Why This Recipe is Awesome

This casserole is basically the culinary version of a mic drop. It tastes fancy enough to impress but is stupidly easy to assemble. You do minimal prep, and the oven does the heavy lifting. It is cheesy, a little tangy, and that crunchy panko top? Chef kiss.

It also plays well with leftovers. Got roasted chicken from last night? Use it. Bought ham on a whim? Perfect. This recipe is idiot proof and forgiving. If you mess up the sauce a tad, the cheese and ham will hide your sins. IMO this is the kind of dish that makes you look like you belong in a kitchen without requiring a cape.

Ingredients You’ll Need

5 cups shredded chicken. Yes, use rotisserie and call it a life hack.
9 ounces sliced deli-style black forest ham, cut into strips about 9 slices. Fancy tasting, zero effort.
8 ounces sliced Swiss cheese about 12 thin slices. Use what melts well.
6 Tablespoons unsalted butter. For the sauce. Trust it.
1 Tablespoon Dijon mustard. Don’t skip the Dijon. It gives personality.
1 Tablespoon freshly squeezed lemon juice optional, but it wakes things up.
1 teaspoon garlic powder. Easy flavor points.
½ teaspoon salt. Adjust to taste.
¼ teaspoon nutmeg optional, adds warmth if you are feeling bougie.
¼ teaspoon cayenne pepper optional, for a tiny kick.
6 Tablespoons all-purpose flour. For the roux, the unsung hero.
3 cups whole milk. Full fat makes a silkier sauce.
1 ½ cups Panko breadcrumbs. Crunch is mandatory.
4 Tablespoons unsalted butter softened to room temperature. For that golden topping.
Chopped parsley optional, for a sprinkle of color and vibes.

Step-by-Step Instructions

Preheat the oven to 350°F and spray a 9×13-inch casserole dish with nonstick cooking spray. Get that oven doing its thing while you assemble.
Evenly spread 5 cups shredded chicken into the baking dish. Make a nice, level bed for the rest.
Evenly layer 9 ounces sliced deli-style black forest ham, cut into strips over the chicken. Distribute the ham so every bite gets some.
Place 8 ounces sliced Swiss cheese evenly over the ham, overlapping the cheese slices to fit into the casserole dish. No gaps allowed.
Melt 6 Tablespoons unsalted butter in a saucepan over medium heat. Whisk in 1 Tablespoon Dijon mustard, 1 Tablespoon freshly squeezed lemon juice if using, 1 teaspoon garlic powder, 1/2 teaspoon salt, 1/4 teaspoon nutmeg if using, and 1/4 teaspoon cayenne pepper if using. Stir until the mixture smells like victory.
Sprinkle in 6 Tablespoons all-purpose flour and continue whisking over medium heat until it forms a paste. This is your roux. Don’t walk away.
Slowly add 3 cups whole milk a quarter of a cup at a time whisking after each addition until the mixture is smooth before adding the next bit of milk. Patience yields no lumps.
Once all the milk has been added allow it to simmer for 4 minutes or until the sauce has thickened whisking occasionally. The sauce should coat the back of a spoon.
Pour the sauce over the cheese layer and spread it evenly around as best as possible making sure to get in all the corners. Cover every cheesy inch.
Combine the 1 ½ cups Panko breadcrumbs and 4 Tablespoons unsalted butter softened to room temperature in a small bowl and spread this mixture evenly over the casserole dish as your final layer. Press lightly so it clings.
Bake in the oven uncovered for 30-40 minutes or until the sauce is bubbling and the Panko topping is golden brown. The kitchen will smell glorious.
Remove the casserole dish from the oven and let it sit for 5 minutes to allow the sauce to set. Sprinkle with chopped parsley optional and serve. Enjoy!

Common Mistakes to Avoid

Thinking you do not need to preheat the oven rookie mistake. The casserole cooks more evenly if the oven is ready.
Pouring milk all at once and expecting no lumps be patient when adding the milk. Whisk, then add more.
Skipping the mustard thinking it is optional but actually not. Dijon gives depth and prevents the sauce from being flat.
Using cold butter in the panko topping and wondering why it did not crisp properly. Soften the butter first.
Letting the casserole rest for zero seconds because patience matters. The sauce firms up and slices better after a quick rest.

Alternatives & Substitutions

No Swiss cheese? Use Gruyere or even a good melting cheddar. I like Gruyere for its nutty vibe.
No black forest ham? Try smoked turkey or thinly sliced cooked bacon for a smoky swap. My taste buds approve.
Want lighter milk? Go for 2 percent or a combination of milk and half and half if you want richer sauce with less milk.
Gluten free? Use a 1 to 1 gluten free flour for the roux and gluten free panko for the topping. It works surprisingly well.
No panko? Use crushed crackers or regular breadcrumbs but expect slightly less crunch. Still tasty though.

Also, if you like quick bakes with a similar no-fuss vibe try this four ingredient ranch chicken bake for another weeknight hero. Seriously quick and low drama.

FAQ (Frequently Asked Questions)

Q. Can I use margarine instead of butter?
A. Well technically yes but why hurt your soul like that? Butter gives flavor and browning. Margarine works in a pinch but the topping and sauce will not sing as nicely.

Q. Can I assemble this ahead of time and bake later?
A. Absolutely. Assemble and keep covered in the fridge for up to 24 hours. Add a few extra minutes to the bake time if it goes in cold from the fridge.

Q. Will this freeze well?
A. Yes. Freeze it before baking in an airtight container for up to 3 months. Thaw overnight in the fridge then bake as directed, adding a bit more time if it is still chilly in the center.

Q. Can I make this spicier without messing it up?
A. For sure. Add a dash more cayenne or a spoonful of grainy mustard. A few sliced jalapenos on top before baking also works if you like heat.

Q. Do I have to use panko for the topping?
A. No but panko gives that irresistible crunch. Regular breadcrumbs or crushed crackers work fine but will be denser. Panko = golden airy crunch every time.

Q. How do I get the sauce super smooth?
A. Whisk constantly while adding milk slowly. If you do get tiny lumps, strain the sauce through a fine mesh before pouring it over the casserole.

Q. What should I serve it with?
A. A crisp green salad, some roasted veggies, or buttered noodles. Honestly this casserole can stand alone like the star it is.
