Why Make This Christmas Ham Egg Casserole Make Ahead Easy Feed A Crowd

This recipe is a game-changer for holiday hosting. First, it is the perfect way to use up leftover holiday ham, giving it a delicious second life. Second, the “make-ahead” nature means the bread has plenty of time to soak up the custard, resulting in a texture that is light and souffle-like rather than soggy. It feeds a large group with minimal effort, and because everything is contained in one baking dish, cleanup is a breeze. It is a crowd-pleaser that balances salty ham with sharp cheddar and fresh green onions, making it a hit for both kids and adults.

Ingredients

8 cups French bread or sourdough, cut into 1-inch cubes
2 cups cooked ham, diced
2 cups sharp cheddar cheese, shredded
1/2 cup green onions, sliced
10 large eggs
2 1/2 cups whole milk
1 teaspoon dry mustard
1/2 teaspoon onion powder
1/2 teaspoon salt
1/4 teaspoon black pepper
1/2 red bell pepper, finely diced (optional for color)

Directions

Step 1: Prepare the Baking Dish and Bread

Lightly grease a 9×13-inch baking dish with butter or non-stick cooking spray. Spread the cubed bread evenly across the bottom of the dish. Use a sturdy bread like French or Italian loaf to ensure the casserole holds its structure after soaking.

Step 2: Layer the Savory Ingredients

Scatter the diced ham and finely diced red bell pepper over the bread cubes. Sprinkle the shredded cheddar cheese and sliced green onions evenly over the top. Gently toss the ingredients with your hands or a spoon to ensure the ham and cheese are distributed throughout the bread layers.

Step 3: Whisk the Egg Custard

In a large mixing bowl, whisk together the eggs, whole milk, dry mustard, onion powder, salt, and black pepper. Whisk vigorously until the mixture is completely combined and the eggs are fully incorporated. The dry mustard is a secret ingredient that adds a subtle tang and enhances the cheese flavor.

Step 4: Soak and Refrigerate

Pour the egg mixture slowly and evenly over the bread and ham layers. Use a spatula to lightly press down on the bread cubes to make sure every piece is submerged or coated. Cover the dish tightly with plastic wrap or aluminum foil and refrigerate for at least 4 hours, or ideally, overnight.

Step 5: Bake to Perfection

Preheat your oven to 375°F (190°C). Remove the casserole from the refrigerator and let it sit at room temperature for about 20 minutes while the oven heats. Bake uncovered for 40 to 50 minutes, or until the center is set and the top is golden brown and slightly puffy. Let it rest for 10 minutes before slicing to allow the custard to firm up.

Expert Tips for Perfect Christmas Ham Egg Casserole Make Ahead Easy Feed A Crowd

For the best results, use “stale” bread. If your bread is fresh, toast the cubes in a low oven for 10 minutes to dry them out; this prevents the casserole from becoming mushy. Always shred your own cheese from a block if possible, as pre-shredded cheese is coated in potato starch and won’t melt as smoothly. If the top starts browning too quickly in the oven, loosely tent it with foil for the remaining bake time. Finally, don’t skip the resting period! Ten minutes of sitting ensures clean slices and a better texture.

Delicious Variations

Spice it Up: Add a can of chopped green chiles or a dash of hot sauce to the egg mixture for a southwestern flair.
Swiss and Mushroom: Swap the cheddar for Swiss cheese and add sautéed mushrooms instead of bell peppers.
Croissant Base: For a richer, more buttery experience, replace the French bread with torn-up croissants.
Veggie Packed: Stir in a handful of fresh baby spinach or steamed broccoli florets before adding the egg mixture.

Frequently Asked Questions

Can I bake this immediately without soaking overnight?

Yes, you can bake it right away, but the texture will be different. To ensure the bread absorbs enough liquid, let it sit for at least 30 minutes before putting it in the oven. The overnight soak is highly recommended for the best flavor and consistency.

How long will leftovers stay fresh?

Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. Reheat individual slices in the microwave or a toaster oven until warmed through.

Can I freeze this casserole?

You can freeze the baked casserole. Once cooled, wrap individual portions or the entire dish tightly in plastic wrap and foil. It will stay good for up to 2 months. Thaw in the refrigerator overnight before reheating.

What can I use instead of ham?

Cooked sausage crumbles or crispy bacon bits work beautifully in this recipe. For a vegetarian option, simply omit the meat and add more hearty vegetables like sautéed zucchini or sun-dried tomatoes.

Can I use low-fat milk?

You can use 2% milk, but avoid skim milk as it makes the custard too watery. For a truly decadent holiday version, you can even use half-and-half for part of the milk measurement.
