Preheat the oven to 400 degrees F / 200 degrees C.
If you don’t have cooked pasta in hand, cook pasta for about 5-6 minutes and allow to drain completely. Don’t rinse with cold water.
Grease a 9x13 inch baking dish with oil. Add a third of a cup of the marinara sauce at the bottom.
Add all the pasta in the baking dish. Sprinkle the top of the cheddar cheese.
Arrange all the frozen meatballs on the cheese. Add half of the marinara sauce, the italian seasoning, half of the mozzarella cheese and half of the parmesan cheese. Repeat again with the marinara sauce and the cheese.
Place in the middle of the oven and bake for 25 minutes.
Remove and let it sit for 5 minutes before serving.

Notes
If using fresh meatballs, make sure your pasta is fully cooked before assembling the casserole. The cook time can be reduced since the meatballs aren’t frozen.
For a golden and bubbly top, broil the casserole for a few minutes at the end of the baking time.
Allow the casserole to rest for a few minutes before serving. This helps the flavors meld, and it makes it easier to cut and serve.
Add fresh herbs like basil or parsley just before serving for a burst of fresh flavor. This adds a nice contrast to the baked casserole.
Storage - keep tightly covered or in an airtight container inside the fridge for up to 5 days.
