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.

As you know I live this, my sons love it, but I still don’t get why in your photos it seems like you use very little sauce. I quadruple recipe with lots of thighs, but even your times 3 only says 6 TBS of paste,oil and mustard??
Hi Debra! I’m glad this recipe is a favorite. The sauce is meant to be like a marinade. As the chicken cooks and releases juices, it forms a pan sauce. If there were more sauce to start with the chicken pieces would braise in the liquid, rather than roast. I hope that makes sense!
Really yummy!
Quick, easy, and delicious! Served with couscous. Great weeknight meal – will be adding to rotation!
So good!
Delicious and easy. Made as written. Will be making this again!
Delicious. I made this by the recipe with no substitutions. My shallots on top didn’t roast so next time I will slice them thinner and/or pop on the broiler for a few minutes. Very flavorful!!
So easy, so good! Used yellow onions. Served over leftover rice and orzo with a layer of spinach. The marinade was spot on!
Instead of suggesting cooking spray (container wastes resources, manufacturing it pollutes, and even if everybody puts their cans out for recycle, they may end up in landfill) and aluminum foil (eminently recycleable, but manufacturing pollutes, and let’s be honest: how many people actually put it in the recycle?) — would you consider recommending parchment paper? It’s cheap as anything, and can be put in municipal compost pick-up, if available, and the box can be put in paper recycle (removing the strip of sharp aluminum teeth) — ?
I’m so disappointed at how few online recipe sites give the slightest thought to reducing waste and pollution.
Yes, absolutely parchment paper is an option. The only time I advise against using it is when the pan is placed close to the heating element (such as when broiling) because it can catch fire.
This recipe is a keeper. The only thing I would change is I would use sweet onions instead of the shallots. My shallots got bitter and didn’t really add anything to the taste. I made asparagus and baby roasted potatoes. Everything was prepped ahead and went into the oven for an easy meal. I would serve over rice next time, because there was a surprising amount of liquid when it was finished cooking.
This recipe was amazing! My husband and I absolutely loved it! The tanginess of the mustard and lemon were simply out of this world. So easy, yet I would definitely make this for company. We are low carb right now so I just served it with green beans but it would be delicious with noodles too. The other thing I did was that since the marinade was tomato based, I added shredded mozzarella on the top of the thighs and it was so good! Thanks for this recipe!
Great recipe. I left out the chile flakes because my husband thinks he can’t tolerate them. It was full and savory nonetheless, and we both loved it. I added a little more olive oil and lemon juice to help it stretch a little farther. Thanks.
Lots of compliments! And the leftovers brought questions for the recipe from my husband’s colleague 🙂
thanks for the recipe I made it it was delicious and so easy!!
Easy, excellent. Made with roasted carrots and lentils. Also toasted a slice of 7 grain bread to mop it up
Very easy. Loved the flavors. Will definitely make it again.
I did not include the chili pepper, and it still had so much flavor after marinating for 24 hours – it was a hit and I will definitely make it again!
Loved it! Sending it to my daughter who came today for dinner and wants tomakeitfor her boyfriend,
Wonderful!Thanks for sharing, Carmen
I am not a mustard fan, but my husband is, so I gave this recipe a try for him. Wow! It is delicious!! It is now a family favorite even for this (former) mustard snob – lol. Blended with all the other ingredients it makes the most delectable sauce and the chicken could not be more tender or flavorful. Add in the ease of making and baking this and it is an all around winner! Thanks so much for this recipe.
forgot one thing- I added fresh pitted dates to the recipe. We find that adding them to almost any dish adds a dimension and appeal especially to the younger family members.
Thanks for sharing that tip – I wouldn’t have thought to add dates!
fast, easy to prepare, and the best thing- everyone from grandparents(that’s me) to grand children love it. I just took down the amount of pepper , but that’s all. guests asked for the recipe and that’s not something that happens all the time.
