the oven: a slow cooker on Warm holds mashed potatoes and gravy well, casseroles stay hot for 30–45 minutes tented with foil on top of the warm stove, and a preheated insulated bag or a cooler lined with towels keeps baked dishes hot during a short wait. Rotate dishes through the oven in order of how well they hold — salads and cranberry sauce need no heat at all, so they never compete for space.
