How to Make Sweet Potato Casserole with Pecan Streusel
-
Prep Potatoes: Begin by peeling the sweet potatoes and cutting them into 1-inch chunks. This will help them cook evenly and mash smoothly.
-
Cook: Place the sweet potato chunks in a pot of salted water. Boil for about 15-20 minutes, or until they are fork-tender and easily mashable.
-
Drain and Cool: Once cooked, drain the potatoes in a colander and let them steam dry for 5-10 minutes. This ensures you won’t have a watery mash.
-
Make Streusel: In a mixing bowl, whisk together the flour, light brown sugar, granulated sugar, and ground cinnamon. Cut in the chilled butter until you achieve coarse crumbs, then stir in the chopped pecans.
-
Mash Potatoes: Using a potato masher, mash the drained potatoes until smooth. Mix in the unsalted butter, sugars, maple syrup, salt, cinnamon, and nutmeg until well combined.
-
Incorporate Eggs: Gradually mix in the eggs and heavy cream, stirring until just smooth. Be careful not to overmix to keep the texture fluffy.
-
Prepare for Baking: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish and evenly spread the mashed sweet potato mixture into the dish.
-
Initial Bake: Sprinkle the streusel topping generously over the sweet potato layer and bake in the preheated oven for 30 minutes, or until set and golden brown.
-
Add Marshmallows: After the initial bake, evenly distribute the mini marshmallows over the top of the casserole.
-
Final Bake/Broil: Bake for an additional 3-5 minutes, or broil for 60-90 seconds, until the marshmallows are puffed and beautifully golden. Keep an eye on them to prevent burning!
-
Rest and Serve: Allow the casserole to cool for 10-15 minutes before serving, letting the flavors meld a bit more.
Optional: Drizzle with additional maple syrup before serving for an extra touch of sweetness.

Expert Tips for Sweet Potato Casserole
-
Proper Potato Prep: Make sure sweet potatoes are dried thoroughly after boiling to prevent a watery mash, ensuring a creamy sweet potato casserole.
-
Cold Butter for Streusel: Keep your butter chilled while preparing the streusel. This helps achieve a flaky texture that adds crunch to your casserole.
-
Evenly Toasted Marshmallows: If you opt for mini marshmallows, distribute them evenly over the surface for quicker and more even toasting; this makes for a delightful topper.
-
Avoid Overmixing: When combining the egg and cream into the sweet potatoes, stir just until smooth. Overmixing can lead to a dense casserole instead of a fluffy one.
-
Moisture Control: If you notice excess moisture, a small amount of flour or cornstarch can help bind the mixture and maintain a perfect consistency.
Storage Tips for Sweet Potato Casserole
-
Room Temperature: If you plan to serve the casserole the same day, it can sit out for up to 2 hours before serving.
-
Fridge: Store any leftover Sweet Potato Casserole in an airtight container in the refrigerator for up to 3-4 days. Reheat in the oven or microwave before serving.
-
Freezer: The casserole can be frozen before baking; wrap it well in plastic wrap and aluminum foil for up to 3 months. Thaw overnight in the fridge before baking.
-
Reheating: To reheat, place the casserole in a preheated oven at 350°F (175°C) for about 25-30 minutes, or until warmed through, ensuring the topping remains crunchy.

How should I store leftovers from the casserole?
Leftover Sweet Potato Casserole can be stored in an airtight container in the refrigerator for up to 3-4 days. When you’re ready to enjoy it again, simply reheat in the oven at 350°F (175°C) to preserve the crunchy topping and creamy filling.
