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.

I made this tonight and was very good. I only had Dijon horseradish mustard and it was still very good. First time seeing your post and I love the way you post your recipes, no guess work and love the tips.
Can I use chic breast in this recipe?
Yes, you can! Slice them in half and reduce the baking time 5-7 minutes.
Made this a few times. It’s my son’s favorite chicken recipe and he is a picky eater even tho he’s an adult now.
Hi! This was a good quick recipe ! The chicken had a nice tangy flavor .. I roasted some potatoes on a different pan to serve with the chicken, but wonder if all could be done in the same pan ?
Hi Tricia – If you want to add potatoes for a one-pan bake, I suggest first parboiling the potatoes for about 10 minutes (cut them into about 1 1/2-inch pieces), then add to the baking dish with the chicken. Be sure to use a slighter larger pan so everything can cook in one layer.
Made as written, doubled the sauce. Marinated for 4 hours. Absolutely delicious! Highly recommended.
Really delicious! I wasn’t sure how the mustard and tomato paste were going to come together, but it really was a wonderful dish, enjoyed by whole family. Love the sauce! Thank you for the recipe!
Recipe was super yummy. My one issue was it was watery instead of carmelized. I used 10 thighs so I used more paste and mustard, etc. Still overall an excellent flavour and I will make it again.
Thanks for sharing, Shelley! If you make this again with 6 or more thighs, try using a slightly larger pan. The wider surface area will help concentrate the pan juices.
I was looking for a new way to prep the chicken thighs yesterday evening … I was stuck in a rut of three recipes on my rotation; then I came across this one. It sounded quick and easy, I had all the ingredients, and so we went ahead. Well, this was so incredibly delicious that we almost licked our plates. I only had 5 thighs (just myself and my husband) but I made all the sauce because we like lots of sauce and it was to die for. I immediately defrosted more thighs and made two batches this morning which I vac sealed and popped in the freezer for even quicker meals or nights when we don’t want to cook. Thanks for this recipe, I will look around on your site for more!
So glad you enjoyed! You might like this chicken thigh recipe with lemon and rosemary: https://familystylefood.com/roasted-chili-chicken-thighs-with-lemon/
This marinade is fantastic. However the cooking time was way over what was needed. The chicken was overcooked.
Glad you liked it! If you find your chicken is fully cooked before the stated cook time, it could have to do with the size of the thighs and the particular oven (some run hotter/cooler than the set temp). An instant read thermometer is very helpful to determine doneness – anywhere between 160-165 is considered safe.
Really good!!! I made 1 1/2 times the sauce with 8 chicken thighs and I would do that again (I like things saucier). My family loved it (except for the kid who hates dark meat and he loved it until he realized it wasn’t white meat- which was after the first piece).
I do 8 times the amount because I use a lot of chicken, but after cooking there’s a lot of sauce which is not thick. Am I doing something wrong? First time I made it using exact amounts there was barely enough to spread around. How should it look when done? should sàuce be thick still?
Hi Debra: Are you baking 8x the amount of chicken, including 8x the sauce? That would be 14 pounds of chicken. If so, it’s best to use multiple baking dishes or pans that contain the chicken without crowding it too much. If there isn’t much air circulating around the chicken it will steam rather than roast, creating a lot more juice. Ideally, the finished pan juices will be saucy, but not too liquidy.
I made this. Followed the recipe exactly. Not impressed, unfortunately. I think it may be the combo of lemon juice and tomato paste in the sauce. Just seemed a bit acidic and wonky with heat.
I absolutely loved this recipe!!!! I made it as the recipe read – no changes, no subs. It is a keeper.
Thank you!
Ive been using green onions because I’ve never had shallots, but am going to buy them tonight. However wwhenn I looked up shallots it says don’t brown them because like garlic they get bitter. The recipe says to let them brown. What should I do?
Hi Debi, The shallots won’t get too brown in this recipe, just crisp on the edges. If you’re worried you won’t enjoy the slightly caramelized flavor, tuck any the shallots under the chicken so they’re not exposed.
My son’s and I love this recipe. However over and undercooking meat always worries me. Why do you bake it on high temperature? I e been cooking it longer at 325 because I worry about not cooking chicken long enough.
Hi Debra – Higher oven temperatures (400-450 degrees) work great for boneless, skinless chicken thighs. That temperature helps them cook quickly, and it adds a little sear on the outside, which adds flavor. It’s fine to bake them at 325 degrees, but they should take longer to cook and won’t turn out as browned. Lower oven temperatures are excellent for whole chickens and pieces that have bones and skin, because at hotter temps the skin will brown too quickly (and burn) before the meat is cooked through.
D.B. why does heat have to be so high. I always worry about over or under cooking meat. I’ve made this many times, but at 325. Is that a problem?

I I did . My family loved it!!!
Hi . I wasn’t sure if you bake the chicken covered or uncovered?
Hi Jane – Bake it uncovered.
This is a staple recipe now. It’s so easy and delicious!
Love this. I’m on Atkins diet though how many carbs in each thigh? And I only have toaster oven. What temp do I use
Hi Debra – There are 11 grams of carbs per thigh (including the sauce). Set your toaster oven to 425 degrees. You may want to set to broil for the last few minutes, depending on how your toaster oven works.
I will give this recipe 4 stars because the chicken was perfect and juicy, but I didn’t love the sauce which I found odd because I LOVE Dijon and everything else in the ingredient list. I did marinade for about 6 hours.
