You can’t go wrong with this hearty, flavorful Cheeseburger Casserole! It's easy to make in one pot with ground beef, macaroni, and plenty of cheese, all cooked together to perfection. A quick and easy dinner option that’s a favorite with both kids and adults!
Heat a large-rimmed skillet over medium heat. Add the 1 pound lean ground beef and cook until no longer pink, mincing it with a wooden spoon. Stir in the 1 medium onion (chopped), 3-4 garlic cloves (minced), and 1 tablespoon Worcestershire sauce of . Cook for 6-8 minutes more, stirring occasionally.
Add the 1/2 cup ketchup, 1/2 cup mayonnaise, 2 tablespoons Dijon mustard, and 4 cups beef broth, stir well, and bring to a boil. Once the sauce is bubbling, add the 16 ounces elbow macaroni and reduce the heat to a simmer. Cook the macaroni into the sauce, stirring frequently through the bottom of the pan to avoid it from burning. The pasta can easily catch the bottom of the pan if left unsupervised.
Simmer the pasta for about 12-14 minutes, adding the remaining cup of broth when the liquid is mostly absorbed by the pasta. Once the pasta is cooked to al-dente, taste and season with Kosher salt and pepper if needed.
Sprinkle the 1 1/2 cups shredded cheddar cheese and cover the pot. Continue to cook over low heat for a couple of minutes more, just until the cheese is melted and bubbly. Garnish with chopped parsley, if desired, and serve immediately while hot.
