Easter is this weekend. If you are like us, you are probably making a big ham for Easter dinner. I look forward to all the leftovers! This Ham & Cheese Croissant Casserole is one of my favorite ways to use up all that leftover ham.

This breakfast casserole needs to be made at least 8 hours in advance. You can refrigerate it up to 24-hours in advance. The croissants need time to soak up all the yummy egg mixture.

Now, lets talk about croissants. The picture above is a croissant. You find them in the bakery at the grocery store or your local bakery. This recipe does NOT use refrigerated crescent rolls. Croissants and crescent rolls are NOT the same thing. Please make note to use croissants that you buy at the store.

We LOVED this casserole. It is great for breakfast, lunch or dinner. It is also great for overnight guests. Whip this up before bed and just pop it in the oven when you get up. Easy peasy!

  1. Hi! Do you think it would be ok to double this and put in a 9×13? If so, would cook times need to change? Thank you in advance!!

    1. I haven’t doubled this. But I would assume you would need to add 10 or 15 minutes to the baking time. You will just have to watch it and see how it looks.

  2. this sounds amazing!! we have local bakery that makes the best, softest cheddar cheese bagels. YES, I know bagels are not usually 'soft', but these are so good, you don't even need cream cheese. we usually get a couple of dozen on the weekends, so, I'm going to try this with a couple of the bagels instead of croissant's. I'll let ya know how it turns out.

  3. That's really tasty. I love ham and cheese in a croissant. Thanks for that neat idea. I think it would be great with some leftover spiral-sliced ham in there.

  4. The ingredients list calls for honey. However, I do not see it in the instructions. Do I mix it in with the eggs, half and half, etc?

  5. This looks wonderful! I apologize, but my math skills are sadly lacking. If I wanted to up this to serve more people (i.e.: 13×9 pan) would I double it or would that overflow? Thanks.
