# How-To Steps:

01 - Heat olive oil in a large, deep ovenproof skillet over medium heat. Add onion and cook for 3 to 4 minutes until softened.
02 - Stir in garlic, carrots, celery, and red bell pepper. Cook for 5 minutes until just tender.
03 - Add mushrooms and zucchini. Sauté for 5 to 6 minutes until softened and any moisture has evaporated.
04 - Sprinkle in smoked paprika, oregano, thyme, and chili flakes if using. Cook for 1 minute until fragrant.
05 - Stir in chopped tomatoes, tomato paste, red lentils, and vegetable stock. Season with salt and pepper.
06 - Bring to a simmer, cover, and cook gently for 20 to 25 minutes until lentils are tender and the mixture is thick but saucy. Stir in balsamic vinegar.
07 - Preheat oven to 350°F (180°C).
08 - Remove half the vegetable bolognese from the pan and set aside. Arrange a layer of lasagne sheets over the remaining sauce.
09 - Dollop half the ricotta over the lasagne sheets, then sprinkle with one-third of the mozzarella and Parmesan.
10 - Spread half the reserved vegetable bolognese over the cheese layer, top with more lasagne sheets, and repeat the layering: ricotta, mozzarella, Parmesan, and the final layer of vegetable bolognese.
11 - Finish with a final layer of lasagne sheets and sprinkle the remaining mozzarella and Parmesan on top.
12 - Cover pan with foil and bake for 25 minutes.
13 - Remove foil and bake for 10 to 15 minutes until golden and bubbling.
14 - Rest for 10 minutes before serving. Garnish with fresh basil leaves.

# Expert Suggestions:

01 -
  • It turns a mountain of vegetables into a comforting stack of cheesy goodness without a pile of dishes.
  • The red lentils dissolve into the sauce to create a texture so rich you might forget there is no meat.
02 -
  • Lentils act like sponges so if the sauce looks too dry before layering add a splash more water.
  • Tucking the pasta sheets completely under the sauce prevents those crunchy and uncooked edges.
03 -
  • Rinsing the red lentils under cold water removes the excess starch and leads to a cleaner sauce.
  • A tiny drop of liquid smoke can intensify the flavor if you want an even deeper profile.
