Cheesy Ham & Spinach Casserole Recipe

Assembling the Casserole

Lightly grease a 9‑inch square baking dish. Spread the chopped spinach evenly across the bottom, then scatter the diced ham over the greens. Pour the cheese custard over the ham and spinach, using a spatula to ensure an even coating. The custard will soak into the spinach, creating a moist interior while the ham stays tender.

Adding the Crunchy Topping & Baking

1. Prepare the topping. In a small bowl, mix ½ cup panko breadcrumbs with 1 tablespoon melted butter until the crumbs are lightly coated. This will toast to a golden, buttery crust during baking.
2. Apply and bake. Sprinkle the breadcrumb mixture evenly over the casserole. Place the dish in the preheated oven and bake for 25–30 minutes, or until the top is golden brown and the custard is set (a knife inserted should come out clean). The visual cue of bubbling edges signals perfect doneness.
3. Rest before serving. Remove the casserole from the oven and let it rest for 5–7 minutes. Resting allows the custard to firm up, making slicing clean and preserving the creamy interior.
