In a nonstick pan over medium heat, cook the ground beef until it’s no longer pink, about 7-10 minutes. Drain and add to the crockpot.
Add the onion, garlic, water, bouillon cubes, crushed tomatoes, diced tomatoes, Worcestershire sauce, bay leaves, Italian seasoning, and salt. Stir well.
Cover and cook on low for 4-5 hours or on high for 2 hours.
30 minutes prior to serving, stir in the macaroni. Cover and cook just until the noodles are tender.
Remove the bay leaves and stir in the cheddar cheese.
Serve immediately so that the pasta does not turn mushy.
