Easy Overnight Ham and Cheese Casserole

1 package (10 ounces) frozen chopped spinach, thawed

4 eggs

2 cups whole milk

½ cup light mayonnaise

1 tablespoon Dijon mustard

½ teaspoon kosher salt

½ teaspoon ground black pepper

½ teaspoon onion powder

20-ounce ham steak, diced

3 cups shredded sharp cheddar cheese, divided

2 medium carrots, grated

2 medium turnips, grated

1 package (20 ounces) refrigerated shredded potatoes

Coat a 9-by-13-inch baking pan with cooking spray.

Place the spinach in a mesh strainer and squeeze out as much water as possible. Set aside.

In a large bowl, beat the eggs with the milk, mayonnaise, mustard, salt, pepper and onion powder until smooth. Stir in the squeezed spinach, ham, 2 cups of the cheese, the carrots, turnips and potatoes. Spoon the mixture into the prepared pan. Sprinkle the remaining 1 cup of cheese over the top of the casserole. At this point, the casserole can be covered and refrigerated for up to 1 day.

When ready to bake, heat the oven to 350 degrees. Bake 45-60 minutes, or until puffed and golden and a knife inserted at the center comes out clean. Serve warm.

Serves 12.
