21 - 3 cups whole milk
22 - 1/4 teaspoon ground nutmeg
23 - 1/2 teaspoon salt
24 - 1/2 teaspoon white pepper

→ Assembly

25 - 12 no-boil lasagna noodles
26 - 2 cups shredded mozzarella cheese
27 - 1/2 cup grated Parmesan cheese
28 - Fresh basil leaves for garnish

# Directions:

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 large 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 over high heat, reduce to medium-low, and simmer uncovered for 20 to 25 minutes until lentils are tender and sauce has thickened.
04 - Melt butter in a saucepan over medium heat. Whisk in flour and cook for 1 to 2 minutes to form a roux. Gradually whisk in milk, stirring constantly to prevent lumps. Add nutmeg, salt, and white pepper. Continue stirring until sauce thickens and coats the back of a spoon, about 5 to 7 minutes. Remove from heat and set aside.
05 - Spread 1/4 cup lentil sauce in the bottom of a 9x13-inch baking dish. Arrange a layer of lasagna noodles over the sauce. Spread half the roasted vegetables, followed by half the remaining lentil sauce, and 1/3 of the béchamel. Sprinkle with 1/3 of the mozzarella. Repeat with another layer of noodles, remaining vegetables, remaining lentil sauce, another 1/3 of béchamel, and another 1/3 of mozzarella. Finish with remaining noodles, remaining béchamel, remaining mozzarella, and all the Parmesan.
06 - Cover the baking dish tightly with aluminum foil. Bake at 375°F for 30 minutes.
07 - Remove foil and bake for an additional 10 to 15 minutes until the cheese is golden brown and sauce is bubbling around the edges.
08 - Let the lasagna rest for 10 minutes before slicing to allow layers to set. Garnish with fresh basil leaves and serve warm.

# Expert advice:

01 -
  • The combination of smoky roasted vegetables and hearty lentils creates that umami richness usually reserved for meat-based lasagna
  • This lasagna actually improves overnight, making it the ultimate make-ahead dinner for busy weeks or feeding a crowd
02 -
  • Overcrowding the baking sheet when roasting vegetables will steam them instead of giving you those delicious charred edges, so use two sheets if needed
  • Letting the lasagna rest for 10 minutes after baking is the difference between a sloppy mess and those picture-perfect layers you see in magazines
03 -
  • No-boil noodles are my absolute preference because they absorb excess moisture from the vegetables and sauce, preventing that soupy bottom layer issue
  • Grating your own Parmesan instead of buying it pre-grated makes a shocking difference in how well it melts and distributes
