Prep the chicken: Pat the chicken thighs very dry with paper towels.
Dry skin is key to crispiness. Season both sides with ranch seasoning, smoked paprika, garlic powder (if using), and black pepper.
Start the bacon: Place a large oven-safe skillet (cast iron is great) over medium heat. Add the chopped bacon and cook until the fat renders and the bacon is just crisp, about 6–8 minutes.
Use a slotted spoon to transfer bacon to a plate, leaving about 2 tablespoons of fat in the pan. If there’s more, carefully spoon some out; if there’s less, add a little olive oil.
Sear the chicken: Increase heat to medium-high. Place the chicken thighs skin-side down in the hot fat.
Don’t crowd the pan; work in batches if needed. Sear until the skin is deeply golden and crisp, about 6–8 minutes. Flip and cook 2 minutes on the second side.
Finish in the oven: Preheat the oven to 400°F (200°C) if you haven’t already.
Sprinkle the crisped bacon around the chicken. Transfer the skillet to the oven and roast until the chicken reaches 165°F (74°C) at the thickest part, about 15–20 minutes depending on size.
Optional butter baste: Remove from the oven and dot a little butter around the pan. Tilt and spoon the buttery, bacon-y juices over the chicken once or twice for extra gloss and richness.
Rest and garnish: Let the chicken rest 5 minutes.
Scatter with parsley or chives. Serve with lemon wedges to squeeze over the top—it balances the savory flavors beautifully.
