- 4 chicken breasts (boneless and skinless): The lean protein base that soaks up all the wonderful flavors.
- 4 tbsp olive oil (divided): Delivers richness and helps create a golden sear and tender roast.
- 2 ½ tbsp sea salt (divided): Enhances all flavors while balancing the dish perfectly.
- ¾ tsp dried oregano: Offers a subtle herbaceous note reminiscent of classic Italian cooking.
- 4 cloves garlic (minced): Infuses the chicken with aromatic depth and warmth.
- 8 oz mozzarella ball (sliced into 8 slices): Melts beautifully to gooey, creamy perfection on top.
- ½ cup balsamic vinegar: Reduced to make a luscious, tangy glaze that ties all elements together.
- 10 leaves fresh basil (chopped for garnish): The fresh, peppery finish that brightens every bite.
How to Make Low Carb Caprese Chicken Bake Recipe
Step 1: Preheat and Prepare Your Pan
Start by preheating your oven to 425 F. Place a cast iron pan inside the oven to preheat as well, which will give your chicken a nice sear and help develop those irresistible flavors. If you don’t have a cast iron pan, any oven-safe baking dish will work, just keep in mind that the sear won’t be quite the same but the result will still be delicious.
Step 2: Season the Chicken
While the oven and pan heat up, drizzle 1 tablespoon of olive oil over the chicken breasts. Sprinkle 1 teaspoon of sea salt and the dried oregano over each piece. Add the minced garlic and rub all these seasonings thoroughly into the chicken; this step ensures every bite bursts with herby, garlicky goodness. Set the seasoned chicken aside for just a moment while you get the rest ready.
Step 3: Prepare the Veggie Base
Remove your hot pan carefully from the oven and add the remaining 3 tablespoons of olive oil. Toss in the tomatoes and thinly sliced red onions, seasoning them with 1 ½ teaspoon of sea salt. Stir everything together to coat evenly, then arrange the seasoned chicken breasts atop this vibrant bed of tomatoes and onions, making sure they get cozy and ready for roasting.
Step 4: First Bake and Add Cheese
Pop the pan back into the oven for 15 minutes to let the chicken start cooking through and the veggies begin to release their juices, melding lovely flavors. After 15 minutes, pull the pan out and layer the mozzarella slices evenly over each chicken breast. Return to the oven and bake another 5 to 7 minutes until the cheese melts perfectly and the chicken reaches an internal temperature of 165 F—juicy and fully cooked.
Step 5: Reduce the Balsamic
While the chicken bakes, pour the balsamic vinegar into a small nonstick pot and simmer over medium-low heat until it reduces by half and thickens into a glossy syrup. This balsamic reduction adds a sweet, tangy contrast to the creamy cheese and roasted chicken. If you’re short on time, feel free to use a store-bought balsamic glaze as a shortcut.
Step 6: Finish and Garnish
Once the chicken is out of the oven, drizzle the balsamic reduction generously over the top. Sprinkle the chopped fresh basil leaves as a final flourish—this bright, fresh herb lifts the dish and ties all the flavors together. Serve your Low Carb Caprese Chicken Bake Recipe while it’s warm and melty for the ultimate comforting experience.
How to Serve Low Carb Caprese Chicken Bake Recipe
Garnishes
Fresh basil is essential, but you can also add some freshly cracked black pepper or sprinkle a few pine nuts for an added nutty crunch. A light extra drizzle of good quality olive oil right before serving will bring a beautiful finish and shine.
Side Dishes
This dish stands well on its own thanks to the hearty chicken and flavorful veggies, but for a more complete meal, serve it alongside simple steamed greens, a crisp mixed green salad with lemon vinaigrette, or even cauliflower rice if you want to keep it low carb and filling.
Creative Ways to Present
For a dinner party, consider serving this Low Carb Caprese Chicken Bake Recipe on a rustic wooden board with extra fresh basil and balsamic drizzle on the side, accompanied by toasted garlic breadsticks or zucchini ribbons tossed in olive oil and herbs for an elegant, colorful plating.
Make Ahead and Storage
Storing Leftovers
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. The flavors actually meld more during storage, making the reheated dish equally delicious.
Freezing
If you want to freeze leftovers, remove the fresh basil garnish first. Wrap portions tightly in freezer-safe containers or bags, and they’ll keep well for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheating
To reheat, place the chicken bake in an oven-safe dish and warm it at 350 F until heated through, about 15-20 minutes. This method keeps the cheese from overcooking and maintains the juiciness of the chicken better than microwaving.
FAQs
Can I use other types of cheese instead of mozzarella?
Absolutely! Fresh mozzarella is classic for a Caprese style, but sliced provolone or even burrata if you want extra creaminess can work well. Just pick a cheese that melts beautifully and has a mild flavor.
Is this recipe gluten-free?
Yes, this Low Carb Caprese Chicken Bake Recipe is naturally gluten-free, making it a fantastic choice for those avoiding gluten. Just ensure your balsamic vinegar or glaze does not contain any added gluten ingredients.
Can I make this recipe dairy-free?
You can! Simply swap the mozzarella for a dairy-free cheese alternative that melts well, or even omit cheese altogether and add extra fresh basil and a splash of olive oil for richness.
What can I substitute for fresh basil if I don’t have any?
While fresh basil is key for that classic Caprese flavor, fresh parsley or even oregano can be used in a pinch. They won’t give the exact same taste but will maintain a fresh herbaceous note.
How do I know when the chicken is fully cooked?
The safest way is to check that the chicken’s internal temperature reaches 165 F using a meat thermometer. The juices should run clear, and the cheese should be melted and slightly golden.
Final Thoughts
This Low Carb Caprese Chicken Bake Recipe is one of those rare meals that feels indulgent yet fits perfectly into a mindful eating plan.

Ingredients
Chicken and Seasoning
- 4 boneless, skinless chicken breasts
- 4 cloves garlic, minced
- 4 tbsp olive oil, divided
- 2 ½ tbsp sea salt, divided
- ¾ tsp dried oregano
Vegetables
- 3 cups tomatoes on the vine or cherry tomatoes
- 1 small red onion, thinly sliced
Toppings and Garnish
- 8 oz mozzarella ball, sliced into 8 slices
- 10 fresh basil leaves, chopped for garnish
- ½ cup balsamic vinegar (for reduction)
Instructions
- Preheat Oven and Pan: Preheat your oven to 425°F (220°C). Place a cast iron pan inside the oven to preheat as well. If you don’t have a cast iron pan, a baking dish will work just fine.
- Season Chicken: Drizzle 1 tablespoon of olive oil onto the chicken breasts. Sprinkle with 1 teaspoon of sea salt and the dried oregano. Add the minced garlic and rub all the seasonings thoroughly over each chicken breast. Set aside to marinate briefly.
- Prepare Vegetables and Arrange Chicken: Carefully remove the hot pan from the oven. Add the remaining 3 tablespoons of olive oil to the pan along with the tomatoes and sliced red onions. Season these with 1 ½ teaspoons of sea salt and stir to combine. Arrange the seasoned chicken breasts on top of the tomato and onion mixture.
- First Bake: Place the pan in the oven and bake for 15 minutes. This allows the chicken to start cooking and the vegetables to roast.
- Add Mozzarella and Continue Baking: Remove the pan from the oven and place the mozzarella slices evenly over each chicken breast. Return to the oven and bake for an additional 5 to 7 minutes until the cheese melts and the chicken reaches an internal temperature of 165°F (74°C).
- Prepare Balsamic Reduction: While the chicken is baking, pour the balsamic vinegar into a small nonstick pot and simmer over medium-low heat until the vinegar reduces by half and thickens into a syrupy consistency. This should take several minutes. Alternatively, you can use pre-made balsamic glaze.
- Finish and Serve: Remove the skillet from the oven. Drizzle the balsamic reduction over the chicken and vegetables. Garnish with chopped fresh basil leaves. Serve the dish hot for best flavor and enjoyment.
Notes
- If you don’t have a cast iron pan, use any oven-safe baking dish.
