If you are using chicken cutlets, skip this step and go to step #2. Slice the chicken breasts in half lengthwise. Place the chicken in between two sheets of plastic wrap and use a meat mallet to pound the thicker sides until they’re an even thickness.
1 pound boneless skinless chicken breasts
In a shallow bowl, whisk together the flour, salt, and pepper. Coat each piece of chicken in the flour mixture, shaking off any excess.
1 cup all-purpose flour, ½ teaspoon salt, ¼ teaspoon ground black pepper
Heat olive oil and butter in a large skillet over medium heat. Add the chicken and cook for 3-4 minutes on each side, or until golden brown. If necessary, cook in batches. Remove the chicken and set aside.
2 tablespoons olive oil, 2 tablespoons unsalted butter
Using the same skillet, sauté the minced garlic for about 30 seconds, until fragrant. Add the white wine (or chicken broth), lemon juice, and lemon slices. Simmer for 5 minutes, allowing the sauce to thicken.
3 garlic cloves, 1 ½ cups dry white wine, 2 lemons, 3 to 4 lemon slices
Stir in the capers and cook for another 2-3 minutes until the sauce reaches your desired consistency.
2 to 3 tablespoons capers
Return the chicken to the skillet and coat with the sauce. Serve over pasta, rice, or potatoes, and garnish with freshly chopped parsley if desired.
