Ingredients

Scale

Main Ingredients:

  • 4 Boneless Chicken Breasts
  • 4 Sliced Onions
  • 1 cup Shredded Mozzarella
  • ½ cup Grated Parmesan

Supporting Ingredients:

  • 4 Tablespoons Unsalted Butter
  • ⅔ cup Beef Broth
  • 4 Garlic Cloves
  • 2 Tablespoons Aged Balsamic Vinegar

Seasonings:

  • 1 Teaspoon Fresh Thyme
  • ½ Teaspoon Sea Salt
  • ½ Teaspoon Black Pepper

Instructions

  1. Prepare your oven by heating it to 400°F and lightly coating a 9×13-inch baking dish with cooking spray.
  2. Melt 4 tbsp unsalted butter in a large skillet over medium-high heat. Add 4 sliced onions and cook for 5 minutes, stirring occasionally.
  3. Reduce skillet heat to medium. Sprinkle in 4 finely chopped garlic cloves, ½ tsp black pepper, and 1 tsp fresh thyme. Stir for 1 minute.
  4. Pour ⅔ cup beef broth and 2 tbsp balsamic vinegar into the skillet. Simmer until onions transform into a thick, jammy consistency, about 10 minutes.
  5. Spread one-third of the caramelized onions across the bottom of your prepared baking dish.
  6. Arrange 4 chicken breasts over the onion layer. Dust with ½ tsp sea salt.
  7. Cover chicken with remaining caramelized onions, then generously top with 1 cup mozzarella and ½ cup Parmesan cheese.
  8. Bake at 400°F for 30 minutes, ensuring your chicken reaches an internal temperature of 165°F.

Notes

  • Caramelize onions slowly to develop deep, rich flavor without burning them by keeping the heat moderate and stirring frequently.
  • Pat chicken breasts dry before seasoning to help them brown nicely and prevent excess moisture during baking.
  • For a low-carb version, substitute beef broth with chicken broth and ensure all ingredients align with dietary restrictions.
  • Swap cheeses based on preference – gruyere works wonderfully as an alternative to mozzarella for a more traditional French onion profile.
