Air Fryer Vegan Lasagna

Air Fryer Vegan Lasagna has become one of my favorite go-to dinners when I want something hearty, comforting, and full of bold flavor. It's loaded with eggplant, mushrooms, roasted red pepper, and lentils in a rich tomato sauce, layered with tender noodles and silky cashew cream, and finished with a golden crunchy breadcrumb topping. I make it for family dinners, holiday gatherings, and potlucks because it always feeds a crowd and everyone loves it. Leftovers keep well in the fridge for up to 4 days and freeze beautifully for up to 2 months.

Instructions

  • Add the olive oil to a non-stick skillet and add the onion, eggplant, roasted pepper, mushrooms, and garlic. Cook for 10 minutes, or until the veggies start to soften.
    4 tablespoons extra virgin olive oil, 1 large onion, 1 small eggplant, 1 cup roasted red pepper, 2 cups mushrooms, 2 garlic cloves
  • Add the canned lentils, crushed tomatoes, vegetable broth, Italian seasoning, and spinach leaves. Mix well and cook at low-medium heat for 7 minutes. Season with salt and pepper.

  • Soak the cashew for at least 1 hour. Transfer the soaked cashews and water, olive oil, lemon juice, garlic clove, Italian seasoning, and salt to a high-speed blender and process until creamy (you may adjust the amount of water to get a bechamel-like consistency.
    1 cup raw cashews, 1 cup water, 2 tablespoons extra-virgin olive oil, 2 tablespoons lemon juice, 1 tablespoon Italian seasoning, ½ teaspoon sea salt, 1 garlic clove
  • Grease a baking dish and layer the pre-cooked lasagna noodles, lentil sauce, and cashew cream.

Notes

Here are a few things I've learned from making this recipe that'll help you get the best results every time.
  • Cook the veggies until they're actually soft: Give the onion, eggplant, mushrooms, and pepper the full 10 minutes in the skillet. Rushing this results in the eggplant having an unpleasant texture in the lasagna.
  • Simmer the lentil sauce properly: 7 minutes at low-medium heat, let the flavors meld, and the sauce thicken. A thin sauce will make the layers slide when you slice.
  • Soak the cashews long enough: Don't try to rush the soak to less than 1 hour, or the cream won't blend as smoothly. If you forget, a quick soak in boiling water for 20 to 30 minutes works in a pinch.
  • Adjust the cashew cream consistency: Add water gradually while blending, and stop when you reach a thick, pourable bechamel-like texture. Too much water will make it runny, and the layers won't hold.
  • Use pre-cooked noodles: The recipe calls for pre-cooked lasagna noodles, and that's important. Regular dry noodles won't cook through in the air fryer in 15 minutes.
  • Freeze in portions for easy meals: Slice the fully cooled lasagna into individual servings and freeze them in separate containers. They reheat quickly, and you'll always have a ready meal on hand.
