Overnight Ham and Egg Breakfast Casserole is a delicious make-ahead recipe that features ham, sharp cheddar cheese, a rich egg custard, and cubed bread.
Whenever I have leftover ham from Instant Pot Ham or Oven Baked ham, I set aside cubed ham to make this ham and egg casserole. It is especially delicious when made with Cranberry Walnut Bread or Cinnamon Raisin bread, giving this casserole sweet notes that pair perfectly with the savory ham.
There is something about sweet and savory combinations at breakfast.
And when you can combine sweet and savory into one dish, as this Ham and Egg Casserole does, you can guarentee it satisfies.
From the sweet and savory ham, sharp cheddar, sweet cinnamon raisin bread and a rich egg base this breakfast casserole delivers on flavor.
And because this recipe is designed to be prepared in advance, an overnight ham and egg casserole, it is absolutely PERFECT for entertaining. Prep the night before, and your only job will be to brew the coffee while your casserole bakes.
Notes on Key Ingredients
- Bread: Cranberry Walnut Bread or Cinnamon Raisin Bread is my choice for this ham and egg casserole as it lends a subtle sweetness to the dish. However, you can use whole wheat bread, french bread, brioche bread, or even gluten-free bread.
- Ham: Use leftover diced ham or cube up a large piece of ham steak. If you don't have ham, diced up maple sausage links are a great alternative to the ham.
- Cheese: Sharp cheddar cheese is my choice of cheese for this casserole as the sharpness from the cheese helps to cut the sweetness in this casserole. Swiss cheese is another great option.
How to Make Ham and Egg Casserole
- Grease a large casserole dish (9 by 13 or 2 quarts) with butter.
- Layer the bread, ham, and cheese inside the prepared dish.
- Whisk together the eggs, cream, mustard, maple syrup, and seasonings until well combined.
- Pour the egg custard over the mixture.
- Cover the casserole dish with plastic wrap and place in the fridge overnight. If you do not have time to refrigerate the ham and egg casserole overnight, press down the bread into the custard to "help" it absorbs the egg mixture and then bake for 10 minutes less than directed.
- In the morning, remove the plastic wrap bake.
- Serve with maple syrup on the side.
Recipe Tips and Notes
- Gluten-Free Modifications: If you need this be a gluten-free, use your favorite Gluten-Free Bread and be sure your ham is gluten-free as well.
- Baking Immediately: If you do not have time to refrigerate the ham and egg casserole overnight, press down the bread into the custard to "help" it absorbs the egg mixture and then bake for 10 minutes less than directed.
- Cranberry/Raisin Addition: If you want to have cranberries or raisins in this breakfast casserole without using raisin or cranberry bread, sprinkle raisins or cranberries over the ham and bread and add ½ teaspoon cinnamon to the egg custard.
