# How-To Steps:

01 - Preheat the oven to 425°F.
02 - Toss eggplant, zucchini, red and yellow peppers, onion, and garlic with olive oil, smoked paprika, salt, and black pepper. Spread on a baking sheet and roast for 25 minutes until vegetables are tender and lightly charred. Reduce oven temperature to 375°F.
03 - Combine lentils, crushed tomatoes, tomato paste, oregano, basil, vegetable broth, balsamic vinegar, and chili flakes in a saucepan. Bring to a boil, reduce heat, and simmer uncovered for 20–25 minutes until lentils are tender and sauce is thickened.
04 - Melt butter in a saucepan over medium heat. Whisk in flour and cook for 1–2 minutes. Gradually whisk in milk, stirring constantly to avoid lumps. Add nutmeg, salt, and white pepper. Cook, stirring, until thickened; set aside.
05 - Spread 1/4 cup lentil sauce in the bottom of a 9x13-inch baking dish. Layer with lasagna noodles, then half the roasted vegetables, half the lentil sauce, and 1/3 of the béchamel. Sprinkle with 1/3 of the mozzarella. Repeat layers. Top with remaining noodles, béchamel, mozzarella, and Parmesan.
06 - Cover with foil and bake at 375°F for 30 minutes.
07 - Uncover and bake for another 10–15 minutes until golden and bubbling. Rest for 10 minutes before slicing. Garnish with fresh basil leaves.

# Expert Tips:

01 -
  • The smoky roasted vegetables add incredible depth that mimics meaty richness without any animal products
  • Lentils create a protein-packed sauce that feels substantial and satisfying, not like a compromise
  • This lasagna actually tastes better the next day, making it perfect for meal prep or make-ahead dinners
02 -
  • The resting period is nonnegotiable, it lets the lasagna set so slices hold their shape instead of sliding into a messy mound
  • If your lentil sauce looks too thick, add a splash of water or broth before assembling, the noodles need moisture to cook properly
  • Béchamel can seize up if the milk is too cold, let it come to room temperature before whisking into the roux
03 -
  • Roast vegetables until they have visible char spots, that smoky flavor is what makes this lasagna extraordinary
  • Use a box grater to shred your own mozzarella instead of buying pre-shredded, it melts so much better
  • Let the béchamel cool slightly before assembling, it will be easier to spread evenly over the noodles
