Ingredients

  • For the Polenta Layers: 1 cup polenta (coarse cornmeal)
  • 4 cups vegetable broth
  • 2 tablespoons nutritional yeast
  • 1 tablespoon olive oil
  • Salt and pepper to taste
  • For the Zucchini: 3 medium zucchinis, thinly sliced lengthwise
  • For the Tomato Sauce:
  • 2 tablespoons olive oil
  • 1 medium onion, finely chopped
  • 4 garlic cloves, minced
  • 1 can (28 oz) crushed tomatoes
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • 1/2 teaspoon red pepper flakes (optional)
  • Salt and pepper to taste
  • For the Cashew Cheese:
  • 1 cup raw cashews, soaked for at least 4 hours or overnight
  • 1/4 cup nutritional yeast
  • 2 tablespoons lemon juice
  • 1/4 cup water (add more if needed)
  • 1 garlic clove
  • Salt to taste
  • Additional: Fresh basil leaves for garnish

Equipment

  • Large saucepan
  • Medium skillet
  • Food processor or high-speed blender
  • Baking dish (9×13 inches recommended)
  • Sharp knife and cutting board
  • Mixing bowls
  • Measuring cups and spoons
  • Spatula or wooden spoon

Instructions

  1. Prepare the polenta: In a large saucepan, bring the vegetable broth to a boil. Gradually whisk in the polenta and reduce heat to low. Cook, stirring frequently, for about 25-30 minutes or until thickened and creamy. Stir in the nutritional yeast, olive oil, salt, and pepper. Spread the cooked polenta evenly onto a parchment-lined baking sheet to about 1/4-inch thickness. Let it cool completely and firm up, then cut into rectangular sheets roughly the size of your baking dish.
  2. Make the tomato sauce: Heat olive oil in a skillet over medium heat. Add onion and cook until translucent, about 5 minutes. Add garlic and cook for another minute until fragrant. Pour in crushed tomatoes, oregano, basil, red pepper flakes (if using), salt, and pepper. Simmer uncovered for 15-20 minutes, stirring occasionally, until the sauce thickens slightly.
  3. Prepare the cashew cheese: Drain soaked cashews and add them to a food processor along with nutritional yeast, lemon juice, garlic, salt, and water. Blend until smooth and creamy, adding more water a tablespoon at a time if needed to reach a spreadable consistency.
  4. Prepare the zucchini: Using a sharp knife or mandoline, slice zucchinis lengthwise into thin strips about 1/8-inch thick. Lightly salt the slices and lay them on paper towels to draw out excess moisture for about 10 minutes. Pat dry before assembling.
  5. Assemble the lasagna: Preheat your oven to 375°F (190°C). In your baking dish, spread a thin layer of tomato sauce on the bottom. Layer polenta sheets, then a layer of zucchini slices, followed by dollops of cashew cheese and more tomato sauce. Repeat layers until all ingredients are used, finishing with a generous layer of tomato sauce and cashew cheese on top.
  6. Bake: Cover the baking dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 10-15 minutes until the top is golden and bubbly.
  7. Rest and serve: Let the lasagna cool for at least 10 minutes before slicing. Garnish with fresh basil leaves and enjoy!

Tips & Variations

To prevent soggy zucchini layers, make sure to salt and pat dry the slices before assembling.

Tip: You can prepare the polenta and cashew cheese a day in advance to save time on the day you plan to serve.

Variation: Swap zucchini with eggplant or thinly sliced sweet potatoes if you prefer a different vegetable layer.

Additional flavor: Add sautéed mushrooms or spinach to the layers for an extra nutrient boost and earthiness.

Spice it up: Incorporate fresh chopped chili or smoked paprika into the tomato sauce for a smoky, spicy twist.
