What is French Onion Baked Chicken?

French Onion Baked Chicken is a comforting, flavorful dish that combines two beloved food elements — caramelized onions and baked chicken — into a mouthwatering creation. It’s inspired by the classic French onion soup, which features sweet, caramelized onions cooked with herbs and broth, often topped with cheese. However, instead of a soup, you’re working with chicken breasts, sautéed onions, and cheese that melts beautifully in the oven.

This dish is perfect for those who love the flavors of French onion soup but want something a bit more substantial. The caramelized onions are slow-cooked to bring out their natural sweetness, and the chicken breasts are seasoned and seared for an extra layer of flavor. Then, everything is baked together, with cheese added to make each bite heavenly. Indulge in gourmet dining at home with our Filet Mignon with Shrimp and Lobster Cream

Step-by-Step Guide to Making French Onion Baked Chicken

This recipe is easy to follow and requires only a few simple steps to make a delicious dish that’s both comforting and satisfying. Here’s how you can prepare French Onion Baked Chicken from start to finish.

Step 1: Caramelize the Onions

Caramelizing onions is the key to bringing out their natural sweetness and creating the rich flavor base for this dish. Here’s how you do it:

1. Heat olive oil and butter: In a large 10-inch cast-iron skillet, heat 2 tablespoons of olive oil and 4 tablespoons of butter over medium heat. The combination of butter and oil gives the onions the perfect balance of richness and smoothness.
2. Cook the onions: Once the oil and butter are melted and hot, add the 2 sliced onions to the skillet. Stir them gently to coat them in the butter and oil. Cook the onions for about 10 minutes or until they soften and begin to turn translucent.
3. Add sugar and seasonings: Add 1 teaspoon of granulated sugar, ½ teaspoon of coarse sea salt, and 2-3 sprigs of fresh thyme (leaves removed) to the onions. Stir to combine. The sugar helps in the caramelization process, while the thyme infuses a lovely herby note to the onions. Add a bay leaf as well for an extra layer of flavor.
4. Caramelize: Keep cooking the onions for another 15-20 minutes, stirring occasionally. You want them to turn golden brown and develop a sweet, deep flavor. If the onions darken too quickly, add a splash of white wine or beef stock to deglaze the pan and prevent burning.
5. Add garlic: In the last 2 minutes of cooking, add 1-2 cloves of minced garlic to the onions. Let the garlic cook just until fragrant. Be sure not to let it burn.

Step 2: Prepare the Chicken

While the onions are caramelizing, it’s time to prepare the chicken.

1. Pound the chicken: Place 4 boneless, skinless chicken breasts on a cutting board and use a meat mallet or rolling pin to gently pound them to an even thickness of about ½ to ¾-inch. This ensures the chicken cooks evenly and stays tender.
2. Season the chicken: Pat the chicken dry with paper towels to remove any excess moisture. Season both sides of each breast with ½ teaspoon of black pepper. You can also add a pinch of salt if desired, though the caramelized onions will provide enough saltiness for the dish.
3. Sear the chicken: Heat the skillet to medium-high. Once the onions are done, remove them from the pan and set them aside. Add the chicken breasts to the skillet and sear for about 3-4 minutes per side, or until they’re golden brown. This step adds flavor and color to the chicken, but don’t worry — the chicken will finish cooking in the oven.

Step 3: Assemble the Dish

1. Preheat your oven: While the chicken is searing, preheat your oven to 350°F (175°C). You’ll be baking the chicken to ensure it reaches the perfect internal temperature and that the cheese melts beautifully.
2. Add the onions back: Once the chicken is seared, return the caramelized onions to the skillet, placing them on top of the chicken. Spread them evenly over the chicken to ensure each bite is flavorful.
3. Sprinkle flour: Sprinkle 1 tablespoon of all-purpose flour over the onions and chicken. Cook for 1-2 minutes to create a roux, which will help thicken the sauce.
4. Add wine and broth: Pour in ½ cup of dry white wine (or extra beef stock if you prefer to skip the wine) and simmer for 2-3 minutes to allow the flavors to meld and the liquid to reduce slightly. Then add 1 cup of beef stock to the skillet and let the mixture simmer until it thickens.
5. Top with cheese: Once the sauce has thickened slightly, it’s time to add the cheese! Sprinkle 1 cup of grated provolone cheese and 1 cup of grated Swiss cheese evenly over the chicken breasts. These cheeses melt perfectly and provide a rich, creamy texture that pairs wonderfully with the caramelized onions.

Step 4: Bake the Chicken

1. Bake: Transfer the skillet to your preheated oven and bake for 20-25 minutes, or until the cheese is melted, bubbly, and golden brown, and the chicken reaches an internal temperature of 165°F (75°C).
2. Garnish and serve: Once the dish is done, remove it from the oven and let it rest for a few minutes. Garnish with fresh thyme before serving for a pop of color and freshness.

Tips for the Perfect French Onion Baked Chicken

To make sure your French Onion Baked Chicken turns out perfectly every time, follow these helpful tips:

• Use a cast-iron skillet: A cast-iron skillet helps distribute heat evenly, which is crucial for searing the chicken and caramelizing the onions.
• Be patient with the onions: Don’t rush the caramelizing process. The slower you cook them, the sweeter and more flavorful they’ll become. This step is key to achieving that rich, savory taste.
• Sear the chicken well: Don’t skip the searing step. It adds flavor and ensures a nice golden crust on the chicken.
• Use quality cheese: The cheese is a major part of this dish, so use good-quality provolone and Swiss for the best flavor and meltability.
• Substitute if necessary: If you prefer chicken thighs over breasts, feel free to use them. Thighs are juicier and work well in this dish. You can also experiment with different cheeses like Gruyère or cheddar.

Frequently Asked Questions (FAQ)

1. Can I use bone-in chicken for this recipe?
While this recipe calls for boneless, skinless chicken breasts, you can certainly use bone-in chicken if you prefer. Just be sure to adjust the cooking time since bone-in chicken takes longer to cook through.

2. What’s the best wine to use for French Onion Baked Chicken?
A dry white wine like Sauvignon Blanc works great, but you can also use a Chardonnay or any other dry white wine you enjoy. If you don’t drink wine, feel free to substitute with extra beef stock.

3. Can I make this dish ahead of time?
Yes, you can make the caramelized onions and sauce ahead of time. Just store them separately in the fridge and assemble the dish when you’re ready. You can even bake it the day before and reheat it in the oven before serving.

4. Can I freeze French Onion Baked Chicken?
Yes, this dish freezes well. Let it cool completely, then store it in an airtight container. When you’re ready to eat, thaw it overnight in the fridge and reheat in the oven at 350°F until heated through.
