Ingredients

To make a French Onion Chicken Bake, gather the following:

2 cups cooked chicken, shredded or diced (rotisserie chicken works great)
2 large onions, thinly sliced
2 tablespoons butter
1 teaspoon olive oil
2 cloves garlic, minced
1 teaspoon fresh thyme (or ½ teaspoon dried)
1 teaspoon salt
½ teaspoon black pepper
1 cup shredded Swiss cheese (or Gruyère for more authentic French flavor)
½ cup grated Parmesan cheese
4 large eggs
1 cup milk (whole milk for creaminess)
1 teaspoon Dijon mustard
1 teaspoon Worcestershire sauce (optional, for depth)
Fresh parsley, chopped, for garnish

Step-by-Step Method

Step 1: Preheat and Prepare

Start by preheating your oven to 375°F (190°C). Grease a 9×13-inch baking dish with a little butter or non-stick spray to prevent sticking.

Step 2: Caramelize the Onions

In a large skillet, heat butter and olive oil over medium heat.
Add the sliced onions and cook slowly, stirring occasionally for 15–20 minutes, until they are soft, sweet, and golden brown.
Add minced garlic, thyme, salt, and pepper in the last 2 minutes of cooking. Stir well and remove from heat.

Pro Tip: Slow-cooked onions are the secret to the rich French onion flavor. Resist the urge to rush this step!

Step 3: Layer the Chicken and Onions

Spread the shredded chicken evenly in the bottom of your prepared baking dish.
Layer the caramelized onions over the chicken. Make sure the onions cover the chicken completely for maximum flavor.
