How to Make Sweet Potato Casserole with vegan marshmallows
Step 1: Boil the Sweet Potatoes
Start by peeling and cutting your sweet potatoes into large chunks. Place them in a big saucepan, cover them with water, and bring it to a boil. Boiling helps to soften the potatoes quickly so they become fluffy when mashed.
Step 2: Mash the Potatoes
Once the sweet potatoes are fork-tender (they should fall apart easily), drain them and return them to the saucepan. Grab your potato masher and mash away! This step is crucial because it gives your casserole its creamy texture. Then add in the melted butter, brown sugar, salt, cinnamon, vanilla extract, and nutmeg. Mix until everything is well combined.
Step 3: Prepare the Pecan Topping
In a separate bowl, combine melted butter, brown sugar, all-purpose flour, salt, and pecan pieces. Stir until everything is thoroughly mixed. This topping adds a delightful crunch that perfectly complements the smooth filling.
Step 4: Assemble Your Casserole
Grease a 9 by 13 baking dish with cooking spray. Spread the sweet potato filling evenly across the bottom of the dish. Then sprinkle your pecan topping on top followed by an even layer of mini vegan marshmallows. This layering creates an irresistible contrast between textures!
Step 5: Bake Until Golden Brown
Preheat your oven to 350 degrees Fahrenheit. Bake your casserole for about 25-35 minutes or until it’s bubbly and the vegan marshmallows are golden brown on top. Keep an eye on it towards the end so you achieve that perfect golden hue without burning!
Enjoy sharing this Sweet Potato Casserole with vegan marshmallows at your next gathering—it’s sure to become a beloved tradition!
