Ingredient Notes & Substitutions
Sweet Potatoes
Use orange-fleshed sweet potatoes for best flavor and texture. Russet or white potatoes won’t work as well.
Substitutions: Butternut squash for a different flavor profile.
Mini Marshmallows
Mini marshmallows melt evenly and create a smoother topping than large marshmallows. Avoid using marshmallow fluff.
Substitutions: Use vegan marshmallows for a dairy-free version.
Brown Sugar
Adds caramel-like depth. Light or dark brown sugar both work—adjust to taste.
Substitutions: Coconut sugar or maple syrup for a less processed option.
Milk
Dairy or non-dairy milk works. Full-fat milk creates a richer texture.
Substitutions: Heavy cream, almond milk, or oat milk.
Pro Tips for Perfect Sweet Potato Casserole
Mashing Technique
For a smooth base, use a stand mixer with a paddle attachment. For chunky texture, mash by hand.
Baking Hack
Preheat oven for 15 minutes before placing casserole in to ensure even caramelization of marshmallows.
Make-Ahead Tip
Assemble casserole up to 24 hours in advance. Add marshmallows and bake just before serving.
Flavor Boost
Add a pinch of nutmeg or a splash of maple syrup for extra warmth.
Variations & Customizations
Vegan Version
Use vegan butter, non-dairy milk, and vegan marshmallows. Substitute brown sugar with coconut sugar.
Gluten-Free Option
Ensure all packaged ingredients are certified gluten-free. The base is naturally gluten-free.
Spiced Up
Add a dash of cayenne pepper or smoked paprika to the sweet potato mixture for a spicy kick.
Crumble Topping
Skip marshmallows and use a streusel topping made with oats, brown sugar, and butter for a crunchier finish.

Make-Ahead Instructions & Storage
Make-Ahead Tips
Assemble the casserole base up to 24 hours in advance. Store covered in the refrigerator. Add marshmallows and bake just before serving.
Refrigerator Storage
Store leftovers in an airtight container for up to 3 days. Reheat in a 350°F oven to restore texture.
Freezer Storage
Freeze unbaked casserole for up to 2 months. Thaw overnight in the fridge before adding marshmallows and baking.
Reheating Instructions
Reheat in the oven at 350°F for 20–25 minutes. Avoid microwave use to prevent the marshmallow topping from becoming rubbery.
Troubleshooting & Common Questions
Q: Can I use large marshmallows instead of mini?
A: Mini marshmallows melt more evenly. Large marshmallows may create uneven texture and risk burning.
Q: How do I prevent the marshmallows from burning?
A: Cover the casserole with aluminum foil during the first 20 minutes of baking. Remove foil for the last 10 minutes to allow browning.
Q: Can I add nuts to the topping?
A: Yes! Toasted pecans or walnuts add a nice crunch. Sprinkle them over the marshmallows before baking.
Q: Is there a way to make this healthier?
A: Use Greek yogurt instead of butter for a lighter version. Reduce brown sugar by 25% for less sweetness.
