Preheat oven to 400°F. Boil pasta until al dente, then drain.

2

Sauce noodles

Return noodles to the pot and add a jar of spaghetti sauce. Mix and let sit briefly.

Heat avocado oil in a pan over medium heat. Cook onion about 10 minutes until browned, then add garlic and cook about 1 minute.

In a bowl, mix cream cheese, sour cream, 1 tbsp Italian seasoning, and 2 cups mozzarella until combined.

Butter a 9×16 casserole dish. Add half the noodles, spread evenly, then add half the butter in small pieces. Add the rest of the noodles, then the meat sauce. Spread the cream cheese mixture over the meat and top with remaining mozzarella.
