This creamy and cheesy pasta casserole is packed with classic Philly cheesesteak flavors, all made easy in the crockpot for a comforting, low-effort meal.
In a skillet over medium heat, cook ground beef, diced onion, green and red bell peppers, and minced garlic until the beef is browned and vegetables are tender. Drain excess fat.
Transfer the mixture to a crockpot. Add uncooked pasta, beef broth, milk, French onion soup mix, Worcestershire sauce, and black pepper. Stir to combine.
Cover and cook on low for 3–4 hours or until pasta is tender.
Stir in provolone and mozzarella cheese until melted and combined. Serve warm.
Notes
You can customize the cheese or seasonings to your preference. This dish reheats well too!
