Keeping French Onion Chicken Bake Fresh

• Freeze individual portions wrapped tightly in plastic wrap, then placed inside freezer bags, so your chicken remains tasty for up to two months.

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.
