Creating Baked Eggs Napoleon is easier than you might think. Follow these steps to ensure you craft a delicious dish:

1. Preheat the Oven: Start by preheating your oven to 375°F (190°C).
2. Prepare the Puff Pastry: Roll out the puff pastry on a lightly floured surface. Cut it into strips, about 1 inch wide and long enough to form layers.
3. Bake Pastry Strips: Place the pastry strips on a baking sheet lined with parchment paper. Bake for 15 minutes or until golden and puffed up.
4. Prepare the Egg Mixture: In a mixing bowl, whisk together the eggs, heavy cream, cheese, garlic powder, salt, and pepper until fully combined.
5. Layer the Pastry: Once the pastry is cooled, create a base layer by placing several strips next to each other in a greased baking dish.
6. Add Fillings: If using, layer sautéed spinach, diced tomatoes, or bacon on top of the pastry layer. Pour a portion of the egg mixture over these fillings.
7. Add More Pastry Layers: Layer additional pastry on top of the egg mixture, followed by more egg mixture, repeating until all ingredients are used. Finish with a pastry layer on top.
8. Sprinkle Herbs: Top with any remaining cheese and sprinkle the fresh herbs over the final layer.
9. Bake: Place the dish in the oven and bake for 25-30 minutes. The egg should be set and the top golden brown.
10. Cool and Serve: Let it cool for a few minutes before slicing into squares.
