Spray your casserole dish with non stick spray.
Scoop about 2 tablespoons of sauce into each pan to line the bottom thinly. This helps keep noddles from sticking to the bottom and getting a wicked crispy bottom.
Depending on your brand of noodles you should be able to use 4 or 5 noodles per layer. I was able to use 5. So I lay three, then place two more on top.
Toss a bit of mozzarella cheese on top of the noodles (trust me!)
Spoon 1/4 of the sauce over that layer. Spread evenly
Toss one fourth of the parmesan cheese over top. (trust me!)
Toss about 1/4 of the cheese over top.
Lay another layer of noodles.
Then another thin toss of mozzarella cheese. (trust me!)
Then another layer of sauce.
Then toss on one fourth of the amount of parmesan cheese (trust me!)
Another layer of mozzarella.
Now repeat with second casserole dish, or if you're like me you can layer them at the same time so you can divide evenly.
Now place in the preheated oven.
Cook uncovered for about 15 to 20 minutes, depending on how golden brown you want the top. It's a good idea to start checking at 10 minutes since every oven is different and all cheeses vary depending on moisture content.
Remove from oven.
Grab a spatula and wish for a clean slice.
Serve with a big old "my tummy hurts, but in a good way| smile!
