Ingredients
Method
- Brown ground beef with onion, bell pepper, garlic, Italian seasoning, salt, and pepper; drain fat.
- Cook macaroni in salted water until just al dente; drain well.
- Layer sauce, pasta, meat, and mozzarella in the slow cooker, repeating layers and ending with pepperoni on top.
- Cover and cook on low for 4 hours until cheese is melted and edges are bubbly.
- Let rest 5 minutes, then scoop onto plates and serve with red pepper flakes or fresh herbs.
Notes
This casserole tastes even better the next day, making it a great make-ahead meal. If you prefer a crisp pepperoni top, broil the finished casserole in an oven-safe dish for 2 to 3 minutes before serving.
