Ingredients

• 6 large russet potatoes
• 1/4 cup unsalted butter
• 4 oz cream cheese
• 2/3 cup sour cream
• 1/2 cup milk
• 1/2 teaspoon garlic powder
• Salt and pepper (to taste)
• 2 cups cheddar cheese (shredded)
• 1 1/2 cup smoked beef bacon (cooked and crumbled)
• 1/4 cup green onions (diced)

How to Make Loaded Baked Potato Casserole (Step-by-Step)

1. Preheat your oven to 375 degrees. Prepare a 9×13 casserole dish with nonstick cooking spray to prevent sticking and make cleanup easier.
2. Wash, peel, and dice 6 large russet potatoes into even pieces. Place them in a large pot, cover with water, and boil for about 15-20 minutes until potatoes are tender when pierced with a fork.
3. Drain the potatoes well and gently return them to the empty pot. Fold in 1/4 cup unsalted butter, 4 oz cream cheese, 2/3 cup sour cream, and 1/2 cup milk until creamy but not overworked.
4. Add seasonings of 1/2 teaspoon garlic powder, salt, and pepper to taste. Stir in 1 1/2 cups shredded cheddar cheese and 1 cup cooked, crumbled smoked beef bacon. Pour mixture into your prepared casserole dish.
5. Top the casserole with the remaining 1/2 cup cheese and 1/2 cup crumbled bacon for an irresistibly cheesy and savory crust. Bake uncovered for 25-30 minutes until bubbly and golden.
6. Remove from oven and sprinkle with 1/4 cup diced green onions. Serve immediately for a comforting, cheesy potato side dish.

The Secret to Perfect Texture: Boiled vs. Roasted Potatoes

For a Creamier, Softer Casserole (Boiled Method)

When potatoes are boiled until tender, they absorb moisture, swelling with softness. This method makes your casserole wonderfully creamy and smooth. After boiling, gently folding in butter, sour cream, and cheese creates a silky, comforting texture that melts in your mouth effortlessly.

For a Heartier, Fluffier Casserole (Roasted Method)

Roasting potatoes before mashing dries them slightly, resulting in a fluffier, drier mash that holds its shape better when baked. Roasted potatoes give the casserole a more rustic bite and enhance the natural sweetness of the potato, making each spoonful more textured and substantial.

Pro Tips for the Best Casserole

• Shred your own cheddar cheese for better melting and creamier texture—pre-shredded varieties often contain anti-caking agents that reduce melt quality.
• Soften cream cheese to room temperature before adding; it blends easier with the hot potatoes and prevents lumps.
• Reserve a little bacon grease when cooking bacon to stir into the casserole for an extra smoky, savory boost.
• Use nonstick spray liberally in your casserole dish to prevent sticking and ensure easy serving.

How to Avoid Gummy Potatoes: The Science!

The biggest risk to a perfect potato casserole is overworking your potatoes. When you mash or mix potatoes too vigorously, they release excess starch, which turns the dish gluey or gummy. That’s why this recipe emphasizes gently folding in the butter, cheeses, and seasonings rather than aggressive mashing. Think of it as a delicate embrace, preserving the fluffy and airy texture you want. The University of Illinois Extension offers further tips on avoiding common cooking pitfalls, including those related to starches.

Frequently Asked Questions

Yes, freeze before baking by wrapping it tightly. Bake from frozen, increasing cooking time by 10-15 minutes. Avoid freezing after baking as texture may suffer.
