Instructions:
- Preheat the oven to 375°F (190°C) and lightly grease a 9×13 baking dish.
- Spread the cooked chicken evenly in the dish, then layer the diced ham over the top.
- In a bowl, combine the cream of chicken soup, milk, sour cream, Dijon mustard, garlic powder, and onion powder. Mix until smooth. Pour this mixture evenly over the chicken and ham.
- Sprinkle the shredded Swiss cheese across the top.
- In a separate bowl, mix the crushed Ritz crackers with melted butter. Sprinkle the buttery crumbs over the casserole.
- Bake for 25 to 30 minutes, or until the casserole is hot and bubbly with a golden, crisp topping.
- Garnish with chopped chives and serve warm.
Variations
- Use smoked ham for a deeper, more robust flavor.
- Swap Swiss for Gruyère or provolone for a different cheesy profile.
- Add steamed broccoli or spinach for a vegetable boost.
- Replace Ritz crackers with panko for an extra-crunchy topping.
- Add a pinch of paprika to the topping for warmth and color.
Tips
- Ensure the cracker topping is evenly coated in butter so it browns perfectly.
- Cut the ham and chicken into uniform pieces for consistent bites.
- Let the casserole sit for 5 minutes before serving so the sauce thickens slightly.
- Pair with a crisp green salad or roasted vegetables to balance the richness.
- Leftovers reheat wonderfully—cover with foil and warm in the oven to keep the topping crisp.
