1. Cook the bowtie pasta according to the package instructions. About 2-3 minutes before the pasta is done, add the broccoli florets to the boiling water. This will allow the broccoli to cook along with the pasta. Once the pasta and broccoli are tender, reserve 1/2 cup of the pasta cooking water, then drain the mixture and set it aside.

2. In a large bowl, toss the chicken pieces with the Cajun seasoning, garlic powder, smoked paprika, salt, and black pepper until evenly coated.

3. Heat the olive oil in a large skillet or sauté pan over medium-high heat. Add the seasoned chicken and cook for 5-7 minutes, stirring occasionally, until the chicken is golden brown and cooked through. Remove the chicken from the skillet and set it aside.

4. In the same skillet, melt the butter over medium heat. Add the minced garlic and crushed red pepper flakes (if using) and cook for 30 seconds, stirring constantly, until fragrant. Stir in the Dijon mustard, lemon juice, and lemon zest, combining everything well.

5. Return the cooked chicken to the skillet with the cowboy butter sauce. Add the cooked pasta and broccoli, tossing everything together and adding the reserved pasta water as needed to create a silky, well-coated sauce.

6. Stir in the grated Parmesan cheese, chopped parsley, and chives. Taste and adjust the seasoning as needed, adding more salt and pepper if desired.

7. Serve the Cowboy Butter Lemon Bowtie Chicken with Broccoli warm, garnished with extra Parmesan cheese if desired. Enjoy the bold, zesty flavors that will transport you straight to the heart of the American West!
