Lasagna or Lasagne? Unraveling the Italian Naming

The distinction between “lasagna” and “lasagne” often causes a bit of confusion, especially outside of Italy. In authentic Italian culinary tradition, “lasagna” refers to a single sheet of pasta, while “lasagne” is the plural form, referring to multiple sheets of pasta or, more commonly, the layered baked dish we all know and love. So, when you’re talking about the complete dish with all its delicious layers of pasta, ragu, and béchamel, the correct Italian term is “lasagne.”

However, in many parts of the world, particularly in English-speaking countries, the word “lasagna” has become widely accepted and used to refer to the entire traditional Italian dish. While both terms are understood, opting for “lasagne” lends an authentic touch to your culinary vocabulary, especially when discussing traditional Italian recipes like this one.

Lentil Ragu Vs. Meat Ragu: A Flavorful Comparison

Beyond the obvious – one features lentils and the other meat – let’s delve into the fascinating differences that make each ragu unique. My traditional meat ragu, the foundation for many classic lasagnes and pasta dishes, typically consists of a simple soffritto (finely chopped carrots, onions, and celery), a blend of pork and beef mince, ripe tomatoes, a generous splash of red wine, and aromatic herbs. This combination simmers for hours, developing deep, rich flavors and a tender texture.

In contrast, this exquisite lentil ragu starts with the same foundational soffritto but replaces the meat with hearty Puy lentils and earthy mushrooms. The mushrooms are a game-changer, adding an incredible depth of umami flavor, a satisfying texture, and substantial bulk to the sauce. Combined with vibrant tomatoes, robust red wine, fragrant oregano, and pungent garlic, this lentil ragu achieves a complexity that rivals its meat counterpart.

While both ragus share a similar ingredient philosophy, their preparation times vastly differ. A meat ragu often requires at least two hours (if not more) of slow simmering to achieve perfection. This lentil ragu, however, comes together in under half an hour! This significant time-saving aspect means you can easily whip up this flavorful ragu from scratch even on busy weekdays, making it a perfect component for quick pasta dishes or, of course, this incredible lasagne.

Why Choose This Vegetarian Lasagne? Health, Taste, and Convenience

Opting for a vegetarian lasagne offers a myriad of benefits that extend beyond simply cutting out meat. This mushroom and lentil ragu lasagne is a fantastic choice for anyone looking to incorporate more plant-based meals into their diet without sacrificing flavor or satisfaction. Lentils are a powerhouse of nutrition, packed with protein, fiber, and essential minerals, making this dish incredibly filling and nutritious. The addition of mushrooms not only enhances the umami depth but also provides valuable vitamins and antioxidants.

From a health perspective, reducing red meat consumption can contribute to a healthier lifestyle. This lasagne provides a hearty and wholesome alternative that doesn’t feel like a compromise. It’s naturally lower in saturated fat and cholesterol than its meat-heavy counterparts, while still delivering that comforting, indulgent taste. Furthermore, for those managing dietary restrictions or simply seeking variety, this recipe is a versatile option that appeals to a wide range of tastes. Its rich flavors ensure that even the most dedicated meat-eaters will find themselves reaching for a second serving, often surprised by how deeply satisfying a meatless meal can be.

The convenience factor cannot be overstated. With a quick-cooking ragu and the option for make-ahead preparation, this lasagne is a busy cook’s dream. It’s perfect for meal prepping on a Sunday, providing delicious lunches or dinners throughout the week. Plus, it freezes beautifully, offering a ready-made meal solution for those hectic days.

Key Ingredients Spotlight: Crafting the Best Lentil Ragu Lasagne

Every great dish starts with quality ingredients, and this lentil ragu lasagne is no exception. Understanding the role each component plays will help you achieve perfection in every bite.

• Puy Lentils: These small, dark green lentils from the Le Puy region of France are renowned for their delicate, peppery flavor and firm texture. Unlike other lentils, Puy lentils hold their shape exceptionally well during cooking, preventing the ragu from becoming mushy. This characteristic makes them ideal for hearty sauces where a distinct texture is desired. Their earthy notes perfectly complement the mushrooms and tomatoes. If you can’t find Puy lentils, green or brown lentils can be used, but ensure they are cooked al dente.
• Mushrooms: Sliced mushrooms, whether cremini, button, or a mix of your favorites, are vital for adding a robust umami flavor and meaty texture to the ragu. As they sauté, mushrooms release their moisture and then brown, developing deep, savory notes that mimic the richness often found in meat sauces. They also significantly bulk out the ragu, ensuring a satisfyingly full lasagne.
• Fontina Cheese: For the béchamel, Fontina cheese is an excellent choice. This semi-soft Italian cheese melts beautifully, providing a wonderfully creamy texture and a nutty, slightly tangy flavor that elevates the béchamel. Its melting properties contribute to a smooth, luxurious sauce that binds the lasagne layers together perfectly. If Fontina is unavailable, Gruyere, white cheddar, or even a good quality provolone can be used as alternatives, offering a similar strong, melting cheese quality.
• Fresh Lasagne Sheets: While dried lasagne sheets are convenient, fresh pasta sheets offer a superior texture and tenderness. They cook more quickly and absorb the flavors of the ragu and béchamel more effectively, resulting in a more cohesive and melt-in-your-mouth experience. If using dried pasta, you may need to pre-boil them according to package instructions before assembling the lasagne.

How to Make Lentil Ragu Lasagne – A Detailed Guide

Preparing the Hearty Lentil Ragu

1. Start by finely chopping the carrot, celery, and onion – this classic Italian soffritto is the flavor base. In a large pan or Dutch oven, heat the olive oil over medium heat. Add the chopped vegetables and sauté them gently until they are soft and translucent, but not browned. This usually takes about 7-8 minutes. Patience here is key to developing a sweet, aromatic foundation.
2. Finely slice your mushrooms. Once the soffritto is tender, add the sliced mushrooms to the pan. Increase the heat slightly and fry the mushrooms for about 2 minutes, allowing them to release their moisture and begin to brown. This process deepens their flavor. (Refer to accompanying photos for visual guidance on steps 1 and 2).
3. Pour in the pureed tomatoes (passata), add the crushed garlic, and season with a pinch of salt and freshly ground black pepper. Stir everything together well, then add the red wine. Bring the mixture to a gentle simmer.
4. Let the ragu simmer gently for 10 minutes, allowing the flavors to meld and the alcohol from the wine to cook off. Then, stir in the pre-cooked Puy lentils. Simmer for another 2 minutes, ensuring the lentils are fully integrated and heated through. Turn off the heat.
5. Tip for the Ragu: If your sauce reduces too much and becomes overly thick before you add the lentils, simply add a small amount of water or vegetable broth to reach your desired consistency, then continue to simmer briefly. This ensures a moist and flavorful ragu for your lasagne. (Refer to accompanying photos for visual guidance on steps 3 to 6).

Crafting the Velvety Béchamel Sauce

6. In a separate saucepan, melt the butter over a low heat. Once fully melted, add the flour, stirring constantly to create a smooth paste, known as a roux. Continue to stir the roux for about 30 seconds to cook out the raw flour taste.
7. Gradually add half of the milk to the roux, whisking vigorously to prevent any lumps from forming. As the sauce begins to thicken, pour in the remaining milk and continue whisking until the béchamel reaches a thick, creamy consistency.
8. Remove the saucepan from the heat. Stir in the grated Fontina cheese (or your chosen substitute), Parmesan, a pinch of freshly grated nutmeg, and season with salt and pepper to taste. Continue stirring until all the cheese has completely melted into a smooth, luxurious sauce. Set aside.

Assembling and Baking Your Lasagne

9. Preheat your oven to 200°C (400°F) / Gas Mark 6. To begin layering, spread 1-2 tablespoons of the lentil ragu thinly over the bottom of your baking dish. This prevents the bottom pasta layer from sticking.
10. Arrange a single layer of fresh lasagne sheets over the ragu. You may need to trim or overlap some sheets to perfectly fit the dimensions of your dish.
11. Spoon another 2-3 tablespoons of the lentil ragu over the pasta, spreading it evenly. Follow this with 2-3 tablespoons of the Fontina béchamel sauce. Remember to reserve about one-quarter of the béchamel for the very top layer.
12. Repeat the layering process: pasta, ragu, béchamel, until all the pasta and ragu have been used. Aim for approximately 6 layers for a substantial lasagne. Finish the final pasta layer with the remaining one-quarter of the béchamel sauce, ensuring it’s spread generously across the top. (Refer to accompanying photos for visual guidance on steps 7 to 9).
13. Cover the baking dish tightly with aluminum foil. Bake in the preheated oven for 20 minutes.
14. After 20 minutes, remove the foil. Evenly scatter the torn mozzarella over the top of the lasagne. Return the uncovered dish to the oven and bake for an additional 10-15 minutes, or until the cheese has melted, turned a glorious golden-brown, and is bubbling invitingly.
15. Once baked, allow the lasagne to rest for 5-10 minutes before slicing and serving. This crucial resting period allows the layers to set, making for cleaner cuts and preventing the lasagne from falling apart. It’s fantastic served with a fresh green salad.

Tips for Success and Customization

• Make Ahead: This lasagne is an excellent make-ahead meal. Prepare and assemble it entirely, then cover tightly with plastic wrap and refrigerate for up to 2 days before baking. You might need to add an extra 5-10 minutes to the covered baking time if baking from chilled.
• Freezing: Leftovers can be frozen in individual portions for up to 3 months. Thaw overnight in the refrigerator and reheat in the oven or microwave until hot.
• Spice It Up: For a touch of heat, add a pinch of red pepper flakes to the ragu when sautéing the garlic.
• Herb Variations: While oregano is classic, feel free to experiment with other herbs like basil, thyme, or a bay leaf in your ragu for different aromatic profiles.
• Add More Veggies: Boost the nutritional content by adding finely diced zucchini, bell peppers, or spinach to the ragu alongside the mushrooms.
• Vegan Option: To make this recipe vegan, substitute the Fontina and Parmesan cheese with nutritional yeast for cheesy flavor, and use a plant-based milk and butter for the béchamel. Ensure your pasta sheets are egg-free.

Ingredients

For the lentil ragu

• 1 carrot
• 1 stalk of celery
• 1 white onion
• 2 2/3 cups (200g) mushrooms, sliced
• 2 cups (410g) puy lentils, pre-cooked
• 6.7 fl oz (200ml) red wine
• 2 cloves garlic, crushed
• 2 1/4 cups (500g) passata/pureed tomatoes
• 1 tbsp of olive oil

For the béchamel sauce

• 3 tbsp (50g) butter
• 1/3 cup (50g) flour
• 1 2/3 cup (400ml) milk
• 3.1 oz (90g) fontina cheese, grated
• Salt and pepper to taste
• 1 tbsp parmesan
• 4.4 oz (125g) mozzarella, torn
• 6-10 large fresh lasagna sheets

Instructions

• Finely chop the carrot, celery, and onion. Add the olive oil to a large pan and add the chopped vegetables, sauté gently until soft but not browned (around 7-8 minutes). Finely slice the mushrooms and add them to the sautéed vegetables.
• Fry the mushrooms for 2 minutes then add the pureed tomatoes/passata with the crushed garlic and a pinch of salt and pepper. Stir everything together and add the red wine.
• Let the ragu simmer gently for 10 minutes then add the lentils. If the sauce reduces too much, add a little water to the sauce before the lentils are added. Stir the lentils into the sauce and simmer gently for another 2 minutes, then turn the heat off.
• To make the béchamel sauce, add the butter to a saucepan over a low heat. Once melted, add the flour and stir into a paste. Stir the paste for around 30 seconds then add half of the milk, whisking to get rid of any lumps. Once it starts to thicken, add the rest of the milk and whisk until it thickens once more.
• Turn the heat off and add the grated cheese, Parmesan, nutmeg, and a pinch of salt and pepper. Stir the sauce until the cheese has melted and set aside.
• Preheat the oven to 200°C/400F/gas mark 6. Add 1-2 tbsp of lentil ragu to the bottom of a baking dish and spread it around. Add a layer of fresh lasagna sheets (you may need to cut some sheets to fit your dish). Add another 2-3 tbsp of ragu followed by 2-3 tbsp of béchamel sauce (keep 1/4 of the béchamel sauce for the top layer). Repeat this until all the ragu has been used up, ideally aiming for around 6 layers. Finish with the final 1/4 of béchamel sauce.
• Cover the lasagne with tin foil and bake in the oven for 20 minutes. Remove from the oven and top with the mozzarella, bake uncovered for 10-15 minutes until the cheese has melted, browned, and is bubbling.
• Let the lasagne rest for 5-10 minutes before serving.
