This Garlic Cowboy Butter Chicken is a rich, buttery, one-pan dinner featuring juicy pan-seared chicken breasts coated in a bold garlic butter sauce with Dijon mustard, lemon juice, herbs, and spices. Ready in just 30 minutes, it's an easy weeknight meal that tastes like it came from a restaurant.
In a small bowl, mix the salt, black pepper, smoked paprika, garlic powder, and onion powder.
Rub the seasoning mixture evenly over both sides of each chicken breast.
Heat the olive oil in a large skillet over medium-high heat.
Add the chicken breasts and cook for 5-6 minutes without moving them until golden brown.
Flip the chicken and cook for another 5-6 minutes.
Transfer the chicken to a plate. Reduce the heat to medium.
Add the butter to the skillet and let it melt.
Stir in the minced garlic and cook for about 30 seconds until fragrant.
Add the Dijon mustard, Worcestershire sauce, lemon juice, Italian seasoning, smoked paprika, and crushed red pepper flakes. Stir well until the sauce is smooth and combined.
Return the chicken to the skillet, and spoon the butter sauce over each chicken breast.
Simmer for 5-8 minutes or until the chicken reaches an internal temperature of 165°F (74°C).
Sprinkle with the chopped parsley, and let the chicken rest for 5 minutes before slicing.
Serve warm with the buttery pan sauce spooned over the top.
