Season the Chicken:In a bowl, toss chicken pieces with paprika, garlic powder, onion powder, salt, pepper, and red pepper flakes.
Sear the Chicken:In a large skillet, heat butter and olive oil over medium-high heat. Add the seasoned chicken and cook until golden and cooked through, about 6-8 minutes. Remove from skillet and set aside.
Make the Cowboy Butter Sauce:In the same skillet, lower heat to medium. Add minced garlic and cook for 1 minute until fragrant. Stir in lemon juice, Dijon mustard, parsley, thyme, and cayenne pepper. Cook for another 1-2 minutes.
Cream It Up:Pour in the heavy cream and Parmesan cheese. Stir until smooth and creamy, about 2-3 minutes.
Combine Pasta & Chicken:Return cooked chicken to the skillet, then toss in the cooked pasta. Mix well until everything is coated in the cowboy butter sauce.
Serve:Garnish with more parsley or chives if desired, and serve hot!
