Baked Boneless Skinless Chicken Thighs
This post may contain affiliate links. Please read my disclosure policy.
Boneless skinless chicken thighs are the part of the bird that actually benefits from oven heat — the fat keeps them juicy at high temperatures where a breast would dry out. Baked at 425°F for 25 minutes, they come out tender with caramelized edges and enough pan sauce to spoon over everything on the plate.
The marinade for these chicken thighs came together on the fly in an Airbnb kitchen — Dijon mustard, tomato paste, lemon juice, garlic — and it’s stayed in my steady rotation ever since. It takes two minutes to mix and no time to marinate, and the tomato paste creates a glaze that sets into a crust at high heat.
What readers are saying:
“This recipe was amazing! My husband and I absolutely loved it! The tanginess of the mustard and lemon were simply out of this world.”
Key ingredient notes
- Boneless, skinless chicken thighs: The fat content is what makes this cut reliable at high oven heat — thighs have roughly twice the fat of a breast, which means they stay moist while the exterior caramelizes. A breast at 425°F for 25 minutes would be dry; a thigh at the same time and temperature comes out tender with some crust. The one thing that causes problems is overcrowding — if the pieces are packed too tightly, they steam rather than roast and you lose the crust. Use a pan just large enough to hold them in a single layer with a little room between pieces.
- Marinade: The combination looks casual but it’s built on balance — the tomato paste brings concentrated sweetness and body, while the Dijon and lemon juice provide the acidity that cuts through the fat in the chicken and keeps the flavors sharp. Together they create a coating with enough sugar to caramelize at high heat and enough acid to act as a quick tenderizer. Mix the marinade and chicken in the morning, refrigerate all day, and the flavor will be noticeably deeper by the time it hits the oven.
- Shallots: They’re worth seeking out rather than defaulting to onion. Their higher sugar content means they caramelize cleanly at high heat without turning bitter — at 425°F, the exposed pieces crisp at the edges while the pieces tucked under the chicken get soft and sweet. That contrast in texture is part of what makes the dish. If you can’t find shallots, red onion is the closest substitute, though it will be sharper and less sweet in the finished pan sauce.
How to bake boneless skinless chicken thighs
1. Use a baking dish just large enough to hold 6–8 thighs snugly — 2 to 3 quarts is ideal. A pan that’s too large causes the pan juices to spread and evaporate before they can form a sauce. 2. Whisk the marinade ingredients until combined. The mixture will look thick — that’s the tomato paste and mustard doing their job. A concentrated coating adheres to the chicken better than a thin one.
3. Toss the chicken with tongs so that the pieces are evenly coated. 4. Tuck the shallots in between the thighs rather than piling them on top. The pieces nestled under the chicken will soften into the pan sauce; the exposed ones will crisp at the edges. At this point you can bake immediately or cover and refrigerate up to 24 hours. 
5. Bake uncovered at 425°F for 25–30 minutes, until the juices are bubbling and the shallots are golden. The chicken is done when it reaches 165°F internally — a thermometer is better than guessing.
What to serve with baked chicken thighs
These thighs are substantial enough to anchor a simple weeknight plate. Fresh green bean almondine is a natural pairing — the brightness of the lemon cuts through the richness of the pan sauce. Crispy smashed potatoes are a good call — the garlic and rosemary echo the marinade without competing with it. For a lighter option, marinated white bean salad doesn’t need cooking and holds up well alongside the pan sauce.

Recipe Video
Ingredients
- 1½ – 1¾ pounds (680 g) boneless, skinless chicken thighs (6-8 pieces)
Dijon marinade
- 2 tablespoons (30 g) Dijon mustard
- 2 tablespoons (30 g) tomato paste
- 2 tablespoons fresh lemon juice
- 2 tablespoons (30 ml) extra virgin olive oil
- 1 tablespoon (15 g) chopped fresh thyme, or 1 teaspoon dried thyme
- 1-2 finely chopped or grated garlic cloves
- 1 teaspoon kosher salt
- ½ teaspoon freshly ground black pepper, or to taste
- ½ teaspoon crushed red chili pepper
- ¾ cup (120 g) sliced shallots (about 2 medium)
Instructions
- Preheat the oven to 425 degrees.
- Put 1½ – 1¾ pounds boneless, skinless chicken thighs (6-8 pieces) in a medium (about 3-quart capacity) baking dish. If your pan/dish is not nonstick, spray it with cooking spray or line with a sheet of aluminum foil for easier clean-up. Note: Your goal is for the chicken and shallots to roast in the oven while making a delicious pan sauce at the same time. If your pan is too large the juices will evaporate.
Mix the marinade
- Whisk together 2 tablespoons Dijon mustard, 2 tablespoons tomato paste, 2 tablespoons fresh lemon juice, 2 tablespoons extra virgin olive oil, 1 tablespoon chopped fresh thyme, 1-2 finely chopped or grated garlic cloves, 1 teaspoon kosher salt½ teaspoon freshly ground black pepper and ½ teaspoon crushed red chili pepper in a medium bowl.
Assemble and bake the chicken
- Pour the marinade over the chicken and turn the pieces over to coat. Scatter ¾ cup sliced shallots (about 2 medium) over the chicken, poking them in between the thighs here and there. Some of the unexposed shallots will crisp and brown, while the covered pieces will bake and soften.
- You can bake the chicken immediately or cover and refrigerate the chicken and marinade up to 24 hours ahead.
- Bake the chicken uncovered 25-30 minutes, until the chicken is opaque and the juices are bubbling. Serve warm.
Karen’s Notes and Tips
- Marinate the chicken overnight in the mustard mixture and bake directly from the fridge — add 5 minutes to the cook time if the chicken is cold.
- Freeze the unbaked chicken in a freezer-safe bag. Thaw overnight in the fridge and bake.
- Optional: Add 1 cup of cherry tomatoes to the baking dish with the marinated chicken — they will burst and release their juice into the sauce.

To the rescue!
I had some chicken thighs in the refrigerator and no clue what to make my family of 5 for dinner. I didn’t want to make the same ole BBQ. I googled something and this popped up. I had everything on hand, and boy am I glad!! This is so delicious, although I had zero marinade time!! This cooked up in 30 minutes with minimal mess. I’m obsessed with the flavor. Very Tuscan. Thank you!
This was so good! Quick, easy, different. The only thing I’ll change next time is to make more marinade so I can have more gravy. Other than that, it was a hit! I may try it with chicken breasts eventually too!
Haven’t bothered you for awhile, but two questions. The oil is difficult to mix in. Second, does Dijon change flavor alot rather than yellow mustard? It’s 99 cents for large yellow, and 2.00 for tiny Dijon. Thanks.
You can use yellow mustard instead of Dijon, but the sauce could taste a bit more acidic (yellow mustard has a sharper flavor). You can reduce the lemon juice by half to adjust. Try whisking the oil into the other ingredients until it’s emulsified. It’s okay if some oil is on the surface after baking.
This was really good! As easy as can be, and tastier than expected! I used 1/2 of a thinly sliced red onion and it came our great. Ill use more onions next time since their sweetness countered the sauce perfectly. I mixed the onions and chicken with the sauce so everything was coated.
Hi, I’m curious if you’ve tried this recipe with mahi mahi or a white fish? It was lovely with the chicken but would like to try fish.
Diana – I haven’t tried this recipe with fish, but I think it would be delicious – especially with cod or halibut! I would advise baking the fish about 20 minutes or until it flakes.
Ok, first, I’m not a great cook. Next, I don’t “post” online. Finally, my family doesn’t say much about dinner – but this recipe got RAVE reviews!! Like, everyone said how incredibly delicious this was! What more is there… Lol.
Thanks so much for a great new recipe!!
Delicious with grey pupon mustard and try adding sun dryed tomatoes.
Freaking bomb!! Chicken was so moist. Didn’t have shallots, used leeks, didnt have thyme, used italian seasoning. This was super tastie. Thanks for the recipe.
Sorry to bother you again, but I notice photo doesn’t have much sauce. Being a chef, I’m sure you have a reason. What is it? I do notice the more sauce, the greasier, tho still perfection taste wise. Just curious! Do you have video of how you prefer to do it?
The pan sauce is created by the marinade and chicken juices as it bakes. Using a baking dish that just fits the thighs in one layer is best. A larger dish will have more surface area, which will evaporate the sauce. You can see a video of the recipe here: https://www.youtube.com/watch?v=CDCL6YGSBdk
Hello
I wondered since my boys eat this like they haven’t eaten in a year,, I make several pans at a time, in fact I’m still at it now, but I put 10 thighs in a pan at a time, so how long should I bake it? You say 25 to 30 minutes, so does that the same for 10 thighs?
Thanks. Happy Easter.
Yes, the baking time should be about the same.
Hello Karen, is it okay to do this recipe if they are not boneless? Or should i adjust the cooktime?
Hi Jasmine – Yes, add 10-15 minutes additional cooking time for bone-in chicken pieces.
Yummy will definitely make again! I didnt even marinate it still was delicious!
Dear karen.we eat this many times a month. Favorite dish. My two 200 lb sons eat two trays at a time. I know I’m cheating on Atkins, but still lost 80 lbs. Please publish more low carb recipes as we live on chicken, pork, roast beef, burger etc. No5 spicy as my son hass Crohn’s. However you’re our favorite chef now.
I can’t eat pasta,bread,pots,carrots,peas,etc. But oil,butter,cheese on eggs,sour cream ok.
And bacon of course. Any ideas would be appreciated,as thlghs best thing ever!

Hi Debra – I’m so happy you love this dish!! You can try this low card chicken thigh recipe https://familystylefood.com/roasted-chili-chicken-thighs-with-lemon/ and also this steak salad (omit the rice noodles) https://familystylefood.com/thai-steak-salad-recipe/
I’m teaching my son to cook (at his request) and I gave him this recipe and let him go. I just supervised. It was so easy, but It was amazing. The whole family loved it! Thank you so much!
Did not like this. The combination of mustard, tomato paste and lemon juice are flavors that do not go well together.
Yes they do, you just don’t like it cause you’re so vanilla. Karen I come from a family with famous restaurants in Spain and Italy and this recipe is delicious!
That’s wonderful to hear thank you!
I made it tonight. It passed the tastes test by the fussy partner. However, is it supposed to be a thin syrup? I loved it and will make it again.
Hi Nanci – So glad you enjoyed! The sauce should be juicy, but not too thin. If you added mushrooms instead of shallots, keep in mind they release a lot of water. Try using a slightly larger pan so the sauce can reduce while it bakes.
doing it today, adding mushrooms as I don’t have shallots.
Delicious and so easy! The whole family loved it.
ABSOLUTELY DELICIOUS!!! MY BELT WAS NOT READY 😋🤌🥰
Made this after a search for something different to make with chicken thighs that wasn’t my usual east Indian or Mexican flavors. I’m glad I tried this, so easy and delicious. I doubled the sauce like others suggested and it was awesome. I didn’t have shallots, so I substituted onions without a problem . Thanks for a nice dish for something different.
