Every year I make the side dishes, and I also want to fit in a workout before anyone shows up. So I do almost all of it on Tuesday and Wednesday, while the kitchen is still quiet. These are the sides that hold up in the fridge and reheat without tasting like leftovers. That leaves less to do on Thursday.

These sides are sorted by how much of the work happens before Thanksgiving Day.

Cooked fully in advance

    These are cooked ahead and either reheated or served cold or at room temperature.

    Garlic Mashed Potatoes

    I make these 2 days out. Stir a scoop of plain Greek yogurt in with the butter and you get extra protein plus a tang that keeps them from tasting flat after reheating. Warm them covered at 350°F with a splash of milk, stirring once halfway. They come out as creamy as the day you made them.

    Potatoes au Gratin

    Potatoes au gratin

    Layered potatoes, cream, and a lot of cheese. This one improves after a night in the fridge, because the slices soak up the sauce and set. Bake it fully on Wednesday, then reheat at 325°F under foil until it bubbles at the edges. Gruyère and sharp cheddar add some protein too.

    Homemade Creamed Corn

    This is a homemade version of creamed corn. Sweet corn simmered with butter, a little cream, and Parmesan comes together in 15 minutes and keeps in the fridge for 4 days. Reheat it low on the stovetop and loosen it with milk as you go. The kids go back to it for seconds.

      Garlic Mashed Parsnips

      This is an alternative to potatoes. Parsnips mash up sweet and a little peppery, and roasted garlic makes them richer. They reheat exactly like mashed potatoes, so make both batches on the same afternoon. A spoonful of Greek yogurt folded in at the end keeps them light.

      Lemon Parmesan Orzo

      Orzo works well on a make-ahead menu. Toss it warm with lemon, Parmesan, and a handful of herbs, and it holds up in the fridge for 2 days. Fold in white beans or shredded chicken to add protein. Serve it at room temperature so it doesn’t take up oven space.

      Cornbread Squares

      Bake it on Wednesday, cut it into squares, and wrap the whole pan in foil. A 10-minute warm-up in the oven reheats it. I swap some of the milk for Greek yogurt, which gives it a tender crumb and a little more protein. I serve it with honey butter.

      Cheddar Bay Biscuits

      Cheddar bay biscuits

      These freeze well. Bake them up to 2 weeks early, freeze them flat, and reheat at 350°F for 8 minutes. The garlic butter goes on after they’re warm, not before. Sharp cheddar carries the flavor and brings some protein along with it.

      Baked Cinnamon Apples

      This can be a side dish or a dessert. Apples bake down with cinnamon, a little brown sugar, and butter, and they hold for 3 days in the fridge. Reheat them in a covered dish and serve them next to the turkey. Leftovers go on top of Greek yogurt the next morning for a protein breakfast.

      Butternut Squash Soup

      Butternut squash soup

      I like having a pot of this going for the people who show up hungry before dinner. Soup is simple to make ahead, and it tastes better on day 2. Blend in a can of white beans and you add protein and body without changing the flavor. Serve it in mugs so people can sip while they mingle.

      Slow-Baked Beans

      Baked beans

      Beans are a protein source on a holiday table. These bake low and slow with bacon, onion, and a little brown sugar, and they only get better in the fridge. Make them 3 days out and reheat them in a slow cooker so they stay warm all afternoon. This also frees up oven space.

      Roasted Cauliflower and Chickpea Salad

      Chickpeas add protein to this side. Roast them with the cauliflower until crisp, then dress everything with lemon, parsley, and olive oil. It holds for 3 days and is served at room temperature, so there’s no reheating.

      Rosemary Focaccia

      Bake it the day before and warm it for 5 minutes before dinner. Focaccia is forgiving, and a long overnight rise in the fridge gives it more flavor. Top it with flaky salt and fresh rosemary.

        Assembled ahead and baked on the day

        Thanksgiving Stuffing Casserole

        I make the stuffing first. Assemble the whole casserole the day before, cover it tight, and bake it straight from the fridge with 10 extra minutes on the clock. I fold in browned turkey sausage, which adds protein. The top still crisps in the oven.

        Creamy Mac and Cheese

        Blend 1 cup of cottage cheese into the sauce. It adds protein and keeps the sauce silky after reheating, which is where most baked mac goes dry. Undercook the pasta by 2 minutes so it isn’t soft by Thursday. Hold the breadcrumb topping until right before it goes in the oven.

        Texas Roadhouse Rolls

        Texas roadhouse rolls

        I make these sweet rolls from scratch once a year. Shape them the night before, let them rise slowly in the fridge, and bake them fresh on Thursday morning. The cinnamon honey butter keeps for a week, so make that early too.

        Herb Roasted Baby Red Potatoes

        Not everyone wants mash. Par-boil the potatoes on Wednesday, toss them in oil and herbs, and keep them covered in the fridge overnight. On Thursday they need 30 minutes at 425°F to get crisp and golden. Season them with rosemary and garlic.

        Loaded Twice-Baked Potatoes

        Loaded baked potatoes

        Scoop, mash, stuff, and refrigerate. Mix the filling with cheddar, bacon, and Greek yogurt in place of sour cream, which keeps the protein up. They bake straight from the fridge in about 25 minutes at 375°F, and each one is already its own serving.

        Broccoli Cauliflower Bake

        This green casserole doesn’t use canned soup. Toss broccoli and cauliflower with garlic, olive oil, and Parmesan, then load it into the baking dish the night before. It goes into the oven cold and comes out tender. Throw extra cheese on top for the last 5 minutes to get a golden crust.

        Parmesan Spaghetti Squash Boats

        Roast the squash halves on Tuesday, fluff the strands, and stuff them back in with ricotta, Parmesan, and garlic. They sit covered in the fridge until Thursday, then bake at 375°F for 20 minutes. Ricotta carries the protein, and it keeps the squash creamy instead of watery.

        Prepped ahead and cooked on the day

        The vegetables are cut or blanched early, then roasted or pan cooked before dinner.

        Green Beans with Almonds

        Blanch the beans on Tuesday, shock them in ice water, and dry them well before they go in a bag in the fridge. On the day, they need 5 minutes in a hot pan with butter, garlic, and toasted almonds. The almonds add crunch and a little plant protein. It’s the lightest dish on the table.

          Roasted Brussels Sprouts

          Trim and halve the sprouts up to 3 days ahead and store them dry. That’s the only make-ahead step, since the roasting only takes 25 minutes at 425°F while the turkey rests. Finish them with a drizzle of balsamic right out of the oven. Give them room on the pan so the edges crisp.

          Roasted Carrots and Green Beans

          This uses one sheet pan and two vegetables. Cut everything on Tuesday so it’s ready to go, then roast at 425°F while you carve. The carrots caramelize, the green beans blister a little, and a squeeze of lemon at the end brightens it.

          Put together at serving time

          Parts are prepped ahead, and the salad is tossed or plated right before dinner.

          Roasted Butternut Squash Arugula Salad

          A salad balances a heavy table. Roast the squash cubes ahead, keep the arugula and feta separate, and toss everything together right before dinner. Feta and toasted pepitas add protein. A simple maple vinaigrette ties it together.

          Roasted Beet Salad

          Beets work well here because they’re good cold. Roast and slice them up to 4 days out, then build the salad at the last minute with arugula and shaved Parmesan. It’s bright and peppery, which balances the rest of the meal. Add goat cheese if you want it creamier.

          Pear Pomegranate Salad

          This salad looks like more work than it is. Seed the pomegranate and shake up the dressing the day before, then slice the pears right before serving so they don’t brown. Candied walnuts bring crunch and a bit of protein. It’s fresh and balances the heavier dishes.

          Acorn Squash Salad

          Roasted acorn squash over a bed of greens looks more like a centerpiece than a side. Roast the squash on Wednesday and let it come to room temperature before plating. Top it with crumbled goat cheese and toasted pecans. Leftovers make a Friday lunch with sliced turkey on top.

          Spinach Salad with Feta

          Keep one thing on the table raw and crunchy. Spinach, feta, red onion, and a sharp vinaigrette come together in 5 minutes. Slice a few hard-boiled eggs over the top for protein. Boil the eggs and mix the dressing 3 days out, and the rest takes minutes.
