Description

This warm, gooey, cheesy casserole is perfect for brunch, holiday mornings, or even weeknight dinners. It’s easy to make, customizable, and a great way to repurpose leftovers.

Ingredients

Scale

6 large or 8 medium croissants, slightly stale
2 cups diced ham (~300g)
2 cups shredded cheese (~200g), Swiss or Gruyere recommended
6 large eggs
2 cups whole milk (~475ml)
1 tbsp Dijon mustard
Salt and pepper to taste
Optional: Fresh herbs like chopped chives or parsley for garnish

Instructions

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray.
Chop the croissants into bite-sized pieces and place them in a large mixing bowl. Add the diced ham and half of the shredded cheese, and toss to combine.
In a separate bowl, whisk together the eggs, milk, Dijon mustard, salt, and pepper until smooth and well combined.
Pour the custard evenly over the croissant mixture in the bowl, then gently toss until everything is coated. Transfer the mixture to the greased baking dish and spread it out evenly. Sprinkle the remaining cheese over the top.
Bake for 35-40 minutes, or until the casserole is golden brown, puffed, and set in the center. Cover loosely with foil if the top is browning too quickly.
Let the casserole rest for 5-10 minutes before slicing. Sprinkle with fresh herbs, if desired, and serve warm.

Notes

[‘Stale croissants work best as they absorb the egg mixture without turning soggy.’, ‘You can customize the recipe by adding sautéed spinach, mushrooms, or caramelized onions for a veggie boost.’, ‘Prep the casserole the night before and bake it in the morning for an easy brunch.’, ‘Let the casserole rest for 5-10 minutes after baking to set properly.’]
