What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without any complicated steps. Here’s what you’ll need:

• Cooked chicken breasts: Shredded or diced (rotisserie chicken works great for a time-saver).
• Sliced ham: Deli-style or leftover ham, diced into bite-sized pieces.
• Swiss cheese: Shredded or thinly sliced (Gruyère works beautifully too).
• Unsalted butter: For the base of the creamy sauce.
• All-purpose flour: Helps thicken the sauce to a luscious consistency.
• Milk: Whole milk is ideal for richness (but you can substitute with 2% or even almond milk).
• Cream cheese: Softened, for an extra creamy touch.
• Breadcrumbs: Panko or regular, for the crunchy topping.
• Olive oil: To mix with the breadcrumbs for a golden finish.
• Salt and pepper: To season the sauce perfectly.
• Optional: Dijon mustard (adds a tangy depth to the sauce).

Pro tip: If you’re in a pinch, pre-cooked grilled chicken strips or leftover holiday ham work wonders in this recipe. You can even swap in gluten-free breadcrumbs and flour to make it gluten-free!

Equipment Needed

• Casserole dish: A 9×13-inch dish is perfect for layering and baking this recipe.
• Medium saucepan: For whipping up that heavenly cheese sauce.
• Whisk: Essential for a smooth, lump-free sauce.
• Mixing bowls: For combining the topping and prepping ingredients.
• Knife and cutting board: To dice the chicken and ham.
• Measuring cups and spoons: For precise measurements.

If you don’t have a whisk, a fork can work in a pinch for the sauce. And as for casserole dishes, glass or ceramic both do the trick—just make sure it’s oven-safe!

Preparation Method

1. Preheat your oven: Set it to 350°F (175°C) and grease your casserole dish lightly with olive oil or butter.
2. Prepare the chicken and ham: Shred or dice the cooked chicken breasts and dice the ham into bite-sized pieces. Set aside.
3. Make the cheese sauce:
   1. In a medium saucepan, melt 2 tablespoons of butter over medium heat.
   2. Whisk in 2 tablespoons of flour and cook for 1-2 minutes to eliminate the raw flour taste.
   3. Gradually add 2 cups of milk, whisking constantly to avoid lumps. Cook until thickened, about 5 minutes.
   4. Stir in 4 ounces of cream cheese and 1 cup of shredded Swiss cheese until melted and smooth. Season with salt, pepper, and 1 teaspoon of Dijon mustard if desired.
4. Layer the casserole:
   1. Spread half of the shredded chicken in the casserole dish.
   2. Top with half of the diced ham and half of the cheese sauce.
   3. Repeat the layers with the remaining chicken, ham, and sauce.
5. Prepare the topping: In a small bowl, mix 1 cup of breadcrumbs with 1 tablespoon of olive oil. Sprinkle evenly over the casserole.
6. Bake: Place the casserole in the oven and bake for 25-30 minutes, or until the topping is golden and the sauce is bubbling.
7. Serve: Let the casserole cool for 5 minutes before serving to allow the layers to settle.

Tip: If your sauce looks too thick, just whisk in a splash of milk to loosen it up. And don’t skip the breadcrumb topping—it’s the perfect finishing touch!

Cooking Tips & Techniques

• Use rotisserie chicken: It’s a lifesaver when you’re short on time.
• Don’t skip the Dijon mustard: It adds a subtle tang that balances the richness of the sauce.
• Toast the breadcrumbs: For extra crunch, toast the breadcrumbs in a pan with olive oil before topping the casserole.
• Go easy on the salt: Ham and Swiss cheese are naturally salty, so taste the sauce before adding more salt.
• Let it rest: Allow the casserole to sit for a few minutes after baking—this helps the layers set and makes serving easier.

Variations & Adaptations

• Low-carb option: Skip the breadcrumbs and use crushed pork rinds for the topping.
• Vegetarian twist: Replace the chicken and ham with roasted vegetables like zucchini, mushrooms, and bell peppers.
• Gluten-free version: Use gluten-free flour and breadcrumbs to make this dish suitable for gluten-sensitive eaters.
• Seasonal swap: Add a layer of sautéed spinach or kale for a pop of green and extra nutrition.
• Personal variation: I’ve tried adding a sprinkle of nutmeg to the sauce—it’s subtle but elevates the flavor beautifully!

Serving & Storage Suggestions

This casserole is best served warm, right out of the oven. Pair it with a crisp green salad or steamed veggies for a balanced meal. A glass of white wine or sparkling water makes a great accompaniment!

For leftovers, store the casserole in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a 350°F (175°C) oven for 15-20 minutes or microwave individual portions for 1-2 minutes. You can also freeze it for up to 2 months—just thaw overnight in the fridge before reheating.

Pro tip: The flavors deepen as it sits, so it’s even better the next day!
