Casserole Preparation

Preparing the Ham and Egg Casserole is a straightforward process that rewards you with a deliciously warm and satisfying dish. Follow these steps to ensure a perfectly baked result.

Mixing the Ingredients

Begin by preheating your oven to 350°F (175°C). Lightly grease an 8-inch square baking dish with nonstick cooking spray or a thin layer of butter.

In a large mixing bowl, crack the eggs (or your chosen egg combination) and whisk together with the milk and seasoned salt until smooth and fully combined. This step is crucial for creating a light and fluffy egg texture in the finished dish.

Once the eggs are well beaten, stir in the diced ham, grated cheddar cheese, and finely diced sweet onion. Mix gently to ensure all ingredients are evenly distributed throughout the egg mixture.

Assembling and Baking the Casserole

Pour the egg mixture into the prepared baking dish, using a spatula to evenly spread the ingredients if needed. Gently tap the dish on the counter to remove any air bubbles and settle the ingredients.

Place the dish in the preheated oven and bake for 40 to 45 minutes, or until the eggs are set and the top is lightly golden. To test for doneness, insert a knife into the center of the casserole—it should come out clean when ready.

Once baked, remove the casserole from the oven and let it cool for a few minutes. This helps the casserole set further and makes it easier to slice.

Serving and Presentation

A beautifully baked Ham and Egg Casserole is not only delicious but also makes a charming addition to any breakfast or brunch table. Here’s how to serve and elevate its presentation.

Portioning and Garnishing

Once the casserole has rested slightly after baking, use a sharp knife to cut it into even squares. A flexible spatula works best to lift the pieces cleanly from the dish.

For an added touch of freshness and visual appeal, garnish each serving with a sprinkle of chopped fresh chives or parsley. These herbs not only enhance the color contrast but also add a subtle burst of flavor that complements the richness of the eggs and ham.

Serving Suggestions

This casserole shines on its own, but pairing it with a few complementary items can round out the meal:

Fresh fruit or fruit salad for a refreshing contrast
Buttered toast, croissants, or English muffins for extra crunch and balance
A dollop of sour cream or hot sauce for those who enjoy a little extra zing

Whether you’re serving it straight from the baking dish or plating it individually, this casserole offers both rustic charm and comforting flavor with every bite.

Storage Instructions

Whether you’re preparing this casserole ahead of time or saving leftovers for later, proper storage ensures that every bite stays fresh and delicious.

How to Store Leftover Casserole

Allow the casserole to cool to room temperature before storing. Then, cover the baking dish tightly with foil or transfer individual portions to an airtight container. Refrigerate for up to 3 to 4 days.

To reheat, place a portion on a microwave-safe plate and warm in the microwave for 1–2 minutes, or reheat the entire dish in a 325°F oven until heated through (about 15–20 minutes).

Freezing for Later

Want to prepare your casserole in advance? This dish freezes beautifully. After baking and cooling completely, wrap the entire casserole (or individual slices) tightly in plastic wrap and a layer of foil. Store in the freezer for up to 2 months.

To enjoy later, thaw overnight in the refrigerator, then reheat in the oven at 325°F until warm. This makes it a perfect make-ahead option for busy mornings or holiday brunches.
