Main Ingredients

4-6 pieces day-old croissants, torn into large pieces Day-old croissants soak up the custard better.
4 large eggs Provide structure and create a creamy custard.
1.5 cups whole milk (or unsweetened almond milk) Makes it soothing and rich.
1 cup shredded Gruyère or sharp cheddar Melty, savory, and irresistible.
1 cup diced ham or cooked bacon (optional) Adds a smoky, savory layer.
1 small onion, thinly sliced and caramelized Or use sautéed mushrooms for a vegetarian twist.
2 tablespoons Dijon mustard Brightens the flavors.
1 teaspoon dried thyme (or a tablespoon fresh thyme) Aromatic and classic.
to taste salt and black pepper
2 tablespoons melted butter For extra golden top and richness.
1/2 cup frozen peas or spinach (optional) For a healthier option.
1/4 teaspoon nutmeg (optional) For warmth.

Preparation

Preheat oven to 375°F (190°C). Grease a 9x13-inch baking dish with melted butter.
Tear the croissants into bite-sized pieces and layer about two-thirds of them in the dish.
Scatter the cheese, ham (or vegetables), and caramelized onion evenly over the croissant layer.
In a bowl, whisk eggs, milk, Dijon mustard, thyme, salt, pepper, and nutmeg until smooth.
Pour the custard over the croissant layers, gently pressing down to absorb the liquid.
Sprinkle remaining croissant pieces on top and brush melted butter over it.
Bake for 30-35 minutes until puffed and golden; let it rest for 5-10 minutes before serving.

Make-ahead: assemble in the baking dish and refrigerate overnight. Leftovers can be stored for up to 3 days.
