The Best Grilled Portobello Mushroom Burgers



I set out to make a great tasting grilled portobello mushroom burger that even a meat lover would love. The mushrooms are marinated then grilled and topped with melted Swiss Cheese, grilled red onion,  tomatoes, spinach, and avocado – yum!!

The only thing my husband said would make these burgers better is adding bacon... maybe next time.
I wanted to give the mushrooms a meaty flavor, so I marinated them with balsamic, soy sauce and Montreal steak seasoning. These were so good, perfect for meatless Mondays or any night of the week.

Servings: 4  • Size: 1 loaded burger  • Old Points: 6 • Weight Watcher Points+: 8 pt
Calories: 295 • Fat: 13 g • Carb: 31 g • Fiber: 11 g • Protein: 21 g • Sugar: 6 g
Sodium: 594 mg (without salt) • Cholest: 0 mg

Ingredients:

  • 4 portobello mushroom caps
  • 2 tbsp balsamic vinegar
  • 1 tbsp low sodium soy sauce
  • 1 tablespoons olive oil
  • 1 tbsp chopped rosemary
  • 1-1/2 tsp steak seasoning like Montreal Steak Grill Mates
  • 4 thick slices red onion
  • 4 oz reduced fat Swiss, sliced thin (Alpine lace)
  • 4 thin slices tomato
  • 1/2 avocado, sliced thin
  • baby spinach
  • 4 whole wheat low calorie buns (I used Martin)

Directions:

In a large bowl, whisk together vinegar, soy sauce, oil, rosemary, and Montreal steak seasoning. Place the mushroom caps in the bowl and toss with sauce, using a spoon to evenly coat. Let stand at room temperature for 20 to 30 minutes, turning a few times.


Heat the grill or indoor grill pan over medium heat. When hot, brush the grate with oil or lightly spray the grill pan. Place the mushrooms on the grill, reserving marinade for basting. Grill for 5 to 7 minutes on each side, or until tender, brushing with marinade frequently.


Top the mushrooms with cheese during the last minute of cooking. While the mushrooms cook, grill the onions about 1 minute on each side and grill the buns until toasted.

To finish, place the spinach and grilled portobello mushrooms on the buns and top with the grilled onions, sliced tomato and avocado.

  11. Do you clean out the gills on the underside, or leave them? If you clean them out, do you have tips? I always end up mangling the mushroom...

    1. I scrape mine out with a small spoon. I actually used to use a grapefruit spoon (has a kinda serrated edge) but husband mangled it in the garbage disposal. :( I like the texture better without the gills.

  24. These were fantastic! I followed your recipe and they were absolutely delicious. My husband was surprised by how full he was after eating it. Thank you for the wonderful recipe.

  26. THRILLED you all enjoyed it!!!!

  27. I honestly have NEVER liked portobello mushrooms, but I liked all the other ingredients and became intrigued by how you flavored them so I thought I'd try it. OMG best burger I've EVER had, I did throw in a slice of turkey bacon just in case, but it didn't "need" it. I'm so excited by this recipe, because I love burgers, but try to stay away from the red meat. Just thought I'd let you know how much I appreciate it, thank you!!

    1. Michelle, I found your review incredibly helpful because I find I am indecisive about mushrooms. I've always wanted to try portobello burgers but have been too scared to try them and yet I find myself time and time again looking at recipes of them. Because of your review, I will be trying them tonight!

  28. These were AMAZING! Never even got a chance to make a burger out of them. I think I ate three of the over the course of an evening. So good. Definitely a keeper!!

  30. Blog is best from reader/customer/client point of view. Its a clear , fast and good approach to make everything simple. I found some info on Free Likes and Tech Blog but still i need some reference.

  31. Making these right now, as a yummy surprise for my husband, there his favorite. blueberryoatmealcinnamon@blogspot.co.il

  32. I made this for my dinner tonight -- O.M.G. it was the juiciest & most delish portabello burger!! I used to make a Weight Watcher recipe for one, but this was much better. I didn't have the Montreal steak seasoning so I just seasoned the marinade with garlic, pepper, onion powder. I also made a quick little sauce using fat free mayo mixed with dijon mustard, fresh ground flower pepper, garlic, and rosemary (it's just like the sauce they use at Five Napkin Burger in NYC, but mine was fat free!)).....total WOW factor for this "burger!!!!

  33. These look amazing, def plan on trying them. Do you know what the calorie count is without the bun? Thx!

    ReplyDelete
  34. This was awesome!!!! We made it tonight and my carnivore husband actually really liked them and said we should make again! Thank you :)

    ReplyDelete
  35. Making this second week in a row. My husband LOVES portabella's me not so much. Though I tried this to make him happy and I must say I enjoyed it myself much more than I thought.

    Thank you for making me go out of my comfort zone.

    I love your website, and recipes!! Keep up the great work :)

  36. Had it twice now (sans the avocado and tomato), and i still cannot believe how awesome this is.... the marinade for the portobello is awesome, and the cheddar, grilled onion and teh bun definitely make you believe this is a burger...just a juicier burger than I'm used to, so I'll probably prefer this one to a meat patty in the future (the funny thing is that I'm not a vegetarian, but I already discovered that lentils are better than ground beef in a sloppy joe, so this didn't come as a complete surprise!)

    ReplyDelete
  37. I made these tonight and loved the recipe! Even my husband, who hates mushrooms, took a bite and said "I could eat a whole one!" (He ate a salmon burger instead.) Thanks for the great recipe... we'll be making this again!

  38. Are portabello mushrooms 0 points? These look delicious. I was just searching for recipes using portabellos and came across this.

    ReplyDelete
  39. May I ask which kind of indoor grill pan you use? I see that you did not use one in the pictures above for this recipe, but I've seen you post pics where you use one with different recipes. I don't have one yet, but I think that it would be nice to have as a Chicagoan once the weather starts to cool down.

    Thanks!

  40. So delicious! Broiled them rather than grilling because I could only find sliced portobellos. I didn't want them to fall through the grill! 5 minutes on each side, applying marinade at the flip. Just used a generic steak seasoning. Very, very good - will be making again!

  42. Can i use a toaster oven instead of a grill?

    ReplyDelete
  43. I made these last night and they were delicious! It was my first ever portobello burger. I did, however, find them VERY juicy (to the point that they were difficult to eat as a burger). Just wondering if I did something wrong or if that is typical of a portobello burger?

    ReplyDelete
  44. I made this today and they came out amazing. I don't like really juicy food , so what I did was poke the cap with a fork several times. This helped release any excess juice without leaving it dry. Will defiantly make again!

    ReplyDelete
  45. Gina-If you dont have a grill is it impossible to do???? any ideas-also what if you marinated over night would that be bad?

    ReplyDelete
  46. These are FANTASTIC - definitely a keeper! I never would have guessed a mushroom could be sooooooooo juicy. We have vegetarian friends arriving today for a visit and we're grilling these up tonight for dinner :)

    ReplyDelete
  47. What makes the fat content so high? If its the avocado, what would be the calories and fat without it?

    ReplyDelete
  48. Amazing! Made these tonight on our grill pan and my husband had 2 he isn't a mushroom fan even -will definitely make these again! I didn't have rosemary but used French thyme instead and came out delicious!

    ReplyDelete
  49. this was yummy! I sautéd the onions and layered with avocado and tomato. No bun but made some potstickers and it went well. Over spinach

    ReplyDelete
  50. I imagine this would be a great vegan burger, but I made the mushrooms to go on top of steak...it was outstanding and very delicious. I usually don't like balsamic vinegar but this recipe was quite good

    ReplyDelete
  51. Just had this tonight. Delicious!! I'm a vegetarian, but my husband is not and he loved it as well!

    ReplyDelete
  52. Loved it! And my skeptical fiance did as well : )

    ReplyDelete
  53. Easy and delicious!

    If asked for a suggestion, try just 1/2 tsp of Montreal Steak Grill Mates for a milder after-taste.

    ReplyDelete
  54. I made these today for dinner. I removed the gills, used a fry pan - no grill, and fried the onions till brown. The marinade was perfect, and so was the burger. I always had trouble finding a marinade I liked. This is a winner.

    ReplyDelete
  55. That looks delicious! like this http://best-foood.blogspot.com/2014/02/easy-healthy-burger.html

  56. I just made these and they were incredible!!! Thank you for the recipe!

    ReplyDelete
  57. These definitely are the best. I've made some cheese stuffed ones but they are so heavy compared to these. Thanks for sharing.

    ReplyDelete
  58. Seriously Excellent....added one finely minced garlic clove....used Braggs Amino for soy sauce and only 1/2 teaspoon Montreal Seasoning to cut back on salt.....grilled both sides......definitely our new favorite.

    ReplyDelete
  59. How do I cook them without a grill?

    ReplyDelete
  60. I have made these several times and they are excellent. My meat loving husband said he did not miss the meat! Thanks Gina I'm not on WW but diabetic and have made several of your recipes to eat healthier and have loved everything I've tried...can't wait for your cookbook!

    ReplyDelete
  61. This was delicious! I added a twist. Instead of cheese I used Nutritional Yeast flakes. They melt like a cheese and taste pretty close with almost no fat, 0 cholesterol but 9 grams of protein for a 3TB serving! I did everything else exactly per the recipe. Yummy. thanks! JM :)
