Creating a delicious Creamy Herb Chicken Bake is simple when you follow these clear steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).

2. Prepare Chicken: Season the chicken breasts with salt and pepper on both sides.

3. Sear Chicken: In a large oven-safe skillet, heat the olive oil over medium-high heat. Add the chicken breasts and sear for 4-5 minutes on each side until golden brown. Remove the chicken from the skillet and set aside.

4. Make the Sauce: In the same skillet, reduce the heat to medium. Add the heavy cream, chicken broth, Dijon mustard, garlic powder, onion powder, parsley, thyme, and rosemary. Stir well to combine and bring to a simmer.

5. Return Chicken: Place the seared chicken breasts back into the skillet, spooning some sauce over the top.

6. Add Cheese: Sprinkle the mozzarella and Parmesan cheese evenly over the chicken and sauce.

7. Bake: Transfer the skillet to the preheated oven. Bake for 25-30 minutes, or until the chicken is cooked through and the cheese is bubbly and golden.

8. Rest: Remove from the oven and let it rest for 5 minutes before serving.

By following these straightforward steps, you’ll have a creamy, herb-infused chicken dish that is sure to impress!
