Ingredients
  

  • 4 boneless, skinless chicken breasts (about 6–8 oz each)
  • 1 teaspoon kosher salt, plus more to taste
  • 1/2 teaspoon black pepper
  • 1 teaspoon garlic powder
  • 1 teaspoon Italian seasoning (or dried oregano)
  • 2 tablespoons olive oil, divided
  • 1 tablespoon butter (optional, for extra browning and flavor)
  • 8 ounces fresh mozzarella, sliced into 8 rounds
  • 2 medium tomatoes, ripe but firm, sliced into 8 rounds
  • 1/3 cup fresh basil leaves, torn or chiffonade
  • 2 tablespoons balsamic vinegar (or 1 tablespoon balsamic reduction; see note below)
  • 1 teaspoon Dijon mustard (for the pan sauce)
  • 1–2 teaspoons erythritol or allulose (optional, to balance the vinegar)
  • Flaky sea salt, to finish (optional)

Method
 

  1. Prep the chicken: Pat the chicken breasts dry. If they’re very thick, slice horizontally to create cutlets or pound to even thickness (about 3/4 inch). Season both sides with salt, pepper, garlic powder, and Italian seasoning.
  2. Heat the pan: Set a large skillet over medium-high heat. Add 1 tablespoon olive oil. When it shimmers, add the butter if using.
  3. Sear the chicken: Place chicken in the pan without crowding. Sear 4–6 minutes per side, until golden with an internal temperature of 160°F. Adjust heat to prevent burning.
  4. Top with Caprese: Lower heat to medium-low. Place 2 slices of tomato on each breast, then 2 slices of mozzarella. Cover the pan for 1–2 minutes until the cheese softens but doesn’t fully melt into a puddle.
  5. Rest and move: Transfer chicken to a plate and tent loosely with foil to rest. Keep the pan on the stove for the sauce.
  6. Make a quick pan sauce: Add remaining 1 tablespoon olive oil to the skillet. Pour in the balsamic vinegar, add Dijon, and whisk, scraping up brown bits. Simmer 1–2 minutes. Taste and add a pinch of sweetener if you want a smoother, less tangy finish. Season with salt and pepper.
  7. Finish with basil: Spoon a little sauce over each chicken breast. Scatter fresh basil over the top. Sprinkle with flaky sea salt if you like a little crunch.
  8. Serve: Plate with a side of sautéed zucchini, garlicky spinach, or a simple arugula salad to keep things low-carb and balanced.
