Preheat the oven: Set to 425°F (220°C). A hot oven ensures crispy skin and juicy meat.
Pat the chicken dry: Use paper towels to remove moisture from the thighs. Dry skin equals better browning and crispiness.
Make the marinade: In a bowl, combine 3 tablespoons olive oil, minced garlic, lemon zest, 1 tablespoon lemon juice, 1 teaspoon dried oregano, 1 teaspoon dried basil, 1/2 teaspoon dried rosemary (crushed), 1/2 teaspoon red pepper flakes (optional), 1 teaspoon kosher salt, and 1/2 teaspoon black pepper.
Coat the chicken: Add the thighs to the bowl and toss thoroughly.
Make sure seasoning gets under the skin for more flavor.
Arrange in the pan: Place thighs skin-side up on a rimmed baking sheet or in a large oven-safe skillet. Leave space between pieces so air can circulate.
Add optional veggies: If using cherry tomatoes, onions, or potato wedges, toss them with a drizzle of olive oil, salt, and pepper, then scatter around the chicken.
Bake: Roast for 30–40 minutes, depending on size. The skin should be deep golden and crisp, and the internal temperature should read 175–185°F in the thickest part for super tender thighs.
Optional broil: For extra-crispy skin, broil for 1–2 minutes at the end.
Watch closely to avoid burning.
Rest and finish: Let the chicken rest 5 minutes. Squeeze a little fresh lemon juice over the top and sprinkle with 2–3 tablespoons grated Parmesan and chopped parsley or basil if you like.
Serve: Plate with the pan juices spooned over. Great with a simple arugula salad, roasted asparagus, or warm bread.
