How to Make Low Carb Caprese Chicken Bake
-
Preheat the oven: Start by setting your oven to 425°F. Place a cast-iron skillet inside to heat up and create that perfect roast for your chicken.
-
Prep the chicken: Pat the boneless skinless chicken breasts dry with a paper towel. Drizzle 1 tablespoon of olive oil over them, then season with 1 teaspoon of sea salt, dried oregano, and minced garlic. Let them sit while you prepare the vegetables.
-
Arrange vegetables: Carefully remove the hot skillet from the oven. Add the remaining olive oil and toss in the tomatoes and thinly sliced red onions. Sprinkle with 1.5 teaspoons of sea salt and give everything a good toss to coat.
-
Add the chicken: Place the seasoned chicken breasts on top of the vibrant veggies in the skillet. Bake in the preheated oven for about 15 minutes, allowing the flavors to meld together.
-
Top with mozzarella: After 15 minutes, pull the skillet out and add one slice of mozzarella cheese on top of each chicken breast. Return to the oven for an additional 5-7 minutes until the cheese is melted and bubbly, and the chicken reaches an internal temperature of 165°F.
-
Make the balsamic reduction: While the chicken finishes baking, simmer the balsamic vinegar in a small pot over medium heat until it reduces by half and becomes syrupy. This will take about 5-8 minutes.
-
Serve with flair: Once everything is done, drizzle the reduction over the chicken and top with freshly chopped basil for that beautiful finishing touch. Serve and enjoy!
Optional: Add a sprinkle of red pepper flakes for a hint of spice.
