Ingredients

• 2 pieces boneless, skinless chicken breasts
• 2 tablespoons olive oil
• 2 tablespoons unsalted butter
• 1 medium yellow onion, diced
• 3 cloves garlic cloves, minced
• 3 tablespoons all-purpose flour
• 2 cups chicken broth
• 1 cup heavy cream
• 1 teaspoon dried thyme
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 0.5 cup shredded cheese (optional)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Heat a large skillet over medium-high heat and add 1 tablespoon of olive oil.

Step 3

Season the chicken breasts with salt and pepper on both sides. Sear the chicken in the skillet for 4-5 minutes on each side, until golden brown but not fully cooked through. Remove from the skillet and set aside.

Step 4

In the same skillet, lower the heat to medium and add the remaining olive oil and butter.

Step 5

Add the diced onion and sauté for 3-4 minutes until softened and translucent. Stir in the minced garlic and cook for an additional minute until fragrant.

Step 6

Sprinkle the flour over the onion and garlic mixture, stirring constantly for 1-2 minutes to cook out the raw flour taste.

Step 7

Gradually whisk in the chicken broth, ensuring there are no lumps, then stir in the heavy cream. Let the sauce simmer gently for 5-7 minutes until thickened.

Step 8

Stir in the dried thyme, salt, and black pepper. Taste the sauce and adjust seasoning as needed.

Step 9

Optional: Stir in shredded cheese for a creamier sauce.

Step 10

Cut the seared chicken into bite-sized pieces and add it to the casserole dish. Pour the prepared sauce over the top, ensuring the chicken is evenly coated.

Step 11

Cover the casserole dish with foil and bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through and the sauce is bubbling.

Step 12

Remove from the oven and let it rest for 5 minutes before serving or using as a base for additional casserole ingredients.
