Start by slicing each chicken breast horizontally into thinner cutlets. Pat them dry with a paper towel. Season both sides generously with salt, pepper, and a light sprinkle of paprika. This helps create flavor and color when seared.
Heat a bit of oil in your frying pan over medium heat. Add the chicken pieces and sear them for about 3–4 minutes per side, just until golden. Don’t fully cook them yet — they’ll finish baking in the oven. Transfer the browned chicken to your baking dish.
In a mixing bowl, whisk together mayonnaise, honey, and mustard until creamy and smooth. This sauce doubles as both a marinade and topping, giving the dish its signature flavor.
Spread a spoonful of the honey-mustard sauce over each piece of chicken. Then layer sautéed mushrooms (if using), bacon slices, and cheese on top. Make sure every piece gets a generous amount — that’s what makes it irresistible.
Place the dish in a preheated 350°F (175°C) oven. Bake for 25–30 minutes or until the chicken is fully cooked and the cheese is melted and bubbly. Once baked, let it rest for a few minutes before serving.
