2) Easy Chicken Cordon Bleu Casserole Recipe

Let me guess. It’s dinner time, you’re tired, and the fridge is looking like a game of leftovers meets mystery Tupperware. That’s exactly how this casserole came to life in my kitchen. I had a little leftover chicken, some ham from sandwiches, and a wild craving for something cheesy. Next thing I know, this easy chicken cordon bleu casserole was born and it hasn’t left our dinner rotation since.

Two things I love about this recipe. First, no breading or frying. Just layer, bake, and done. Second, it checks every box on a weeknight: fast, hearty, and everyone asks for seconds. I use shredded rotisserie chicken, which saves a ton of time. Add ham, Swiss, and a creamy sauce, and you’re basically a dinner genius.

What I like most is how the cracker topping bakes up crisp while the inside stays creamy. It hits the spot when you want comfort without spending all evening in the kitchen. And let’s be honest, dishes like this feel like a warm hug when the day has been a little too much.

3) Ingredients for Chicken Cordon Bleu Casserole

Shredded Chicken I go for rotisserie chicken because it’s quick and juicy. If you’ve got leftover baked or grilled chicken, that works too. Just shred it up and you’re good to go.

Diced Ham Look for something thick-cut and smoky. I usually dice up leftover ham from the weekend, but sandwich slices chopped up work fine too. Just keep the flavor bold.

Swiss Cheese Shredded Swiss melts into a gooey layer that brings everything together. If Swiss isn’t your thing, try mozzarella or even provolone, but Swiss gives it that cordon bleu character.

Cream of Chicken Soup This is where the sauce starts. You can use store-bought or homemade if you’re feeling ambitious. Either way, it brings that creamy, nostalgic base.

Sour Cream It balances out the saltiness and gives the casserole a nice tang. I sometimes swap in plain Greek yogurt when I want to feel slightly healthier.

Dijon Mustard Just a little goes a long way. It sharpens the flavor without overpowering anything. Don’t skip it—it adds that restaurant-style richness.

Garlic Powder and Pepper These boost the base flavor. You don’t need much, but you’ll notice if they’re missing.

Buttery Crackers Crushed Ritz crackers make the best topping. They turn golden and crisp, which adds texture and that “something extra” on top.

Melted Butter Toss this with the cracker crumbs before baking. Trust me, it’s the secret to that crave-worthy crunch.

Fresh Parsley This is totally optional, but I like to sprinkle some on top before serving. Makes it feel a little fresher and fancier than it really is.

4) How to Make Chicken Cordon Bleu Casserole

Step 1. Preheat the oven to 375°F and grease your favorite 9×13-inch baking dish. You want it ready to go when the mix is done.

Step 2. In a big bowl, stir together the soup, sour cream, Dijon mustard, garlic powder, and black pepper. It’ll look a little strange at first, but it smooths out quickly.

Step 3. Add your shredded chicken and chopped ham to the bowl. Fold them into the sauce gently but thoroughly, making sure everything’s coated evenly.

Step 4. Spread the creamy chicken and ham mixture into your prepared dish. Use a spatula to level it out—it doesn’t need to be perfect.

Step 5. Sprinkle the shredded Swiss cheese evenly across the top. Don’t be shy. This is your cheesy moment.

Step 6. In a small bowl, toss the crushed crackers with melted butter until every crumb is slick. Sprinkle this mix on top of the cheese layer.

Step 7. Pop the casserole in the oven for 25 minutes. You’ll know it’s ready when the top is golden and you can hear it bubbling underneath.

5) Tips for Making Chicken Cordon Bleu Casserole

Make sure your chicken is fully cooked before it goes into the mix. This casserole isn’t for cooking raw meat—it’s all about assembly and reheating.

For an extra kick, add a pinch of cayenne pepper to the sauce. I’ve done this when serving adults, and it adds a nice little heat without turning the dish spicy.

If you’re out of Swiss cheese, try mozzarella or Monterey Jack. Both melt beautifully and still let the flavors shine. I don’t recommend cheddar—it takes over the dish a bit too much.

Using Greek yogurt instead of sour cream? Go for the full-fat kind. It keeps the casserole creamy and doesn’t break in the oven.

Want to freeze it? Assemble everything except the cracker topping. Freeze the base, then thaw and add the cracker layer right before baking. Easy chicken casserole recipes freeze better this way.

6) Making Chicken Cordon Bleu Casserole Ahead of Time

One thing I’ve learned from busy weeknights is that make-ahead meals are lifesavers. This casserole fits the bill. You can prep it the night before and stash it in the fridge, covered with foil.

If you’re prepping in advance, hold off on the cracker topping. Add that right before you bake so it doesn’t get soggy. That crispy bite is worth the wait, trust me.

This also works great for bringing to someone else’s house. Just prep everything, cover it up, and bring it unbaked. Let them toss it in the oven when it’s time. Easy, thoughtful, and delicious.

7) Storing Leftover Chicken Cordon Bleu Casserole

Let the casserole cool before you transfer it to an airtight container. It keeps well in the fridge for up to four days and reheats nicely in the oven or microwave.

If you’re planning to reheat in the oven, cover the dish loosely with foil and bake at 350°F until warmed through. You can crisp up the top again by removing the foil for the last few minutes.

This recipe also makes a solid lunch. I portion it into glass containers and warm it up at work. Easy chicken casserole recipes like this one are a lifesaver when the week gets hectic.
