Johnny Marzetti Casserole - Slow Cooker or Oven!

Step 1

If making in the oven, preheat your oven to 350 °F.

Step 2

Cook the pasta according to the package directions to a firm al dente. Remember, you are cooking it even further in the oven or crockpot, you don't want mush.

Step 3

Fry the ground beef and Italian sausage in a large skillet until browned. Mix in the onion and mushrooms and cook until soft. Add in the garlic, saute for 2-3 minutes.

Step 4

Stir in the Italian seasoning, diced tomatoes and tomato sauce. Simmer briefly, then set aside and cool for 10 minutes.

Step 5

Grease or spray a 9x13 casserole dish or the inside of the slow cooker. Spread a little bit of the sauce on the bottom of the dish/slow cooker, then top with the pasta.

Step 6

Sprinkle the Italian blend cheese over the pasta, then pour the remaining sauce over the casserole.

Step 7

Cover and cook in the oven for 45 minutes or in the slow cooker on low for 1 1/2 - 2 hours. When ready, uncover, sprinkle the cheddar cheese on top and then cover again until melted.

Step 8

Serve and enjoy!
