Step‑by‑Step Instructions for Sweet Potato Casserole with Marshmallows
Step 1: Preheat and Bake Sweet Potatoes
Begin by preheating your oven to 400°F (200°C). Wash and prick the sweet potatoes with a fork, then place them on a baking sheet. Bake for 40-45 minutes until they are tender when pierced with a fork. Once baked, allow them to cool slightly before peeling off the skin, preparing them for the casserole.
Step 2: Prepare the Baking Dish
Lower the oven temperature to 350°F (175°C) and grab a 2-quart baking dish. Generously grease the dish with unsalted butter to prevent sticking, ensuring every corner is coated. Set the baking dish aside as we prepare the sweet potato filling for the Sweet Potato Casserole with Marshmallows.
Step 3: Blend Sweet Potato Mixture
In a food processor, combine 2.5 of the peeled sweet potatoes with unsalted butter, milk, brown sugar, pure vanilla extract, cinnamon, salt, and eggs. Blend the ingredients until everything is smooth and creamy, taking about 2-3 minutes. This blend will provide the luscious base for your casserole, full of delicious flavors.
Step 4: Incorporate Additional Sweet Potato
Take the remaining half sweet potato and, using a fork or masher, mash it by hand to retain some texture. Gently fold this mashed potato into the blended mixture along with the zest of one orange. This step enhances the flavor profile, introducing a refreshing citrus note to your Sweet Potato Casserole with Marshmallows.
Step 5: Transfer Mixture to Baking Dish
Pour the combined sweet potato mixture into your greased baking dish, spreading it evenly with a spatula. The filling should be smooth and slightly fluffy. This creamy layer sets the foundation for the crunchy pecan crumble that awaits, making every forkful of the casserole a comforting delight.
Step 6: Prepare Pecan Crumble Topping
In a mixing bowl, combine chopped pecans, all-purpose flour, brown sugar, and a pinch of salt. Drizzle melted unsalted butter over the mixture, stirring until you achieve a clumpy texture. This topping will add a satisfying crunch to your Sweet Potato Casserole with Marshmallows while caramelizing beautifully during baking.
Step 7: Sprinkle and Bake
Evenly sprinkle the pecan crumble topping over the sweet potato mixture in the baking dish. Place the casserole in the oven and bake for 25-30 minutes, or until the center is set and the topping turns a delightful golden brown. The aroma wafting through your kitchen will surely tempt everyone to gather around the table.

Expert Tips for Sweet Potato Casserole
- Prepping Ahead: Make the Sweet Potato Casserole with Marshmallows a day in advance to enhance the flavors. Store it in the fridge without the topping until just before baking.
- Texture Variation: For a creamier consistency, ensure to blend the sweet potatoes thoroughly. Mashing in some by hand adds delightful texture—don’t skip that step!
- Butter Choice: Use unsalted butter to control the saltiness in your dish. Remember to grease your baking dish generously to avoid sticking.
- Bake Time Adjustment: If baking from frozen, double the baking time and check for doneness by inserting a knife into the center. It should come out clean.
- Flavor Boost: Experiment by adding a pinch of nutmeg along with the cinnamon for a warm, cozy spice that elevates the casserole’s flavors.

Sweet Potato Casserole with Pecan Crumble Recipe FAQs
What type of sweet potatoes should I use for the casserole?
Absolutely! For this Sweet Potato Casserole with Pecan Crumble, I recommend using firm, smooth sweet potatoes without any dark spots or blemishes. Look for those that feel heavy for their size and have a vibrant orange color. If you’re in a pinch, butternut squash can work as a substitute, providing similar sweetness and creaminess.
How long can I store leftovers of this casserole?
You can store leftover Sweet Potato Casserole in an airtight container in the fridge for up to 3 to 4 days. The flavors often meld beautifully as it sits, making it even more delicious! Just be sure to keep the topping crunchy; it’s best to warm the casserole up in the oven instead of the microwave when reheating to maintain the texture.
Can I freeze sweet potato casserole, and if so, how?
Yes, you can definitely freeze this casserole! To freeze, prepare the dish without the topping. Cover it tightly with aluminum foil or transfer it to an airtight container and freeze for up to 3 months. When you’re ready to bake, thaw it in the fridge overnight. Before baking, add the pecan crumble topping and bake at 350°F (175°C) until it’s golden and bubbly.
What if my casserole turns out too runny?
If your Sweet Potato Casserole with Pecan Crumble is too runny, it might be due to excessive liquid or not enough binding agents. To help thicken it, try adding an extra egg or a small amount of cornstarch mixed with water. If you find the mixture is too wet after baking, let it set for 10-15 minutes before serving. This will help it firm up a bit!
Can I make this dish gluten-free?
Very! You can easily make this casserole gluten-free by substituting all-purpose flour for almond flour in the pecan crumble topping. Additionally, make sure that any other ingredients, such as the baking dish and utensils, remain gluten-free to avoid cross-contamination. It’s a delicious variation that everyone can enjoy!
Is this recipe safe for pets, like dogs?
While sweet potatoes are safe for dogs in moderation, this casserole should be avoided for pets due to ingredients like brown sugar, butter, and eggs, which are not ideal for them. Always consult your veterinarian before sharing any human food with your furry friends to ensure it’s safe for their consumption.
