Key Ingredients for French Onion Chicken Bake
- 4 boneless, skinless chicken breasts
- 2 large onions, thinly sliced
- 2 tablespoons olive oil
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon thyme (fresh or dried)
- 1 cup beef or chicken broth (or low-sodium)
- 1 cup cream (or half-and-half)
- 1 cup shredded Swiss cheese
- Salt and pepper to taste
- Optional: fresh parsley for garnish
Step-by-Step Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C).
- Sauté the Onions: In a large skillet, heat the olive oil over medium heat. Add the sliced onions and sauté for about 10-15 minutes, or until they become soft and caramelized. Stir occasionally to prevent burning.
- Prepare the Chicken: While the onions are cooking, season chicken breasts with garlic powder, onion powder, thyme, salt, and pepper on both sides.
- Add the Broth and Cream: Once the onions are caramelized, add the broth and cream to the skillet. Stir well to combine, then bring to a gentle simmer.
- Combine Chicken and Sauce: Place the seasoned chicken breasts in a baking dish and pour the onion sauce over them, making sure they’re well-covered.
- Bake: Carefully transfer the baking dish to the preheated oven and bake for 25-30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
- Add the Cheese: Remove the dish from the oven and sprinkle the shredded Swiss cheese on top. Return it to the oven and bake for an additional 5-10 minutes or until the cheese is melted and bubbly.
- Garnish and Serve: Once ready, garnish with fresh parsley if desired, and serve warm.
What to Serve French Onion Chicken Bake With
To round out your meal, consider serving this French Onion Chicken Bake with a crisp green salad, a side of roasted vegetables, or some fluffy rice or mashed potatoes to soak up all that delicious sauce. Want to keep it light? Pairing it with some steamed broccoli or asparagus adds a nice touch of color and flavor.
Top Tips for Perfecting French Onion Chicken Bake
- Use Fresh Ingredients: Fresh herbs can elevate the flavor, so if you have thyme or parsley available, don’t hesitate to use them.
- Adjust the Cheese: If Swiss isn’t your favorite, feel free to experiment with other cheeses like Gruyère or mozzarella for a different taste.
- Cook the Onions Longer: The more caramelized the onions, the richer the flavor—so don’t rush this step!
Storing and Reheating Tips
If you have leftovers (which are great for meal prep!), simply store the French Onion Chicken Bake in an airtight container in the refrigerator for up to three days. To reheat, place in an oven-safe dish and warm in the oven at 350°F (175°C) until heated through. Alternatively, you can microwave it, but the oven will help keep that nice cheesy texture!
