In a large mixing bowl, combine olive oil, minced garlic, smoked paprika, crushed red pepper flakes, and a pinch of salt and black pepper. Add the chicken thighs, coating them well in the marinade. Cover and let marinate in the refrigerator for at least 30 minutes (or up to overnight for maximum flavor).
While the chicken is marinating, bring a pot of salted water to a boil. Add the broccoli florets and blanch them for 2-3 minutes until bright green and slightly tender. Drain and immediately plunge into an ice bath to stop the cooking process. Set aside.
In a large skillet over medium-high heat, melt the unsalted butter. Once melted, add the marinated chicken thighs to the skillet. Cook for about 5-7 minutes per side, or until the chicken is golden brown and cooked through (internal temperature should reach 165°F).
Once the chicken is cooked, stir in the fresh rosemary and thyme. Squeeze the juice of one lemon into the skillet for an extra burst of flavor.
Add the blanched broccoli to the skillet, gently tossing it with the chicken and herb butter mixture to coat evenly. Cook for an additional 2-3 minutes until the broccoli is heated through.
Plate the chicken and broccoli mixture, drizzling any remaining herb butter from the skillet over the top. Garnish with lemon slices and additional fresh herbs if desired.
Notes
Adjust red pepper flakes to taste for desired spiciness.
