Next, transfer the mixture into a greased 9×13 baking dish, spreading it evenly. In a small bowl, combine the breadcrumbs with melted butter and stir until the breadcrumbs are coated. This step is a game-changer; it creates that crunchy topping that contrasts beautifully with the creamy filling. Sprinkle the breadcrumb mixture over the casserole, ensuring to cover it evenly. Then, pop it into your preheated oven and bake for about 25-30 minutes, or until the casserole is bubbly and the top is golden brown. The kitchen will soon be filled with an inviting aroma—I can already taste it!
Once it’s baked, let the casserole cool for a few minutes before serving. This moment is crucial! Allowing it to sit helps to set the layers, making it easier to serve. When you dig in, you’ll love how the creamy chicken and ham, mingled with the crunchy topping, create a wonderful blend of textures and flavors that is pure comfort food.
Pro Tips for Best Results
I tested this casserole with both homemade and store-bought cream of chicken soup, and while both tasted great, I found that homemade has a richer flavor. If you have a bit of time, consider making your own! It’s surprisingly easy and adds that extra touch of love to the dish.
Another tip I’ve learned is to add a dash of garlic powder to the breadcrumb topping. It elevates the flavor without overpowering the main ingredients. Trust me; everyone will appreciate this little tweak as it adds an extra layer of deliciousness.
Lastly, don’t skip the resting time after baking! I like to let it rest for about 10 minutes before serving to ensure that the casserole holds together nicely when you slice into it. It’s the little things that make a big difference, and this is one of those moments.
Common Mistakes to Avoid
One common mistake I’ve made in the past is not using enough cheese. With a recipe focused on “Cordon Bleu,” cheese is truly a star ingredient. I now make sure to generously coat the top layer, which results in that beautiful melty texture that everyone craves.
Another thing to watch out for is overbaking. If you leave it in the oven too long, the casserole can become dry. Keep an eye on it and perhaps set a timer for 5 minutes less than the suggested baking time so you can check the consistency early.
Also, make sure your ingredients are at room temperature before mixing. I sometimes forget to pull the cream of chicken soup and sour cream out in advance, and it can make mixing a bit tricky. Warm ingredients simply blend together much more smoothly!
