Creating Cowboy Butter Chicken Linguine is quite straightforward with these easy-to-follow steps:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add the linguine and cook according to package instructions until al dente. Reserve ½ cup of pasta water and then drain the linguine.
2. Sauté the Chicken: In a large skillet over medium heat, melt ¼ cup of butter. Add diced chicken and season with salt and pepper. Cook for about 5-7 minutes, or until the chicken is golden brown and cooked through.
3. Add Garlic: Add the minced garlic and red pepper flakes to the skillet with the chicken. Sauté for another minute until fragrant.
4. Create the Sauce: Pour in the chicken broth and lemon juice. Stir well, allowing the mixture to come to a gentle simmer.
5. Incorporate the Remaining Butter: Reduce the heat to low. Add the remaining ¼ cup of butter to the skillet, stirring until melted and fully combined into the sauce.
6. Combine Pasta and Sauce: Add the drained linguine to the skillet. Toss well to coat in the buttery sauce. If the mixture seems dry, add a bit of the reserved pasta water until desired consistency is reached.
7. Finalize the Dish: Stir in the oregano. Taste and adjust seasoning if needed, with more salt or pepper if desired.
8. Garnish and Serve: Remove from heat. Plate the linguine, top with chopped parsley and freshly grated Parmesan cheese.
