HAM SWISS BREAKFAST CASSEROLE
We love doing breakfast for dinner or making this casserole when we have guests in town. It’s easy, cheesy, and full of flavor!
INGREDIENTS
- CROISSANTS – These can be found in the bakery or deli section of your grocery store. Crescent dough from the can cooked does not yield the same result.
- HAM – I prefer a diced ham from a ham steak or cooked ham. I don’t love deli ham (like for sandwiches) as much but it can’t be used.
- SWISS CHEESE – I love the flavor this gives the casserole but Gruyere, cheddar, or Monterey Jack cheese can be used.
- EGGS
- DIJON MUSTARD – This adds a special flavor and tang to the dish.
- HALF AND HALF – You can use milk or all cream if you want.
- GREEN ONIONS
HOW TO MAKE THIS
-
-
Grease a 9×13 baking dish. Layer half the croissants, half the ham, and half the cheese. Repeat layers.
-
In a large bowl, whisk together the eggs, half and half, green onions, mustard, salt, and pepper.
-
Pour mixture over the croissant mixture making sure it is all covered. Cover with foil and refrigerate for at least 8 hours or overnight.
-
When ready to bake, remove casserole from fridge and let sit at room temperature while the oven preheats. Preheat oven to 350 degrees. Bake covered for 30 minutes. Remove foil and bake another 25-35 minutes or until top is browned and the center is set. Eat warm. Garnish with more green onions if desired.

What if I leave in fridge for only 5 hours
That’s totally fine
Can I get clarification on the amount of cheese? This says 2 cups (8 ounces), but wouldn’t 2 cups be 16 ounces?
No cheese is measured differently by weight not in fluid cups.
Does this freeze well after cooking?
Yes!
Could this casserole be baked in a toaster?
Sure!
I LOVE this casserole!! But I do exactly what they say NOT to do! I use 1/2 pound shaved ham. Just sprinkle it on each layer. And it is WONDERFUL! I use Swiss or Cheddar And it comes out great with either!! I also divide it into single portions and put it in the freezer. So easy to defrost in the microwave on Timed Defrost (30% power).
Great tip!
This is delicious as shown. However, I was wondering if I could use shrimp instead of ham.
Thank you.
Of course!
Should you toast the croissants first? I want to make a day ahead and keep it in the refrigerator until ready to bake.
Will the croissants turn out mushy if they’re not stale or toasted?
Thanks
You don’t need to toast. You are fine to soak it the day before.
You don’t need to toast it and it can soak the day before.
This is so easy to put together and so delicious. Thank you for the recipe.
This looks Fantastic, This is a MUST try this week.

This looks great & I will try it. But since the accepted ratio is 1 tablespoon of dairy or water per egg, I’ll use at most 2/3 of a cup of half & half. I don’t understand why many breakfast casseroles
call for so much more dairy. I love eggs, but not eggy milk. 😊
I agree! I don’t love eggy milk.
