This Easy Caprese Chicken Skillet is a quick, one-pan Italian-inspired dinner that delivers restaurant-quality flavor in just 30 minutes. Juicy golden-seared chicken breasts are nestled into a garlicky burst-tomato sauce, topped with creamy melted fresh mozzarella, fragrant fresh basil, and a drizzle of tangy balsamic glaze. It's naturally low-carb, gluten-free, and packed with protein — elegant enough for guests, easy enough for any weeknight.
Cover each chicken breast with plastic wrap and pound to an even 3/4-inch thickness using a meat mallet or rolling pin. Pat completely dry with paper towels, then season generously on both sides with the garlic powder, Italian seasoning, onion powder, salt, and pepper.
Heat olive oil in a large oven-safe skillet over medium-high heat until shimmering. Add chicken breasts and cook undisturbed for 5–6 minutes per side, until deeply golden and the internal temperature reaches 160°F (71°C). Transfer to a plate and tent loosely with foil to rest.
Reduce heat to medium. Add minced garlic to the same skillet and stir for 30–45 seconds until fragrant, then add the cherry tomatoes with a pinch of salt and pepper. Cook for 3–4 minutes, stirring occasionally, until the tomatoes soften and begin to release their juices. Stir in butter (if using) until melted.
Nestle the rested chicken breasts back into the skillet over the tomato mixture and spoon pan juices over each breast. Lay 2–3 mozzarella slices on top of each chicken breast, then cover with a lid (or broil on high for 2–3 minutes) until the cheese is fully melted and bubbly.
Remove from heat and scatter fresh basil leaves over the top. Drizzle balsamic glaze over everything, add red pepper flakes if desired, and serve immediately with extra tomato pan sauce spooned over each portion.
Notes
Pound the chicken evenly: Getting each breast to a uniform 3/4-inch thickness is the single best thing you can do for juicy, evenly cooked chicken.
Dry the chicken thoroughly: Patting with paper towels removes surface moisture, which is essential for achieving a deep golden sear rather than a gray steam.
Don't move the chicken while searing: Let it sit undisturbed until it releases naturally from the pan — that's when you know the crust has formed.
Use fresh mozzarella packed in water: Pre-shredded or low-moisture mozzarella won't melt as beautifully or taste as good. Fresh is worth it here.
Add basil off the heat: Fresh basil wilts and darkens quickly. Add it after removing the pan from the stove to keep its bright color and flavor.
Chicken thigh swap: Boneless, skinless chicken thighs work great and are more forgiving — just add 2–3 extra minutes of cook time and verify 165°F internal temp.
Make it creamy: Stir 1/4 cup heavy cream into the tomato base after the garlic step for a rich, creamy Caprese sauce variation.
Storage: Refrigerate leftovers in an airtight container for up to 3 days. Store fresh basil and balsamic glaze separately and add fresh after reheating.
Freezing: Freeze the chicken and tomato sauce (without mozzarella and basil) for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating: Warm in a covered skillet over medium-low with a splash of water or chicken broth, then lay fresh mozzarella on top and heat until melted before serving.
