1-Gathering and Prepping Ingredients: Start by preheating your oven to 375°F (190°C) and prepare all ingredients as outlined. Peel and thinly slice the 6 medium potatoes evenly for consistent cooking this step ensures every bite is tender and flavorful. In a large skillet over medium heat, melt 2 tablespoons of butter or cooking oil and sauté 1 diced onion, 2 minced garlic cloves, and 1 teaspoon of fresh thyme until the onion turns translucent and the garlic smells fragrant.

2-Gathering and Prepping Ingredients: Next, add 1 pound of ground beef to the skillet and cook until it’s browned, breaking it into small crumbles so there are no pink spots left. This is a key moment for your Ground Beef Potato Casserole, as proper browning locks in the flavors. Season the mixture with 1 teaspoon salt, 1 teaspoon bouillon powder, 1 teaspoon ground black pepper, 1 teaspoon paprika, and 1 teaspoon oregano for that perfect spice balance.

3-Building the Casserole Layers: After draining any excess fat, sprinkle 2 tablespoons of flour over the beef mixture and stir for about a minute to thicken things up. Gradually pour in 1 cup of beef broth and ½ cup of milk while stirring constantly until it forms a nice gravy. This gravy is what makes your Ground Beef Potato Casserole so comforting and rich.

4-Building the Casserole Layers: Grease a 9”x13” baking dish with butter or non-stick spray to prevent sticking. Layer half of the sliced potatoes in the dish, then spread half of the beef mixture on top for an even build. Repeat with the remaining potatoes and beef to create those signature layers. Cover the dish with foil and bake for about 45 minutes, or until the potatoes are tender this step ensures everything cooks through without drying out.

5-Finishing Touches: Once the baking time is up, remove the foil and sprinkle 1 cup of shredded cheddar cheese evenly over the top. Bake uncovered for another 10-15 minutes until the cheese melts and bubbles, giving your Ground Beef Potato Casserole that irresistible golden crust. Let it cool for a few minutes before serving, and garnish with chopped fresh parsley if you like a bit of color and freshness.
