There’s something undeniably comforting about a potato dish, especially when it’s loaded with all the flavors you love in a cozy, cheesy, creamy casserole. Twice Baked Potato Casserole takes the classic baked potato and elevates it to a hearty, family-style dish that’s perfect for dinner, holidays, or anytime you crave a warm, indulgent side. With fluffy mashed potatoes mixed with cheese, sour cream, bacon, and a touch of green onion, this casserole is an ultimate crowd-pleaser. It’s one of those recipes that brings smiles around the table and leaves everyone asking for seconds. The best part? It’s easy to make ahead of time and fits perfectly into a budget-friendly meal plan, especially if you’re cooking for two and can enjoy leftovers for lunch the next day.

Why do I love this recipe? The combination of creamy, cheesy potatoes with crisp bacon and savory seasonings is pure comfort food magic. Unlike regular baked potatoes, this casserole allows the flavors to meld together while staying rich and creamy, with just the right amount of texture from the cheese topping. It’s also incredibly versatile—you can adjust the mix-ins depending on what you have on hand, making it a perfect recipe for a budget-friendly, make-ahead dinner.

Serving suggestions: Serve this casserole as a side with roasted chicken, grilled steak, or even a simple green salad for a balanced meal. It also works beautifully as a brunch dish, paired with scrambled eggs or breakfast sausage. For a twist, add some steamed broccoli or sautéed mushrooms directly into the potato mixture to turn it into a one-dish meal.

Storage & Freezing: This casserole stores beautifully in the refrigerator for up to 4 days. Reheat in the oven at 350°F until warmed through, or microwave individual portions for a quick lunch. It also freezes well—assemble the casserole but don’t bake it, cover tightly with foil, and freeze for up to 2 months. When ready to enjoy, bake from frozen at 375°F until hot and bubbly, adding extra time as needed.

Variations of the recipe: You can swap regular cheddar for pepper jack, mozzarella, or Gruyère for a different flavor profile. Add caramelized onions, roasted red peppers, or fresh herbs like chives or parsley for a gourmet touch. For a lighter version, replace half the sour cream with Greek yogurt or use reduced-fat cheese.

Whether you’re cooking for a cozy night in or feeding a crowd, this Twice Baked Potato Casserole brings warmth, flavor, and comfort to the table every time.

Cuisine: American

Ingredients Method

Ingredients

5 lbs Yukon Gold potatoes baked and cooled
1/2 tsp kosher salt
1/2 tsp ground black pepper
2 lbs thick-cut bacon cooked and chopped
2 cups sour cream
2 cups shredded mozzarella cheese
2 cups shredded sharp cheddar cheese
4 green onions chopped

Method

Prep your ingredients:

Preheat your oven to 350°F. Grease a 9×13-inch baking dish with cooking spray and set aside. Pour the sour cream into a squeeze bottle for easy drizzling.

Prepare the potatoes:

Cut the baked Yukon Gold potatoes into bite-sized pieces.

First layer:

Place half of the cut potatoes in an even layer at the bottom of the baking dish. Sprinkle with salt and pepper. Layer half of the chopped bacon over the potatoes. Drizzle half of the sour cream over the bacon—don’t worry if it doesn’t cover every piece. Sprinkle half of the shredded cheddar and mozzarella cheeses evenly on top.

Second layer:

Add the remaining potatoes over the cheese. Sprinkle the rest of the bacon over this layer and drizzle with the remaining sour cream. Top with the remaining cheddar and mozzarella cheeses and finish with chopped green onions.

Bake the casserole:

Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. Remove the foil for the last 5 minutes of baking if you want the cheese on top slightly golden and bubbly.

Serve:
