French Onion Soup: What It Is and Why We Did This Version
French onion soup is a classic soup originating from France, known for its rich, caramelized onion flavor and topped with a slice of baguette and melted Gruyère cheese. The combination of beef broth, white wine, and slow-cooked onions creates a depth of flavor that’s hard to resist.
This French onion soup chicken recipe takes all the best elements of the classic soup and transforms them into a hearty, satisfying chicken dish. The main reason for this adaptation is to create a complete meal that includes protein, making it not just a soup but a wholesome dinner that’s perfect for the whole family. Plus, it’s a great way to use simple ingredients and create something truly special.
Ingredients Used
For this delicious French Onion Chicken recipe, you’ll need:
- 4 boneless skinless chicken breasts: These provide a tender and juicy base for the dish.
- 1 tablespoon butter and 1 tablespoon olive oil: These fats help caramelize the onions and brown the chicken. We are using butter for its flavor and oil for its ability to reach higher temperatures. Without the oil, the butter would burn and ruin our dish.
- 3 yellow onions: Yellow onions are perfect for caramelizing due to their sweet flavor.
- 1 tablespoon sugar: Helps to enhance the caramelization process.
- ¼ cup white wine: Adds depth and complexity to the onion mixture.
- 2 teaspoons corn flour: Used to thicken the caramelized onion sauce. You could change it for flour but this option makes the dish gluten-free.
- 1 cup chicken broth: Creates a rich and savory sauce.
- 1 cup shredded Gruyère or Swiss cheese: Adds a melty cheese topping that’s essential for French onion soup recipes.
- Salt and pepper: To season the chicken and onions.
- Fresh thyme (optional): For added flavor and aroma.
How to Make French Onion Soup Chicken
Step 1: Prepare the Chicken
Season the chicken breasts with salt and black pepper on both sides. In a large oven-safe skillet or dutch oven, heat the butter and olive oil over medium-high heat. Add the chicken breasts and cook for about 4-5 minutes on each side, until browned. Set aside.
Step 2: Caramelize the Onions
Peel the onions, trim the ends, and cut them in half. Slice them lengthwise. In the same skillet (don’t wash it, the brown bits at the bottom of the pan are delicious), add the sliced onions. Add salt, pepper, and sugar. Cook over medium heat, stirring occasionally, for about 10 minutes until they start to caramelize. Be patient and let them cook slowly to develop their sweetness.
Step 3: Deglaze and Cook the Onions
Add the white wine to the onions and let it cook for a couple of minutes to let the alcohol and acidity evaporate. Cover the skillet and cook for 15 minutes until the onions are golden brown and caramelized.
Step 4: Make the Sauce
Sprinkle the corn flour over the onions, then add the chicken broth and thyme. Let it simmer, stirring constantly, for a few minutes until the sauce has thickened slightly. Preheat your oven to 375°F (190°C)
Step 5: Assemble and Bake
Add the chicken breasts back to the skillet, nestling them into the caramelized onions. Sprinkle a generous amount of shredded cheese over the top of each chicken breast. Transfer the skillet to the preheated oven and bake for about 15-20 minutes, or until the chicken is cooked through and the cheese is melted and bubbly.
Advantages of an Oven-Safe Dish
We know how fancy a French table can be, but sometimes the elegance lies in simplicity. Every French household has a “cocotte,” also called a Dutch Oven. These enameled cast iron pots are so easy for roasting, baking, slow cooking, etc. Until today, it is still a traditional wedding gift! And for my friends reading this article, my birthday is coming up and my favorite color would be sage. Just saying…
Using an oven-safe dish, like a Le Creuset or Lodge Dutch Oven ensures that you can easily transfer your dish from the stovetop to the oven without needing to switch pans.
This not only saves time but also helps in retaining all those flavorful bits from the caramelized onions and browned chicken. These dishes are usually aesthetically pleasing, so you can also bring them directly from the oven to the table, making it a 3-in-1 solution with much less washing up!
Oven-safe skillets or Dutch ovens are particularly great because they are made of high-quality materials that distribute heat evenly, ensuring your chicken cooks perfectly every time. Investing in a good oven-safe dish is a good choice for any home cook who loves making one-pot meals.
Tips on How to Make an Onion Soup Chicken Casserole
- Can I use different types of onions?
Absolutely! While yellow onions are traditional for caramelizing due to their sweet flavor, you can also use red onions or even white onions. Each will bring a slightly different taste to the dish. - What if I don’t have white wine or don’t want to use alcohol?
No problem! You can substitute the white wine with apple juice for a non-alcoholic option or even use chicken broth instead. The goal is to deglaze the pan and add some extra flavor. - Can I use a different cheese?
Yes, Gruyère and Swiss cheese are classic choices, but you can experiment with Comté, Emmental, or even a sharp white cheddar for a different twist. Make sure it is a cheese that melts easily. I would also suggest that you grate it yourself; it will melt more easily and contain fewer additives. Grating your own cheese usually means fresher and cheaper cheese as well. - How do I store leftovers?
Store any leftover chicken in an airtight container in the refrigerator. It should stay good for 3-4 days. You can reheat it in the oven or microwave until warmed through. - Can I make this recipe in a slow cooker?
While this recipe is designed for the stovetop and oven, you can adapt it for a slow cooker. Brown the chicken and onions first, then transfer everything to a slow cooker and cook on low for 4-6 hours. Note you won’t have the broiled effect on the cheese that we achieve by throwing the dish in the oven for a final crispy finale.
Onion Soup Variations
- Red Wine and Red Onions
For a deeper, richer flavor, try using red onions and deglaze with red wine instead of white. This will give the dish a beautiful color and a slightly different taste. - Herb Variations
Feel free to experiment with different herbs. Fresh rosemary, dried thyme, or a blend of Italian herbs can all add a unique twist to the dish. - Different Cuts
Chicken thighs could be great alternatives to chicken breasts, boneless or not. The cooking time may vary slightly, so adjust accordingly. - Different Sides
Serve your French Onion Soup Chicken with a variety of sides. Green beans, egg noodles, or even brown rice are great options that complement the flavors of the dish. - Cheese Options
While Swiss cheese and Gruyère are traditional, you can try other melty cheeses like mozzarella or even blue cheese for a stronger flavor.
