Step-by-Step Instructions for Chicken Cordon Bleu Casserole
Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This will ensure your casserole cooks evenly.
Layer the Chicken and Ham
In a 9 x 13-inch baking dish, spread the shredded cooked chicken evenly across the bottom. Next, layer the bite-sized pieces of ham over the chicken, ensuring even distribution.
Prepare the Sauce
In a large mixing bowl, combine the melted butter, cream cheese, mustard, wine, lemon juice, and salt. Use an electric mixer to blend the ingredients until a thick, smooth sauce forms.
Assemble the Casserole
Pour the prepared sauce evenly over the chicken and ham layers. Use a spatula to spread it out if necessary, ensuring the entire surface is covered.
Add the Cheese
Lay the slices of Swiss cheese over the sauce, covering the entire dish. This will create a rich, gooey topping as the casserole bakes.
Bake
Place the casserole in the preheated oven and bake for 30-40 minutes, or until the dish is hot and bubbling.
Broil for a Golden Finish
For a golden, bubbly cheese topping, switch your oven to broil for the last 2 minutes of baking. Keep a close eye on it to prevent burning.
Storage and Serving
Let the casserole cool for a few minutes before serving. It pairs well with a fresh salad, roasted vegetables, or a side of rice. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through.
Tips for Success
- Use Fresh Ingredients: Freshly cooked chicken and high-quality ham will enhance the flavor of the dish.
- Don’t Skip the Broil: Broiling at the end gives the cheese a deliciously crispy texture.
Variations
- Add Vegetables: Incorporate steamed broccoli or spinach for added nutrition.
- Spicy Kick: Add a pinch of red pepper flakes or a dash of hot sauce to the sauce mixture.
- Different Cheeses: Substitute Swiss cheese with Gruyère or mozzarella for a different flavor profile.
