Prep the chicken: Pat the chicken thighs very dry with paper towels.
Dry skin means better browning and crispier results.
Season generously: In a small bowl, mix salt, pepper, smoked paprika, garlic powder, and onion powder. Rub the mixture all over the chicken, especially under any loose skin.
Heat the pan: Set a large skillet (cast iron works great) over medium-high heat. Add the olive oil and heat until shimmering.
Sear the thighs: Place chicken thighs skin-side down.
Don’t crowd the pan; work in batches if needed. Cook without moving for 6–8 minutes, until the skin is deeply golden and crisp.
Flip and render: Turn the thighs and cook the other side for 4–6 minutes. Transfer to a plate.
They won’t be fully cooked yet—this is okay.
Make the garlic butter base: Lower heat to medium. Add the butter to the pan. Once melted, stir in the minced garlic and red pepper flakes.
Cook for 30–60 seconds until fragrant, not browned.
Deglaze and brighten: Pour in the chicken broth and lemon juice. Scrape up brown bits from the bottom of the pan with a wooden spoon. That’s flavor you don’t want to lose.
Return the chicken: Nestle the thighs back into the sauce, skin-side up.
Spoon some sauce over the top without soaking the skin, so it stays crisp.
Finish cooking: Reduce heat to medium-low, cover, and cook for 8–12 minutes, or until the internal temperature reaches 175–185°F. Dark meat is best when cooked a bit higher—it turns silky and tender.
Uncover and reduce: Remove the lid for the last 2–3 minutes to let the sauce thicken slightly. Taste and adjust salt and lemon as needed.
Garnish and serve: Sprinkle with chopped parsley.
Serve with sautéed greens, roasted broccoli, or cauliflower mash to keep it low carb.
