Its been a while since I changed up my lasagna. You all love the Baked Portabella mushrooms with garlic sauce, so I put them in a lasagna!

Mushrooms are marinated in a garlic, balsamic, soy marinade then baked, Meanwhile blend the garlic sauce and keep ready. Assemble the rest of the ingredients. Then start layering! Garlic white sauce, noodles, mushrooms, sauce, noodles, a layer of spinach and tofu ricotta, noodles and repeat. Top with vegan parmesan or vegan cheese and bake. Once baked, drizzle olive oil on top and add fresh herbs, slice and serve. 

For a quick meal, you can bake the portobello mushrooms until done, heat the garlic sauce to thicken then toss cooked pasta (fettuccine or penne) and fold in half of the sliced mushrooms and serve the rest on the side. Fold in some baby spinach when the sauce is simmering.

How to make this Creamy Mushroom lasagna without Nuts

  • Use my nutfree Cauliflower Alfredo or Pumpkin Alfredo instead of this nutty garlic white sauce. You might need a double serving. 
  • You can also use a my bechamel style flour sauce 
  • Definitely add some tofu ricotta or other vegan cheese between the layers as the nutfree sauces reduce in volume while baking. 
  • Add a layer of marinara and roasted veggies for a hearty Spinach mushroom lasagna.
  • No Boil noodles tend to absorb a lot of moisture during cooking and can sometimes dry the lasagna out sooner. Soak them in hot water for 2-3 mins, then use for less drying out.

Creamy Garlic Sauce:

  • 1.75 cups water
  • 1.5 tbsp flour, (rice flour for glutenfree)
  • 1 tsp salt

  • 3/4 tsp onion powder
  • 1/2 tsp ground mustard or miso, or both
  • 1/2 tsp black pepper
  • 1.5 tsp herbs, (1/2 tsp each of basil,thyme, ground sage)
  • 1 tbsp extra virgin olive oil
  • 2 tbsp nutritional yeast

Lasagna:

  • 12 no boil lasagna noodles, ***, glutenfree noodles for glutenfree
  • 4 oz baby spinach, , wilted on a skillet with 2 tbsp water if fresh, thawed if frozen
  • vegan parm, , breadcrumbs, vegan cheese for topping

Instructions 

  • Mix the mushroom marinade ingredients minus the water in a bowl. Place the whole mushrooms* in the lasagna baking dish. Drizzle the marinade all over the mushrooms. Use 1/4 cup of water or broth to rinse out the marinade bowl and our on the sides of the mushrooms.
  • Bake the mushrooms covered at 400 deg F (205 C) for 20 mins. Remove the mushrooms from the dish. Slice into 1/4 inch or less width, and set aside. Leave the juices in the dish.
  • Blend the garlic sauce ingredients until smooth. Taste and adjust salt and flavor.
  • Assemble: Add a ladleful of garlic sauce in the dish. Add a layer of noodles.
  • Then drizzle garlic sauce on the noodles, arrange sliced mushrooms on top, drizzle some sauce over the mushrooms, then add a layer of noodles.
  • Spread the sauce on the noodles, then add wilted (if fresh) or thawed spinach (if frozen). Sprinkle some red pepper flakes and a good pinch of salt over the spinach. Add some tofu ricotta** or drizzle some garlic sauce over the spinach.
  • Then another layer of noodles and sauce, mushrooms, noodles, and remaining sauce. Sprinkle some vegan parm all over or vegan mozzarella cheese shreds. (I use a mix of 3 tbsp breadcrumbs+ 3 tbsp vegan parm). Rinse out the garlic sauce blender/bowl with 1/2 cup water and pour on the sides of the lasagna dish. (Use 1 tbsp water if using precooked lasagna noodles.)
  • Cover tightly with foil and bake at 375 deg F (170C ) for 1 hour. Let it sit for 10 mins, then uncover. Sprinkle more vegan parmesan, extra virgin olive oil, herbs and pepper flakes. Then slice and serve. 
    Store refrigerated for upto 4 days.

Notes

Variation: Add a layer of marinara and some sauteed veggies in the middle. 
 
*If the mushrooms are too thick, then slice and add to the baking dish
 
** Quick Tofu Ricotta: Crumble 7 oz firm tofu in a bowl. Add 1/2 tsp garlic powder,1/2 tsp dried basil, 1 tsp extra virgin olive oil, 1 tsp apple cider vinegar, 1 tsp lemon juice, and 1/4 tsp salt &pepper. Mix and let chill for 15 mins, then adjust seasoning and use.  
 
Nutfree: Use my nutfree Cauliflower Alfredo or Pumpkin Alfredo or my bechamel style flour sauce instead of the garlic white sauce. You will need a double serving of the sauces. 
 
*** No Boil noodles tend to absorb a lot of moisture during cooking and can sometimes dry the lasagna out sooner. Soak them in hot water for 3 mins, then use for less drying out. 
If using regular lasagna noodles, cook them to al dente and then use.

    Exceptional recipe! Normally I would use โ€œno-boilโ€ lasagna noodles but this dish is better with cooked lasagna noodles. Otherwise, leftovers get a little dry due to the โ€œno-boilโ€ noodles soaking up all the liquid. Follow her tips! The flavor combinations are wonderful. My husband asks for it often. Another VeganRicha hit!!!

      Yay!!!

    This was so good! I was cooking for vegan + tomato allergy, so a white lasagna is great. I was also working with a cashew intolerance, so I used the cauliflower alfredo. Spinach and mushrooms are a classic combination and the marinated mushrooms were great with the creamy sauce. I have trouble finding reasonably-priced portobellos locally, so I used a mix of portobellos and criminis and was happy with the result. I will definitely be making it again!

      perfect, and tasty & healthy
