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 is ideal for this recipe because it becomes fluffy when baked, which is perfect for mashing. Got extra potatoes? Use one to make Potato Gnocchi, a small batch of French Fries, Zuppa Toscana, or Potato Salad.
- Butter: Adds richness to the mashed potato filling.
- Sour Cream: Gives the potatoes a creamy texture. Greek yogurt can be used as a substitute. If you’ve got extra sour cream leftover, consider using some in Broccoli Casserole, Corn Muffins, or a mini German Chocolate Cake.
- Milk: Helps to achieve the desired creamy consistency. Any type of milk will work.
- Salt and Pepper: Essential for seasoning. Adjust to your taste.
- Bacon: Adds a savory, smoky flavor. Turkey bacon or vegetarian bacon can be used. Extra bacon can be used in Crack Chicken, German Potato Salad, or Bacon, Egg and Cheese Cup.
- Cheese: Cheddar is a classic choice, but you can use any cheese you like. It’s best to shred your own cheese because pre-packaged cheese has ingredients that can prevent it from melting properly. Leftover cheese can be added to Shrimp and Grits or Mac and Cheese.
- Egg: One large egg helps bind the ingredients together.
Recipe Variations
Here are some ways to change up your loaded baked potato casserole to suit your taste:
- Vegetarian Version: Skip the bacon and add vegetables like spinach, broccoli, or mushrooms for extra flavor and nutrition.
- Spicy Twice Baked Potato Casserole: Add chopped jalapeños or a splash of hot sauce to the potato mixture for a kick of heat.
- Garlic Parmesan Potato Casserole: Swap some of the cheddar cheese for Parmesan and add minced garlic to the potato mixture for a rich, savory twist.
- Herb-Infused Potato Casserole: Mix in fresh herbs like rosemary, thyme, or parsley to add a fragrant, aromatic element to the dish.
How To Make Twice Baked Potato Casserole For One
These step-by-step 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.
Tip: I like to leave a few chunks, but you can mash it completely if you prefer.
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
- Starchy Spuds: For the fluffiest casserole, choose a russet potato. It’s high starch content helps create a creamy base.
- Perfect Prick: Before baking the potato, pierce it with a fork a few times. This allows steam to escape and prevents it from bursting.
- Room Temperature Rules: Take your cream cheese, butter, and sour cream out of the fridge at least 30 minutes before mixing. Room temperature ingredients blend smoother, creating a luxurious texture.
- Don’t Over-Mash: Leave some potato chunks for a delightful textural contrast.
- Freezing Instructions: This casserole freezes beautifully! Let it cool completely, transfer to an airtight container and freeze for up to 3 months.

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!
