How Long to Cook Large Chicken Thighs in the Oven at 400°F

Large bone-in, skin-on chicken thighs usually need about 45–55 minutes in a 400°F (205°C) oven; the exact time depends on their size and your oven. This recipe seasons them with paprika, garlic, herbs, and lemon, then roasts them skin-side up until a thermometer confirms they are safely cooked.

Ingredients

4 large bone-in, skin-on chicken thighs, about 2½–3 lb (1.1–1.35 kg) total
1 tbsp olive oil (15 ml)
1 tsp kosher salt (5 g; use a little less if using fine table salt)
½ tsp freshly ground black pepper (about 1 g)
1 tsp sweet paprika (about 2 g)
1 tsp garlic powder (about 3 g)
½ tsp onion powder (about 1.5 g)
½ tsp dried thyme (about 0.5 g)
1 tbsp lemon juice (15 ml), plus lemon wedges for serving if desired

Instructions

Heat the oven and prepare the pan. Set a rack in the center of the oven and preheat to 400°F (205°C). Line a rimmed baking sheet with foil or parchment for easier cleanup. For a less greasy, more evenly crisped underside, set an oven-safe wire rack on the sheet and lightly oil it. Preheating while you prepare the chicken keeps it from waiting around before roasting.
Dry the thighs and mix the seasoning. Use paper towels to pat the chicken dry, including around the edges of the skin. Do not rinse raw chicken; splashing can spread raw juices around the sink and counter. In a small bowl, combine the salt, pepper, paprika, garlic powder, onion powder, and thyme.
Season all sides. Drizzle the oil and lemon juice over the thighs and rub them over the meat. Sprinkle the seasoning mixture across the thighs, including the sides. If the skin is loose, gently slide a finger underneath it and work a little seasoning onto the meat without tearing the skin. Place the thighs skin-side up on the prepared pan, leaving space between them so hot air can circulate. Wash your hands and any surfaces that touched raw chicken.
Roast until cooked through. Bake for about 45–55 minutes, without turning the thighs. Begin checking at 40 minutes if the pieces are closer to 10 ounces (280 g) each or your oven tends to run hot. Insert an instant-read food thermometer into the thickest part of each thigh, avoiding the bone. The USDA FSIS safe minimum internal temperature for poultry is 165°F (74°C); check every thigh, since pieces can finish at different times. If the skin is browned before the meat reaches that temperature, loosely cover the skin with foil and continue roasting. If the chicken is cooked but the skin needs more color, broil briefly while watching closely so it does not burn.
Rest and serve. Transfer the thighs to a clean plate or board and rest for 10 minutes before serving. The rest gives the juices time to settle and makes the meat easier to handle; it is not a replacement for reaching 165°F (74°C) during cooking. Spoon any pan juices over the chicken, and offer lemon wedges at the table.

Tips

Use weight and temperature, not the clock alone. A large thigh can weigh very differently from another one, and ovens vary. Bone-in thighs often take longer than boneless thighs, while a crowded pan can slow browning. Use the 45–55-minute range as a guide and let the thermometer decide when the chicken is done.
Keep the skin dry. Drying the skin before adding oil and seasoning helps it brown. Avoid covering the pan during the main roasting time, since trapped steam softens the skin. If using parchment, keep it flat on the sheet and away from the broiler element.
Adjust the salt to your seasoning. The recipe uses a modest amount of kosher salt. If your spice blend contains salt, reduce the added salt; if using fine table salt, use less by volume because its crystals pack more tightly. Dried rosemary or oregano can replace thyme, though both have a stronger, more distinctive flavor.
Make the work easier without leaving raw chicken out. You can mix the dry spices ahead and refrigerate them in a covered container. Season the chicken shortly before baking, or refrigerate seasoned thighs covered and cook them within a day. Do not leave raw poultry at room temperature while the oven heats.

Serving Suggestions

Serve the thighs hot with the pan juices and lemon wedges. Their savory seasoning works with simple sides that can cook while the chicken roasts: roasted potatoes or carrots, steamed green beans, broccoli, or a crisp green salad. Rice, couscous, or crusty bread can soak up the juices, while a spoonful of plain yogurt or a mild herb sauce provides a cool contrast. If you roast vegetables on the same pan, make sure they do not crowd the chicken; use a second sheet pan if needed so the skin has room to brown.

For a casual dinner, pull the meat from the bone after resting and serve it with flatbread, slaw, and a squeeze of lemon. Keep the chicken separate from ready-to-eat foods while handling it, and use a clean serving platter rather than the plate that held it raw.

Variations

Smoky and warm: Replace the sweet paprika with smoked paprika for a deeper, woodsy flavor. Add a small pinch of cayenne if you like heat. Smoked paprika is widely available; if you do not have it, regular paprika still works, though the chicken will taste less smoky.

Lemon-herb: Use dried oregano in place of thyme and add 1 tsp (about 2 g) finely grated lemon zest to the seasoning. Fresh rosemary can also work, but chop it very finely so it distributes evenly. Serve with extra lemon after roasting rather than adding extra juice to the pan, which can make the skin less crisp.

Boneless thighs: This seasoning also suits large boneless, skinless thighs, but they generally cook faster. Start checking around 25–30 minutes at 400°F (205°C), then continue as needed until the thickest pieces reach 165°F (74°C). Their surface will not become crisp like skin-on thighs, and their exact timing depends on thickness.

Use a different oil or herb: Avocado oil or another neutral cooking oil can replace olive oil in the same amount. If thyme is unavailable, use dried oregano or rosemary. These are practical swaps rather than exact flavor matches: oregano is more pungent, while rosemary is piney and can dominate if used generously.

Storage and Reheating

Refrigerate leftover chicken within 2 hours of cooking, in a shallow airtight container. It keeps for 3–4 days in the refrigerator. For longer storage, freeze it in a freezer-safe container or bag; for best quality, use within about 3 months. Let frozen portions thaw in the refrigerator rather than on the counter. Store the meat with a little pan juice if available to help it stay moist.

To reheat, place the thighs in a baking dish with a spoonful of water or pan juices, cover loosely with foil, and warm in a 325°F (165°C) oven until the center reaches 165°F (74°C). The time varies with portion size and whether the chicken is chilled or thawed, so check with a food thermometer rather than relying on a set number of minutes. For crisper skin, uncover for the final few minutes. You can also microwave individual portions covered, turning or rearranging them if needed so they heat evenly; leftovers should reach 165°F (74°C) whichever method you use.

Frequently Asked Questions

How long do large chicken thighs take at 400°F?

For bone-in, skin-on thighs weighing roughly 10–12 ounces (280–340 g) each, plan on about 45–55 minutes at 400°F (205°C). Smaller pieces may finish sooner, and especially thick ones may need longer. Check the thickest part of each thigh with a thermometer and remove them only after they reach 165°F (74°C).

Should I bake chicken thighs covered or uncovered?

Bake them uncovered for browned, crisping skin. Covering traps steam and tends to soften the skin. If the surface becomes very dark before the center is cooked, loosely tent the pan with foil for the rest of the bake; take the foil off near the end if you want to restore some crispness.

Do I need to flip the thighs while they bake?

No. Arrange them skin-side up and leave them in that position so the skin can brown. Turning them is unnecessary and can disturb the skin. If your oven browns unevenly, rotate the pan once during cooking, taking care not to spill hot juices.

Can I cook chicken thighs from frozen?

For this recipe, thaw the thighs in the refrigerator first so they cook more evenly and the seasoning can coat the surface. Cooking frozen thighs requires a different, longer timing, and the outside can brown before the center is ready. If you do cook from frozen, do not guess at doneness: check each piece in its thickest part and ensure it reaches 165°F (74°C).

Why are my chicken thighs still pink near the bone?

Color alone does not reliably show whether poultry is safely cooked. Pigment near the bone can remain pink even when the meat has reached a safe temperature, and cooked meat can also vary in color. Use a thermometer in the thickest part without touching bone; the target is 165°F (74°C).

Can I prepare the thighs ahead?

Yes. Mix the spices in advance, or season the raw thighs and keep them covered in the refrigerator until you are ready to bake, preferably within 24 hours. Keep raw poultry refrigerated and separate from ready-to-eat foods. If you mean cooking the chicken ahead, refrigerate it promptly after roasting and reheat leftovers to 165°F (74°C) before serving.
