Bring a large pot of salted water to a boil. Add pasta and cook according to package instructions until al dente, reserving ½ cup pasta water before draining.

Cut chicken into bite-sized pieces, season with paprika, Italian seasoning, salt, and pepper. Heat olive oil and butter in a skillet, add chicken, and sauté until cooked through, about 6-8 minutes.

Add minced garlic to the skillet and sauté for 1-2 minutes until fragrant.

Reduce heat, add more butter, then heavy cream to the skillet. Stir in Parmesan cheese gradually until smooth and creamy, about 3-4 minutes.

Combine cooked pasta with the creamy sauce, and add garlic butter chicken on top. Serve hot, garnished with additional Parmesan or herbs.
