1. Preheat Oven: Set your oven to 375°F (190°C) and grease a 9×13-inch baking dish.

2. Season and Shape Patties: Mix 1½ lbs ground beef with ½ tsp garlic powder, ½ tsp onion powder, salt, and pepper. Form into 6 patties.

3. Brown Patties: In a skillet over medium-high heat, brown the patties on both sides. Set them aside.

4. Prepare Gravy: In the same skillet, whisk together 1 cup milk and ¼ cup flour until smooth. Gradually add the remaining 1 cup milk, stirring until the gravy thickens. Season if needed.

5. Assemble Layers:

• Layer half of the thinly sliced 4–5 potatoes and 1 sliced onion at the bottom of the baking dish.
• Place the browned patties on top.
• Add the remaining potatoes and onions over the patties.
• Pour the gravy evenly over everything.

6. Bake Covered: Cover the dish with foil and bake for 1 hour.

7. Add Cheese and Finish Baking:

• Remove the foil.
• Sprinkle 1 cup shredded cheddar cheese over the top.
• Bake uncovered for an additional 15 minutes, until the cheese is melted and bubbly.

8. Serve: Let the dish rest for a few minutes, then serve and enjoy!
