If you have any ingredients leftover from this mini sweet potato casserole recipe, check out our Leftover Ingredients Recipe Finder.

  • Sweet potatoes: Use either cooked or canned sweet potatoes. You might like to use our Instant Pot sweet potato recipe to cook your sweet potato. If you’ve got an extra sweet potato, you’ll love using it in a small batch of Sweet Potato Fries or in a Sweet Potato and Black Bean Salad!
  • Brown sugar: This sweetens the sweet potatoes and gives them a delightfully subtle molasses flavor. If you don’t have brown sugar, use our small batch brown sugar recipe to make up a quick batch.
  • Ground cinnamon, nutmeg, salt, allspice, ginger, and cloves: These spices take these potatoes to a whole new level. Feel free to adjust the seasonings to suit your taste. If you don’t have all of the spices, you can use a pre-made pumpkin pie spice mix.
  • Egg: I use one large egg which is an important binder in a sweet potato casserole.
  • Pecans: These can be swapped with walnuts or almonds, or omitted for a nut-free version. You can enjoy leftover pecans in our pecan pie recipe!
  • Marshmallows: Some might consider the marshmallow topping to be the star of the dish! They add a sweet and creamy crust. If you have leftover marshmallows, consider using them in small batch Rice Krispies Treats or a mini S’mores Dip.

Recipe Variations

Flexibility is one of the great advantages of this recipe. There are many ways to personalize your small sweet potato casserole:

  1. Sweet Potato Casserole Without Nuts: If you’re allergic to nuts or simply prefer a nut-free version, you can leave out the pecans. The casserole will still have its characteristic creamy texture and sweet taste.
  2. Additional Toppings: Feel free to experiment with the toppings. Apart from marshmallows, you can also top the casserole with a sprinkling of brown sugar, a dash of cinnamon, or even some granola for an added crunch.
  3. Spice it up: For a spicier version, add a pinch of cayenne pepper or some chipotle powder to the sweet potato mixture before baking. It will give a nice, spicy kick that contrasts wonderfully with the sweetness of the dish.

    Made this recipe. it was really good. I’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.
