Ingredients for French Onion Chicken Bake

• 4 boneless, skinless chicken breasts
• 3 large yellow onions, thinly sliced
• 2 tbsp olive oil
• 1 tbsp butter
• 2 tsp fresh thyme leaves (or 1 tsp dried thyme)
• 1/2 cup (120ml) beef broth
• 1 tbsp balsamic vinegar
• 1/2 tsp salt (adjust to taste)
• 1/4 tsp black pepper
• 1 cup (100g) shredded Gruyère cheese (or Swiss cheese)
• 1/4 cup (25g) grated Parmesan cheese
• Fresh parsley, chopped (optional, for garnish)

Kitchen Equipment You’ll Need

• Large skillet
• Baking dish (9×13-inch)
• Tongs (for handling chicken)
• Wooden spoon (for stirring onions)
• Aluminum foil (for covering while baking)

Step-by-Step Instructions

1. Preheat the Oven

Preheat your oven to 375°F (190°C) and lightly grease a baking dish with cooking spray or a small amount of olive oil.

2. Caramelize the Onions

In a large skillet, heat the olive oil and butter over medium heat. Add the sliced onions and cook, stirring frequently, for 15-20 minutes, or until they’re golden brown and caramelized. Stir in the thyme, balsamic vinegar, salt, and pepper. Remove from heat and set aside.

3. Sear the Chicken

Season the chicken breasts with salt and pepper. In the same skillet, add a drizzle of olive oil and sear the chicken over medium-high heat for 2-3 minutes per side, until lightly golden. Transfer the chicken to the prepared baking dish.

4. Layer the Onions and Cheese

Spread the caramelized onions evenly over the chicken breasts. Pour the beef broth around the chicken (not directly on top). Sprinkle the Gruyère and Parmesan cheeses over the onions.

5. Bake the Chicken

Cover the baking dish with aluminum foil and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the chicken is cooked through (internal temperature of 165°F or 74°C) and the cheese is bubbly and golden.

6. Garnish and Serve

Remove the dish from the oven and let it rest for 5 minutes. Garnish with fresh parsley if desired, and serve warm.

Tips for Perfect French Onion Chicken

• Caramelize Slowly: Don’t rush the onions; cooking them low and slow develops their rich, sweet flavor.
• Choose Quality Cheese: Gruyère is the best choice for its nutty, melty quality, but Swiss or provolone work well too.
• Avoid Overcooking Chicken: Use a meat thermometer to ensure the chicken is perfectly juicy and not overdone.
• Deglaze the Skillet: Scrape up the browned bits in the skillet with the broth for extra flavor.

Recipe Variations and Additions

1. Add Mushrooms: Sauté sliced mushrooms with the onions for an earthy twist.
2. Try Different Cheese: Use mozzarella or a sharp cheddar for a unique flavor.
3. Make It Creamy: Add a splash of heavy cream to the broth for a creamy sauce.
4. Use Chicken Thighs: Swap chicken breasts for boneless, skinless thighs for extra richness.

How to Serve French Onion Chicken Bake

• With Starches: Pair with mashed potatoes, rice, or egg noodles to soak up the flavorful broth.
• With Vegetables: Serve alongside roasted asparagus, green beans, or a fresh side salad.
• With Bread: Crusty French bread is perfect for sopping up the delicious sauce.

Storing and Reheating Leftovers

• Storage: Place leftovers in an airtight container and refrigerate for up to 3 days.
• Reheating: Warm in the oven at 350°F (175°C) for 15-20 minutes or microwave in 30-second intervals until heated through.
• Freezing: Freeze in an airtight container for up to 2 months. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions (FAQs)

1. Can I make this dish ahead of time?

2. What if I don’t have beef broth?
You can use chicken broth or vegetable broth as a substitute, though beef broth provides the richest flavor.

3. Can I caramelize the onions faster?
Caramelizing onions takes time, but you can add a pinch of sugar to speed up the process slightly.

4. How do I know when the chicken is fully cooked?
Use a meat thermometer to check that the chicken has reached an internal temperature of 165°F (74°C).
