• 4 large sweet potatoes (about 2 lbs), peeled and cubed
• 1/2 cup brown sugar (brown sugar substitutes work as well!)
• 1/4 cup unsalted butter, softened (try coconut oil for a dairy-free option)
• 1/2 cup milk (almond or oat milk can be great alternatives)
• 1 teaspoon vanilla extract
• 1/2 teaspoon cinnamon
• 1/4 teaspoon nutmeg
• 1/2 cup mini marshmallows (optional, but highly recommended)
• 1/4 cup chopped pecans or walnuts (omit for a nut-free version)

• Cooking time: 30 minutes
• Baking time: 40 minutes
• Total time: 90 minutes

Step-by-Step Instructions

Step 1: Prepare the Sweet Potatoes

Start by preheating your oven to 350°F (175°C). While it’s warming, boil a large pot of water. Once boiling, add the cubed sweet potatoes. Cook for about 15-20 minutes until they’re tender. You’ll know they’re ready when you can easily pierce them with a fork.

Step 2: Mash and Mix

Drain the sweet potatoes and return them to the pot. Mash them until they’re smooth and creamy. Mix in the butter, brown sugar, milk, vanilla extract, cinnamon, and nutmeg. This step is where the magic happens—blend until you achieve a luscious texture.

Step 3: Assemble the Casserole

Transfer your sweet potato mixture into a greased 9×13 baking dish. Even out the top with a spatula. If you’re a fan of crunch, sprinkle chopped nuts over the top.

Step 4: Top with Marshmallows

This is optional, but let’s be real—who doesn’t love melted marshmallows? Evenly distribute the mini marshmallows over the mixture for that sweet, gooey finish.

Step 5: Bake to Perfection

Place the casserole in your preheated oven and bake for 30-40 minutes. The marshmallows should turn a beautiful golden brown. Allow it to cool for a few minutes before serving to get the perfect slice.
