The Wonders of Mushroom Lasagna or Veganizing Ina Garten!

Vegan American Princess

Before we get into the deliciousness of mushrooms, we must discuss their health benefits because that will entice you to make this fabulous vegan mushroom lasagna with béchamel sauce!  Mushrooms have been around since prehistoric times.

Awesome Benefits of Mushrooms

The ancient Chinese believed that they imparted super-human strength while the ancient Romans considered them food of the gods. Mushrooms have been used in medicinal Chinese medicine for 3,000 years to boost immunity and fight diseases. They are rich in disease-fighting phytochemicals and studies have suggested that they may contribute to lower the risk of breast cancer and prostate cancer.  Mushrooms are high in many nutrients, including selenium, copper, niacin, riboflavin, thiamin, lysine, manganese, iron, potassium, linolenic acid and B-complex vitamins. Scientific studies show that certain mushrooms can hamper growth and spread of cancer cells, protect normal cells from environmental carcinogens, reduce side effects of chemotherapy, stimulate anti-tumor and anti-microbial activity and help halt HIV proliferation.  If that’s not a super food, I don’t know what is!  And miraculously, cooking them does not affect their nutritional value or properties.

The most popular varieties found in supermarkets are white button, portobella, crimini (baby portobellas), shiitaki, oyster, enoki and maitake.  They all have very different appearances and slightly different flavors and varying nutritional content and benefit.  Mushrooms are so versatile that you can add them to many dishes you’re preparing or make them the star as I did in the following recipe.

I was watching the Food Network recently and watched Ina Garten, The Barefoot Contessa, make a wonderful looking Mushroom Lasagna.  It was laden with all kinds of dairy products (butter, whole milk, Parmesan cheese) but I craved it so much that I decided to see if it could be veganized.  In place of the béchamel sauce that Ina created, I checked around for a vegan version and came upon one that looked really good at  So I combined the 2 recipes and changed it a bit and it came out rather delicious, if I do say so myself.

  1. This looks amazing and goes to show you can veganize just about any dish! I had no idea that cooking mushrooms does not affect their nutritional properties. That is, simply, amazing! I love the instructographics here.

  2. This looks amazing! Thanks for using our recipe. I am glad that it turned out. I would love to eat some right now!

  3. Helen Maxman says:

    Definitely going to make this recipe–it looks amazing! And now that I have 2 non-meat eaters in my house, I am sure this recipe will go over BIG!!!!!!

  4. I know who the first non-meat eater is? Who is #2?

  5. Andrea BAker says:

    Wow! Great recipe! I’m looking forward to trying it! Thanks!

  6. Victoria says:

    The recipe looks wonderful, but before I begin — is it even possible to preheat an oven to 753 degrees? If it is, baking a lasagne at that temperature for 45 minutes would burn it to a crisp!

    • Hi Victoria! I don’t know how or when the error in the recipe occurred. The correct temperature is 375 degrees! Thank you bringing it my attention and I will fix it asap! Thanks for reading and let me know how the mushroom lasagna comes out!
