This Low Carb Pesto Caprese Chicken is a skillet-seared chicken breast topped with herby pesto, melted fresh mozzarella, juicy tomatoes, and a garlicky balsamic reduction.
Slice each chicken breast lengthwise in half to make 4 even cutlets. Season both sides with salt and pepper.
Heat olive oil and butter in an oven-safe skillet over medium-high heat. Sear chicken 4 to 5 minutes per side until golden and cooked through.
While chicken cooks, combine balsamic vinegar and minced garlic in a small saucepan over medium-low heat. Simmer 8 to 10 minutes until reduced to a thick glaze.
Leave the chicken in the skillet. Brush each cutlet with balsamic reduction, spread pesto on top, add a basil leaf, then lay a slice of fresh mozzarella over each one.
Transfer the skillet to the oven and broil for 2 to 3 minutes until the mozzarella is melted and bubbling.
Remove from oven and top each cutlet with a fresh tomato slice.
Drizzle with remaining balsamic glaze, garnish with fresh basil and serve immediately.
