Cook pasta in salted boiling water according to package directions. Drain and set aside.
While pasta cooks, heat olive oil in a large skillet over medium heat. Add garlic and cook for 1 minute until fragrant.
Add shredded chicken and chicken broth. Let it warm through for 3–4 minutes.
Reduce heat and stir in ricotta, parmesan, salt, and pepper. Stir until the sauce is creamy and well combined.
Toss in cooked pasta and stir to coat evenly in the sauce.
Serve hot with a sprinkle of chopped herbs on top.
