Gather these simple pantry and fridge staples to build the layers of creamy, cheesy, and crunchy goodness in your casserole:
Bringing all these ingredients together is simpler than it sounds. You’ll start by preheating the oven, then layer shredded chicken and ham with Swiss cheese before whisking up a creamy Dijon-spiked sauce. Once coated, the mixture goes into a greased casserole dish and gets topped with buttery breadcrumbs and cheese. A quick bake transforms it into a bubbly, golden masterpiece that’s ready to impress.
1. Preheat your oven to 350°F (175°C), ensuring it reaches the correct temperature before baking so your casserole cooks evenly.
2. In a large mixing bowl, combine the shredded chicken, diced ham, and half of the Swiss cheese, stirring until all pieces are well incorporated and distributed.
3. In another bowl, whisk together the milk, cream of chicken soup, Dijon mustard, garlic powder, onion powder, black pepper, paprika, and salt until smooth and lump-free.
4. Pour the soup mixture over the chicken and ham blend, then gently stir until every bit of protein is coated in the creamy sauce.
5. Transfer the coated mixture into a greased 9x13 inch casserole dish, spreading it out evenly for uniform baking.
6. In a separate bowl, combine the remaining Swiss cheese with the breadcrumbs, then drizzle in the melted butter and toss until the crumbs are evenly coated.
7. Sprinkle the breadcrumb and cheese mixture over the top of the casserole, pressing lightly so it adheres.
8. Bake for 30–35 minutes, or until the topping is golden brown and bubbly around the edges.
9. Once finished, remove from the oven and let the casserole rest for 5 minutes; this helps it set and makes serving easier.
10. Garnish with fresh chopped parsley before serving to add a pop of color and freshness.

Here are some quick answers to common questions about this cozy bake:
A: Prep time is about 15 minutes, which includes shredding the chicken, dicing the ham, and mixing ingredients. Bake time is 30–35 minutes at 350°F (175°C), plus a 5-minute resting period before serving, for a total of approximately 50–55 minutes from start to finish.
A: Yes, leftover cooked chicken or turkey works perfectly. Just shred or dice your meat to about the same size as shredded rotisserie chicken and proceed with the recipe. Ensure the meat is fully cooked and drained of excess moisture to avoid a watery casserole.
A: You can swap Swiss cheese for provolone, cheddar, or Gruyère. Choose a cheese that melts well and complements the flavors. If using a sharper cheese like cheddar, consider reducing the Dijon mustard slightly to maintain balance.
A: Lightly steam or sauté vegetables such as broccoli florets, chopped spinach, or peas until just tender. Drain any excess liquid and pat them dry before folding them into the chicken and ham mixture. This prevents added moisture from making the casserole runny.
A: Absolutely. Assemble the casserole through step 7, then cover and refrigerate for up to 24 hours. When ready to bake, remove the cover, pop it into a preheated 350°F oven, and bake for the full 30–35 minutes or until the topping is golden and bubbly.
A: Store leftover casserole in an airtight container in the refrigerator for up to three days. To reheat, bake individual portions in a 350°F oven for 15–20 minutes or microwave on medium power until heated through. You can refresh the topping by adding a few extra breadcrumbs and a dot of butter before reheating.
A: Replace the regular panko breadcrumbs with gluten-free breadcrumbs or crushed gluten-free crackers. Double-check that your cream of chicken soup and mustard are certified gluten-free. The rest of the ingredients are naturally free of gluten.
