Creating this Lemon Garlic Butter Chicken and Green Beans Skillet is simple if you follow these straightforward steps:

1. Prep the Ingredients: Begin by washing and trimming the green beans. Mince the garlic and zest the lemon.

2. Cook the Chicken: In a large skillet, melt 2 tablespoons of butter over medium heat. Season the chicken breasts with salt and pepper, then add them to the skillet. Cook for 6-7 minutes per side or until golden brown and cooked through.

3. Remove Chicken: Once the chicken is cooked, remove it from the skillet and place it on a plate. Cover it loosely with aluminum foil to keep warm.

4. Saute Green Beans: In the same skillet, add the remaining 2 tablespoons of butter. Once melted, add the trimmed green beans and cook for about 5 minutes, stirring occasionally, until they are bright green and tender.

5. Add Garlic: Stir in the minced garlic, lemon juice, and red pepper flakes (if using). Cook for an additional 1-2 minutes, just until the garlic becomes aromatic and slightly golden.

6. Combine Chicken and Beans: Return the chicken breasts to the skillet, along with any juices from the plate. Add lemon zest and stir everything together, allowing the flavors to meld for a minute.

7. Garnish and Serve: Remove the skillet from heat and sprinkle with chopped parsley before serving. Enjoy this delicious dish straight from the pan!
