  • 1 Bell Pepper (any color), chopped
  • 2-3 cloves Garlic, minced
  • 24-32 oz jar Marinara Sauce
  • 14.5 oz can Diced Tomatoes, undrained

Instructions
 

Cooking Steps

  • Brown the ground beef or sausage in a large skillet over medium heat, draining excess fat once no longer pink.
  • Add chopped onion and bell pepper to the skillet, cooking until softened, then stir in minced garlic and Italian seasoning for one minute until fragrant.
  • Stir marinara sauce and diced tomatoes into the meat mixture in the skillet, and let it simmer for 5 minutes.
  • Lightly grease a 6-quart or larger slow cooker, then layer with a third of the cooked pasta, meat sauce, mozzarella, Parmesan, and pepperoni slices.
  • Continue layering pasta, sauce, cheeses, and pepperoni, ending with generous amounts of mozzarella and pepperoni.
  • Cover and cook on low for 3-4 hours or high for 2-2.5 hours until pasta is tender and cheese is bubbly and melted.
  • Serve generous portions of the delicious pizza casserole.

Notes

For extra flavor, consider adding a pinch of red pepper flakes to the meat mixture. This casserole is perfect for meal prepping and reheats well throughout the week. If you prefer a crispier topping, you can transfer the casserole to an oven-safe dish and broil for a few minutes after slow cooking.
