Instructions
- Step 1
- Preheat the oven to 200°C (180°C fan) / 400°F / Gas 6.
- Step 2
- Heat olive oil in a large, ovenproof, deep frying pan or skillet over medium heat. Add the onion and garlic, sauté for 2 minutes.
- Step 3
- Add carrot, red pepper, mushrooms, and courgettes. Cook for 5–6 minutes until softened.
- Step 4
- Stir in smoked paprika, oregano, thyme, chili flakes, and tomato paste. Cook for 1 minute.
- Step 5
- Add canned tomatoes, soy sauce, red lentils, and vegetable stock. Bring to a simmer, cover, and cook for 15–20 minutes, stirring occasionally, until lentils are tender and sauce is thickened. Season with salt and pepper.

- Let stand for 10 minutes before serving. Garnish with fresh basil if desired.
Zusatztipps für die Zubereitung
To ensure the best results, use a high-quality ovenproof skillet and a whisk for the béchamel to keep it smooth. Covering the pan with foil during the first part of the bake is essential to trap steam and soften the lasagne sheets perfectly.
Varianten und Anpassungen
For a vegan version, simply substitute the dairy components with plant-based butter, milk, and cheese. If you're looking for extra depth, try adding a splash of red wine to the bolognese sauce while it simmers with the tomatoes.
Serviervorschläge
This rich lasagne pairs beautifully with a crisp green salad or warm garlic bread. It contains gluten, dairy, and soy, so for allergen-free versions, consider gluten-free pasta and tamari as a substitute for soy sauce.

Recipe Guide
- → Can I make this dish ahead of time?
Yes, assemble the entire dish up to 24 hours in advance and refrigerate. Bake for an additional 10-15 minutes if baking straight from the refrigerator.
- → Can I freeze leftovers?
Absolutely. Cut into portions, wrap tightly, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating at 180°C for 20-25 minutes.
- → What can I use instead of lasagne sheets?
You could use fresh pasta sheets, crepes, or even thinly sliced vegetables like courgette or aubergine for a lighter, gluten-free option.
- → How do I know when the lentils are cooked?
Red lentils typically take 15-20 minutes to simmer. They're done when tender but still hold their shape, not mushy. The sauce should also be thickened.
- → Can I add other vegetables?
Certainly. Spinach, aubergine, or butternut squash work beautifully. Add hearty vegetables when sautéing, and delicate greens like spinach just before layering.
- → Why use soy sauce in a vegetarian dish?
Soy sauce adds umami depth and richness, enhancing the savory flavors typically provided by meat in traditional lasagne. You can substitute with tamari or miso paste.
