Season the chicken cutlets with smoked paprika and heat olive oil in a large skillet over medium-high heat for 1 minute.
Cook the chicken for 3 to 4 minutes per side until golden and cooked to 165°F / 74°C, then transfer to a plate.
Add butter and minced garlic to the same skillet and cook for 1 minute until fragrant.
Pour in chicken broth and lemon juice, scraping up any browned bits, and simmer for 2 minutes until slightly reduced.
Return the chicken to the skillet, spoon sauce over the top, sprinkle with parsley, and serve immediately.
