Bake Boneless Chicken | How Long To Bake Boneless Chicken Thighs At 400?

Boneless chicken thighs are the perfect addition to your favorite recipes. They’re versatile, flavorful, and great for meal prep. But how long do you cook boneless chicken thighs in the oven? There are a few different ways to cook boneless chicken thighs that can affect their final results. Here’s everything you need to know about this delicious staple!

Boneless Chicken Thighs Baking Time

The baking time for boneless chicken thighs depends on a few factors.

  • The size of your chicken thighs: The smaller the chicken thighs, the shorter their baking time will be. If you’re cooking two batches of different-sized chicken thighs, use separate oven racks to prevent over-baking smaller pieces that might dry out if left in the oven too long.
  • The temperature of your oven: You can bake boneless skinless chicken with no oil at 400 degrees F (204 C), but do not exceed 425 degrees F (218 C). If you want to go higher than that, add some spray oil or brush it on before placing them in the oven—anything more than 450 degrees F (232 C) is likely to burn before they’re done cooking through.

How Long To Bake Boneless Chicken Thighs At 400?

Bake boneless chicken thighs for about 30-35 minutes at 400 degrees. This is the perfect temperature to cook them through and still leave them juicy and tender on the inside, with a crispy skin that’s golden and crunchy on the outside. If you want to bake your chicken longer, add 10 minutes per pound of chicken before checking its doneness again by piercing it with a fork or knife.

What Is The Best Temperature To Bake Boneless Chicken Thighs In The Oven?

When you bake boneless chicken thighs in the oven, it’s important to know what temperature you should cook at. The most common temperature is 400 degrees Fahrenheit. However, if you prefer to cook your meat on higher heat and get it done faster, 425 degrees may be the better option for you.

If you’re cooking for a large group of people or have a lot of food to prepare, this could make all the difference in how long it takes for everything to be ready at once.

Do Boneless Chicken Thighs Cook Faster Than Bone-in?

If you ask any cook, they’ll tell you that boneless chicken thighs cook faster than bone-in. This isn’t surprising, as the bones help to insulate the meat and keep it from drying out during cooking. Bone-in chicken thighs need longer cooking times to break down the connective tissue in the meat and make it tender enough for your liking.

Boneless thighs are more tender than bone-in too! The absence of bones makes them much easier to cut into uniform pieces so that they’ll all bake evenly; this means that you can get slightly quicker results with less fuss!

Ingredients for Baking Boneless Chicken Thighs

In order to prepare the best, most flavorful boneless chicken thighs possible, you’ll need some ingredients.

  • Fresh chicken.
  • Olive oil or other cooking oil of your choice (vegetable, canola, etc.).
  • Spices—I recommend using thyme and rosemary for this recipe; you can use whatever spices you like best! Just be sure not to go overboard with them because they can get overpowering if added in large quantities.
  • Kosher salt and black pepper (freshly ground is best).

Best Different Ways To Season Boneless Chicken Thighs

There are so many different ways to season boneless chicken thighs, but here are a few of the best:

  • Salt, pepper, and garlic powder – Sprinkle on your favorite seasoning blend before baking or add some garlic salt, oregano, and black pepper to taste
  • Lemon juice, olive oil, and parsley – Drizzle lemon juice over the chicken thighs before baking them; then add chopped fresh parsley (it will cook down into their flavorful juices) after they’re done cooking
  • Honey mustard sauce – Mix together the honey mustard sauce with chopped onion until it forms a thick paste (this works best if you add some extra water) then coat your chicken pieces in it before baking
  • Soy sauce + garlic – marinade overnight in soy sauce mixed with minced garlic cloves
  • Cumin, chili powder, and paprika – Sprinkle your favorite spice blend over the chicken thighs before baking them; then add some olive oil to create a crispy skin on top.

How to Tell They Are Done

When you are sure that your chicken thighs are done, remove them from the oven and let them rest for at least five minutes before serving. The internal temperature of the meat should be 165 degrees Fahrenheit, which is slightly higher than other types of poultry (150 for whole chickens). If your skin is crispy and browned all over, it’s good to go!

To ensure that your chicken thighs are cooked through and juicy, check the texture by inserting a thermometer into the thickest part of each thigh without touching bone or fat. If you’re still unsure after checking this method for several minutes, check another spot on each thigh until you’re satisfied with its readiness.

How Long To Bake Frozen Boneless Chicken Thighs At 400?

If you’re cooking frozen chicken thighs, the process is a little different. You’ll need to make sure that your oven is preheated to 400 degrees Fahrenheit before placing your thighs in it for 45-50 minutes. Also, don’t forget to check the internal temperature with a meat thermometer after removing them from the oven!

How Long To Bake Boneless Chicken Thighs Air Fryer?

Boneless chicken thighs will bake for about 20 minutes in the air fryer. The process is very similar to baking them in the oven. However, you’ll want to use a lower temperature (around 400 degrees) and flip your chicken once during cooking so that both sides are evenly cooked. This will help retain more moisture than if you were just leaving them alone for a longer period of time.

To get started, preheat your air fryer to 400 degrees for 10 minutes before adding the chicken thighs. Once they’re ready, place them on a wire rack and brush each side lightly with oil or melted butter before placing them into the basket of your air fryer for about 20 minutes total until golden browned and fully cooked through!


So, if you want to bake boneless chicken thighs at 400 degrees for 30 to 35 minutes, that should work just fine. You can also try baking them at 350°F for 30 minutes and see if they turn out any differently. Just remember: The key here is not to over-bake the meat so that it ends up dry or tough. Keep an eye on things as they cook and remove them from the oven when they’re ready so they don’t become too tough while cooking.
