I’m admittedly a sucker for a great overnight breakfast casserole (check out all of my favorites here). But this recipe, with tangy cheddar cheese, tender chunks of ham and simple seasonings, exceeds all my expectations! This casserole is so easy to throw together the night before a big event, say Christmas morning, or Easter brunch. But it’s casual enough to whip up the night before so busy mornings run more smoothly.

Ingredients for Ham and Cheese Overnight Breakfast Casserole

No need to stress about finding obscure ingredients for this overnight breakfast casserole. You’ll find everything you need in your fridge or pantry! Here’s all you need:

  • eggs
  • milk
  • heavy cream or half and half
  • cubed ham
  • cheddar cheese
  • bread (day old or stale bread works best)
  • dashes of onion and garlic powder
  • salt and pepper
  • scallions (for garnish)

Using Block Cheese Instead of Pre-Shredded

I know it takes a bit more effort to shred cheese from a block instead of ripping open a package of pre-shredded, but trust me, it is so much better! Not only is the flavor more abundant, it melts better in the casserole. Definitely worth the extra step!

  2. Pour them into the prepared casserole dish.

Making this Breakfast Casserole the Day of

  • This recipe works best with dry or stale bread. If you don’t have any, throw some bread slices in the oven at a low temperature for about 5-10 minutes until they dry out a little.

    Could I use the same recipe to bake my ham in the oven?

    • Lisa Longley says

      I haven’t tried this in the oven, though I think you could. I would just make sure that you cover it so that it does not dry out.

    OMG, this looks so delicious…A perfect breakfast recipe infact…Thanks for sharing this Lisa

  3. Linda Muse says

    Served this recipe this morning to a group of women who have never heard of breakfast casserole much less eaten one! I kept to the recipe as much as possible (I live overseas and sometimes ingredients have to be substituted like not having cheddar cheese) and kept it simple. It was a big hit!

    • Lisa Longley says

      I’m so happy to hear this, Linda! Thank you for following along.

  4. Darla Meyer says

    Hello,

    If you bake, cool and then freeze to use in future, how do you prepare when you take it out of freezer? Just curious what temperature & how long it takes to warm it up? Or is microwave better?

    • Lisa Longley says

      Hi Darla! I haven’t tried that with this casserole. I would recommend thawing it in the refrigerator overnight and then baking it for 20 minutes, covered, at 350 degrees. Or, if you want to bake it right from frozen, I would recommend 40 minutes.
