Thanksgiving is one of the most wonderful times of the year, but let’s be honest—it can also be incredibly stressful.
Between prepping the turkey, setting the table, and entertaining guests, the last thing you need is a dozen side dishes demanding your attention all at once.
The good news? Many classic Thanksgiving sides can be made ahead of time, giving you more freedom to enjoy the day with your loved ones instead of being stuck in the kitchen.
1. Classic Sage & Sausage Stuffing
Stuffing is practically the star of the Thanksgiving table, but it doesn’t have to be a last-minute scramble. You can prepare the entire dish up to three days before the big feast and store it covered in the refrigerator.
When Thanksgiving morning arrives, simply pop it in the oven to reheat, and you’ll notice something magical—the flavors actually deepen and meld together beautifully overnight. The sage, sausage, and herbs become even more aromatic and delicious.
This means less stress for you and more time to focus on other dishes or spend quality moments with family. Just be sure to let it come to room temperature for about 30 minutes before reheating to ensure even warming throughout.
2. Mashed Sweet Potatoes
Sweet potatoes bring natural sweetness and vibrant color to your Thanksgiving spread, and the best part? You can roast and mash them up to five days before the holiday. Simply store the mashed sweet potatoes in an airtight container in the fridge.
When it’s time to serve, gently reheat them on the stovetop or in the microwave, stirring in butter and a splash of cream to bring back that silky, smooth texture. Some folks like to add a touch of cinnamon or maple syrup for extra warmth and flavor.
This make-ahead trick frees up valuable oven real estate on Thanksgiving Day and ensures you’ll have one less thing to worry about when the kitchen gets chaotic and guests start arriving hungry.
3. Homemade Green Bean Casserole (From Scratch)
Forget the canned soup version—making green bean casserole from scratch is easier than you think and tastes a million times better. The secret to making this dish ahead is preparing the creamy mushroom sauce and crispy fried shallots in advance.
Store both components separately in airtight containers in the fridge. On Thanksgiving Day, all you need to do is blanch fresh green beans, toss everything together, and bake until bubbly and golden.
This approach saves you precious oven space and time during the hectic holiday rush. Plus, your guests will be blown away by the rich, earthy flavors and crunchy topping that store-bought versions just can’t match. It’s comfort food elevated to a whole new level.
4. Potato Gratin (Scalloped Potatoes)
Potato gratin is the ultimate creamy, cheesy comfort food that everyone loves. Layering thinly sliced potatoes with cream, garlic, and cheese takes a bit of time, but here’s the trick: you can assemble and par-cook the entire dish up to three days ahead.
Just cover it tightly and refrigerate until Thanksgiving. On the big day, uncover it and finish browning the top in the oven until it’s golden and bubbly.
This method not only saves you time but also allows the flavors to meld together beautifully. The potatoes soak up all that garlicky cream, creating layers of pure deliciousness. Your guests will think you slaved away all day, but you’ll know the secret to staying calm and collected.
5. Roasted Sweet Potatoes with Miso-Maple Butter
Looking to add a modern twist to your Thanksgiving table? Roasted sweet potatoes with miso-maple butter bring a savory-sweet umami punch that will surprise and delight your guests. The genius move here is making the miso-maple sauce ahead of time.
Whisk together white miso paste, maple syrup, and softened butter, then store it in the fridge. On Thanksgiving, roast your sweet potato cubes until caramelized and tender, then toss them with the pre-made sauce.
This approach keeps your oven schedule flexible and ensures the potatoes stay crispy on the outside and fluffy inside. The combination of earthy miso and sweet maple creates a flavor profile that’s totally unique and memorable, making this dish a guaranteed conversation starter at your holiday feast.
6. Corn Casserole
Corn casserole is that creamy, slightly sweet, and utterly comforting dish that disappears fast at any holiday gathering. The texture is somewhere between cornbread and pudding, making it irresistible to kids and adults alike.
You can par-bake this casserole up to three days before Thanksgiving, which means mixing the corn, creamed corn, sour cream, butter, and cornbread mix, then baking it just until set. Cover and refrigerate until the big day.
On Thanksgiving, finish baking it until the top is golden and the center is hot and creamy. This two-step method ensures you don’t overcook it while also freeing up your schedule. It’s one of those dishes that tastes like pure nostalgia and warmth in every spoonful.
7. Cranberry Sauce
Did you know cranberry sauce actually tastes better after it’s had time to sit and develop its flavors? You can make this tangy-sweet condiment up to a week ahead and keep it chilled in the refrigerator, or even freeze it months in advance if you’re a super planner.
Fresh cranberries, sugar, and a bit of orange zest come together in just 15 minutes on the stovetop. The result is a bright, jewel-toned sauce that’s infinitely better than anything from a can.
Once it cools, the sauce thickens perfectly and the tartness mellows just enough. Having this ready ahead of time means one less pot on the stove and one more reason to feel confident and organized on Thanksgiving Day.
8. Make-Ahead Mashed Potatoes
Mashed potatoes are non-negotiable at Thanksgiving, but standing over a pot of boiling potatoes while everything else demands attention is nobody’s idea of fun. Here’s the solution: make them one to two days ahead, or even freeze them weeks in advance.
Boil, mash, and mix in your butter, cream, and seasonings as usual. Transfer to a baking dish, cover tightly, and refrigerate or freeze.
When it’s time to serve, gently reheat them in the oven or on the stovetop, stirring in a bit of extra butter or cream to restore that fluffy, dreamy texture. They’ll taste just as fresh and delicious as if you’d made them that very moment, and you’ll have saved yourself a ton of stress and cleanup.
9. Roasted Brussels Sprouts
Brussels sprouts have made a major comeback in recent years, and for good reason—when roasted properly, they become crispy, caramelized, and absolutely addictive. The prep work is the most time-consuming part: trimming the stems and slicing each sprout in half.
Luckily, you can do all of this up to two days ahead. Just store the prepped sprouts in an airtight container or zip-top bag in the fridge.
On Thanksgiving Day, toss them with olive oil, salt, and pepper, then roast at high heat until the edges turn golden brown and crispy. They cook quickly—usually in about 20 minutes—so you can time them perfectly with the rest of your meal. Even picky eaters might become Brussels sprouts fans after tasting these.
10. Mushroom or Apple-Sausage Stuffing Variations
Want to offer something a little different alongside your classic stuffing? Mushroom or apple-sausage variations add exciting flavors and textures that make your Thanksgiving table feel gourmet. The key to making these ahead is toasting your bread cubes and prepping all your add-ins—sautéed mushrooms, caramelized apples, cooked sausage, and herbs—several days early.
Store everything separately in the fridge. On Thanksgiving morning, toss it all together with broth and bake until golden and crispy on top.
This method keeps the bread from getting soggy and ensures every bite has the perfect balance of crispy edges and soft, flavorful center. Your guests will love having options, and you’ll love how organized and stress-free your kitchen feels.
