Prep & Cook Time

• Prep Time: 20 minutes
• Cook Time: 45–55 minutes
• Total Time: About 1 hour 15 minutes

Ingredients

For the Beef Mixture:

• 1 lb (450 g) ground beef
• 1 medium onion, diced
• 3 cloves garlic, minced
• 1 teaspoon paprika
• 1 teaspoon dried thyme
• 1 teaspoon salt
• ½ teaspoon black pepper
• 1 tablespoon tomato paste
• 1 cup beef broth

For the Potato Layer:

• 4 medium potatoes, thinly sliced
• 2 tablespoons olive oil or melted butter
• ½ teaspoon salt
• ½ teaspoon garlic powder

Cheese Sauce:

• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 2 cups milk
• 1 ½ cups shredded cheddar cheese
• ½ cup shredded mozzarella
• ½ teaspoon salt
• ¼ teaspoon black pepper

Step-by-Step Instructions

1. Prepare the beef mixture

Heat a large skillet over medium heat. Add the ground beef and cook until browned, breaking it up with a wooden spoon. Don’t rush this step—browning gives the beef that deep, savory flavor that makes this casserole taste richer.
Add diced onions and cook until soft and fragrant. Stir in garlic, paprika, thyme, salt, and pepper. Mix in the tomato paste, letting it cook for about a minute to deepen the flavor. Pour in the beef broth and let the mixture simmer for 5 minutes until slightly thickened.

2. Prep the potatoes

Slice the potatoes thinly and evenly—this ensures they cook at the same speed. Toss them with olive oil (or melted butter), salt, and garlic powder. Set aside.

3. Make the cheese sauce

In a medium saucepan, melt the butter. Whisk in the flour and cook for about 30 seconds—this step removes the raw flour taste. Slowly whisk in the milk, stirring constantly until the sauce thickens. Turn off the heat, then add cheddar, mozzarella, salt, and pepper. Stir until smooth and silky.

4. Assemble the bake

Preheat the oven to 375°F (190°C).
Grease a baking dish, then spread half the potato slices in an even layer. Spoon all the beef mixture over the potatoes. Pour about half the cheese sauce on top. Layer the remaining potatoes and finish with the rest of the cheese sauce, spreading it edge to edge so nothing dries out.

5. Bake

Cover with foil and bake for 30 minutes. Remove the foil, then bake for another 15–20 minutes until the top is golden, bubbly, and irresistible. Let it rest for 10 minutes before serving—this helps it set and makes cutting easier.

Tips & Tricks

• Slice potatoes thinly: Aim for about ⅛ inch thick. Thicker slices take longer to cook.
• Cook the beef fully before assembling: Any excess moisture can make the casserole watery.
• Let it rest after baking: Think lasagna rules—resting helps everything hold together.
• Mix cheeses for best flavor: Cheddar gives sharpness; mozzarella gives stretchiness.

Substitutions

• Ground beef: Swap with ground turkey, chicken, pork, or plant-based mince.
• Potatoes: Use sweet potatoes for a slightly sweet twist.
• Cheese: Try gouda, Monterey Jack, or pepper jack for a spicy kick.
• Milk: Use unsweetened almond milk or evaporated milk in place of whole milk.
• Gluten-free: Use cornstarch instead of flour for the cheese sauce.

Variations

• Spicy Version: Add sliced jalapeños, chili flakes, or pepper jack cheese.
• Vegetarian: Replace the beef with sautéed mushrooms, lentils, or a veggie mix.
• Italian Style: Add Italian seasoning and top with parmesan.
• Breakfast Casserole: Add scrambled eggs and breakfast sausage instead of ground beef.

Serving Suggestions

This dish pairs beautifully with:

• A fresh crisp salad
• Steamed green beans or roasted broccoli
• Garlic bread or warm dinner rolls
• A spoonful of sour cream or fresh chopped parsley on top

For gatherings, serve it family-style with a simple side of sautéed vegetables and a light dessert—something fruity or creamy balances the richness nicely.
