Let me tell you about my secret weapon for crazy weeknights – this easy chicken cordon bleu casserole! I discovered it during one of those evenings when my kids had soccer practice, the laundry was piling up, and I needed dinner on the table FAST. This recipe takes all the fancy flavors of traditional chicken cordon bleu – the tender chicken, smoky ham, and melty Swiss cheese – and turns them into a simple, dump-and-bake wonder. No fussing with rolling chicken breasts or worrying about them staying together. Just layer, pour, and bake while you tackle that mountain of laundry (or maybe just sit down for five blessed minutes). The best part? It tastes just as indulgent as the original with about a tenth of the work.

Why You’ll Love This Easy Chicken Cordon Bleu Casserole

- Kid-approved: Even my pickiest eater asks for seconds.
- Leftover gold: Tastes even better the next day (if there’s any left).
Trust me, once this hits your dinner rotation, you’ll wonder how you ever survived busy nights without it.
Ingredients for Easy Chicken Cordon Bleu Casserole
Here’s what you’ll need to make this lifesaver of a dinner – I promise it’s all simple stuff you probably have already:
- 2 cups cooked chicken, shredded (I always grab a rotisserie chicken – total time-saver!)
- 1 cup diced ham (the thicker the slices, the better the texture)
- 1 cup shredded Swiss cheese (buy the block and shred it yourself for extra creaminess)
- 1 cup shredded mozzarella (because more cheese is always better)
- 1/2 cup breadcrumbs (panko gives the best crunch)
- 1/4 cup melted butter (makes that topping irresistible)
- 1 can (10.5 oz) cream of chicken soup (the secret sauce!)
- 1/2 cup milk (whole milk makes it extra rich)
- 1 tsp Dijon mustard (just enough tang to cut through the richness)
- 1/2 tsp garlic powder + 1/2 tsp onion powder (my flavor-boosting duo)
- Salt and pepper to taste (don’t skip – it makes all the difference)
See? Nothing fancy – just good, comforting ingredients that come together like magic.
How to Make Easy Chicken Cordon Bleu Casserole
Okay friends, let’s get this show on the road! This casserole comes together so fast you’ll be checking the oven timer every five minutes just waiting to dig in. Here’s exactly how I make it – follow these steps and you’ll have a golden, bubbly masterpiece in no time.
Step 1: Prep the Sauce
First things first – that glorious sauce that makes everything come together! Grab your biggest mixing bowl (I use the same one my mom gave me when I went to college – sentimental kitchen items are the best). Dump in the cream of chicken soup, milk, Dijon mustard, garlic powder, onion powder, and a good pinch of salt and pepper. Whisk it all together until it’s completely smooth – no lumps allowed here! You’re looking for a consistency like thick pancake batter. This saucy mixture is going to seep through all those layers and make every bite moist and flavorful.
Step 2: Layer the Casserole
Now the fun part – building those delicious layers! Start with half your shredded chicken spread evenly across the bottom of your greased baking dish. Don’t be shy – really press it down so you get a solid foundation. Next comes half the diced ham (I like to sprinkle it rather than dump it so every bite gets some). Then comes the cheese – oh that glorious cheese! Use half the Swiss and half the mozzarella here. Now repeat the whole beautiful process: remaining chicken, remaining ham, and the rest of both cheeses. Pro tip: I always save a small handful of cheese to sprinkle on top right before baking for extra gooeyness.
Step 3: Add the Topping
Time for the crowning glory! In a small bowl, mix your breadcrumbs with that melted butter until every crumb is coated and happy. I use a fork to really work it in – you’ll know it’s ready when it looks like wet sand at the beach. Sprinkle this evenly over the entire casserole, covering every inch of cheesy goodness. Don’t press it down – you want those crumbs to stay light and crispy as they bake.
Step 4: Bake to Perfection
Into the oven it goes at 375°F (that’s 190°C for my metric friends). Set your timer for 25 minutes, but start peeking around 20 – oven temperatures can be sneaky! You’ll know it’s done when the edges are bubbling like crazy and that topping turns a beautiful golden brown. The smell will have your whole family gathered in the kitchen, plates in hand. Let it rest for about 5 minutes before serving – I know it’s hard to wait, but this lets everything set up so you get perfect slices instead of a cheesy landslide!
Tips for the Best Easy Chicken Cordon Bleu Casserole
After making this casserole more times than I can count (seriously – my family requests it weekly!), here are my hard-earned secrets:
- Rotisserie chicken is your friend – saves you at least 20 minutes of prep time!
- Watch the baking time – ovens vary, so pull it when the top is golden, not dark brown.
- Let it rest – those 5 minutes make all the difference for neat slices.
- Freshly shredded cheese – it melts so much better than pre-shredded.
- Double the recipe – because you’ll definitely want leftovers.
Follow these simple tricks, and you’ll have the most delicious, foolproof casserole every single time!
Variations for Your Easy Chicken Cordon Bleu Casserole
Oh, the possibilities! This recipe is like your favorite little black dress – endlessly adaptable. Here are my go-to twists when I’m feeling creative:
- Turkey instead of ham – perfect for using up holiday leftovers
- Gluten-free breadcrumbs – crushed pork rinds work shockingly well too!
- Add mushrooms – sauté them first for extra umami goodness
- Spice it up – a dash of cayenne or smoked paprika wakes up all the flavors
- Different cheeses – try Gruyère or fontina for a fancy twist
The best part? Every version tastes like you spent hours in the kitchen. Our little secret!
Serving Suggestions for Easy Chicken Cordon Bleu Casserole
This casserole shines all on its own, but here’s how I love to round out the meal:
- Crisp green beans – the fresh crunch balances the rich casserole perfectly
- Simple garden salad with a tangy vinaigrette to cut through the creaminess
- Garlic bread – because mopping up every last cheesy bite is mandatory
- Roasted baby potatoes when we’re extra hungry (which is always!)
Honestly? Sometimes we just eat it straight from the pan with forks – no judgment here!
Storing and Reheating Easy Chicken Cordon Bleu Casserole
Here’s the best part about this casserole – it keeps like a dream! Leftovers (if you’re lucky enough to have any) stay fresh in the fridge for 3-4 days. Just cover tightly with foil or transfer to an airtight container. For longer storage, freeze individual portions in freezer-safe containers for up to 1 month.
When reheating, I’ve found the microwave works fine in a pinch (cover with a damp paper towel to keep it moist), but for that just-baked taste, pop it in the oven at 350°F until heated through – about 15 minutes for fridge-cold portions, 30 if frozen. The cheese gets all melty again and that crispy topping comes back to life!
Nutritional Information
Now, I’m no nutritionist, but here’s the scoop on what you’re getting in each comforting serving of this easy chicken cordon bleu casserole. Keep in mind these numbers can change depending on the exact ingredients you use – like if you go heavy on the cheese (no judgment here!) or use low-sodium soup. Per serving (about 1/6th of the casserole), you’re looking at:
- 420 calories – totally worth every one!
- 35g protein – thanks to all that chicken and ham
- 22g fat (11g saturated) – hello, delicious cheese and butter
- 18g carbs – mostly from those crispy breadcrumbs
- 850mg sodium – you can reduce this with low-sodium ingredients
Remember, these are estimates – your mileage may vary based on brands and portion sizes. But honestly? When you’re digging into this cheesy, comforting dish after a long day, the numbers matter a whole lot less than how happy it makes your tastebuds!
FAQs About Easy Chicken Cordon Bleu Casserole
Can I use fresh chicken instead of cooked?
Absolutely! Just bake or sauté 2 chicken breasts (about 1 lb) until no longer pink, then shred. I sometimes do this on Sunday meal prep days – makes weeknight assembly even faster.
How long do leftovers last?
They’ll keep in the fridge for 3-4 days (though in my house, they never last that long!). The flavors actually get better as they meld. For longer storage, freeze portions up to 1 month.
Can I make this ahead?
You bet! Assemble everything except the breadcrumb topping, cover tightly, and refrigerate overnight. Add the topping right before baking – may need 5 extra minutes in the oven since it’s cold.
What if I don’t have Swiss cheese?
No sweat! Try provolone or Gruyère. Even mild cheddar works in a pinch. The key is using a good melting cheese that complements the ham. For a different flavor profile, consider trying a new cheese.
Is there a way to make it gluten-free?
Easy swap! Use gluten-free breadcrumbs or crushed pork rinds for the topping, and check that your cream of chicken soup is GF. Turns out just as delicious! For other dietary swaps, check out this guide.
