Step 1: Marinate the Chicken

Prepare the Marinade: In a medium bowl, combine 1 cup of honey mustard dressing with salt and pepper. This will not only flavor the chicken but also keep it moist during cooking.

Marinate the Chicken: Place the chicken breasts in a large resealable plastic bag or a shallow dish. Pour the honey mustard mixture over the chicken, making sure each piece is well-coated. Seal the bag or cover the dish and refrigerate for at least 1 hour, or up to overnight for maximum flavor.

Step 2: Preheat Your Oven and Prepare the Baking Dish

Preheat the Oven: Set your oven to 375°F (190°C) to make certain it's hot and ready for the chicken.

Prepare the Baking Dish: Lightly grease a large baking dish or a rimmed baking sheet with cooking spray or a drizzle of olive oil to prevent the chicken from sticking.

Step 3: Cook the Chicken

Sear the Chicken: In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Once the oil is shimmering, carefully add the marinated chicken breasts to the skillet. Sear the chicken for about 4-5 minutes on each side, or until golden brown. This step helps to lock in the juices and adds a delicious crust.

Transfer to Baking Dish: Once seared, transfer the chicken breasts to the prepared baking dish.

Step 4: Add Toppings

Cook the Mushrooms: In the same skillet, add the sliced mushrooms. Sauté them over medium heat for about 3-4 minutes, or until they are tender and slightly browned. This enhances their flavor and texture.

Layer the Ingredients: Evenly distribute the sautéed mushrooms over the chicken breasts. Then, sprinkle the chopped bacon evenly on top of the mushrooms. Finally, generously cover each chicken breast with shredded Monterey Jack cheese, making sure each piece is well-coated for that gooey, melty goodness.

Step 5: Bake the Chicken

Bake: Place the baking dish in the preheated oven and bake for approximately 20-25 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C). The cheese should be melted and bubbly, creating a delicious topping.

Step 6: Serve

Plate the Chicken: Once cooked, remove the baking dish from the oven. Let the chicken rest for a few minutes to allow the juices to redistribute.
