1. Prepare the Chicken: Place chicken breasts between plastic wrap and pound to ½ inch thick for even cooking.
2. Dredge in Flour: Lightly coat each chicken breast in flour, shaking off excess.
3. Sauté the Chicken: In a skillet over medium-high heat, melt 2 tablespoons of butter. Cook chicken for about 3-4 minutes per side until golden brown and cooked through. Remove from skillet and keep warm.
4. Make the Sauce: In the same skillet, add garlic and sauté for about 30 seconds. Pour in chicken broth and bring to a simmer; stir in lemon juice and capers.
5. Combine and Serve: Return chicken to the skillet, coating with sauce for about a minute on low heat.
6. Finishing Touches: Plate the dish, garnishing with fresh parsley if desired.
