Preheat oven to 350 degrees. Bring a large pot of water to boil and season water generously with salt. Add spaghetti noodles and cook until al dente. Drain the pasta and mix in a little olive oil to prevent pasta from sticking.

In a large skillet over medium-high heat, add ground beef and diced onions. Brown the meat until no pink is visible then soak up any excess grease using a paper towel. Season with Italian seasoning, onion powder, garlic powder, salt and pepper. Mix until combined then set aside a small amount of meat for the topping.

Add the jar of pizza sauce, pasta sauce, cooked pasta, 1 cup of bacon and 20 pepperoni slices then mix until well combined. Pour pasta mixture into a 9x13 baking dish and sprinkle mozzarella and parmesan cheese on top. Then sprinkle the ground beef you set aside on top and place 10 pepperoni slices on top as well.

Bake at 350 degrees for 20-25 minutes or until the cheese is melted and the casserole is bubbly. Allow to cool for 10 minutes then serve and enjoy!
