- 1 (16 ounce) box pasta I used Rigatoni
- 1 (6 ounce) pepperoni Leave about 12 pepperoni out to top the casserole.
- 1 green pepper chopped
- 1/2 cup diced onion
- 1 cup diced mushrooms
- 1 (2.25 oz can) sliced black olives Leave a few to top the casserole. 
- 2 cups shredded mozzarella cheese
- 1 lb Italian sausage
- 1 teaspoon Italian seasoning
- 1 24 oz jar marinara sauce
- Preheat the oven to 350 degrees. Spray a 9 x 13 casserole dish with non-stick cooking spray.  
- Cook pasta according to directions on box. 
- Cook Italian sausage in a skillet over medium high heat. Cook until browned. Use a wooden spoon to crumble sausage while cooking. 
- Drain excess fat. 
- Stir the diced onions, mushrooms, and bell peppers in with the sausage. Cook another 2-3 minutes.  
- Add in the black olives, pepperoni, and sauce.  
- Drain the cooked pasta and stir the pasta in with the sausage mixture.  
- Place pasta mixture in the prepared 9x13 casserole dish. Top with the shredded cheese and additional pepperoni, black olives, and green peppers.  
- Bake for about 25 minutes or until the cheese melts and the casserole is heated through. 
- Cook the pasta al dente. The pasta will keep cooking in the oven so you will want to boil them to al dente so they don't become mushy.
- Meal prep. If you know you are going to make this meal, pre-chop the veggies and pre-cook your sausage. When you are ready to assemble, everything will be ready to mix together.
- Salt you pasta water while cooking the pasta. It is a great way to season the pasta itself.
- Remove any excess grease. Once the sausage cooks, make sure to remove any excess grease.
