Ingredients
Sauce
- 1/4 cup salted butter
- 1 medium white onion, finely diced
- 1/4 cup all-purpose flour
- 1 cup chicken broth
- 1 cup heavy cream
- 1 cup sour cream
- 4 ounces diced green chiles
- 1 tablespoon garlic powder
- 1 teaspoon hot sauce (Tabasco or similar)
- 1 teaspoon black pepper
- 1 teaspoon salt
Casserole
- 2 pounds ground beef
- 3-4 large russet potatoes, peeled and thinly sliced
- 1 teaspoon salt
- 1 teaspoon black pepper
- 2 cups shredded cheddar cheese
Instructions
- Prepare the Sauce: In a saucepan, melt the salted butter over medium heat. Add the finely diced white onion and sauté until translucent and soft. Sprinkle in the all-purpose flour and stir continuously to create a roux, cooking for about 2 minutes without browning. Gradually whisk in the chicken broth and heavy cream, stirring until the mixture thickens to a creamy consistency. Remove from heat and stir in the sour cream, diced green chiles, garlic powder, hot sauce, black pepper, and salt, mixing thoroughly to combine all flavors.
- Cook the Ground Beef: In a large skillet over medium-high heat, cook the ground beef until browned, breaking it apart evenly with a spatula. Season with salt and black pepper. Drain excess fat if necessary.
- Assemble the Casserole: Preheat your oven to 375°F (190°C). In a greased casserole dish, layer the thinly sliced russet potatoes evenly on the bottom. Follow with a layer of the cooked ground beef. Pour half of the prepared creamy sauce over the beef layer. Repeat the layering with the remaining potatoes, beef, and sauce, ensuring an even spread.
- Add Cheese and Bake: Sprinkle the shredded cheddar cheese evenly on top of the assembled casserole. Cover with foil and bake in the preheated oven for 45 minutes. Remove the foil and bake for an additional 15 minutes or until the cheese is golden brown and bubbly, and the potatoes are tender when pierced with a fork.
- Rest and Serve: Allow the casserole to rest for 10 minutes after baking to set. This makes serving easier and helps the flavors meld. Serve warm as a hearty main dish perfect for family dinners.
Notes
- For a spicier dish, increase the amount of diced green chiles or hot sauce.
- Russet potatoes work best due to their starchy texture, which helps the layers hold together after baking.
- Ensure potatoes are sliced thinly and uniformly for even cooking.
- This casserole can be prepared a day ahead and refrigerated; just add an extra 10 minutes to the baking time when reheating.
- To reduce calories, substitute heavy cream with half-and-half and use reduced-fat sour cream and cheese.
