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 crispiness.
Mix your seasoning: In a small bowl, combine ranch seasoning, smoked paprika, garlic powder, onion powder, black pepper, and salt.
Season the chicken: Rub olive oil all over the thighs. Sprinkle the seasoning mix evenly on both sides, focusing extra on the skin.
Sear for crisp skin: Heat a large oven-safe skillet over medium-high. Place thighs skin-side down and cook undisturbed for 4–5 minutes, until the skin is golden and beginning to crisp.
Flip.
Roast to finish: Transfer the skillet to the oven and roast for 18–22 minutes, until the internal temperature hits 165°F (74°C) at the thickest part without touching bone.
Add the “loaded” topping: Remove the skillet, sprinkle the cheddar evenly over the thighs, and scatter the crumbled bacon on top.
Broil to melt: Switch the oven to broil. Broil the chicken for 1–2 minutes, just until the cheese is melted and bubbly. Watch closely to avoid burning.
Rest briefly: Let the chicken rest 5 minutes so the juices settle and the cheese sets slightly.
Finish and serve: Top with green onions and a few dollops or drizzles of sour cream.
Add parsley and a squeeze of lemon if you like. Serve hot.
