Ingredients
Servings: 6–8
Prep Time: 20 minutes
Cook Time: 35–40 minutes
Oven Temperature: 375°F (190°C)
– 3 pounds russet potatoes: These are ideal for this recipe because they become fluffy and tender when boiled, creating a smooth, creamy potato base.
– 1/2 cup unsalted butter, melted: Adds rich buttery flavor and helps keep the potatoes moist and delicious.
– 1 cup sour cream: Gives the casserole its signature creamy texture with a subtle tang that balances the richness.
– 1/2 cup whole milk: Helps create a smooth, soft consistency without making the potatoes too heavy.
– 1 1/2 cups shredded cheddar cheese: Adds delicious cheesy flavor and melts into the potatoes, creating a rich and satisfying casserole.
– 2 large eggs: Help bind the potato mixture together and give it a slightly fluffy texture as it bakes.
– 1 teaspoon garlic powder: Adds a gentle savory flavor that complements the potatoes and cheese.
– 1 teaspoon salt: Enhances all the flavors.
– 1/2 teaspoon black pepper: Adds a little warmth and seasoning.
Instructions
Step 1: Prepare the Potatoes
Preheat your oven to 375°F (190°C). Lightly grease a 9 × 13-inch baking dish with butter.
Peel the russet potatoes and cut them into evenly sized chunks. Place them in a large pot, cover with cold salted water, and bring to a boil.
Cook for approximately 15–20 minutes, or until the potatoes are completely tender when pierced with a fork.
Step 2: Mash the Potatoes
Drain the potatoes thoroughly and return them to the pot.
Mash them until mostly smooth, removing any large lumps. Add the melted butter, sour cream, and milk.
Stir gently until the mixture becomes creamy and well combined.
Step 3: Add the Seasonings and Cheese
Add the garlic powder, salt, and black pepper.
Stir in 1 cup of shredded cheddar cheese, allowing it to distribute evenly throughout the warm potatoes.
Let the mixture cool slightly before adding the eggs.
Step 4: Incorporate the Eggs
In a small bowl, lightly beat the eggs.
Gradually stir them into the potato mixture until everything is thoroughly combined. Avoid adding the eggs while the potatoes are extremely hot, as this could scramble them.
Step 5: Assemble the Casserole
Transfer the creamy potato mixture into your prepared baking dish.
Spread it evenly with a spatula, creating a slightly textured surface with small peaks.
Sprinkle the remaining 1/2 cup of cheddar cheese over the top for an extra cheesy finish.
Step 6: Bake Until Golden
Place the casserole in the preheated oven and bake uncovered for 35–40 minutes, or until the center is set, the edges are bubbling, and the top is beautifully golden brown.
For extra color, broil for 1–2 minutes at the end, watching carefully to prevent burning.
Step 7: Rest and Serve
Remove the casserole from the oven and let it rest for approximately 5–10 minutes.
This allows the casserole to settle slightly, making it easier to serve.
Spoon generous portions onto plates and enjoy this delicious homemade comfort food while warm!

Pro Tips for the Best Baked Potato Casserole
Choose the right potatoes: Russet potatoes are excellent for a fluffy, creamy texture. Yukon Gold potatoes are another delicious option if you prefer a naturally buttery flavor.
Drain the potatoes well: Excess moisture can make your casserole watery. Let the drained potatoes sit for a minute before mashing.
Use room-temperature ingredients: Sour cream, milk, and eggs blend more easily when they aren’t ice-cold.
Don’t overmix: Mix just until everything is combined. Overworking potatoes can make them sticky or gummy.
Shred your own cheese: Freshly shredded cheddar generally melts more smoothly than pre-shredded cheese.
Create texture on top: Use a fork to make small ridges in the potato mixture. These edges brown beautifully during baking.
Let it rest before serving: Allowing the casserole to rest for a few minutes helps it hold together when scooped.

Frequently Asked Questions
Can I make baked potato casserole without sour cream?
Yes! You can substitute plain Greek yogurt or softened cream cheese. The flavor and consistency will be slightly different, but both work well.
