Ingredients
Scale
- 1.5 lbs steak (sirloin, ribeye, or your favorite cut)
- 1 tablespoon olive oil
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon paprika
- Salt to taste
- Black pepper to taste
- 5 lbs potatoes, peeled and thinly sliced
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 1/2 cup butter, melted
- 1/4 cup all-purpose flour
- 3 cups milk
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon nutmeg
- 3 cups shredded cheddar cheese, divided (reserve 1 cup for topping)
- 1/4 cup sour cream (optional)
- 2 tablespoons chopped fresh parsley, for garnish (optional)
Instructions
- Preheat oven to 375°F (190°C). Grease a 9×13 inch baking dish.
- In a bowl, combine the steak pieces with olive oil, garlic powder, onion powder, paprika, salt, and pepper. Mix well to ensure the steak is evenly coated.
- Heat a large skillet over medium-high heat. Add the seasoned steak and cook until browned on all sides, about 5-7 minutes. Set aside.
- In a large saucepan, melt the butter over medium heat. Add the chopped onion and cook until softened, about 5 minutes. Add the minced garlic and cook for another minute until fragrant.
- Whisk in the flour until smooth. Gradually add the milk, whisking constantly to prevent lumps. Continue whisking until the sauce thickens, about 5-7 minutes.
- Remove the saucepan from the heat. Stir in the salt, pepper, nutmeg, and 2 cups of the shredded cheddar cheese until melted and smooth. If using, stir in the sour cream.
- In the prepared baking dish, layer half of the sliced potatoes, followed by half of the cooked steak, and then half of the cheese sauce. Repeat the layers with the remaining potatoes, steak, and cheese sauce.
- Top with the reserved 1 cup of shredded cheddar cheese.
- Cover the baking dish with aluminum foil and bake for 45 minutes.
- Remove the foil and bake for an additional 15-20 minutes, or until the potatoes are tender and the cheese is melted, bubbly, and golden brown.
- Let the casserole rest for 10-15 minutes before serving. Garnish with fresh parsley, if desired.
Notes
Choose a steak with good marbling for flavor. Slice potatoes thinly for even cooking. Let the casserole rest before serving for better slice integrity.
