Ingredients
If you have any ingredients leftover from this sweet potato casserole for two, check out our Leftover Ingredients Recipe Finder.
- Sweet potatoes: Use cooked or canned. For a quick option, see our Instant Pot sweet potato recipe. Extra sweet potatoes can be used to make a small batch of sweet potato fries or a sweet potato and black bean salad.
- Brown sugar: Sweetens the casserole with a hint of molasses. Make your own with our small batch brown sugar recipe if needed.
- Spices (Cinnamon, Nutmeg, Salt, Allspice, Ginger, and Cloves): Add warm flavor to the dish. Use 2 teaspoons of pumpkin pie spice as a substitute.
- Egg: One large egg helps bind the casserole and gives it structure.
- Pecans: Provide crunch. Swap with walnuts or almonds, or leave out for a nut-free version. Leftovers work well in our small pecan pie or small batch pralines recipes.
- Marshmallows: Create the classic sweet, creamy topping. Extra marshmallows can be used in small batch rice krispies treats or a mini s’mores dip.
Recipe Variations
This small sweet potato casserole is easy to customize. Try these popular variations:
- Nut-Free: Omit the pecans for a nut-free version.
- Pecan Streusel Topping: Mix chopped pecans, 1 teaspoon brown sugar, 1 teaspoon granulated sugar, 1/4 cup of flour, and 3 tablespoons of butter (room temperature) for a crunchy streusel topping instead of marshmallows.
- Classic Marshmallow Topping: Stick with the traditional toasted marshmallow layer for a sweet, gooey finish.
How To Make A Mini Sweet Potato Casserole
These step-by-step photos show how to make a sweet potato casserole with marshmallows for two. See the recipe card below for exact amounts and instructions.
- Heat oven to 350°F (177°C). Lightly butter a 5×5-inch baking dish.
- Bake 1 large or 2 small sweet potatoes until tender, or use 1 cup canned sweet potatoes (drained and rinsed). Mash and place in a bowl.
- In a small bowl, mix brown sugar, cinnamon, nutmeg, allspice, ginger, cloves, and a pinch of salt. Stir into the mashed sweet potatoes.
- Add the beaten egg and mix well.
- Spread the mixture evenly in the prepared dish. Sprinkle pecans over the top. Bake for 15 minutes.

Expert Tips
- Mash Well: For the smoothest texture, mash the sweet potatoes thoroughly before adding other ingredients.
- Adjust Spices: Taste and adjust the spice blend to your preference. Pumpkin pie spice can be used as a shortcut.
- Cool Before Serving: Let the casserole rest for a few minutes after baking. This keeps the texture creamy and prevents burns.
- Check Doneness: Marshmallows should be puffed and golden, keep a close eye at the end of baking to avoid burning.

How much pumpkin pie spice would I use in place of the other spices?
Just found your website. Looking forward to trying your recipe. We are empty nesters. My husband and I don’t eat the same things. So it is nice to find recipes for one person.
God bless and thank you for your help
I’m so glad you found our site! Yes, you can absolutely use pumpkin pie spice instead. For this recipe, use about 2 teaspoons in place of the individual spices. It’ll give you the same warm flavor blend without needing to measure each one separately.
This was utterly delicious!!
I love trying U.S recipes and this was just lovely. Definitely be a regular treat for me!

I unexpectedly found myself alone for Thanksgiving so instead of feeling “blah” I decided to “fancy up” my holiday meal. It helped that I didn’t have to scale down our family favorites but could use recipes like this Mini-Sweet Potato casserole. The blend of spices was excellent. I’d never had both marshmallows AND pecan toppings in the same dish but this worked out quite nicely! The best of both worlds.
Thank you for sharing this! I’m so glad the recipe helped make your holiday special. I agree, the marshmallow and pecan topping is such a treat—so happy you enjoyed it!
Left off the marshmallows and added dried cranberries! Perfect for me.
Sounds wonderful! I’m so happy you enjoyed it.
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.
