A lot of people like sweet brunch dishes. French toast, donuts, pancakes doused in syrup, desserts, and more. I lean a little to the savory side for my breakfast casserole ideas. I think it helps balance the booze consumption a little better. Hence this breakfast casserole. If you’ve never heard of a Croque Madame, it’s a fancy French grilled cheese with a fried egg on top. A little cheese, some béchamel, a touch of dijon, ham, and egg. I mean really what’s not to love? But let’s mess with that whole idea and put it all in a big baking dish!
Think of this as a chopped up saucy Croque Madame. The only difference is that the eggs are baked instead of fried. Full disclosure, this was my first time baking eggs. They didn’t bake evenly and I was bummed. (That ridiculously yellow egg is over hard, the others were still runny. Thank goodness!) Definitely cover your casserole loosely with some tin foil to prevent any single egg from cooking faster than the rest. You’re trying to get the whites cooked, the yolks will follow suit. But the sauce is awesome and this casserole is the bee’s knees. If you’re wearing of putting eggs on top, don’t fret! Leave ’em off and call it a Croque Monsieur Breakfast Casserole instead. Cause that’s the only difference in the sandwiches…the egg. Ta-da!

Croque Madame Breakfast Casserole
Ingredients
- 3 tablespoons all-purpose flour
- 3 tablespoons unsalted butter
- 2 cups whole milk yes, 2% is fine too
- ¼ teaspoon salt
- ⅛ teaspoon black pepper
- ¼ teaspoon ground nutmeg
- 2 ½ tablespoon Dijon mustard
- 6 cups French bread cut into 1/2-inch pieces about 1/2 a loaf
- 6 ounces Cabot White Oak Cheddar shredded and divided (or swiss cheese)
- 4 ounces thinly sliced black forest ham cut into bite sized pieces
- 4 eggs plus 2 more if necessary
Instructions
- Preheat oven to 350 degrees F.
- Melt butter in a medium saucepan over medium heat. Add flour and whisk to combine. Cook for 1 minute. Slowly pour in milk, while whisking constantly to prevent lumps. Cook sauce, whisking occasionally, until it begins to thicken, about 5 minutes.
- Add 1/2 cup cheese to the sauce, and whisk until melted. Add salt, pepper, nutmeg, and mustard; whisk to combine. Turn heat to low and keep sauce warm.
- Place half of the cubed bread in the bottom of the prepared baking dish, in an even layer. Top bread with half the ham and half the remaining cheese. Pour half the sauce evenly over the bread layer.
- Top sauce with remaining bread in an even layer. Top bread with remaining ham and sauce. Use a spatula to spread sauce over the casserole. Sprinkle top of casserole with remaining cheese.
- Use a spoon (or your fingers) to create 4 to 6 divots in the top of the casserole. Crack each egg and place one in each divot. This will help keep the yolks from touching the sides of the baking dish.
- Cover loosely with tin foil and bake for 20 minutes. Carefully remove tin foil and check to see if egg whites are done. If not, return casserole to the oven and bake for another 3 to 5 minutes until whites have set. (If you like your egg yolks over hard, leave the foil off the entire time.
- Remove from the oven and serve warm, cutting casserole so each serving has an egg on top.

I love breakfast casseroles and this is very unique with the eggs baked on top.
