Mushroom Masters: A Tournament of Taste is back for year two!

I was delighted to be asked to participate again after having so much fun with my Portabella Pizza recipe last year. Things got wild. Last year’s challenge is a big reason why I now love (and crave!) mushrooms as much as I do. I really didn’t fall in love with mushrooms until I started experimenting with them in the kitchen.

Sometimes those strange little things just need to grow on you like…fungi…?

Check out these cool mushroom facts:

  • Mushrooms are the only item in the produce aisle with vitamin D.  Winter’s coming, eat up!
  • Mushrooms are low in calories, fat free, and can be an effective substitute for meats thanks to their hearty and fulfilling nature.  I would concur.
  • Mushrooms are a source of selenium and ergothionene, antioxidants that play a role in immunity. Don’t be a sicky this Winter and eat up.
  • Mushrooms are a kitchen staple: they can star as the feature ingredient, or pair with any dish. They are like a little black dress, in other words.

 

Tastespotting is hosting the event once again along with Mushrooms Canada, Australian Mushroom Growers Association, and The Mushroom Council. Twelve of us food bloggers from Canada, US, and Australia were asked to compete in this challenge and were offered a bit of compensation for our time and food costs. We are now in the 4th and final week of the challenge.

I was assigned to the final week’s Appetizer challenge! Also participating in this appetizer challenge are  two very talented bloggers- Elana of Elana’s Pantry and Ellie of Kitchen Wench.

To be honest, I thought my mushroom creativity was maxed out with last year’s Portabella Pizza, but this Mushroom Walnut Pesto Tart is hands down the best mushroom recipe I’ve ever made. I’m so excited to share it with you after sitting on the recipe for a few weeks.

Given my recent infatuation for vegetables in my pesto, I thought it would be fun to make a mushroom walnut parsley pesto as a base for a tart. I really had no idea how it would turn out so I prayed to the culinary gods for a miracle.

IMG_1836-2

For the pesto, I processed together garlic, toasted walnuts, extra virgin olive oil, fresh parsley, S & P, and the sautéed mushrooms. I was a bit worried that the mushrooms would taste weird in a pesto (shame on me, I know), but the flavours just worked so well. If you don’t want to make a tart you can always use this pesto with a pasta dish or spread over some crostini. Or you know, the spoon to face method worked for me quite well.

Step aside roasted tomato basil pesto, there’s a new fav pesto in town.

Mushroom Walnut Pesto Tart

By

Calling all mushroom fans!

My award-winning pesto tart took home first-prize in a Mushroom Canada competition a few years ago. It takes a bit of time to prepare, but the wait is worth it once you sink your teeth into your first crispy, savory bite. If you don’t want to make a phyllo tart you can simply spread the pesto onto crostini or try tossing the pesto with pasta and sauteed mushrooms for an elegant dinner.

Yield
12-15 squares
Prep time
Cook time

Ingredients:

For the pesto:
  • 2 garlic cloves
  • 20 oz (~1.25 lb) sliced crimini mushrooms, divided
  • 2/3 cup toasted chopped walnuts, divided
  • 1/3 cup extra virgin olive oil
  • 2 tbsp water
  • 1 cup loosely packed fresh parsley
  • 1 tbsp nutritional yeast (optional)
  • 1/2-3/4 tsp kosher salt, to taste
  • Freshly ground black pepper, to taste
For the tart:
  • 7-8 Phyllo Pastry sheets
  • Extra virgin olive oil, for brushing sheets
  • 1 red onion, sliced into long strands
  • Remaining crimini mushrooms
  • Fresh parsley, to garnish

Directions:

  1. Preheat oven to 350°F. Line a large baking sheet with parchment paper. Thaw Phyllo dough according to package directions.
  2. In a large skillet, sauté the sliced red onion in 2 tbsp olive oil over medium-low heat. Stir often for about 30 minutes. In another skillet, sauté the sliced mushrooms in 1-2 tsp olive oil for about 20 minutes or until the water cooks out.
  3. With the food processor running, drop 2 peeled garlic cloves in and process until chopped. Add in 1 cup (saving the rest for the tart) sautéed mushrooms, olive oil, and water and process until smooth, scraping down the sides as necessary. Now add in the rest of the ingredients (using only 1/3 cup walnuts) and process until smooth. Stir in remaining 1/3 cup walnuts. Adjust seasonings to taste.
  4. Place 1 sheet of Phyllo dough onto prepared baking sheet. Brush or spray on oil. Repeat for 7 layers. Carefully fold each side inward to form a crust. With a fork, poke lots of holes all over the phyllo to allow air to escape. You can also weigh it down with pie weights. Bake at 350°F for about 18-20 mins until golden.
  5. After cooling the phyllo for 5 mins, carefully spread on all of the pesto, top with the remaining mushrooms and onion. Garnish with fresh parsley leaves. Cut into squares and serve immediately.

Oh my goodness Angela, I don’t know how you come up such yummy recipes and get me to drool all the time even when I am not hungry. This looks so good, and your photography is superb. Seriously, if you decide to publish a cookbook I will be first in line. Gonna visit Tastespotting. Saw another one of your recipes on an Australian website.

Ohh I never knew they had vitamin D! Now when I eat my omelets with shroomies I know I’m getting a double dose of Vitamin D which is so necessary living in such a northern state.

Katrina September 26, 2011 at 1:30 pm

This sounds lovely!

Audrey September 26, 2011 at 1:37 pm

I don’t think mushrooms have vitamin D unless they are specifically placed in the sun to absorb it. I could be wrong, though.

Oh, and I just have to share my favorite mushroom joke…
Man #1: You know what my favorite vegetable is?
Man #2: No, what?
Man #3: Mushrooms, because I’m such a fun guy.

It’s corny but I think it’s funny. :D

Angela (Oh She Glows) September 26, 2011 at 1:51 pm

lol ;)

Not sure about the Vitamin D thing- that was info I got from the mushroom council.

Reply

marcia shields October 14, 2017 at 5:31 pm

“All mushrooms contain vitamin D, but growers also have the ability to increase D levels by exposing mushrooms to ultraviolet light. Similar to humans, mushrooms naturally produce vitamin D following exposure to sunlight or a sunlamp: mushrooms’ plant sterol – ergosterol – converts to vitamin D when exposed to light.”

Looks so yummy. Love puff pastry tarts, and with pesto, and mushroom pesto at that!! I just went to the competition site and they’ve made a mistake though :( It says ” Canada’s Angela at Oh She Glows shows a Mushroom and Caramelized Onion Tacos” That should be tart not tacos right?

I used to despise mushrooms, but now they’re tolerable. Sometimes the texture gets me, but with vitamin D and these New England winters I should get eating! The pesto looks delectable.

Amanda @ AmandaRunsNY September 26, 2011 at 2:09 pm

I love mushrooms so much I like to roast them and eat them plain with a little balsamic vinegar and salt and pepper. Strange, I know.

This recipe looks awesome. I never would have thought that mushrooms could go in a pesto!

So I tried out this recipe and love it! But I had some troubles with the phyllo dough…all the layers kinda fell apart when I ate it and would you suggest folding the phyllo dough sides? It wasn’t in the original recipe but I noticed you did it in the picture. PS: Would love to talk to you/hear more about your Naturopath experience…I’ve been having some stomach troubles lately and don’t know if a nutritionist or naturopath is the way to go. Okay that was kinda long! Sorry…but thanks for the yummy recipe. :D

I made the mushrooms and the pesto from the recipe in the Oh She Glows cookbook and served on crostini. The mushrooms were good — but the pesto was AMAZING. I think it might be the single most delicious dip/spread type thing I have ever made, with incredible depth of flavor and savoriness. Thank you!

Hi, I wanted to this mushroom tart recipe in the cookbook as it looks wonderful but wondered if I could fully prepare it and then let it sit in fridge for a few hours before heating and eating. Or would that mess up the phyllo?

Thanks!

Do you think I could replace the parsley in the pesto with basil? I have fresh basil at home already and love it, but I wonder if the tastes would work well together..?

Liz November 18, 2016 at 5:48 pm

Hey there! Is this tart ment to be served warm or cold? Im thinking about bringing it to a friends for dinner and prebaking the phylo at home and adding the mushroom pesto a few hours later before serving. Would this work? Thanks!

Reply

Debbie February 15, 2017 at 3:37 pm

I am confused. This is different than the recipe in your cookbook. The book says to cook all the ingredients together for 26-32 minutes. This version says top and serve without cooking the toppings. Which way works best? Thanks!
