How to Make Sweet Potato Casserole with vegan marshmallows and Pecans
Step 1: Prepare the Sweet Potatoes
Preheat your oven to 375°F. Start by boiling your peeled sweet potatoes until they are tender. This usually takes about 15-20 minutes. Once they’re cooked through, drain them well and mash them until smooth. This step is crucial because it creates the creamy base that makes your casserole so comforting.
Step 2: Mix Your Ingredients
In a large bowl, combine your mashed sweet potatoes with softened butter, sour cream, pumpkin puree, brown sugar, cinnamon, nutmeg, vanilla extract, and salt. Mix everything together until smooth and creamy. Spreading this mixture into a greased 9×13 dish sets the stage for your delicious toppings!
Step 3: Make the Topping
In another bowl, mix together chopped pecans, brown sugar, flour, and cold butter until crumbly. This mix will add a delightful crunch on top of your casserole. Sprinkle it evenly over the sweet potato mixture before placing it in the oven.
Step 4: Bake It Up
Bake your casserole in the preheated oven for about 25-30 minutes until it’s bubbly and golden on top. This step allows all those flavors to meld together beautifully while creating that perfect crispy crust.
Step 5: Toast Those Marshmallows
Lastly, remove your casserole from the oven and sprinkle mini vegan marshmallows on top. Broil it for an additional 2-4 minutes until golden brown—watching closely so they don’t burn! Let it rest for about 10 minutes before serving; this allows everything to settle while keeping those marshmallows fluffy.
And there you have it! A delightful Sweet Potato Casserole with vegan marshmallows and Pecans that will surely become a cherished recipe in your kitchen!
