In a shallow dish, combine flour, salt, pepper, and garlic powder.
Dredge each chicken cutlet in the flour mixture, shaking off any excess.
Heat olive oil and 1 tablespoon of butter in a large skillet over medium-high heat.
Add chicken cutlets to the skillet and sear for 3 to 4 minutes per side until golden brown and the internal temperature reaches 165°F (74°C).
Transfer the cooked chicken to a plate and tent loosely with foil.
Reduce skillet heat to medium and add the remaining 3 tablespoons of butter.
Add the minced garlic to the melted butter and sauté for 60 seconds until fragrant.
Pour in the chicken broth, scraping the bottom of the pan to release the fond. Simmer for 2 minutes until the liquid reduces slightly.
Whisk in the lemon juice and chopped parsley.
Return the chicken to the skillet, spooning the garlic butter sauce over the cutlets to glaze before serving.
