Ingredients
If you have any ingredients leftover from this mini Twice Baked Potato Casserole recipe, check out our Leftover Ingredients Recipe Finder.
- Russet Potato: One russet potato works best because it bakes up fluffy, making it easy to mash. If you have extra, use one in Potato Gnocchi, French Fries, Zuppa Toscana, or Potato Salad.
- Butter: Adds richness to the mashed potatoes.
- Sour Cream: Makes the potatoes creamy. Greek yogurt can be used instead. Extra sour cream can go into Broccoli Casserole, Corn Muffins, or a mini German Chocolate Cake.
- Milk: Helps create a smooth consistency. Any milk works.
- Salt and Pepper: Essential for seasoning—adjust to taste.
- Bacon: Brings a smoky flavor. Turkey or vegetarian bacon can be used. Leftover bacon is great in Crack Chicken, German Potato Salad, or Bacon, Egg and Cheese Cup.
- Cheese: Cheddar is a classic, but any cheese works. Shred your own for better melting. Leftover cheese can go into Shrimp and Grits or Mac and Cheese.
- Egg: Helps bind everything together.
Recipe Variations
Customize your small twice-baked potato casserole with these simple variations:
- Vegetarian: Omit the bacon and mix in spinach, broccoli, or mushrooms for extra flavor.
- Spicy: Stir in chopped jalapeños or a splash of hot sauce for some heat.
- Garlic Parmesan: Replace some cheddar with Parmesan and add minced garlic for a richer, savory flavor.
- Herb-Infused: Mix in fresh rosemary, thyme, or parsley for a fragrant touch.

These photos and instructions help you visualize how make this individual baked potato casserole. See the recipe box below for ingredient amounts and full recipe instructions.
- Prepare the Potato:
- Preheat your oven to 425°F (220°C).
- Scrub the potato clean and rinse it under cool running water. Pat it dry.
- Prick the potato several times with a fork.
- Place the potato on a baking sheet and bake for 40 to 50 minutes, until it’s completely soft when pierced with a fork.
- Let the potato cool on a wire rack.
Tip: You can bake the potato a day or two ahead and keep it in the fridge.
- Prepare the Filling: Reduce the oven temperature to 375°F (190°C). Once the potato has cooled, cut it in half lengthwise and scoop out the inside into a medium-sized bowl. Using an electric mixer on low speed or a potato masher, mash the potato.
3. Mix in the melted butter, sour cream, milk, salt, pepper, and the egg until well combined.
- Fold in the bacon and a little more than half of the shredded cheese.
- Assemble the Casserole: Generously butter a 10-ounce ramekin and fill it with the seasoned potato mixture. Top with the remaining shredded cheese. Place the ramekin on a rimmed baking sheet to catch any spills.
- Bake the Casserole: Bake until the cheese has melted and the casserole is heated through, about 25 minutes.
Expert Tips
- Best Potato Choice: Use a russet potato for the fluffiest texture. Its high starch content makes the filling creamy.
- Pierce Before Baking: Poke the potato with a fork before baking to release steam and prevent bursting.
- Room Temperature Ingredients: Let butter and sour cream sit out for 30 minutes before mixing for a smoother, creamier texture.
- Avoid Over-Mashing: Leave some small potato chunks for a better texture.
- Freezing Instructions: Cool completely, store in an airtight container, and freeze for up to 3 months.

I don’t see cream cheese in list of ingredients, but you say to remove it from fridge 30 minutes before mixing. Am I missing something? Can’t wait to try it.
Hi Sandra, Cream cheese is not in this recipe. We recommend that butter and sour cream be taken out of the fridge for easier mixing.
I really like the potato skin, and it’s really nutritious … seems like you are discarding it.
I love the potato skins too! They’re so nutritious and delicious. I usually snack on them while cooking. If you’d like to add them to the casserole, just chop the cooked potatoes with the skins and mix them in. Enjoy!
I prefer to put the mashed potato mixture back into the potato skin for the second bake.
I love twice baked potatoes but this will be easier and I can’t wait to make it~
I’m curious about why an egg is needed in this recipe. I’ve made 9×13 versions of loaded potato casserole and never used egg in it. What does the egg do here?
I like adding an egg because it adds richness and helps bind the ingredients together.
Great recipe.
Thank you!
