# 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 degrees Fahrenheit.
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 a 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 another 10 to 15 minutes until golden and bubbling.
14 - Rest for 10 minutes before serving. Garnish with fresh basil leaves.

# Top Tips:

01 -
  • The smokiness from the paprika transforms ordinary vegetables into something that feels indulgent and complex, like a secret only home cooks know.
  • Youll feel genuinely clever when you pull this from the oven in a single pan, saving yourself from the dreaded lasagne cleanup marathon that normally follows.
02 -
  • The first time I made this, I skipped removing half the sauce before layering and ended up with soggy lasagne sheets that never properly cooked, so dont skip that crucial step.
  • I discovered that pressing the lasagne sheets gently into the sauce helps them absorb moisture evenly, preventing those disappointing crunchy corners that can ruin the experience.
03 -
  • After trying countless versions, I found that grating rather than dicing the carrots lets them melt into the sauce, removing any textural distraction while still providing sweetness and nutrition.
  • Splash a little water on top of the final layer of lasagne sheets before adding the cheese, ensuring they cook perfectly even at the very top of the dish.
