Open Lasagne with Mushrooms Ingredients
For the Béchamel Sauce
• Butter – Adds a rich base to create a velvety sauce; ensure it’s unsalted for better control over seasoning.
• Flour – Acts as a thickener to give the sauce its creamy consistency; use all-purpose flour or a gluten-free blend if needed.
• Milk – Provides creaminess; whole milk is ideal, but you can substitute with almond or oat milk for a dairy-free option.
• Nutmeg – A pinch adds warmth and depth; fresh grated will give the best flavor.
For the Open Lasagne Layers
• Lasagna Noodles – Use fresh or dried; fresh noodles require no boiling, while dried should be pre-cooked until al dente.
• Mushrooms – Bring an earthy flavor to the dish; try a mix of cremini and shiitake for a delightful variety.
• Onion – Adds sweetness and depth; yellow onions work beautifully, sautéed until fragrant.
• Garlic – Enhances the overall flavor profile; minced for best distribution in the layers.
For Topping
• Cheese – Mozzarella or Parmesan melts beautifully on top, bringing a golden-brown finish; for a vegan option, use cashew cheese.
• Fresh Herbs – Parsley or basil bring a burst of freshness; chop finely and sprinkle on top before serving.
