In a large skillet, melt 2 tablespoons of butter over medium-high heat. Add the uniformly cut chicken breast pieces, seasoning them generously with Cajun spices. Sauté for 6-7 minutes, stirring occasionally, until the chicken is golden brown and cooked through, reaching an internal temperature of 165°F. Once done, remove the chicken from the skillet and set it aside to keep warm.

In a large pot of boiling salted water, cook the bowtie pasta according to the package instructions, usually about 8-10 minutes until al dente. Before draining, reserve about 1 cup of the pasta water to adjust the sauce later. Once cooked, drain the pasta and set it aside while retaining that flavorful water for the Cowboy Butter Lemon sauce.

In the same pot used for the pasta, add the remaining tablespoon of butter and bring it to medium heat. Add the broccoli florets and sauté for 3-4 minutes, stirring frequently until they turn bright green and tender-crisp. Once cooked, drain any excess water, then add the broccoli to the skillet with the chicken, mixing everything gently to combine.

In the skillet over medium heat, melt the last teaspoon of butter. Add the minced garlic, sautéing it for about 30 seconds until fragrant, being careful not to burn it. Stir in the fresh lemon juice, chopped herbs, and a pinch of red pepper flakes for that added kick. If you prefer a richer sauce, add a splash of cream now; otherwise, it's ready to combine.

Add the cooked pasta, sautéed chicken, and broccoli into the skillet with the sauce. Toss everything gently until well-coated. If the sauce seems too thick, gradually add reserved pasta water, mixing until you reach your desired consistency. Let it simmer for a couple of minutes, allowing the flavors to meld together beautifully.

Once everything is nicely blended and heated through, remove the skillet from the heat. Serve the Cowboy Butter Lemon Bowtie Chicken with Broccoli hot, garnished with extra herbs and a sprinkle of Parmesan cheese, if desired. This comforting weeknight meal is ready to delight your family and friends!
