01 - Bring a large pot of salted water to a rolling boil. Add bowtie pasta and cook according to package directions until al dente. Drain through a colander and set aside.
02 - While the pasta cooks, heat 1 tbsp olive oil in a large skillet over medium-high heat. Season diced chicken breasts with salt and black pepper, then add to the hot skillet. Cook for 7–8 minutes, turning occasionally, until golden brown and cooked through to an internal temperature of 165°F. Remove chicken from the skillet and set aside.
03 - Reduce the skillet heat to medium. Add the remaining 1 tbsp olive oil and all of the butter. Once the butter has melted completely, stir in the minced garlic and cook for about 1 minute until fragrant and lightly golden.
04 - Add Dijon mustard, hot sauce, smoked paprika, crushed red pepper flakes, chopped parsley, chives (if using), and fresh thyme leaves to the skillet. Stir thoroughly to combine all ingredients into a cohesive sauce.
05 - Stir in the lemon zest and fresh lemon juice, mixing well to incorporate. Taste the sauce and adjust salt and black pepper as needed.
06 - Return the seared chicken to the skillet, then add the drained bowtie pasta. Toss everything together vigorously until the chicken and pasta are evenly coated in the cowboy butter lemon sauce.
07 - Sprinkle grated Parmesan cheese over the top and toss once more to distribute. Serve immediately on warmed plates, garnished with additional fresh parsley if desired.
