Sticky Balsamic Chicken Thighs with Garlic

These balsamic chicken thighs are a simple, flavorful one-pan dinner you can make on the stove and finish in the oven. The chicken soaks in a tangy-sweet balsamic marinade, then bakes with cherry tomatoes and gooey mozzarella pearls. Serve over pasta, a grain, or a green salad for a complete meal.

This recipe works wonderfully when you prepare the balsamic marinade ahead of time — marinating the chicken for at least an hour (or overnight) builds deep flavor. The method is straightforward: marinate, sear in a heavy skillet, deglaze and reduce the sauce, add tomatoes, then finish in the oven with mozzarella and fresh basil.

What You Need for Balsamic Chicken Thighs

For the balsamic chicken marinade

• Balsamic vinegar: Adds a rich, tangy-sweet base and helps tenderize the chicken.
• Olive oil: Provides body to the marinade and helps carry flavors.
• Dijon mustard: Gives a bright, tangy note and helps emulsify the marinade.
• Brown sugar: Balances acidity with a touch of sweetness for caramelization.
• Dried thyme: Adds an earthy, herbal accent.

For the chicken and sauce

• Boneless, skinless chicken thighs: Tender and forgiving; they absorb the marinade well.
• Olive oil (for cooking): For searing the chicken to a golden crust.
• Dry white wine or broth: Used to deglaze the pan and add depth to the sauce.
• Tomato paste: Concentrated tomato flavor that thickens and enriches the sauce.
• Cherry tomatoes: Halved, they burst in the oven and add freshness and color.
• Mozzarella pearls: Small balls of fresh mozzarella that melt into creamy pockets of cheese.
• Salt and pepper: To taste.

Easy Ingredient Swaps

Chicken: This recipe works with boneless, skinless thighs or chicken breasts. Bone-in thighs can be used but will require longer searing and cook time.

Mozzarella: If you don’t have pearls, use larger mozzarella balls torn into pieces or cubed fresh mozzarella—both will melt nicely.

Thicker sauce option: If you prefer a thicker sauce, remove the chicken after baking, skim about ½ cup of the pan liquid, whisk in 3 teaspoons of cornstarch, return the thickened sauce to the pan and simmer briefly before returning the chicken.

Top Tips

• Don’t add cold chicken straight to a hot pan: Let the chicken sit at room temperature briefly so it won’t stick and will sear evenly.
• Season and marinate well: Allow at least one hour of marinating for the best flavor; overnight is ideal.
• Add mozzarella near the end: Top the chicken with mozzarella during the last 5–10 minutes of baking so it melts without overcooking.

If you enjoy cooking with chicken thighs, try other methods like stovetop searing, Dutch oven braises, cast-iron recipes, air fryer or grilled preparations. Chicken thighs are versatile and adapt well to many flavors and techniques.

Storage

Store leftovers in an airtight container in the refrigerator for 3–4 days. The sauce will thicken as it cools. To reheat, bake at 350°F (175°C) until heated through or until the chicken reaches an internal temperature of 165°F (74°C).

How to Serve this Dish

This balsamic chicken is excellent over wide pasta such as pappardelle, but any pasta will work. It’s also great over quinoa or rice, or paired with roasted vegetables like broccoli, Brussels sprouts, or a simple caprese salad. Finish with fresh basil and a drizzle of extra virgin olive oil for brightness.

Balsamic Chicken Thighs — Recipe

Prep time: about 1 hour (including marinating). Cook time: 20 minutes. Servings: 4.

Ingredients

Marinade

• ½ cup balsamic vinegar
• 2 tablespoons olive oil
• 2 teaspoons Dijon mustard
• 2 teaspoons brown sugar
• 1 teaspoon dried thyme

Chicken and sauce

• 1.5 lbs boneless skinless chicken thighs
• 1 tablespoon olive oil (for searing)
• ¼ cup dry white wine or broth
• 2 tablespoons tomato paste
• 10 oz cherry tomatoes, halved
• 8 oz mozzarella pearls
• ½ teaspoon sea salt
• ½ teaspoon ground black pepper
• Fresh basil leaves, for serving

Instructions

1. Combine all marinade ingredients in a large bowl or shallow dish and whisk until smooth. Submerge the chicken thighs in the marinade, cover, and refrigerate for at least 1 hour or up to overnight.
2. When ready to cook, remove the chicken from the refrigerator and let excess marinade drip off. Allow the chicken to come to near room temperature while you preheat the oven to 400°F (204°C).
3. Heat 1 tablespoon of olive oil in a large oven-safe skillet over high heat. When the oil is hot and shimmering, add the chicken thighs and sear for 3–4 minutes on one side until golden brown. Remove the chicken and set aside.
4. Deglaze the pan with the white wine or broth, scraping up any browned bits. Add the reserved marinade, tomato paste, salt, and pepper. Whisk to combine and bring to a boil over high heat to concentrate the flavors.
5. Add the halved cherry tomatoes to the sauce and toss briefly. Nestle the seared chicken thighs into the sauce, seared-side up.
6. Transfer the skillet to the preheated oven and bake for 15 minutes. Remove from the oven, scatter the mozzarella pearls over the chicken, and return to the oven for an additional 5–10 minutes until the mozzarella is melted and the chicken reaches an internal temperature of 165°F (74°C).
7. Remove from the oven, sprinkle with fresh basil, and serve immediately over pasta, grains, or with toasted bread.

Tips & Notes

• Bone-in thighs can be substituted but require longer searing and a slightly longer bake time—sear 3–4 minutes per side.
• Large mozzarella pieces or torn fresh mozzarella work well if pearls aren’t available.
• To thicken the sauce, remove the chicken, mix 3 teaspoons cornstarch into ½ cup of the pan liquid, return the mixture to the skillet, and simmer briefly until thickened before returning the chicken.
• Letting the chicken marinate longer improves flavor and tenderness.
