Ingredients
  

6 large buttery croissants, torn into pieces

8 large eggs

2 cups whole milk

1 cup shredded Gruyère cheese

1 cup diced ham (or cooked bacon)

1 cup fresh spinach, chopped

1 teaspoon Dijon mustard

1 teaspoon garlic powder

1 teaspoon onion powder

Salt and pepper to taste

Fresh herbs (like parsley or chives) for garnish

Instructions
 

In a large mixing bowl, whisk together the eggs, whole milk, Dijon mustard, garlic powder, onion powder, salt, and pepper until well combined.

    Grease a 9x13-inch baking dish with butter or cooking spray.

      Spread the torn croissant pieces evenly in the baking dish.

        Sprinkle the diced ham (or bacon) over the croissants, followed by the chopped spinach and shredded Gruyère cheese.

          Pour the egg mixture evenly over the croissant layer, ensuring all pieces are soaked.

            Gently press down on the top layer to make sure the croissants absorb the egg mixture.

              Cover the baking dish with plastic wrap or foil and refrigerate overnight (or at least for 4 hours).

                Preheat the oven to 350°F (175°C). Remove the cover from the casserole and bake for 35-40 minutes, until the center is set and the top is golden brown.

                  Allow cooling for 5-10 minutes before slicing.
