Preheat your oven to 375°F. Peel and thinly slice 2 lbs Russet potatoes. For best results and even cooking, aim for uniform 1/8-inch slices. This initial prep is key for a smooth assembly of your Cheesy Ground Beef and Potato Casserole.

In a large skillet, brown 1.5 lbs 80/20 ground beef over medium-high heat. Drain any excess fat. Add 1 large yellow onion, chopped, and cook until softened, about 5 minutes. Stir in 3 cloves garlic, minced, and cook for 1 minute more until fragrant.

Sprinkle 2 tbsp all-purpose flour over the beef mixture, stirring for 1 minute. Gradually whisk in 1.5 cups beef broth and 1/2 cup whole milk. Stir in 1/2 cup sour cream, 1 tbsp Worcestershire sauce, 1 tsp smoked paprika, 1/2 tsp garlic powder, 1/2 tsp onion powder, 1 tsp salt, and 1/2 tsp black pepper. Bring to a gentle simmer.

Lightly grease a 9x13 inch baking dish. Arrange half of the thinly sliced Russet potatoes in an even layer. Spoon half of the savory ground beef mixture over the potatoes. Sprinkle with 1 cup sharp cheddar cheese, shredded, and 1/2 cup Monterey Jack cheese, shredded. Repeat these layers once more.

Cover the baking dish tightly with aluminum foil. Bake for 25 minutes. This initial covered bake ensures the potatoes in your Cheesy Ground Beef and Potato Casserole become tender and absorb the rich, savory flavors from the sauce.

Remove the foil. Sprinkle the remaining 1 cup sharp cheddar cheese, shredded, and 1/2 cup Monterey Jack cheese, shredded, evenly over the top. Return the dish to the oven, uncovered, and bake for another 10-15 minutes, or until the cheese is bubbly and golden brown.

Let the Cheesy Ground Beef and Potato Casserole rest for 5-10 minutes before serving. This allows the layers to set and makes for easier portioning. Garnish with 2 tbsp fresh parsley, chopped, for a vibrant finish.
