Allrecipes' editorial guidelines Updated on October 20, 2023 Close Photo: Tamara B I'm going to go out on a limb here and say Thanksgiving Day side dishes are the best part of the holiday meal. From decadent sweet potato casseroles to ooey-gooey mac and cheese, turkey-day side dishes are the pinnacle of comfort food to be thankful for. Even better? Most sides can take casserole form, which is great because casseroles tend to be less fussy and you can throw a bunch of them in the oven at once. Plus, many casseroles work well as make-ahead dishes, which can seriously trim down your to-do list on the day of Thanksgiving. We rounded up some of our favorite make-ahead casseroles for Thanksgiving dinner so you can focus on that turkey. 01 of 11 French Onion Green Bean Casserole View Recipe KathyBarbieri This updated version of a traditional favorite includes fresh green beans, a creamy homemade white sauce, and a crisp topping with two kinds of cheese. It's a perfect make-ahead candidate because it takes a little extra time to make when you're not just dumping canned ingredients into a baking dish.

(Is there anything mac and cheese doesn't improve?) According to many reviewers, you can leave out the jalapenos to appease more sensitive palates. Emily Righter even substituted jalapenos with peas, which pleased even her picky eaters. Virginia Lee Kanzler came up with a clever way to keep this warm for transporting it to a potluck; After assembling, she threw it in her slow cooker on the warm setting rather than baking it. If you're short on Thanksgiving day oven space, this could seriously simplify things! 03 of 11 Awesome and Easy Creamy Corn Casserole View Recipe My Hot Southern Mess When it comes to recipes, awesome, easy, and creamy are a few of our favorite words. Recipe creator LETSGGGO says: "I know you will love the ease of preparation and especially the taste. Everyone always wants the recipe!" If you want to get a head start on this crowd-pleaser, MommyFromSeattle—who says she has been making this recipe for years—notes that it can be made ahead and refrigerated before baking. Simply let it sit out on the counter for 30 to 45 minutes before putting in the oven to let it get to room temperature. Make-ahead Thanksgiving casserole for the win! 04 of 11 Yummy Sweet Potato Casserole View Recipe Preethi Venkatram/Allrecipes This wildly popular five-star recipe has been marked as "made" 6,000 times and has more than 2,000 positive reviews! Recipe creator TINA B says that her family begs her to make it every year, and that the secret is the pecan topping. (Indeed, lots of folks commented that they doubled the topping.) Many reviewers suggest roasting the potatoes for extra flavor, and quite a few still found it plenty sweet even if they cut the sugar in half. Gunia20 says: "This was a hit. Not too sweet at all. I made the casserole the day before and stored it in the fridge overnight. Made the topping the next day and threw it in the oven for 30 minutes." 05 of 11 Cranberry, Sausage, and Apple Stuffing View Recipe beccajulia This makes enough stuffing for a 14-pound turkey plus extra on the side, so you might want to cut the recipe in half. LADY_MARMALAADE says: "This stuffing was incredible! I think that it was one of my most complimented cooking efforts—and I cook all the time." 06 of 11 Mom's Sausage and Cornbread Dressing View Recipe "This recipe is not a quick side dish," recipe submitter 4620nellerd says. "It needs time and work for prep and cooking, but is very worth it." Refrigerate this classic cornbread stuffing, baked or unbaked, for up to two days. The Best Thanksgiving Stuffing and Dressing Recipes 07 of 11 Garlic Mashed Potato Casserole View Recipe Soup Loving Nicole What is one the most time-consuming, dish-dirtying, labor-intensive things to make on Thanksgiving? If you said mashed potatoes, you're right! So do yourself a favor and add mashers to your make-ahead list. Home cook tifray says: "I made this the day before serving it. I wanted mashed potatoes but didn't want to be stuck in the kitchen when company was here!" 08 of 11 Garlic Potatoes Gratin View Recipe naples34102 If you prefer a cheesier potato dish (we wouldn't blame you), our Garlic Potatoes Gratin reigns as a Thanksgiving favorite. And if you're making more than one dish ahead of time, get a head start on this one. "The cooking time was low and slow, not only giving me ample 'hands-free' time to prepare the rest of our dinner, but it almost guaranteed the potatoes would be cooked through with deliciously melded flavors," naples34102 says. Our 20 Best Thanksgiving Potato Recipes 09 of 11 Amazing Spinach Artichoke Casserole View Recipe DPHELPS A classic spinach casserole made with cream cheese, sour cream, and mayonnaise will stand stand out against casseroles that call for creamy soups. "This recipe has a lot of steps, but it is relatively easy and is well worth it," recipe creator mharbold says. "... This is my most requested vegetable casserole recipe, and it is a Thanksgiving favorite." 10 of 11 Make-Ahead Turnip Casserole View Recipe Rita This buttery turnip casserole has "crowd-pleaser" written all over it. A touch of brown sugar brings out the natural sweetness of the turnips and a toasty breadcrumb topping brings a satisfying crunch. And as reviewer Brynnygirl points out, it's a great way to introduce turnips to pickier eaters at your table. 11 of 11 More Inspiration Meredith Food Studios 15 Thanksgiving Recipes You Can Make in Your 9x13 Dish 9 Make-Ahead Thanksgiving Sides That Hold Up in the Freezer 50 Best Thanksgiving Side Dishes Was this page helpful?
