Ingredients

• 6 large eggs

• 1 tablespoon butter or nonstick spray for greasing
• Fresh parsley, for garnish

How to Make Savory Croissant Bake

Grease a 9×13-inch baking dish with butter or spray. Slice croissants in half and layer the bottoms in the dish. Add ham slices and Gruyère cheese, then cover with the croissant tops. In a mixing bowl, whisk together eggs, milk, Dijon mustard, salt, and pepper. Pour the custard evenly over the croissants, pressing gently so they soak. Cover and refrigerate for 30 minutes or overnight. Preheat oven to 375°F (190°C), then bake uncovered for 35–40 minutes until puffed and golden. Rest for 5 minutes before slicing and garnish with parsley.

Instructions:

1. Prepare the Dish: Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
2. Layer the Croissants: Slice croissants lengthwise and arrange the bottoms in the dish, overlapping slightly to cover the base.
3. Add Ham & Cheese: Layer ham slices evenly over croissants, then sprinkle shredded Gruyère on top, reserving some cheese for garnish. Place the croissant tops over the layers.
4. Whisk the Custard: In a large bowl, whisk eggs, milk, Dijon mustard, salt, and pepper until smooth. The Dijon adds depth that complements the cheese.
5. Assemble the Bake: Pour the custard evenly over the croissant layers. Gently press with a spoon so the croissants absorb the mixture. Cover and refrigerate for at least 30 minutes, or overnight for a deeper flavor infusion.
6. Bake to Perfection: Remove the dish from the fridge and let it sit for 10 minutes. Bake uncovered for 35–40 minutes until the custard sets, croissants puff up, and the top turns golden brown.
7. Rest & Garnish: Let the bake cool for 5 minutes, then sprinkle with remaining Gruyère and fresh parsley. Slice neatly and serve warm.

The finished dish is rich, savory, and beautifully layered—an indulgence that looks as impressive as it tastes.
