Ingredients
  

1 lb ground beef (or turkey)

1/2 cup breadcrumbs

1/4 cup finely chopped onion

1/4 cup finely chopped bell pepper (red or green)

1 garlic clove, minced

1 egg, beaten

1 tsp Worcestershire sauce

1 tsp salt

1/2 tsp black pepper

1/2 tsp dried thyme

4 cups mashed potatoes (homemade or store-bought)

1 cup cheddar cheese, shredded

1 cup green beans, trimmed and cut into 1-inch pieces

1/2 cup beef broth (or chicken broth)

Fresh parsley, chopped (for garnish)

Instructions
 

Preheat Oven: Preheat your oven to 375°F (190°C).

    Prepare the Meat Mixture: In a large bowl, combine ground beef, breadcrumbs, chopped onion, bell pepper, minced garlic, beaten egg, Worcestershire sauce, salt, pepper, and thyme. Mix until well combined.

      Form the Meatloaf: Transfer the meat mixture into a greased 9x13 inch baking dish. Shape it into a loaf-like form or gently spread it evenly across the bottom of the dish.

        Add Green Beans: Scatter the cut green beans over the meat mixture, pressing them lightly into the meat.

          Layer the Mashed Potatoes: Spoon the mashed potatoes over the green beans and meat evenly. You can create grooves on the surface using a fork for extra texture, which will brown nicely while baking.

            Cheese It Up: Sprinkle the shredded cheddar cheese over the top of the mashed potatoes.

              Add Broth: Pour the beef broth around the edges of the casserole. This will keep the dish moist during baking.

                Bake: Cover the dish with aluminum foil and bake for 25 minutes. Then, remove the foil and bake for an additional 15-20 minutes or until the cheese is bubbly and the edges are slightly golden.

                  Garnish and Serve: Once done, let it sit for about 5 minutes before serving. Garnish with freshly chopped parsley for a pop of color.
