Step-by-Step Instructions to Make Sweet Potato Casserole with Marshmallows
Step 1 – Prep Your Ingredients
Start by peeling and chopping the sweet potatoes. Place them in a pot of salted water and let them boil until fork-tender. This usually takes about 15-20 minutes. Once cooked, drain and mash them until they’re smooth.
Step 2 – Start Cooking
As your sweet potatoes cool a bit, preheat your oven to 350°F (175°C). In a separate bowl, mix the mashed sweet potatoes with melted butter, coconut milk, eggs, vanilla extract, sweetener, cinnamon, and nutmeg. Make sure to blend until it’s creamy and fully combined.
Step 3 – Combine and Finish Cooking
Transfer the mixture into a greased baking dish, smoothing the top with a spatula for an even finish. Sprinkle the sugar-free marshmallows on top evenly, creating a delightful layer that will become perfectly toasted in the oven.
Step 4 – Serve and Enjoy
Bake the casserole in the preheated oven for about 25-30 minutes, or until the marshmallows are golden brown and toasty. Once done, let it cool for a few minutes before serving. Enjoy this delectable dish with family or friends!
