Roasted vegetables, tomato sauce and cashew-tofu ricotta make a lasagna with plenty of depth between its layers. Eggplant and mushrooms bring a savory richness, zucchini lightens the bite, and basil gives the tomato a fresh finish. A warm slice feels generous without needing a heavy cheese topping.

We love the two textures in the filling. Smooth cashew cream coats the crumbled tofu, while spinach and parsley keep little green flecks through the layer. That combination gives the ricotta a creamy feeling with enough structure to sit comfortably between the noodles.

This is a recipe to give some time: cashews soak, vegetables roast, sauce simmers and the baked dish rests before slicing. Several jobs can overlap. Let that planning work for you, while tenderness and the settled layers remain more important than fitting every stage into an exact clock.

Roasting Makes the Layers More Flavorful

Use separate trays so zucchini can finish earlier while eggplant, mushrooms and onion have time to brown. Roasting lets moisture escape and concentrates the vegetables’ flavor. Crowding them into one deep pile gives the lasagna wetter layers and fewer savory browned edges.

Let excess steam escape after roasting. The vegetables should be tender before assembly, because the covered bake is not a reliable way to finish firm eggplant tucked between sauce and noodles. Thin zucchini ribbons and comfortably sized vegetable pieces also make a slice easier to eat.

Smooth Cream, Gentle Tofu Texture

Drain the soaked cashews and blend their cream completely smooth before folding it into tofu. Nutritional yeast and miso bring a savory depth, with lemon keeping the mixture from feeling heavy. Pause to scrape the blender rather than accepting a grainy cream.

Leave some tofu texture as you fold in spinach and parsley. You are making a creamy filling, not blending every ingredient into one sauce. Sunflower seeds can replace cashews with a different, more seed-like flavor, and also make a useful creamy base for vegetable sauces beyond lasagna.

Let the Noodles and Sauce Meet Well

Cook the gluten-free noodles as their package directs, stopping just short of full tenderness. Lay them flat after draining so they do not stick together. Check noodle, plant milk and miso labels for gluten-free suitability; their names alone do not settle that question.

Spread sauce across the bottom and finish with sauce on top so the noodles have moisture where they need it. A few tablespoons of reserved pasta water around the edges can help if the assembly looks dry. Keeping a whole cup in reserve does not mean pouring the whole cup into the dish.

A Rich Meal With an Optional Finish

Tofu and cashews provide meaningful plant protein, with vegetables and tomato contributing fiber and variety. Olive oil is part of the recipe’s richness. Optional vegan mozzarella makes a different top and is separate from the default nutrition estimate; the lasagna is complete without it.

For a beautiful serving, give the baked dish at least twenty minutes to settle before cutting. The filling and sauce hold more comfortably as the hottest steam subsides. Add fresh basil and parsley, then bring a crisp green salad beside it for a cool contrast to the warm layers.

Planning That Makes the Meal Easier

Prepare components ahead when helpful, keeping soaked cashews refrigerated and handling cooked foods promptly. After baking, chill leftover portions in shallow containers at 40°F (4°C) or below and use within three days, or freeze cooled individual portions for another meal.

Reheat covered to 165°F (74°C), with a little water to protect the noodles from drying. A brief uncovered finish restores the top. Individual portions make reheating easier and give another dinner the same comfort without needing to build the whole lasagna again.

Equipment

  • 9-by-13-inch baking dish
  • two baking trays
  • parchment and foil
  • Saucepan
  • noodle pot
  • colander
  • Blender
  • mixing bowl
  • spatula
  • knife

Method
 

  1. Cover the raw cashews with water and soak for 4–6 hours, refrigerating during the soak. Drain well before blending. Soak and blend the dates separately as needed for the sauce.
  2. Heat the oven to 425°F (220°C) and line two trays. Spread zucchini ribbons on one and the eggplant, mushrooms, onion and garlic on the other. Distribute the vegetable olive oil, salt, pepper, oregano, fennel and paprika between them. Roast zucchini for about 12 minutes; roast the other vegetables for 28–32 minutes, until tender and browned. Let excess steam escape.
  3. Combine passata, tomato paste, blended dates, balsamic vinegar, sauce salt and pepper, dried basil and oregano and optional chili flakes in a saucepan. Simmer gently for 25 minutes, stirring occasionally. Stir in the fresh basil near the end; blend briefly only if you prefer a smoother sauce.
  4. Blend drained cashews, oat milk, nutritional yeast, lemon juice, miso, ricotta salt, garlic powder and nutmeg until smooth. Pause and scrape the blender as needed.
  5. Crumble the pressed tofu into a bowl. Fold in the chopped spinach, parsley and cashew cream, leaving a little tofu texture.
  6. Cook the gluten-free lasagna noodles in boiling water as their package directs, stopping just short of full tenderness. Reserve the measured cup of pasta water, then drain and lay the noodles flat on parchment so they do not stick together.
  7. Reduce the oven to 375°F (190°C). Spread a thin layer of sauce in a 9-by-13-inch baking dish. Layer noodles, ricotta filling, roasted vegetables and sauce, repeating until used. Finish with sauce and optional vegan mozzarella. Spoon a few tablespoons of the reserved pasta water around the edges if needed; reserve the rest rather than flooding the dish.
  8. Cover with parchment and foil and bake for 35 minutes. The center should be heating through and the edges bubbling.
  9. Remove the covering and bake for another 15–18 minutes until bubbling throughout and lightly golden on top. Extend gently if the center is not yet hot.
  10. Let stand for at least 20 minutes before slicing so the layers settle. Garnish with fresh basil and parsley and cut into 8 portions.

Notes

Timing: The planning estimate allows 45 minutes preparation, about 85 minutes combined roasting and baking, four hours minimum cashew soaking and a 20-minute rest. Sauce and noodle cooking can overlap with roasting, and preparation can overlap with soaking; do not rush tenderness or the final rest to fit a clock.
Gluten-free: Verify noodles, plant milk, white miso and optional vegan cheese.
Ricotta: Blend the cashew portion fully smooth before folding into tofu.
Optional cheese: The mozzarella topping is separate from the default nutrition estimate; the lasagna also works without it.
Pasta water: Reserve 1 cup, but add only a few tablespoons around the edges as needed; unused reserved water is not consumed.
Swaps: Almond milk gives a different nut flavor, and finely chopped kale is firmer than spinach. Sunflower seeds can replace cashews with a different flavor and texture.
Make ahead: Chill cooked portions promptly in shallow containers.
Storage: Refrigerate at 40°F (4°C) or below for up to three days, or freeze individual cooled portions. Reheat covered to 165°F (74°C), adding a little water to keep the noodles moist. A brief uncovered finish restores the top.
Larger batches: When increasing the yield, use additional 9-by-13-inch dishes and roast vegetables in uncrowded batches. Keep the layer depth similar and use the bubbling, tenderness and hot-center cues; a larger batch may need more oven time.
