Meanwhile, sprinkle both sides of chicken evenly with garlic powder, salt and pepper. Dredge chicken in flour in a shallow dish; shake off excess. Set the chicken on a plate and repeat with remaining chicken.
1 tsp. salt, 1 1/2 lb. chicken cutlets (about 5-7 cutlets)*, 1 tsp. garlic powder, 1/2 tsp. pepper, 1/3 cup All-Purpose Flour*
Heat 2 Tbsp. butter and 1 Tbsp. olive oil in a frying pan over medium high heat.
4 Tbsp. butter, divided, 2 Tbsp. olive oil, divided
Once hot, place chicken cutlets in pan (do not crowd the pan) and brown on each side, about 3 minutes per side. Remove the chicken from the pan and set on a new plate. (Chicken will not be fully cooked yet, that's OK)
Turn the heat to medium-low and to the same pan, add in the capers, lemon juice, white wine, and garlic. Whisk in remaining 2 Tbsp. butter. Use a spatula to scrape up the browned bits if needed. Bring the sauce to a simmer and then thicken by adding in a cornstarch slurry: 1 Tbsp. cornstarch mixed with 1 Tbsp. water. While the sauce is simmering, mix the water and cornstarch together in a small dish and whisk into the sauce. Continue to whisk, the sauce will begin to thicken.
2 large fresh lemons, squeezed (about 1/3 cup), 3 Tbsp. capers, 1/2 cup white wine (or chicken broth), 2 cloves garlic
Place the chicken back into the pan, spoon some of the sauce over the chicken. Place a lid on the pan and turn heat to low. Let cook for 10-15 minutes or until chicken reaches an internal temperature of 165°F.
