Preheat and prep: Heat your oven to 425°F (220°C). Pat the chicken thighs very dry with paper towels. Dry skin is key to crispy results.
Season generously: In a small bowl, mix salt, pepper, paprika, garlic powder, and onion powder.
Rub the seasoning all over the thighs, lifting the skin to season underneath if possible.
Heat the pan: Place a large oven-safe skillet (cast iron is ideal) over medium-high heat. Add the oil and let it get hot until it shimmers.
Sear skin-side down: Lay the thighs skin-side down and don’t move them for 6–8 minutes. You’re aiming for deep golden, crisp skin.
Work in batches if needed to avoid crowding.
Flip and finish sear: Flip the thighs and cook the flesh side for 2 minutes. This step starts the cooking process before the oven finish.
Make the garlic butter: In a small saucepan or the microwave, melt the butter with minced garlic, thyme, and rosemary. Heat just until fragrant, 30–60 seconds.
Stir in the lemon juice.
Baste and bake: Spoon half the garlic butter over the chicken. Transfer the skillet to the oven and bake 15–20 minutes, until the thickest part reaches 165°F (74°C).
Baste again and rest: Remove from the oven and brush with the remaining garlic butter. Let the chicken rest 5 minutes so the juices settle.
Garnish and serve: Sprinkle with fresh parsley.
Serve with lemon wedges and your favorite low-carb sides like roasted broccoli, sautéed zucchini, or a crisp salad.
