Ingredients for Sweet Potato Casserole with Marshmallows
Here’s what you’ll need to make this delicious Sweet Potato Casserole with Marshmallows:
2 pounds sweet potatoes – Look for firm, smooth-skinned sweet potatoes, which provide natural sweetness and a creamy texture.
1/3 cup brown sugar – Choose lightly packed brown sugar for rich caramel notes that perfectly complement the sweet potatoes.
1/4 cup butter – Use unsalted butter for better control over the total salt content; this adds richness and flavor.
1/4 cup milk – Whole milk works best for creaminess, but you can substitute with almond or oat milk for dairy-free options.
2 large eggs – Eggs bind the casserole and provide a nice, fluffy texture once baked.
1/2 teaspoon vanilla extract – A splash of vanilla enhances the flavor profile and adds a comforting aroma.
1/2 teaspoon salt – This brings out the natural sweetness and balances flavors.
1/4 teaspoon cinnamon – Ground cinnamon adds warmth, enhancing the overall flavor of the casserole.
3 cups mini marshmallows – These sugary puffs create a toasty, gooey topping that’s the icing on the cake—er, the marshmallows on the casserole.
How to Make Sweet Potato Casserole with Marshmallows
Follow these simple steps to prepare this delicious Sweet Potato Casserole with Marshmallows:
Step 1: Prepare the Sweet Potatoes
Preheat your oven to 400°F (200°C). Line a sheet pan with foil for easy cleanup. Pierce the sweet potatoes all over with a fork to allow steam to escape while they bake.
Step 2: Bake the Sweet Potatoes
Place the sweet potatoes on the sheet pan and bake for 30-50 minutes, or until they are fork-tender. Keep an eye on them; you want them soft but not mushy.
Step 3: Cool and Scoop
Once baked, carefully cut the potatoes in half and let them cool for a few minutes. After they’re cool enough to touch, scoop the flesh into a medium mixing bowl.
Step 4: Mix the Ingredients
Reduce the oven temperature to 350°F (175°C). In the bowl with the sweet potato flesh, add the brown sugar, butter, milk, eggs, vanilla extract, salt, and cinnamon. Mix well until everything is combined and smooth.
Step 5: Bake the Casserole
Spread the sweet potato mixture evenly into a lightly greased medium (2-quart) casserole dish. Bake for 25-30 minutes, until heated through—resist the urge to dive in just yet!
Step 6: Add the Marshmallows and Toast
Remove the casserole from the oven and sprinkle the mini marshmallows over the top. Return to the oven and bake for an additional 10 minutes, or until the marshmallows are golden brown and bubbly.
Transfer to the table and brace yourself for compliments as you serve up this delightful dish. This Sweet Potato Casserole with Marshmallows will surely be a hit, making you the star of your holiday or family gathering!
