This French Onion Chicken bake has quickly earned its spot at the top of our family’s favorite dinner list! I honestly can’t say enough good things about it.

How about we start with the obvious? It’s so EASY because I’ve prepared the baked chicken breasts using my hands-off dump-and-bake method.

How to Make French Onion Chicken:

We’re basically making French Onion Chicken Soup in casserole form. This dish has all of the flavors that you crave, with none of the work!

First, you’ll spread 2 large sweet, sliced onions in the bottom of a baking dish. Top the onions with raw chicken breasts, season with a bit of salt and pepper, and then tuck a few sprigs of fresh herbs among the meat.

Next, whisk together the sauce. This is GOLD.

It includes all of the familiar French Onion soup ingredients for a rich and savory broth.

Pour the sauce over your chicken and onions and then pop it in the oven!

As the chicken bakes and browns on top, the onions cook down and continue to add sweet flavor to the meat and the sauce.

The French Onion Chicken Casserole is the perfect combination of sweet, savory, and fresh ingredients!

Even if your kids don’t like onions, I promise: they will LOVE this meal (just leave the onions on the side and serve the plain diced chicken to your finicky eaters).

What to serve with French Onion Chicken:

It wouldn’t be French Onion Chicken without a slice or two of thick, cheesy, toasted bread. Don’t forget this vital finishing touch! The bread also makes a perfect dipping tool to soak up any extra broth that you might have lingering on your plate.

If you’d like to add some more vegetables to the meal, try serving your French Onion Chicken with:

Fried Cabbage with Apples and Onion
Slow Cooker Southern Green Beans
10-Minute Creamy Cucumber Salad
Garlic Roasted Broccoli
A simple green salad with Italian Balsamic Vinaigrette

COOK’S TIPS AND RECIPE VARIATIONS:

Other readers have substituted chicken thighs for the chicken breasts with great results!
Don’t skip the fresh herbs — they add so much great flavor to the dish!
I buy frozen Texas Cheese Toast as the easy bread addition to this French Onion Chicken; however, you can also substitute with any similar crusty bread that you enjoy. Make your own cheesy garlic bread at home with a loaf of French baguette, if you prefer.

Ingredients

2 large sweet onions very thinly sliced
4 boneless, skinless chicken breasts (about 2 ½ – 3 lbs. total)
2 sprigs fresh thyme
1 sprig fresh rosemary
½ cup beef broth
¼ cup olive oil
¼ cup Dijon mustard
2 tablespoons honey
1 tablespoon sherry or brandy
1 tablespoon Worcestershire sauce
2 tablespoons dry onion soup mix from a 1 ounce packet
¼ salt
For serving: frozen Texas Cheese Toast cooked according to package instructions (or other homemade cheese toast)

Instructions

Preheat oven to 350 degrees F. Spray a large, shallow baking dish with cooking spray.
Place sliced onion in the bottom of the prepared dish.
Season chicken with salt and pepper to taste and place on top of the onion. Add fresh herbs to the dish.
In a large bowl or measuring cup, whisk together beef broth, olive oil, Dijon mustard, honey, sherry, Worcestershire sauce, dry soup mix, and salt until completely combined.
Pour sauce over chicken.
Bake, uncovered, for about 45-55 minutes (or until chicken is cooked through and reaches an internal temperature of 165 degrees F). The cooking time will vary depending on the size and thickness of your chicken. Baste with pan sauce and garnish with additional fresh herbs, just before serving.
Serve with cheese toast.
