The Best Chicken Thighs Ever. Full Stop.

I’m seriously so excited to share this one because I’m convinced these are the absolute best baked boneless chicken thighs out there. The flavor is next-level and the prep could not be easier; just a few simple ingredients and you’re on your way.

I like to bake a batch at the start of the week. We’ll have them for dinner in bowls or with a sauce, then I chop up the leftovers and use them in everything. If a recipe calls for rotisserie chicken, I just use this instead. It works in wraps, salads, sandwiches, pasta, you name it.

Ingredients In Baked Boneless Chicken Thighs

ChickenBoneless, skinless chicken thighs (they stay juicy and flavorful in the oven).
Oil + AcidOlive oil + balsamic vinegar (for richness and caramelized edges). I know it might sound a little strange, but as my 13-year-old always says: “trust the process,” haha.
SeasoningsChili powder, garlic powder, cumin, paprika, salt, pepper. It might seem like a lot of salt, but we’re using fine salt here, not kosher, so the measurement is just right.

Get Your Baked Boneless Chicken Thighs Perfect!

  • Grab a pack of thighs that are all similar in size so they cook evenly.
  • Pat the chicken dry before seasoning, so it cooks properly (instead of steaming).
  • Use a large sheet pan to give the thighs space to roast evenly without crowding.
  • Let the chicken rest before slicing, so the juices stay in the meat.
  • Line your baking sheet with foil for faster cleanup and to protect your pan.
  • Wait for the oven to be fully heated before adding in the chicken.

Baked Boneless Chicken Thighs

Baked boneless chicken thighs might sound simple, but this combo of pantry spices, olive oil, and balsamic vinegar gives big flavor with barely any effort.
These have a slight kick (my kids still eat them), but the spice is really mild once added to a dish or paired with a sauce.
Prep Time: 10 minutes
Cook Time: 22 minutes
Total Time: 32 minutes
Servings: 4 -6 servings

Equipment

  • Large sheet pan (15×21-inch), plus foil (heavy duty if possible)

Ingredients

Instructions 

  • Preheat oven to 425°F. Line a large sheet pan with foil. Pat chicken thighs completely dry with paper towels. No need to trim excess fat; it will render as the chicken cooks.
  • In a small bowl, whisk together olive oil, balsamic vinegar, chili powder, cumin, garlic powder, and paprika. Season to taste (I add 2 tsp salt & 1-1/2 tsp pepper). Rub or brush the seasoning mixture over the back first, and then the front of each thigh until evenly coated. You should use all the spice mixture.
  • Arrange chicken thighs flat on the prepared sheet pan, spaced out well. Bake in the center of the oven for 15 minutes.
  • Move the oven rack to 8 inches from the heat source. Switch to broil and cook for 7–10 minutes, or until the tops are nicely blackened and caramelized (watch closely).
  • Remove from oven, tent with foil, and let rest for 5–10 minutes. Slice or chop as desired.

Recipe Notes

Note 1: Choose chicken thighs that are similar in size for the most even cooking. Weigh them if possible to get as close to 2 pounds as you can. I typically use 6 thighs. If yours are larger, the bake time may need to be slightly longer.
Storage: Store leftovers in an airtight container in the fridge for up to 5 days or freeze for up to 2 months.

How to Use These Baked Boneless Chicken Thighs

  • Build a grain bowl with sliced chicken, rice, roasted veggies, and your favorite sauce.
  • Make tacos by adding the chicken to tortillas and your favorite toppings.
  • Upgrade your pasta by tossing in chicken or adding it to creamy mac and cheese.
  • Top a salad with sliced chicken, leafy greens, feta, and a punchy vinaigrette.
  • Create a sandwich by layering chicken onto toasted rolls with cheese and your favorite sauce.
  • Mix it into other meals like soups, stir-fries, or fried rice for a quick protein boost.

Storage

Storage and Meal Prep Tips

  • Store in the fridge in an airtight container for up to 5 days
  • Freeze leftovers by chopping or shredding the chicken and storing it in a freezer-safe bag for up to 2 months.
  • Reheat as needed using a skillet, microwave, or air fryer to warm and crisp.
  • Eat it cold in wraps or salads if you’re packing lunch or on the go.
  • Make a double batch of baked boneless chicken thighs for easy meal prep all week long!

Baked Boneless Chicken Thighs FAQs

Should I Marinate The Chicken First?

Nope! The balsamic and oil mixture acts as a quick seasoning and gives great flavor without needing time to marinate.

Can I Use Chicken Breasts Instead Of Thighs?

Unfortunately, chicken breasts don’t work well with this method since they’re leaner and tend to dry out quickly.

What’s The Best Way To Know When Chicken Is Done?

Use a meat thermometer and check for an internal temperature of 165°F. This is the safest and most reliable way to avoid under or overcooking.

Do I Need To Flip The Chicken While Baking?

Nope! You’ll get a nice caramelized, blackened top without flipping. Just leave space between each piece so they roast evenly and don’t steam.

Why Balsamic Vinegar?

It adds flavor depth and helps the chicken caramelize under the broiler. It might sound unusual, but it works so well.
