    Kittencalskitchen's Note:

    This is a wonderful vegetarian dish! If desired, regular mushrooms may be substituted for the portabellos, but the regular mushrooms should be sautéed first to release any moisture, To make things easier, you may Classico pasta sauce for this recipe or just use your own favorite sauce --- prep time includes boiling the pasta.

      Excellent! I do make a few modifications, basically because we like lots of cheese. I use a full 8 ounces of feta and 3 cups of shredded mozzarella in the lasagna itself (about 12 ounces). I up it to two eggs so it will bind well. I don't increase the amount of spinach. I put an extra 1 cup of mozzarella on the top, but not until it is done baking for about 45 minutes. I'm not sure why I need to bake it longer than the recipe states. After it is fully heated through and the mushrooms are cooked, I remove the cover and sprinkle the 1 cup (4 ounces) of mozzarella on top. Then I bake about 10 minutes longer until the mozzarella is melted. This has become a go-to recipe and is made every 2 or 3 weeks.

      I have discovered that substituting a 24 ounce jar of Prego chunky vegetable, mixed with 1 Tablespoon of balsamic vinegar works as well for us as making the sauce from scratch -- and is much quicker.

      I have also used white button mushrooms instead of portabella but it is essential to cook them first.

      If time permits, I also cook the portabellas first. I just like it a little bit better this way, but it is not essential.

      Thank you for the yummy, and easy, lasagna recipe

      This was very very good! I used 4 large mushroom caps which was perfect. Made the sauce exactly as written and liked it very much. I hold off on the 5th star because I didn't have enough sauce. I topped with 1/2 another can of diced tomatoes. I also used closer to 1 3/4 cup feta and 3 cups mozzarella. The cheese still wasn't truly noticeable. Everything melded so well! Spinach hating Fiance scarfed it down like crazy, as did I. This is a keeper with a couple small modifications! Try it!

      Wonderful! This doesn't taste like anything vegetarian that I would expect - it tastes great! As another layer to my lasagna I add provencal roasted olives (seasoned of course) and the combination beats any real-meat lasagna I've had in a restaurant.
