Summer herbs are a treasure trove of flavor, and the bright floral notes of tarragon shine through in this crowd-pleasing burger recipe. Smoky grilled portobellos are layered with fresh spinach, tomato, and a creamy cashew-based tarragon sauce for a meal that will please kids and adults alike. Pair these savory burgers with a handful of Baked French Fries to satisfy all your fast food cravings without the unhealthy ingredients.

Ingredients

  • ⅓ cup raw cashews, soaked in very hot water for 15 minutes
  • 1 tablespoon tahini

Can you fry the mushrooms in a pan also … it looks really good I love Portabella mushrooms

Courtney Davison

Hi Debra, If you're making it on the stovetop, it would be best to use a grill pan, since we don't recommend using oil. You could try using a skillet, adding a tablespoon or two of water as necessary to prevent sticking—but the beauty of a grill pan is that you'll get the nice grill marks and you won't have as much of the mushroom directly touching the pan, so you'll have less sticking, too. If you try it, please let us know how it goes. Thank you! Warmly, Courtney Davison Editor, Forks Over Knives

Very delicious ~ the sauce is spectacular, and all the ingredients come together nicely. Easy to make. Reminded me of foodie restaurant-quality. The only problem I had is that the ingredients slip around and eventually become a knife and fork dish. Otherwise, highly recommend.

Lori

Do these freeze well?

Gretchen

These are SO good! I made these 3 times in 2 weeks. You don’t see enough recipes with tarragon so that was nice. I ate them without a bun and they were perfect.

Elizabeth

Outstanding! I used 2 tsp dried tarragon in place of fresh.

Janet

Wow. That was so good. I added slice onion and avocado. I used basil and fennel because I didn’t have tarragon. Yum!

Gretchen Melton

These are so good I made more the next night. Ate them without a bun and they were delicious!

Val F

Made this for dinner today. It was Fantastic!

Sharon

Can you do the mushroom in a skillet or in the oven?

Sandy

Yes, you could. I’ve done this with teriyaki soaked portobello.

Joann

do you clean gills out of mushrooms?

Marcia Carson-Smith

Wonderful recipe

Diana Workman

Made this last night for dinner and the tarragon sauce was heavenly!! Complimented the portobello and tomato perfectly! I put the mushroom top on half of Dave's Bread multi grain bun and cut with knife & fork. Seems impossible to grill the mushroom tops for 15 mins but it was needed (on medium heat). Nice, tasty recipe!

ADHD Coach

Delicious. My non-vegan spouse loved it, too.

Chris Kepler

This recipe is amazing. You will not be disappointed.

Anna Virginillo

Delicious!
