Sloppy Joe Mac And Cheese

Step 1
Bring a large pot of lightly salted water to a boil. Place macaroni in the pot, and cook for 8 to 10 minutes or until al dente; drain.

Step 2
Preheat oven to 375 degrees F (190 degrees C). Lightly grease a large casserole dish.

Step 3
Place the ground beef in a skillet over medium heat, and cook until evenly brown. Drain grease. Mix in diced tomatoes, tomato paste, and sloppy joe seasoning. Reduce heat to low, and simmer 10 minutes.

Step 4
Melt the butter in a large pot over medium-high heat. Stir in the onion, and cook until tender. Mix in flour, mustard, salt, and pepper. In a bowl, mix the half and half and Worcestershire sauce. Gradually whisk half and half mixture into the pot. Bring to a boil, and cook 1 minute, until slightly thickened. Remove from heat. Mix in 3 cups of cheese. Stir cooked pasta into the pot, evenly coating with the sauce. Transfer to the casserole dish. Layer with the beef mixture and top with remaining cheese.

Step 5
Cover, and bake 30 minutes in the preheated oven. Remove cover, and continue baking 10 minutes, until bubbly.
