Thanksgiving Side Dishes to Prep in Advance!
Thanksgiving side dishes don’t have to be last-minute miracles! This year, let’s work smarter, not harder. Here are some delightful Thanksgiving side dishes that’ll free up oven space, ease your stress, and make Thanksgiving enjoyable.
1. Classic Green Bean Casserole
There’s a reason this casserole appears on so many holiday tables. It’s creamy, crunchy, and has everyone reaching for seconds. Even better, you can assemble it a day or two before Thanksgiving day.

Ingredients:
- 1 lb fresh green beans (or canned if you’re in a pinch)
- 1 can cream of mushroom soup
- 1/2 cup milk
- 1 tsp soy sauce
- Black pepper, to taste
- 1 1/2 cups crispy fried onions
Instructions:
- Blanch your green beans (if using fresh) to get them nice and tender.
- In a mixing bowl, combine soup, milk, soy sauce, and pepper. Fold in green beans and half the fried onions.
- Transfer the mixture to a baking dish, cover tightly, and refrigerate.
- When Thanksgiving dinner arrives, reheat it before serving. Bake at 350°F for 25 minutes, then sprinkle with remaining onions and bake for another 5 minutes.
💡 Pro Tip: If you’re short on oven space, try baking this casserole in a toaster oven or even an air fryer!
2. Sausage and Herb Stuffing

The hearty bread, juicy sausage, and fresh herbs create a comforting side worth every effort. Stuffing made from scratch is so much better than boxed, and it’s a breeze to prep ahead. You can prepare this dish a day or two in advance, then just heat it before serving.
Ingredients:
- 1 lb Italian sausage, removed from casings
- 1 loaf of French or sourdough bread, cubed
- 1 large onion, chopped
- 2 ribs celery, chopped
- 1/4 cup fresh parsley, chopped
- 1 tsp sage
- 1 tsp thyme
- 3 cups chicken or turkey broth
Instructions:
- Brown the sausage in a large skillet, then set aside.
- In the same skillet, sauté onions and celery until tender. Combine with sausage, bread cubes, herbs, and broth until the bread is moistened.
- Transfer to a greased baking dish, cover, and refrigerate until ready to serve.
- Bake at 350°F for 30 minutes until golden and heated through.
💡 Pro Tip: If you like a more cohesive stuffing, add an egg or two to bind the ingredients together.
3. Creamy Mashed Potatoes
Who doesn’t love a bowl of buttery mashed potatoes? However, peeling and mashing potatoes on Thanksgiving Day can add stress and mess! You can make these up to two days ahead, store them in the fridge, and reheat to serve.
