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.

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.

Wow! I loved this recipe. I made it this week and living alone, got to eat it 3 nights in a row 🙂 I served it with wild rice and green beans. Just perfect.
I did have some cherry tomatoes that were getting long in the tooth so I added them, which I think helped with keeping them saucy for leftovers. Absolutely delicious! Thank you
I’m excited about making this for Thanksgiving! How would you adjust temp and timing for a mix of breasts and thighs?
Hi Susie – It might be best to separate them, one pan for breasts and one for the thighs. You can slice the breasts in half horizontally and bake about 20 minutes. Happy Thanksgiving!
Can I make this with tenders??
Amanda, you can try this with chicken tenders, but the cooking time may be shorter by 5-10 minutes depending on their size.
This was delicious, and I’ll definitely be making this again! I followed the recipe exactly as written!
Would never have thought to put this stuff together, but it works! Very easy and super tasty. Well done and thank you
Love the recipe. It was yummy. Can you use bone-in skin on thighs?
Hi Jackson – Yes, you can! I would suggest baking them 15-20 minutes longer.
I must have commented on this in the past, but just in case, this is a wonderful and clever recipe! I have made it many times and we all love it! I will add that I use Sundried Tomato Paste in place of regular as it has the most wonderful flavor! After my daughter bought it by accident once, we have used nothing since!
I visit your site often Karen, and am never disappointed.
Thank you!
Thank you so much, Carla! I love hearing that you’ve made this chicken again and again – yay 🙂 And using sun-dried tomato paste is such a great idea! I can just imagine the flavor boost. I’m so happy you’re enjoying the recipes.
It’s good. However the cooking method of letting it stew in the drippings makes the seasoning fall off the chicken and its texture is different than I prefer. I might try again, instead cooking it on a wire rack to see if that helps.
I stumbled across your website by accident looking for inspiration and I wasn’t disappointed when I found this chicken recipe. This dish is not only flavoursome, it is one of the easiest mid-week meals to prepare! No marinating, used baking paper instead of foil, purple/Spanish onion instead of shallot, substituted lemon for Balsamic Vinegar of Modena and that sweet twist was a real hit and a sure fire winner in our household! Served with steamed ancient grains with sauteed buttered mushrooms. Thank you Karen! This delicious chicken recipe has been added to our family favourites list.
I’m so glad you found your way here! And the swaps you made sound perfect — balsamic for lemon sounds like such a good twist (I may have to try it myself:)
I want to marinade this overnight/make this the night before but scared to do so b/c of the lemon juice, I’ve read online it’s bad to do, are you sure it’s ok?
Hi Michele, You don’t need to worry if you refrigerate 12-24 hours ahead — the 2 tablespoons of lemon juice in this marinade is a small amount compared to the other ingredients. It’s not strong enough to “cook” the chicken like you may have read about happens with large amounts of citrus. If you’re not sure, you can leave the lemon juice out, and stir it into the chicken before you bake.
Thank you so much!!
My pleasure! I hope you enjoy it:)
Delicious, fast and easy. I didn’t have lemon and subbed apple cider vinegar. Liked by the whole family.
This came so good! I baked it on top of small red potatoes that I boiled ahead of time and they sucked up some of the drippings. I served it with a side of steamed string beans. I’m definitely making it again.
Great little recipe. Husband and son agreed. Thanks, Karen.
Delicious. I make this all the time. Thank you 😊
Yay – so happy to know that Jan!
Making it now. Can’t wait to try. I’ll be back.
i thought the marinade was going to be v sharp and acidic so I added honey which diminished the sharpness. The chicken was quite good but the marinade was a little bitter. I convinced myself that you had forgotten to add something to counteract the lemon, tomato paste and the mustard. Thoughts…
Hi Shelia – Thanks so much for sharing your tweak! I’m guessing you might prefer a slightly sweeter balance of flavors, so the honey makes sense. The chicken marinade gets its depth from the mix of lemon, tomato paste, and mustard, which is more tangy-savory than sweet. If you make it again, you might try swapping the lemon juice for balsamic vinegar, which will add less acidity and natural sweetness that might hit the right note for you.
First, congratulations on having over a 1000 reviews and a 4.99 rating.
I didn’t think I would like this, but I had to try it just because it was rated so highly… and we loved it! Everyone loved it… me, hubby, kids.
Thank you Karen!
Wow, thank you Debbie! I’m thrilled (and honored) that you gave the recipe a shot, and even happier to hear the whole family loved it. Getting the thumbs-up from everyone is always a win in my book. 😊
I have to say, I was not expecting much from this recipe. Was I wrong. That was so good. Can’t wait to check out the rest of your site.
Karen, do you think doubling this recipe for a big group would work?
Hey Carol – Yes, for sure! If you’re doubling the recipe, be sure to use 2 baking pans of a similar size.
Thanks, great idea!
My pleasure – I hope you enjoy!
Excellent recipe. My husband suggested that I use this marinade with shrimp. Does that sound like it would work? If so, any suggestions?
Should I marinate the shallots with chicken and marinate or put them in before cooking ?
Yes, they can marinate with everything, infusing even more flavor.
