1-First Step: Prepare the Chicken Begin by slicing each of the 2 large boneless, skinless chicken breasts into 2 to 3 thinner pieces. Place them between plastic wrap and pound to about ¼ inch thick for even cooking. Pat the chicken dry and season with salt, pepper, garlic powder, and Italian seasoning this helps the flavors of your French onion chicken really shine. Mix ½ cup flour with ¼ cup shredded Parmesan cheese, then dredge each piece in this mixture for a crispy coating. Heat 3 tablespoons olive oil and 1 tablespoon butter in a skillet over medium-high heat, then sear the chicken for about 3 minutes per side until it’s golden brown. If you’re adapting for dietary needs, like going gluten-free, swap the flour here accordingly. Set the chicken aside and cover with foil to keep it warm while you move on.

2-Second Step: Caramelize the Onions Slice the 3 yellow onions into ¼-inch slices to get that signature sweet base for your caramelized onion chicken. In the same skillet, melt 2 tablespoons unsalted butter and add 1 tablespoon olive oil over medium heat. Scrape up any browned bits from the chicken to add extra flavor. Toss in the sliced onions and cook for 5 minutes to soften them. Stir in 1 tablespoon low sodium soy sauce, 1 teaspoon dried rosemary, 1 teaspoon dried thyme, and ¼ teaspoon ground sage, then cover and cook on low heat for 30 minutes, stirring occasionally. For variations, you might add seasonal herbs if you prefer. Uncover, increase the heat to medium, and cook for another 10 minutes, stirring frequently, until the onions are caramelized and golden.

3-Third Step: Make the Sauce Once the onions are ready, add the 3 minced garlic cloves and ½ cup dry white wine to the skillet. Let it cook uncovered for about 10 minutes until the wine nearly reduces, building a rich base for your French onion chicken with melted cheese. Stir in 2 tablespoons flour to coat and cook for 1 to 2 minutes to remove any raw taste. Pour in 1 cup beef broth, 1 cup chicken broth, and 1 beef bouillon cube, then bring to a gentle boil over medium-high heat. Reduce for 3 to 5 minutes to thicken the sauce if you’d like it milder, skip the bouillon for dietary adjustments. This step is key for that authentic flavor in your easy French onion chicken recipe.

4-Fourth Step: Bake the Dish If your skillet isn’t oven-safe, transfer the mixture to an oven-safe dish. Return the seared chicken to the skillet or dish, then top with the 2 cups shredded mozzarella cheese. Bake at 475 degrees Fahrenheit for 15 to 20 minutes until the cheese is browned and bubbling keep an eye on it for the perfect melt. For variations, try different cheeses like Gruyere for a stronger taste. Once it’s out of the oven, garnish with fresh thyme and serve hot.
