Every November I make the same promise to myself: this year I will not be mashing potatoes at 2 p.m. while the turkey sits there judging me. And every year, I break it. But here is what I have learned after hosting twelve Thanksgivings in a kitchen the size of a postage stamp: the sides are what people actually remember, and the right lineup of sides is what keeps you sane.

So I put together the twenty side dishes my family and friends request over and over, from the green bean casserole that my aunt claims is hers (it is not) to a brown butter mashed potato situation that made my brother-in-law go quiet for a full minute. Some are creamy, some are crispy, several can be made two days ahead, and all of them are designed to share an oven without a fistfight.
You do not have to make all twenty. Pick three or four, add a salad and a roll, and you are done. That is the whole secret, and I am giving it to you for free.
Why You'll Love This Recipe
About the Ingredients
3 lbs (1.4 kg) russet or Yukon Gold potatoes, peeled and cut into 1 1/2-inch chunks
Russets give you a fluffier mash, Yukon Golds give you a creamier one, so pick based on whether you like fluffy or silky. If you are short on time, baby gold potatoes work and you can skip peeling entirely.
1/2 cup (113 g) unsalted butter, plus 2 tablespoons for the topping
European-style butter has more fat and browns more evenly, which is what you want here. Salted butter works too, just cut the added salt in the recipe by half.
1 cup (240 ml) whole milk or half-and-half, warmed
Warm dairy absorbs into potatoes instead of turning them gluey, so microwave it for 45 seconds first. For a lighter version, use 2% milk plus 2 tablespoons of sour cream.
1 1/4 cups (150 g) French fried onions, divided
Buy the classic can or grab a bag of crisp fried shallots at an Asian market for a punchier topping. If you are gluten-free, check the label because many brands sneak in wheat flour.
1 1/2 lbs (680 g) fresh green beans, trimmed and cut in half
Fresh beans stay snappy, but frozen whole beans work in a pinch with no thawing needed. Look for beans that snap cleanly when you bend them, which means they are fresh, not woody.
10.5 oz (297 g) condensed cream of mushroom soup
Yes, the can. It is the flavor everyone expects. If you want to skip it, whisk 1 cup of heavy cream with 1 tablespoon of flour and 4 oz of sauteed mushrooms instead.
1 cup (100 g) shredded sharp cheddar cheese
Sharp cheddar cuts through the creaminess, but Gruyere or a smoked gouda are excellent swaps. Buy a block and shred it yourself, since pre-shredded cheese is coated in starch and melts grainy.
2 lbs (900 g) Brussels sprouts, halved lengthwise
Smaller sprouts (about 1 inch wide) are sweeter and less bitter than the big ones. If yours are large, quarter them so they roast evenly instead of steaming in the middle.
3 tablespoons (45 ml) olive oil, plus more for drizzling
Avocado oil has a higher smoke point and works beautifully at 425F. Do not use extra virgin for high-heat roasting if you dislike a slightly bitter edge.
1 cup (120 g) pecans, roughly chopped
Toast them for 5 minutes in the same oven for a deeper flavor. Walnuts or hazelnuts are fine substitutes, and candied pecans make it feel fancy.
1/4 cup (60 ml) pure maple syrup
Grade A amber is the most versatile. Honey works as a 1-to-1 swap, though it browns a little faster so keep an eye on the broiler.
1 tablespoon (15 ml) balsamic vinegar
Aged balsamic is thicker and sweeter; regular balsamic is sharper but still delicious. If you only have red wine vinegar, use half the amount.
Tips & Tricks
Do Not Overcrowd the Pan
Vegetables that touch steam instead of roast, so use two sheet pans for the Brussels sprouts and give them room, even if it means an extra rack in the oven.
Salt Your Potato Water Like the Sea
Potatoes absorb almost no salt after cooking, so add 1 tablespoon of kosher salt to the boiling water and they will taste seasoned from the inside out.
Warm Your Dairy Before Mashing
Cold milk hits hot potatoes and turns them waxy, so warm it in the microwave for 45 seconds and add it in three pours, mixing between each.
Make the Casserole Ahead, Bake It Later
Assemble the green bean casserole up to 24 hours ahead, refrigerate it covered, then add the fried onions and bake straight from cold, adding 10 minutes to the bake time.
Pro Tips
Step-by-Step Instructions
1. Boil the Potatoes
Cover the potato chunks with cold water by 2 inches, add 1 tablespoon kosher salt, and bring to a boil over high heat. Reduce to a steady simmer and cook 15 to 18 minutes at 200F to 205F (93C to 96C) until a knife slides in with zero resistance and the edges look slightly floury.
2. Brown the Butter
While the potatoes cook, melt 1/2 cup butter in a small saucepan over medium heat and swirl for 4 to 6 minutes until the foam subsides, the milk solids turn nutty golden brown, and it smells like toasted hazelnuts. Pull it off the heat immediately so it does not burn.
3. Mash and Fold
Drain the potatoes and let them steam-dry in the colander for 2 minutes, then rice or mash them. Stir in the warm milk in three additions, then the brown butter, 1 teaspoon salt, and 1/2 teaspoon black pepper until smooth and glossy.
4. Build the Green Bean Casserole
Toss the green beans with the mushroom soup, 1/2 cup milk, 1/2 cup of the fried onions, and 1/2 teaspoon pepper in a 9×13-inch baking dish. Spread it flat so the sauce bubbles evenly rather than pooling in the center.
5. Bake the Casserole
Bake at 350F (175C) for 25 minutes until the edges bubble and the sauce thickens. Scatter the remaining 3/4 cup fried onions and the cheddar on top and bake another 5 to 7 minutes until the onions are deep golden and the cheese is fully melted.
6. Roast the Brussels Sprouts
Toss the halved sprouts with olive oil, 1 teaspoon salt, and 1/2 teaspoon pepper on a sheet pan, cut side down. Roast at 425F (220C) for 22 to 25 minutes until the cut sides are deeply caramelized and a leaf or two is charred at the edges.
7. Glaze and Finish
Drizzle the maple syrup and balsamic over the hot sprouts, add the toasted pecans, and toss gently. Return to the oven for 4 minutes at 425F (220C) so the glaze clings and turns sticky instead of watery.
8. Plate and Hold Warm
Spoon the potatoes into a warm bowl, top the casserole with a final handful of onions, and pile the sprouts on a platter. Cover loosely with foil and hold everything in a 200F (93C) oven for up to 30 minutes before serving.
Delicious Variations
Loaded Baked Potato Mash
Fold in 1 cup sour cream, 1 cup shredded cheddar, and 6 slices of crumbled bacon for a steakhouse-style side that needs no gravy.
Crispy Shallot and Thyme Casserole
Swap the fried onions for crispy fried shallots and add 1 teaspoon fresh thyme to the green bean mixture for a more grown-up flavor.
Bacon-Balsamic Brussels Sprouts
Toss the roasted sprouts with 4 slices of crumbled bacon and a splash of the bacon fat along with the maple glaze for a smoky, sweet-and-salty version.
How to Store 20 Crowd Favorite Thanksgiving Side Dish Recipes
Refrigerator
Store each side in its own airtight container for up to 4 days. Keep the fried onion topping separate so it stays crisp, and store the Brussels sprouts without the pecans so they do not go soft.
Freezer
Mashed potatoes freeze beautifully for up to 2 months in a freezer bag with the air pressed out. The green bean casserole can be frozen unbaked for up to 1 month, but the Brussels sprouts do not freeze well and are best eaten fresh.
Reheating
Reheat potatoes and casserole covered at 350F (175C) for 20 to 25 minutes, stirring 1 tablespoon of milk into the potatoes if they look dry. Re-crisp the Brussels sprouts on a sheet pan at 425F (220C) for 6 to 8 minutes.
Frequently Asked Questions
Q: Can I make these Thanksgiving side dishes ahead of time?
Yes, most of them can be prepped one to two days in advance. Boil and mash the potatoes, assemble the green bean casserole without the topping, and trim the Brussels sprouts, then refrigerate everything separately and bake on the day.
Q: How many side dishes do I need per person for Thanksgiving?
Plan on 3 to 4 side dishes total for a group of 8 to 10 people. That gives everyone a scoop of each without leaving you with a refrigerator full of leftovers for a week.
Q: What temperature do I bake a green bean casserole at?
Bake it at 350F (175C) for 25 minutes, then add the fried onions and cheese and bake 5 to 7 more minutes. The sauce should be bubbling at the edges and the topping should be deep golden brown.
Q: Why are my mashed potatoes gluey instead of fluffy?
You are overworking the starch, usually with a hand mixer or an overzealous masher. Use a ricer or a simple masher, add warm dairy in small additions, and stop the second the potatoes look smooth.
Q: How do I keep roasted Brussels sprouts from getting soggy?
Dry them completely, use a hot 425F (220C) oven, and give them space on the pan so they roast instead of steam. Cut side down is the move, and do not stir them more than once.
Pick three of these sides, write your grocery list tonight, and give yourself the gift of a calm Thanksgiving morning. You do not need twenty dishes to be a hero, you just need a few that work. You're doing better than you think.
