Marshmallow Sweet Potato Casserole
Instructions
1
Poke holes all over the sweet potatoes with a fork and place them on a large microwave-safe plate. Microwave on high until the potatoes are very fork-tender, 15-20 minutes. Carefully remove the plate from the microwave and allow the sweet potatoes to cool until cool enough to handle, about 15 minutes. Microwave in batches if necessary.
2
Preheat the oven to 375°F.
3
Spray a 9x13-inch baking dish with nonstick cooking spray. Set aside.
4
Scoop the baked sweet potato flesh from the skins into a large mixing bowl. Discard the skins. Add the brown sugar, butter, cream or half and half, pumpkin pie spice, salt, and pepper. Mash the mixture with a potato masher or hand mixer until it is smooth and creamy. Add the beaten eggs to the bowl and stir to combine until smooth.
5
Transfer the sweet potato mixture to the prepared baking dish and smooth it into an even layer. Sprinkle the marshmallows evenly over the top.
6
Bake the casserole on middle rack of oven until the marshmallows are puffed and golden, and the dish is gently bubbling at the edges, 30-35 minutes.
7
Check to see that the casserole is done. Remove from oven or add time as needed.
8
Allow the sweet potato casserole to cool for 5-10 minutes before serving.

Tips & Tricks (5)
- Pre-Toast Marshmallows for Depth 🔥Lightly toast the miniature marshmallows in a dry skillet for 1-2 minutes before adding to the casserole to develop a subtle caramelized flavor that elevates the sweetness.
- Chill Sweet Potato Mixture Before Baking 🧊Refrigerate the sweet potato and cream mixture for at least 2 hours before adding marshmallows and baking; this prevents the custard from separating and ensures creamy, even texture.
- Add Marshmallows in the Final 10 Minutes ⏱️Wait until the casserole is nearly cooked before topping with marshmallows to prevent burning; they'll achieve perfect golden-brown peaks without charring the edges.
- Brown Your Butter for Complex Flavor 🧈Heat the butter until it turns golden-brown with a nutty aroma before incorporating it into the sweet potato base; this adds restaurant-quality depth that complements the spice profile.
- Use Room Temperature Eggs for Smooth Binding 🥚Bring eggs to room temperature before whisking into the mixture to ensure proper emulsification and prevent lumps in your custard-like casserole.
