Instructions to Make Sweet Potato Casserole with Pecan Streusel for Thanksgiving
Let’s walk through this Sweet Potato Casserole with Pecan Streusel for Thanksgiving step by step — from peeling those sweet potatoes to pulling a bubbling, golden casserole out of the oven. Whether it’s your first Thanksgiving hosting or your tenth, these detailed step-by-step directions will make you feel confident and calm in the kitchen.
Step 1: Prep and Boil the Sweet Potatoes
Start your step-by-step journey by preheating the oven to 350°F (175°C). Grab four large sweet potatoes, peel them, and chop them into evenly sized chunks — about 2-inch cubes. This helps them cook faster and more evenly. Place them in a large pot and cover with cold water. Add a pinch of salt (it brings out the natural sweetness later). Bring to a boil over medium-high heat, then lower the heat and simmer for 15 to 20 minutes until the potatoes are fork-tender. Drain well, and give them a minute or two to steam dry — excess water can make your casserole mushy. For more tips on choosing the best sweet potatoes, you can check out my Southern Sweet Potato Casserole guide.
Step 2: Mash and Mix the Sweet Potato Base
Next, in this step-by-step process, transfer the drained sweet potatoes to a large mixing bowl while they’re still hot — warmth helps melt the butter and blend the ingredients more smoothly. Use a potato masher or hand mixer to mash until silky and lump-free. Add ½ cup sugar, ¼ cup melted unsalted butter, ½ cup milk, 2 eggs, 1 teaspoon vanilla, ½ teaspoon cinnamon, ¼ teaspoon nutmeg, and ¼ teaspoon salt. Stir everything together until the mixture becomes creamy and rich. You’re aiming for a consistency that’s thick but spreadable — similar to pancake batter. If your potatoes seem too dry, add a splash more milk. For a dairy-free version, you can substitute with almond or oat milk (see my Creamy Vegan Potato Soup for more dairy-free inspiration).
Step 3: Create the Pecan Streusel Topping
Now it’s time for the best part — the pecan streusel. In another bowl, combine 1 cup chopped pecans, ½ cup all-purpose flour, ½ cup light brown sugar, ¼ teaspoon cinnamon, and ¼ teaspoon salt. Add 6 tablespoons of cold butter (cut into small cubes). Using your fingers or a pastry cutter, work the butter into the mixture until it forms coarse crumbs — some pea-sized chunks are ideal. This step-by-step process gives you that irresistible crumble that bakes into a crisp, buttery topping. If you’re looking for a nut-free variation, swap the pecans with rolled oats or crushed cornflakes for crunch. For flavor inspiration, check out my Crock Pot Candied Yams where I use a similar sweet, buttery topping.
Step 4: Assemble the Casserole
Lightly grease a 9×13-inch baking dish with butter or nonstick spray — you don’t want your masterpiece sticking! Spread the sweet potato mixture evenly in the dish, smoothing the top with a spatula. Then, sprinkle the pecan streusel mixture evenly across the surface. Don’t press it down — letting it sit loosely helps it bake up extra crisp. This step-by-step assembly is where all your effort comes together beautifully. The vibrant orange base and nutty topping will already look stunning — and trust me, it only gets better from here.
Step 5: Bake to Golden Perfection
Slide your casserole into the preheated oven and bake for 30 to 40 minutes, until the topping turns a deep golden brown and the filling bubbles slightly at the edges. The smell alone — toasted pecans, brown sugar, and cinnamon — will make your kitchen feel like Thanksgiving heaven. Keep an eye on it during the last few minutes; if the top browns too quickly, lightly tent it with foil. Following this step-by-step baking process ensures that the streusel stays crunchy while the sweet potatoes remain moist and fluffy.
Step 6: Cool, Serve, and Enjoy
Once baked, remove the casserole and let it rest for at least 10 minutes. This helps the topping set and makes it easier to slice and serve. Serve warm alongside turkey, mashed potatoes, or a tangy side like my Cranberry Orange Glazed Turkey Breast. This step-by-step cooling and serving process might seem simple, but patience really pays off — that first warm bite will be pure comfort and nostalgia.
Bonus Step: Make-Ahead and Storage Tips
If you’re planning ahead, this step-by-step guide works perfectly for prep. Assemble the casserole (without baking), cover tightly, and refrigerate overnight. When ready to bake, let it sit at room temperature for about 20 minutes and add 5–10 extra minutes of baking time. You can even freeze it for up to a month — just wrap it well in foil and bake from frozen at 325°F until hot and bubbly.

Key Tips for Making Sweet Potato Casserole with Pecan Streusel for Thanksgiving
- Choose the right potatoes: Look for firm, deep orange sweet potatoes — they mash smoothly and taste naturally sweet.
- Don’t overcook: Boil just until tender. Overcooking can make them watery, affecting the texture.
- Use cold butter for the streusel: This is key for that crisp, crumbly topping we all love.
- Make ahead: Assemble the casserole (without baking) a day in advance, cover, and refrigerate. Add 5–10 extra minutes of baking time when ready.
- Customize: Swap pecans for walnuts or add a touch of maple syrup for a richer flavor.
Storage and Reheating Tips for Sweet Potato Casserole with Pecan Streusel for Thanksgiving
Got leftovers? Lucky you. Store any remaining casserole in an airtight container in the fridge for up to 4 days. To reheat, cover with foil and warm in a 350°F oven for about 15 minutes — this keeps the streusel crisp while reheating the filling evenly. If you’re freezing it, wrap it tightly (before or after baking) and freeze for up to a month. Reheat from frozen at 325°F until warmed through. For smaller portions, the microwave works fine too — just heat in short intervals to avoid drying it out.
FAQs
