This healthy chicken skillet is a vibrant one-pan meal that brings together tender chicken, juicy tomatoes, fresh basil, and melty mozzarella with a touch of balsamic sweetness. Inspired by classic Caprese salad, this balanced, weeknight-friendly recipe is satisfying without being complicated.
Make the Balsamic Glaze: In a small saucepan, mix ½ cup of the balsamic vinegar with 1 tablespoon of the honey. Warm over medium-low heat and simmer gently, stirring now and then, until it reduces and thickens—about 15 minutes. Set aside once done.
Prep the Chicken: While the glaze simmers, place the chicken breasts between two sheets of plastic wrap. Pound evenly to ½-inch thickness. Season both sides with ¾ teaspoon salt and ¼ teaspoon pepper.
Sear the Chicken: Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Once shimmering, add chicken breast pieces smooth side down. Sear for 4 minutes without moving, flip, then cook another 3 minutes. Check that the internal temperature hits 165°F. Transfer to a plate and tent loosely to keep warm.
Cook Vegetables: Reduce heat to medium and add the remaining tablespoon of olive oil. Stir in the diced onion and cook for 3 minutes, scraping up any browned bits from the pan. Stir in the minced garlic and cook another 30 seconds until aromatic. Add the sliced tomatoes, thyme, remaining 1 tablespoon balsamic vinegar, 1 teaspoon honey, ½ teaspoon salt, and ¼ teaspoon pepper. Stir and cook for about 2 minutes until tomatoes begin to soften.
Finish the Dish: Nestle the cooked chicken breasts back into the pan, spooning tomatoes around them. Scatter the mozzarella over everything. Cover the pan, turn off the heat, and let it sit for 1 to 2 minutes to melt the cheese. Uncover, drizzle the balsamic glaze over the top, and sprinkle with fresh basil. Serve immediately.
Notes
Leftover Idea: Make a Caprese Chicken and Arugula Salad—chop leftover chicken and toss with extra tomatoes, mozzarella, and arugula. Drizzle with olive oil and a touch of balsamic vinegar. Season to taste.Shortcut Tip: You can use store-bought balsamic glaze to save time. Just skip the reduction step and drizzle at the end.Cheese Swap: If you can't find mozzarella pearls, cube block mozzarella or even use shredded part-skim.
