How to Make Sweet Potato Casserole with Marshmallows

Follow these simple steps to prepare this delicious Sweet Potato Casserole with Marshmallows:

Step 1: Preheat and Prep
Begin by preheating your oven to 400?F (200?C). Line a baking sheet with foil (trust me, this will save you from a sticky mess later) and place your sweet potatoes on it. Prick them a few times with a fork to let them breathe during the baking process. Pop them in the oven and bake for about 40-50 minutes, depending on their size. Test with a fork?if it goes in easily, you?re golden.

Step 2: Cool Down
Once the sweet potatoes are done, carefully remove them from the oven. Lower the oven temperature to 350?F (175?C) and allow the sweet potatoes to cool for at least 20 minutes. This is the perfect time to sneak a taste of the creamy goodness inside.

Step 3: Mix the Base
In a large mixing bowl, whisk together the granulated sugar, melted butter, milk, vanilla extract, and salt. The goal here is to create a sweet, buttery mixture that?ll hug those sweet potatoes when they join the party.

Step 4: Mash it Up
Peel the sweet potatoes (careful, they will be hot) and throw them into the bowl with your butter-sugar mixture. Using a potato masher or a fork, mix and mash until everything is well blended. Be sure no lumps remain because we want a smooth, sumptuous base for our casserole. Finally, stir in the eggs until just combined.

Step 5: Bake the Casserole
Spread your sweet potato mixture into a small 20-ounce (0.6L) baking dish, smoothing it into an even layer. Bake in the preheated oven for about 20 minutes. Just enough time for your kitchen to start smelling like heaven.

Step 6: Marshmallow Finale
You are almost there! Remove the dish from the oven, and scatter your mini marshmallows across the top. Return it to the oven and bake for an additional 5-10 minutes, until the marshmallows are toasted and lightly golden brown. Keep an eye on them?suddenly, they can go from beautiful to burnt. When the marshmallows look perfectly puffy and gorgeous, take your dish out and prepare for the compliments that are sure to follow.

Dive in while it?s warm, perhaps with a sprinkle of cinnamon or a drizzle of caramel sauce if you?re feeling extra festive. Trust me, this Sweet Potato Casserole with Marshmallows isn?t just a side dish; it?s a showstopper at any meal, bringing everyone back for seconds. Just make sure to save some for yourself!
