Boneless chicken thighs with sweet and sour sauce in a skillet.

Andi is holding a skillet with boneless chicken thighs in a sweet and sour sauce.

Note From Andi:

This is one of those dependable dinners I make when I need something simple but still comforting and homemade.

Over the years I've tried a lot of sweet and sour chicken variations, but using boneless chicken thighs keeps the recipe easier while making the meat incredibly juicy.

The key step is searing the chicken first in a hot skillet. That golden crust builds flavor and helps the sweet and sour sauce cling to the chicken as it bakes.

By the time it comes out of the oven, the sauce is thick, glossy, and slightly caramelized around the edges of the pan. It's a simple recipe, but it works every single time.

The ingredients for sweet and sour boneless chicken are in small individual bowls.

Recipe Ingredients 👇👇

For The Chicken:

2 lbs boneless skinless chicken thighs (about 6-8 pieces) - naturally juicy and tender
Salt and black pepper, to taste
2 tsp cornstarch
2 Tbsp salted butter, divided - used for searing and building flavor in the skillet

Sweet and Sour Sauce:

½ cup lemon juice - or white vinegar for the tangy base
¾ cup brown sugar - balances the acidity with sweetness
½ cup tomato sauce - adds body and classic sweet-and-sour flavor
1 Tbsp soy sauce
1 tsp garlic powder
1 tsp cornstarch - goes into a slurry (with water) and gets stirred into the sauce

Step-By-Step Instructions 👇👇

Boneless chicken thighs are seasoned with salt and pepper, then sprinkled with cornstarch.

STEP 1: Prep the Chicken

Preheat the oven to 400°F. Pat 2 lbs boneless skinless chicken thighs dry and season both sides with salt and black pepper, then sprinkle 2 tsp cornstarch over the chicken and rub lightly to coat.

Lemon juice, brown sugar, tomato sauce, soy sauce, and garlic powder are in a small bowl and then the ingredients are mixed with a whisk to make a sauce.

STEP 2: Make the Sauce

In a bowl, whisk together ½ cup lemon juice, ¾ cup brown sugar, ½ cup tomato sauce, 1 Tbsp soy sauce, and 1 tsp garlic powder until smooth.

In a separate small bowl, stir 1 tsp cornstarch with 1 Tbsp water to make a slurry, then whisk the slurry into the sauce mixture.

The boneless chicken thighs are seared in a pan on both sides, then transferred to a plate.

STEP 3: Sear the Chicken

Heat 1 Tbsp salted butter in an oven-safe skillet over medium-high heat. Add the chicken thighs and sear for 4-5 minutes per side until deeply golden and lightly crisp. Transfer the chicken to a plate.

A four-image collage of the sauce is added to the skillet and warmed until slightly thickened, then the chicken thighs are added to the skillet, and then the chicken thighs are fully cooked in the skillet, and the sauce is thicker.

STEP 4: Heat the Sauce

Reduce heat to low and pour the prepared sweet and sour sauce into the skillet. Warm gently for 1-2 minutes until slightly thickened.

STEP 5: Bake Until Sticky and Tender

Return the chicken thighs to the skillet and spoon sauce over the top. Transfer to the oven and bake for 20-25 minutes, flipping halfway through, until the chicken reaches an internal temperature of 165°F and the sauce has thickened.

Spoon extra sauce over the chicken and garnish with fresh parsley before serving if desired.

Recipe Tips

Pat the chicken dry first so it sears instead of steaming.
Don't skip the sear, which builds flavor and helps the sauce cling.
Bake until 165°F internal temperature for safe, juicy chicken.
Let the sauce bubble and thicken in the oven for best texture.
Spoon sauce over before serving to keep the chicken glossy and flavorful.

Variations and Substitutions

Use boneless chicken breasts instead of thighs, reducing bake time slightly.
Add pineapple chunks or bell peppers for classic sweet-and-sour flavor.
Swap honey for part of the brown sugar for a different sweetness.
Use rice vinegar instead of lemon juice for a milder tang.
Sprinkle with green onions or sesame seeds before serving.

What To Serve With

These sweet and sour chicken thighs pair perfectly with garlic butter rice, fried rice, or simple noodles to soak up the extra sauce. Add a quick vegetable side like roasted broccoli, sautéed green beans, or stir-fried peppers for a complete family dinner.

Leftovers are delicious tucked into rice bowls or wraps the next day. I like to meal prep this recipe for my salads at lunch throughout the week.

Storage and Reheating

Fridge: Store in an airtight container for up to 4 days.
Freezer: Freeze cooked chicken and sauce for up to 2 months.
