Ingredients

Scale

Vegetables

  • 2 medium Yellow onions (Thinly sliced)
  • 3 cloves Garlic (Minced)
  • 8 ounces Mushrooms (Thinly sliced)
  • 4 cups Spinach (Packed tightly)

Fats & Oils

  • 2 tablespoons Vegan butter (Or olive oil)

Liquids & Broth

  • 2 tablespoons Balsamic vinegar or red wine
  • 1 cup Broth (Vegetable broth recommended for sauce)
  • 2 cups Broth or water (For cooking pasta)

Dry Goods & Pantry

  • 1 cup Raw cashews (Soaked for at least 20 minutes)
  • 8 sheets Lasagna pasta sheets (Broken into pieces)
  • 2 tablespoons Nutritional yeast

Seasonings & Spices

  • 1 teaspoon Dried thyme
  • 1 teaspoon Salt (plus 1 teaspoon more for sauce, adjust taste)
  • 1 teaspoon Black pepper (plus a dash more for sauce)
  • 1 teaspoon Italian seasoning
  • 1 teaspoon Miso
  • 2 tablespoons Lemon juice
  • 1 teaspoon Red pepper flakes (Optional)


Instructions

  1. Caramelize Onions: Heat a skillet over medium heat and add the vegan butter. Add the thinly sliced onions and cook for about 8 minutes, stirring occasionally, until translucent and fragrant.
  2. Add Garlic and Seasonings: Stir in minced garlic, dried thyme, salt, and black pepper. Continue cooking until onions develop a golden color.
  3. Deglaze with Vinegar or Wine: Pour in balsamic vinegar or red wine and mix well. Cook another 5 minutes until onions caramelize. Reserve three-quarters of this mixture separately for garnish.
  4. Cook Mushrooms: Add the sliced mushrooms to the skillet and cook for 1-2 minutes until tender.
  5. Prepare Cashew Sauce: In a blender, combine soaked cashews, 1 cup vegetable broth, lemon juice, nutritional yeast, Italian seasoning, salt, miso, and black pepper. Blend until smooth and creamy.
  6. Combine Sauce with Vegetables: Pour the creamy cashew sauce into the skillet with the onion and mushroom mixture. Gently fold in the broken lasagna sheets and 2 cups of broth or water.
  7. Simmer Covered: Cover the skillet and cook for 12-15 minutes, stirring occasionally, until the pasta is cooked through and has absorbed the sauce.
  8. Add Spinach: Fold in the packed spinach gently, then cover and let sit for 3 minutes to allow the spinach to wilt.
  9. Garnish and Serve: Top the skillet lasagna with the reserved caramelized onion mixture and optionally sprinkle with red pepper flakes for a bit of heat. Serve warm.

Notes

  • Soak cashews for at least 20 minutes to ensure a smooth sauce texture.
  • Adjust salt and pepper according to taste, especially since broth and miso add saltiness.
  • If you prefer a spicier dish, increase the red pepper flakes or add a dash of cayenne pepper.
  • This recipe is completely vegan and dairy-free, making it suitable for vegan diets.
  • If you have gluten intolerance, use gluten-free lasagna sheets.
  • Make sure to break lasagna sheets into smaller pieces for even cooking in the skillet.
