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.

So easy, very delicious. I never even used the shallots (I forgot). I did use tomato paste in the tube – no waste of an entire can of paste that tends to get dried up or moldy in the fridge. I served it with roasted cauliflower and mini potatoes.
Agree that tomato paste in a tube is the way to go! Glad you enjoyed it.
This is excellent but it’s pretty robust. Wondering what you would think of adding white wine and heavy cream to soften it.
Hey Laura – Yes, you can modify the sauce. Try stirring 2 tablespoons of white wine in with the marinade and bake according to the recipe. Add up to 1/4 cup of heavy cream to the finished sauce. I think it will taste wonderful!
So easy and delicious. The family loved it! Thanks for making my dinner rotation more interesting.
A nice chicken dish with a lot of flavor, well balanced, robust, moist. Very good. We served it with a fresh garden salad with homemade ranch dressing and fresh corn on the cob. For those who wanted noodles, we had an artisan bucatini to make a bed upon. Our wine was a tasty red blend, Pure Paso by J. Lohr. Made me realize that mustard marinades are not my favorite. Will recommend to people who do like that. Because, although too mustardy for me, it was a great dish!
Made exactly as directed and it was fantastic! I was looking for an easy recipe for boneless skinless chicken thighs that wouldn’t be dry or hard to make. So glad I found your site!
Just delicious! One of the best marinades we’ve had! And it made our house smell wonderful. Thanks!
We enjoyed this very much. It was a little watery tho. Could I possibly use chicken breast with this?
Hi Maggie – Try using a slightly larger pan next time — that will help reduce the pan juices a bit. Yes, you can bake chicken breasts with this recipe. Reduce the time to 15-20 minutes to be sure they don’t dry out.
Thank you for the help. I assume I use boneless breast but, how small do I cut the too cook in 15-20 minutes? Can’t wait to try it with the white meat. Hum maybe I’ll give it a try with country style ribs too! The sauce was very good. Thank you.
Slice each breast in half horizontally. I hope you enjoy!
I had 3lbs of thighs and needed to increase the marinade so it would cover the entire top of the dish. Marinated 6 1/2 hrs. 5 stars is just about right! haha The flavors just went nuts and we all said lets do this again soon!
This is honestly my go to marinade. I bake or grill the chicken and sometimes leave it to marinate 2 days in the fridge. I never would’ve thought this combination would be so good.
This was so good! Made exactly as written and it was amazing. Full of flavor, but light. Had with a side of roasted carrots and brussels sprouts. Would be great with a side of mashed potatoes or cauliflower to soak up the yummy sauce. Thanks for posting this recipe! I will make again and again.
I made this tonight since I had to use up my chicken thighs! I subbed the herbs for Italian seasoning and used yellow onions instead of shallots! It was delicious!
This is one of our favorite go-to, weeknight recipes. It’s very tasty and uses ingredients we always have in the pantry. Highly recommend.
I don’t have any lemon, fruit, juice, vinegar or honey.. what can I use to substitute? I’m cooking it tonight.
Hi Debra, I’m not sure there’s a good substitute if you don’t have lemon, lime or vinegar. If you have dry white wine that could work well. Otherwise, add in an equal amount of chicken broth or water to loosen the marinade before baking.
What can I use instead of lemon. I have no fruit, or juice, or vinegar or honey. Thankyou
This marinade is so darn good! I too would like to make it into soup! I was licking the plate! Next time , I think I would marinate overnight to get more flavor into the chicken itself. Nevertheless,,this was quite tasty and I can’t wait to make it again! Thank you much!
Delicious! My husband, who says he does not like dark meat, was none the wiser!
This is a delicious recipe.. I used salsa in place of tomato paste… I didn’t have a tomato in sight aside from the salsa … Its a keeper.. so much so I would even use this recipe in a soup Its that good!..I’m not a left over person but I would eat this till it’s gone! I’m glad I ran across it! Thank you
Is this for 6 servings?
Yes, it serves 4-6 people. If you have hearty eaters, double the sauce and use 2-3 pounds chicken.
Thank you for the response! It was absolutely delicious!
I just made this and loved it! Super easy. No marinating time. I had everything on hand except for shallots, which I subbed with onions. Thanks for sharing! I will make this again!
I made this today, the only thing I changed is I used a small 8oz can of tomato sauce because I didn’t have paste. I marinated it for 24hrs and stirred it about 5 times and it was fork tender to cut and a great taste. I would have loved to post pictures here as I do on my FB and show my friends this.
Hi Gregory – Sounds like you made a great call substituting tomato sauce! If you’d like to share a photo on Facebook, tag @familystylefood
