How to Prepare Sweet Potato Casserole
Prepare Sweet Potatoes
Wash 4 to 5 medium sweet potatoes thoroughly. Peel and cut them into 1-inch cubes. Place cubes in a large pot and cover with cold water. Bring to a boil over high heat and cook for 15-20 minutes until the potatoes are fork-tender.
Create Smooth Potato Base
Drain the cooked sweet potatoes and return them to the pot. Mash until completely smooth using a potato masher or hand mixer. Add these ingredients to create a rich base:
Stir everything together until the mixture becomes creamy and well combined.
Prepare Baking Dish
Preheat your oven to 325°F (165°C). Grease a 9×13-inch baking dish with butter or cooking spray. Spread the sweet potato mixture evenly across the dish, smoothing the top with a spatula.
Bake Base Layer
Place the baking dish in the preheated oven. Bake uncovered for 25-30 minutes until the edges start to look slightly set and the center is warm.
Add Marshmallow Topping
Remove the casserole from the oven. Sprinkle 2 cups of mini marshmallows evenly across the surface. Return to the oven and bake for an additional 10-15 minutes until marshmallows turn golden and puffy.
Optional Toasting
For an extra crispy marshmallow top, switch your oven to broil. Place the casserole under the broiler for 1-2 minutes, watching carefully to prevent burning. The marshmallows should become golden brown and slightly caramelized.

Sweet Potato Casserole Q&A
Can sweet potatoes be replaced with canned ones?
Canned sweet potatoes work great! Drain them well and skip the boiling step. The texture might be slightly different, but the flavor remains delicious.
How do marshmallows stick to the sweet potato base?
The warm casserole helps marshmallows melt slightly and naturally adhere to the surface. Spread them evenly for the best coverage.
Are eggs necessary in this recipe?
Eggs help bind the casserole and create a creamy, rich texture. Without eggs, the dish might be looser and less structured.
Can sweet potato casserole be made ahead?
Prepare the base a day before, cover, and refrigerate. Add marshmallows just before baking to prevent them from getting soggy.
What size marshmallows work best?
Mini marshmallows melt more evenly and create a smooth top. Large marshmallows work too but might create uneven browning.
Should marshmallows completely cover the sweet potato layer?
Not necessary! Leave some sweet potato visible for a beautiful presentation and balanced marshmallow-to-potato ratio.

Ingredients
Primary Ingredients:
- 4 cups mashed sweet potatoes
- 2 large eggs
- 2 cups mini marshmallows
Supporting Ingredients:
- ½ cup white sugar
- ½ cup milk
- 4 tablespoons butter
Flavor Enhancers:
- ½ teaspoon salt
- ½ teaspoon vanilla extract
- ¼ teaspoon cinnamon or nutmeg
Instructions
- Gather 4 cups (about 4-5 medium) sweet potatoes, peeling and cutting them into 1-inch cubes. Submerge potatoes in a large pot of salted water, boiling for 15-20 minutes until fork-tender.
- Drain potatoes and mash thoroughly until no lumps remain. Transfer to a large mixing bowl containing ½ cup white sugar, 2 large lightly beaten eggs, ½ teaspoon salt, 4 tablespoons softened butter, ½ cup milk, and ½ teaspoon vanilla extract.
- Whisk all ingredients together until the mixture reaches a silky, consistent texture. Optional: Sprinkle ¼ teaspoon cinnamon or nutmeg for additional warmth.
- Preheat your oven to 325°F (165°C). Grease a 9×13-inch baking dish with butter or cooking spray, then spread the sweet potato mixture evenly across the surface.
- Bake uncovered for 25-30 minutes, allowing the casserole to set and develop a slightly firm consistency. Remove from the oven and immediately distribute 2 cups of mini marshmallows across the entire surface.
- Return the dish to the oven, baking for an additional 10-15 minutes until marshmallows transform into a golden, puffy layer.
- For extra caramelization, switch your oven to broil. Watch carefully and broil for 1-2 minutes until marshmallows achieve a deep golden-brown color. Serve warm.
Notes
- Cut sweet potatoes into uniform cubes to ensure even cooking and smooth mashing.
- Use a hand mixer or potato masher to create a creamy texture without overworking the potatoes.
- Watch marshmallows closely during final baking to prevent burning, as they can quickly go from golden to burnt.
- For a gluten-free version, confirm all ingredients are certified gluten-free and check marshmallow labels.
