    • 2 cloves garlic, minced
    • 1 teaspoon Italian seasoning
    • 1/2 teaspoon salt
    • 1/4 teaspoon black pepper

    • 2 tablespoons all-purpose flour
    • 2 cups milk
    • 2 cups shredded cheddar cheese, divided
    • 1/4 teaspoon salt
    • 1/8 teaspoon black pepper

Step-by-Step Instructions for Making the Recipe

  1. Start the Beef: Brown the ground beef in a large skillet over medium-high heat. Drain off any excess grease.
  2. Add Aromatics: Stir in the chopped onion and minced garlic. Cook until the onion is softened, about 5 minutes.
  3. Season and Simmer: Add the Italian seasoning, salt, and pepper. Pour in the diced tomatoes and simmer for 5-10 minutes, allowing the flavors to meld.
  4. Cook the Potatoes: While the beef is simmering, boil the cubed potatoes in salted water until tender, about 15-20 minutes.
  5. Mash the Potatoes: Drain the potatoes well and return them to the pot. Add the milk, melted butter, salt, and pepper. Mash until smooth and creamy.
  6. Make the Cheese Sauce: In a saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 minute. Gradually whisk in the milk until smooth.
  7. Cheese It Up: Bring to a simmer, stirring constantly, until the sauce thickens. Remove from heat and stir in 1 1/2 cups of the shredded cheddar cheese, salt, and pepper until melted and smooth.
  8. Assemble the Casserole: Preheat oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
  9. Layer the Ingredients: Spread the ground beef mixture evenly in the bottom of the dish. Top with the mashed potatoes, spreading them into an even layer.
  10. Pour the Cheese Sauce: Pour the cheesy sauce evenly over the potato layer.
  11. Add the Final Cheese: Sprinkle the remaining 1/2 cup of cheddar cheese over the top.
  12. Bake: Bake for 20-25 minutes, or until the casserole is bubbly and the cheese is melted and golden brown.
  13. Serve: Let the casserole cool slightly before serving. Enjoy your Cheesy Ground Beef Potato Casserole!
