If you prefer a golden, bubbly topping, preheat the oven to broil and position the rack in the center.
Heat olive oil in a large Dutch oven or deep skillet over medium-high heat.
Add the diced onion and ground beef. Break the beef into small crumbles while cooking.
Season with granulated garlic, 1 teaspoon kosher salt, and 1/4 teaspoon black pepper. Cook for 6–7 minutes until the beef is browned and the onion becomes tender.
Stir in the tomato paste and halal Worcestershire sauce. Cook for 1 minute until the tomato paste darkens slightly.
Pour in 3¼ cups beef broth, diced tomatoes with their juices, the remaining salt, and remaining pepper. Bring everything to a boil.
Add the elbow macaroni and cook over medium heat for about 10 minutes, stirring occasionally. Add extra broth a little at a time if the pasta absorbs the liquid too quickly.
Remove from the heat and stir in 1½ cups shredded cheddar until fully melted.
Taste and adjust seasoning if needed.
Sprinkle the remaining cheese over the top.
Cover for about 3 minutes until melted, or broil for 2–3 minutes for a beautifully browned finish.
Garnish with parsley or scallions and serve your delicious Cheeseburger Casserole Recipe warm.
