How to Make Sweet Potato Casserole with Streusel Topping
Follow these simple steps to prepare this delicious Sweet Potato Casserole with Streusel Topping:
Step 1: Preheat the Oven
Set your oven to preheat at 375°F (190°C). While it’s warming up, grab a 2 or 2½ quart casserole dish and grease it lightly to ensure easy serving later.
Step 2: Boil the Sweet Potatoes
Take those sweet potatoes and place them in a large pot. Cover with water and bring to a boil. Let them cook until they’re tender, about 7 minutes. Drain and return them to the pot.
Step 3: Mash the Sweet Potatoes
Add the butter, milk, ground cinnamon, brown sugar, and salt to the sweet potatoes. Mash everything up until it’s as smooth as a baby’s bottom, then spread the mash evenly in your prepared casserole dish.
Step 4: Heat Everything Through
Pop that casserole in the oven. If it was warm beforehand, let it heat for 5-10 minutes. If it’s been resting in the fridge, give it a hearty 30 minutes until heated through.
Step 5: Make the Streusel Topping
In a medium bowl, combine the softened butter, brown sugar, flour, cinnamon, and salt. Add in those chopped pecans and mix until crumbly and beautiful—just like you!
Step 6: Layer and Bake Again
Remove the warm sweet potatoes from the oven. Top them generously with half of the mini marshmallows, sprinkle half of the streusel topping over, then repeat with the remaining marshmallows and streusel.
Step 7: Bake to Perfection
Return your casserole to the oven and bake for 8-15 minutes, or until you see that topping turn a stunning golden brown. Let it rest at room temperature before serving, allowing those flavors to settle in nicely.
