Cheesy spaghetti squash casserole

This casserole is super easy and yummy. It has lots of cheese, so probably not something I will make every week. Or maybe I would make it with less cheese, and I bet it would still be good. Here's my version of the recipe:
spaghetti squash cooked (cut in half, scoop out seeds, put on a plate face down in microwave for 14 minutes. Drain in a colander while the rest is cooking.)
sweet onion
2 cloves garlic
coconut oil
ground turkey
1 jar clean pasta sauce
1 egg
half cup part skim ricotta
half cup grated mozzarella
half cup parmesan

Preheat oven to 350 degrees. Chop onion and sauté with garlic and oil in large pan until translucent. Add ground turkey and brown. Add sauce and squash. Mix eggs and cheese (not parmesan), then add to turkey and squash mixture. Pour into large casserole dish and bake for 20 minutes. Add parmesan cheese to top then bake for about 12 minutes more until cheese melts and starts to brown.
