  • Sweet potatoes: You can use cooked or canned sweet potatoes for this recipe. If you’re cooking them yourself, try our Instant Pot sweet potato recipe for a quick and easy option. Got extra sweet potatoes? Use them to make Sweet Potato Fries or in a Sweet Potato and Black Bean Salad!
  • Brown sugar: Adds sweetness and a subtle molasses flavor to the dish. If you don’t have brown sugar, you can quickly make some using our small batch brown sugar recipe to make up a quick batch.
  • Spices (Cinnamon, Nutmeg, Salt, Allspice, Ginger, and Cloves): These warm spices elevate the flavor of the sweet potatoes. Feel free to adjust the amounts to your liking. If you don’t have all of these spices, a pre-made pumpkin pie spice mix works as a great substitute.
  • Egg: One large egg acts as a binder, giving the casserole its structure.
  • Pecans: Add a lovely crunch. Swap them with walnuts or almonds, or leave them out entirely for a nut-free version. Leftover pecans are perfect for making our pecan pie recipe!
  • Marshmallows: The marshmallow topping creates a sweet and creamy crust that many consider the highlight of the dish. If you have extra marshmallows, try using them in small batch Rice Krispies Treats or a mini S’mores Dip.

  • Nut-Free Option: Skip the pecans for a nut-free version. The casserole will still be creamy and sweet, with all the comforting flavors intact.
  • Try Different Toppings: While marshmallows are a classic choice, you can experiment with other toppings like a sprinkle of brown sugar, a dash of cinnamon, or even granola for a crunchy twist.
  • Add a Spicy Kick: For a sweet-and-spicy contrast, mix a pinch of cayenne pepper or chipotle powder into the sweet potato mixture before baking. It’s a bold and delicious way to switch things up.

Frequently Asked Questions

Can I make a sweet potato casserole with canned sweet potatoes?

Yes, canned sweet potatoes work well. Be sure to drain the liquid and rinse the potatoes under cool running water before using them.

What is the best size baking dish to use?

A 5×5-inch baking dish or a 4×6-inch baking dish is perfect for this recipe. These sizes ensure the casserole bakes evenly and holds the right portion.

Can I make a sweet potato casserole recipe ahead of time?

Absolutely! Prepare the sweet potato mixture and store it in the baking dish (without marshmallows) in the refrigerator for up to a day. Add the marshmallows just before baking.

Can I double this recipe to serve more?

Absolutely! Simply double the ingredient amounts and use either two 5×5-inch baking dishes, one 6.5-inch square baking dish, or one 6×8-inch baking dish.

What can I use instead of marshmallows?

If you prefer, you can top the casserole with granola or a streusel topping, similar to the one we use in our Dutch Apple Pie recipe.

How should I store leftovers?

If you have leftovers from this mini sweet potato casserole, storing them is simple!
Let the casserole cool completely, then cover it tightly with plastic wrap or transfer it to an airtight container. Store it in the refrigerator for up to 3–4 days, and it will maintain its flavor and texture.
When you’re ready to reheat, remove the cover and warm it in a preheated oven at 350°F for about 15 minutes, or until heated through. Leftovers never tasted so good!

    Made this recipe. it was really good. Iโ€™m diabetic so I substituted monk brown sweeter for the brown sugar. Since I have to watch my carbs I divided into 2 ramekins. Next time will divide into 3 and use a little less of the cloves.
