Cook pasta in boiling salted water for 8-10 minutes until al dente, then drain and set aside.
Season chicken with garlic powder, onion powder, salt, and pepper. Cook in olive oil for 6-7 minutes per side until golden brown. Let rest, then slice.
Melt butter in the same skillet, then add heavy cream. Simmer for 2-3 minutes until thickened.
Stir in mozzarella and Parmesan cheese until melted and smooth.
Add cooked pasta to the skillet, tossing to coat with the cheesy sauce.
Combine cooked chicken with pasta and sauce, then garnish with parsley and serve hot.
Notes
For a quicker meal, use leftover or rotisserie chicken and pre-shredded cheeses.
