Fill a big pot with water, add salt, and bring to a boil. Cook your pasta just until firm. Drain completely, mix with a bit of olive oil to stop sticking. Put it in a big bowl for later.

Warm olive oil in a big pan over medium heat. Toss in Italian sausage and break it up as it cooks with a wooden spoon for about 5-7 minutes until it's no longer pink. Pour off any extra fat and set aside.

In a bowl, stir together the ricotta, egg, half of your mozzarella (1 cup), most of your Parmesan (1/2 cup), chopped basil, Italian herbs, and red pepper flakes if you want a kick. Add some salt and pepper to taste.

Put the cheese mixture into the bowl with pasta. Add the tomato sauce and cooked sausage too. Stir everything gently so you don't break the noodles.

Pour the whole mixture into your greased baking dish. Sprinkle the leftover cup of mozzarella and remaining 1/4 cup Parmesan on top.

Stick it in the hot oven for 25-30 minutes, until you see golden cheese and the pasta bubbling around the edges. Take it out and let it cool down for 5 minutes.

Scatter some fresh basil on top if you'd like, and serve it while it's warm.
