How to Make Loaded Baked Potato Casserole

Ingredients

4 cups cooked potatoes, diced
2 cups sour cream
2 cups shredded sharp cheddar cheese
1/2 cup chopped green onions
1/4 cup melted butter
Salt and pepper, to taste
Optional: chives, crispy toppings (like breadcrumbs or crumbled bacon)

Instructions

Preheat oven: Set to 350°F (175°C). Grease a 9×13-inch casserole dish.
Prepare potatoes: In a large bowl, mix cooked potatoes with melted butter, salt, and pepper.
Layer casserole: Spread half the potato mixture in the dish. Top with half the sour cream and half the cheese. Repeat with the remaining ingredients.
Add toppings: Sprinkle green onions (and optional extras) over the top.
Bake: Cover with foil and bake for 30 minutes. Remove foil and bake another 10 minutes until cheese is bubbly and golden.
Serve: Let rest for a few minutes before slicing and serving hot.

Serving Suggestions

This casserole is filling enough to shine on its own, but it pairs beautifully with lighter sides. Serve with a crisp green salad for balance, grilled chicken or fish for added protein, or garlic bread if you’re going all-in on comfort food.

Tips for Success

Use Greek yogurt instead of sour cream for a lighter twist.
Don’t overcook potatoes during prep—keep them tender but firm.
Be generous with cheese for that classic gooey texture.

Storing & Reheating

Leftovers keep well for up to 3–4 days in the fridge. Reheat in the oven at 350°F (175°C) for about 20 minutes, or microwave single servings. To freeze, let the casserole cool completely before storing in an airtight, freezer-safe container for up to 3 months.

This Loaded Baked Potato Casserole is proof that comfort food doesn’t have to be complicated. Creamy, cheesy, and full of flavor, it’s the kind of dish that makes people smile—and keeps them coming back for seconds.
