Season: Pat the chicken dry (this is key for a good sear). Mix all spices in a small bowl and rub generously over all sides of the chicken.
Sear: Heat olive oil in a large skillet over medium-high heat. Add the chicken and cook for 6–7 minutes per side. Ensure the internal temperature reaches 165°F (74°C). Remove the chicken and tent it loosely with foil to rest.
Deglaze: Reduce heat to medium. Melt the butter in the same skillet and sauté the garlic for about 30–60 seconds.
Simmer: Pour in the chicken broth, smoked paprika, and lemon juice. Use a wooden spoon to scrape up the browned bits from the bottom of the pan. Let it simmer for 2–3 minutes until it thickens slightly.
Finish: Season the sauce with salt and pepper, then pour it over the rested chicken breasts.
Serve: Slice and serve immediately.
