Step-by-Step Instructions for Making Savory French Onion Chicken Bake
Follow this step-by-step process, and you’ll be serving a restaurant-worthy dish in your own kitchen. Each step is important, so don’t rush. Trust the process.
Step 1 – Preparing the Chicken
First things first, slice each chicken breast into 2 to 3 thinner pieces. Place them between two sheets of plastic wrap and gently pound them to about ¼-inch thickness. This ensures even cooking and allows the chicken to soak in all that flavor. Once pounded, pat each piece dry with a paper towel. Season both sides generously with salt, pepper, garlic powder, and Italian seasoning. In a shallow bowl, mix together the all-purpose flour and shredded Parmesan. Dredge each piece of chicken in the mixture, coating it thoroughly. Heat olive oil and butter in a large skillet over medium-high heat. Sear the chicken on both sides until golden brown, about 3 minutes per side. You’re not cooking it all the way through—just giving it that beautiful crust. Once done, set the chicken aside and tent it with foil.
Step 2 – Caramelizing the Onions
Don’t clean the skillet—you’ll want all those brown bits left behind. Melt butter with a bit of olive oil over medium heat, then add the sliced onions. Stir to coat them, and cook for about 5 minutes until they begin to soften. Add the soy sauce, rosemary, thyme, and sage. Cover the skillet and lower the heat. Let the onions cook low and slow for about 30 minutes, stirring occasionally. This slow caramelization is what brings out their deep, sweet-savory flavor. Uncover and cook another 10 minutes over medium heat until they are golden brown and jammy.

Step 3 – Making the Savory Onion Sauce
Once your onions are beautifully caramelized, stir in the minced garlic and cook for about a minute. Sprinkle in the flour and stir for another 1–2 minutes to cook off the raw taste. Slowly pour in the beef broth and chicken broth while stirring constantly. Add in the bouillon cube and bring the sauce to a gentle boil. Let it simmer for about 3 to 5 minutes until thickened. Remove from heat. This sauce will be your flavor-packed base.
Step 4 – Assemble and Bake
Preheat your oven to 475°F. If you’re using an oven-safe skillet, great. If not, transfer the sauce and onions to a baking dish. Nestle the chicken pieces back into the sauce and generously sprinkle with shredded cheese. Bake for 15 to 20 minutes or until the cheese is bubbly and lightly browned. Garnish with fresh thyme if desired, and serve warm.
