The kids want chicken nuggets again. You want something that feels like a real dinner.

This cordon bleu chicken nugget casserole recipe is the answer. Crispy nuggets and melted provolone sit on top of diced ham, broccoli, and a creamy Swiss-Dijon sauce. Hands-on time is about 15 minutes. Picky eaters see a food they already trust. You get chicken cordon bleu flavor in one pan, with no pounding, rolling, or breading. It is kid friendly comfort food made for a busy weeknight dinner.

This recipe started with the Chicken Cordon Bleu Casserole from Joy Filled Eats. I swapped the shredded chicken for nuggets, lightened up the sauce, and added broccoli.

Ingredients for Cordon Bleu Chicken Nugget Casserole

This recipe makes one 9×13 casserole, or about 6 to 8 servings.

For the base

• 6 to 8 ounces uncured diced ham
• 3 cups small raw broccoli florets

For the lighter Swiss-Dijon sauce

• 4 tablespoons butter, melted
• 3 ounces light cream cheese, softened to room temperature
• 4 Laughing Cow Creamy Swiss wedges
• 1 tablespoon Dijon mustard
• 2 tablespoons lemon juice
• Salt and pepper, to taste
• 1 to 2 tablespoons 2% milk, only if the sauce needs thinning

For the topping

• 1 bag (24 oz to 2 lb) frozen chicken nuggets (I used Perdue high protein)
• 6 slices deli provolone cheese

How to Make Cordon Bleu Chicken Nugget Casserole

1. Crisp the nuggets. Bake the chicken nuggets from frozen according to package instructions, or make air fryer chicken nuggets to keep the oven free. Go to the long end of the time so they are extra crisp. Let them cool for a few minutes, then chop them into bite-size pieces.
2. Mix the sauce. In a large bowl, combine the melted butter, cream cheese, and Laughing Cow wedges and mix until smooth. Mix in the Dijon and lemon juice, then season with pepper. The sauce should be thick and spreadable. Add milk a tablespoon at a time only if it is too stiff to spread.
3. Build the base. Preheat the oven to 350 F and spray a 9 x 13 inch baking dish with cooking spray. Scatter the diced ham and raw broccoli across the bottom, then spread the sauce over the top and stir it all together.
4. Cover and bake. Cover the casserole dish with foil and bake for 15 to 20 minutes, until the broccoli starts to soften.
5. Add the nuggets. Take off the foil. Put the crispy chicken nuggets on top of the hot base in a single layer.
6. Top it off. Lay the provolone slices over the nuggets, overlapping them slightly.
7. Bake. Bake uncovered for about 10 minutes, until the cheese is melted and the sauce bubbles at the edges.
8. Broil. Broil for 1 to 2 minutes, until the cheese on top is golden brown. Watch it closely, because thin slices burn fast.
9. Rest. Let it rest for 5 minutes before serving so the sauce thickens.

Tips and Tricks for the Best Nugget Casserole

Crisping the nuggets first is the most important step. The air fryer does the best job if you have one.

Cut the broccoli small. Bite-size florets cook through in the covered bake. Big ones stay crunchy in the middle.

Keep the sauce thick. A thin sauce creeps up into the nuggets and softens the breading. The broccoli releases a little water as it bakes, so the sauce loosens on its own.

Foil goes on the base only. Covering the ham, broccoli, and sauce steams the broccoli. Take the foil off before the nuggets go on so they stay crisp.

Go easy on the salt and pepper. Taste the sauce first, since the ham, nuggets, and cheese bring plenty of salt.

Stay by the oven for the broil. Provolone goes from golden to burnt in under a minute.

Variations and Substitutions

Use this chart to adjust the recipe based on what you have on hand or what your family likes.

Swap This	For This
High protein nuggets	Homemade chicken nuggets, breaded chicken tenders, popcorn chicken, or gluten free nuggets
Diced ham	Chopped deli ham, leftover holiday ham, or cooked crumbled bacon
Raw broccoli	Thawed frozen broccoli squeezed dry, cauliflower florets, or 2 cups green beans
Laughing Cow wedges	2 ounces extra cream cheese plus a handful of shredded Swiss
Light cream cheese	Regular cream cheese or plain Greek yogurt
Provolone slices	Swiss, Havarti, or 1 cup shredded mozzarella cheese
Dijon mustard	Honey mustard for a sweeter, more kid-friendly sauce
2% milk	Chicken broth or any milk you have

For a crunchier top, sprinkle panko tossed with a little melted butter over the provolone before the final bake.

Chicken parmesan twist: Turn this into a chicken parmesan casserole. Skip the ham and Swiss sauce and start with one 24 oz jar of marinara sauce over pasta, with some ricotta. Put the chicken nuggets on top, then add 2 cups shredded mozzarella cheese and 1/2 cup grated parmesan cheese. Finish with Italian seasoning and fresh basil. This chicken nugget parmesan tastes like chicken parm with almost no work.

Classic creamy version: For a simpler chicken casserole, swap the Swiss-Dijon sauce for a can of cream of chicken soup mixed with 1/2 cup milk, and use 1 cup shredded cheese on top.

How to Store and Reheat Leftovers

Refrigerator: Cool the casserole within 2 hours of baking. Store it in an airtight container for up to 3 days.

Freezer: Freeze individual portions in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating. The sauce may look a little separated after thawing. A quick stir brings it back.

Oven reheating: Bake at 350°F for 15 to 20 minutes, until the center reaches 165°F. This method brings back the most crunch.

Air fryer reheating: Heat single portions at 350°F for 5 to 7 minutes in an oven-safe dish. It is the fastest way to re-crisp the nuggets.

Microwave reheating: Use this when speed matters most. The sauce warms well, though the nuggets will soften.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes. Assemble the ham, broccoli, and sauce base up to 24 hours ahead and refrigerate it covered. Crisp the nuggets and add them with the provolone right before the final bake. Add 5 to 10 minutes to the covered bake time since the base starts cold.

Do I need to thaw the chicken nuggets first?

No. Cook the nuggets straight from frozen. Thawed nuggets turn soft and soggy on top of the sauce.

Do I need to cook the broccoli first?

No. Small raw florets steam under the foil during the covered bake. If you like very soft broccoli, steam it for 2 to 3 minutes first and pat it dry.

Can I use regular Swiss cheese instead of Laughing Cow?

Yes. Use 6 ounces of cream cheese in the sauce and lay Swiss slices on top in place of the provolone. The casserole will be richer and closer to a classic cordon bleu.

How do I keep the nuggets from getting soggy?

Crisp them first, keep the sauce thick, and bake them uncovered. Serve the casserole soon after resting for the crispiest results.

Can I use homemade chicken nuggets or chicken tenders?

Yes. Homemade chicken nuggets, breaded chicken tenders, or leftover baked chicken all work. Make sure they are fully cooked and crisp before they go on top.

Can I make this casserole gluten free?

Yes. Use gluten free chicken nuggets and check the labels on the ham, cheeses, and mustard.

Can I make this in a slow cooker?

I would not. Slow cooker chicken casseroles trap steam, so the breading on the nuggets turns soft. The oven keeps them crisp.
