• 3 Tbs. butter / 45 g
• 1 large yellow onion, chopped
• ¼ cup red wine / 60 ml
• Salt and freshly ground black pepper, to taste
• For the Lettuce Filling & Assembly
• 2 large heads butter lettuce

• ¾ lb. Gruyère cheese, grated / 340 g, divided

Instructions
1. Prepare the Fillings
2. First, make the tomato sauce. Heat the olive oil in a large skillet over medium heat. Sauté the minced garlic until fragrant and golden. Stir in the tomato purée, chopped pimiento, bay leaves, and red wine. Season with salt and pepper. Bring to a simmer, then reduce the heat to low and let it cook gently for 1-2 hours, until the sauce has reduced by half and is quite thick. Remove the bay leaves and set aside.
3. While the sauce simmers, prepare the mushrooms. Place the dried mushrooms in a large bowl and cover them completely with hot water. Let them soak for at least 30 minutes until fully softened.
4. Carefully lift the mushrooms from the water, squeezing them gently. Meticulously wash each mushroom to remove any sand or grit. Strain the mushroom soaking water through a cheesecloth or coffee filter into a clean bowl and reserve at least 2½ cups / 600 ml.
5. Finely mince the rehydrated mushrooms. In a large skillet, melt the butter over medium heat and sauté the chopped onion until soft, about 5-7 minutes. Add the minced mushrooms, red wine, salt, and pepper. Pour in the 2½ cups / 600 ml of reserved mushroom water.
6. Bring the mushroom mixture to a simmer and cook, stirring occasionally, until most of the liquid has been absorbed and the mixture has the consistency of a thick paste or duxelles. Set aside.
7. Prepare the lettuce. Bring a large pot of water to a boil. Blanch the heads of butter lettuce for several minutes until they are completely wilted. Remove them from the water and drain thoroughly, squeezing out as much excess water as possible. Chop the lettuce finely. In a bowl, mix the chopped lettuce with just enough Béchamel sauce to bind it together (a few tablespoons) and season with salt.
8. Assemble and Bake
9. Preheat your oven to 400°F / 200°C. This recipe makes two crêpe cakes. To assemble the first cake, place one crêpe in the center of an ovenproof platter or shallow baking dish.
10. Create the layers. Spread a thin, even layer of the mushroom mixture over the first crêpe. Top with another crêpe and spread it with a thin layer of the tomato-pepper sauce. Add another crêpe, followed by a layer of the lettuce mixture. Place another crêpe on top and sprinkle it with a layer of grated Gruyère cheese.
11. Repeat the layering sequence (mushroom, tomato, lettuce, cheese) twice more, ending with a final crêpe on top. Pour a small amount of Béchamel sauce over the top crêpe and sprinkle lightly with paprika.
12. Assemble the second crêpe cake on another baking dish using the remaining in the same manner.
13. Combine the leftover grated Gruyère cheese with the remaining 1½ cups of Béchamel sauce and gently heat it in a saucepan until the cheese is melted and the sauce is smooth. Keep this cheese sauce warm for serving.
14. Bake the crêpe cakes for about 20 minutes, or until they are heated through and the cheese is bubbly. To serve, cut each cake into wedges and pass the warm Gruyère-Béchamel sauce separately.

Pro Tips
• To save time on assembly day, you can prepare the crêpes, tomato sauce, and mushroom filling up to two days in advance. Store them in airtight containers in the refrigerator.
• Squeeze the blanched lettuce very dry! Use your hands or press it between clean kitchen towels to remove all excess moisture, which prevents the crêpe cake from becoming watery.
• For the most stable and beautiful slices, ensure each layer of filling is spread thinly and evenly all the way to the edges of the crêpe.
• Let the finished cake rest for 5-10 minutes after baking. This allows the layers to set, making it much easier to cut clean wedges.
FAQ
Q: Is this mushroom crêpe cake a good source of vegetarian protein
A: Absolutely. This dish provides a substantial amount of vegetarian protein, primarily from the ¾ lb of Gruyère cheese and the milk-based Béchamel sauce. The mushrooms also contribute some protein, making it a very satisfying and hearty meat-free main course.
Q: Can I make this savory crêpe cake vegan
A: Adapting this recipe to be fully vegan requires several key substitutions. You would need to use a plant-based crêpe recipe, vegan butter, a high-quality vegan Gruyère alternative, and a Béchamel sauce made with plant milk and nutritional yeast. The final texture and flavor profile will be different but can still be delicious.
Q: What can I substitute for Gruyère cheese in this recipe
A: If you can’t find Gruyère, other good melting cheeses with a nutty, savory flavor are excellent substitutes. Consider using Comté, Emmental, or a high-quality aged white cheddar. For a milder option, a mix of provolone and Parmesan would also work well.
Q: How should I store and reheat leftover crêpe cake
A: Store any leftover crêpe cake tightly covered in the refrigerator for up to 3 days. To reheat, place individual slices on a baking sheet and warm in an oven at 350°F (175°C) for 10-15 minutes until heated through. This method helps preserve the texture of the layers better than microwaving.
