Thick and juicy portobello mushrooms are grilled until soft then covered in cheese and a homemade chimichurri sauce.
Any meat lover is sure to love this burger recipe as it is as hearty and satisfying as any other burger recipe out there!
Every once in a while I decide that my family needs to eat more meatless meals. This really has less to do with any social stances or even with the meat itself, it has more to do with the fact that I need to get more veggies into my kids!
Every time I serve up a vegetarian meal like this Honey Garlic Vegetarian Stir Fry, this vegetarian tikka masala, or the vegetarian bolognese, the family goes nuts! So now that grilling season is here, I’m swapping beef for portobello mushrooms!
What Is A Portobello Mushroom Burger?
If you aren’t familiar with a portobello mushroom, they are large, sizeable mushrooms that have a thick and meaty mushroom cap. The cap itself has so much flavor; it is rich and earthy and makes a tremendous substitute for any protein.
These mushroom caps can be grilled just like any other burger and eaten with a bun and traditional burger toppings.
How To Cook A Portobello Mushroom Burger
The mushrooms themselves do not require much. Lightly coat both sides of the mushroom caps with olive oil and salt and pepper. Preheat an outdoor grill to medium-high heat when the grill is ready, place the mushrooms on the hot grates and grill the mushrooms for 2-4 minutes on each side.
The mushrooms do not take long to cook, they will become quite soft in minutes!
If you to cook your portobello mushroom on the stove, place a grill pan or skillet over medium-high heat and cook the mushroom just like you would on the outdoor grill.
How To Cook A Portobello Mushroom Burger In The Oven
The oven is my least favorite cooking method for mushrooms. You just don’t get that smokey flavor, and it takes longer. However, it is just as easy.
Season your mushroom caps as mentioned above. Place the mushrooms on a baking sheet. Roast mushrooms in a 425-degree oven (caps side down) for 18-20 minutes or until tender.
What Goes With A Portobello Mushroom Burger?
The short answer is anything you would put on a traditional burger!
I topped this “burger” with pepper jack cheese and a chimichurri guacamole sauce!
Chimichurri is a green sauce comprised of parsley, cilantro, garlic, vinegar, olive oil, and oregano. It is Argentinian by origin and it tastes amazing with beef, like in this Beef Shish Kebab recipe.
Because I love chimichurri and I love guacamole, I combined the two! Full disclosure, the guacamole in this recipe is simply mashed avocado.
Portobello Burger Toppings:
- Roasted Red Peppers + White Cheddar Cheese
- Caramelized Onions + Gruyere Cheese
- Cucumbers + Feta + Onions +Tzatziki
- Black Beans + Corn,+ Queso Blanco + Green Chilies + Guacamole
- Tomato + Spinach + Red Onion + Goat Cheese Aioli
Grilled portobello mushroom burgers aren’t just for vegetarians. They are lean, flavorful and can be partnered with almost any topping. Give these burgers a try at your next cookout!

The mushroom burgers look incredible!
Thank you Nancy!
This burger looks incredible! I love everything in there…chimichurri happens to be one of my favorite things and I love the idea of mixing it into guacamole. Delicious!
Thank you Marcie! I am smitten with this burger!
Stacy @Stacy Makes Cents says
I have never had a Portabella burger…I’m scared of them. LOL But this recipe makes me want to try one.
Visiting from Jam Hands.
Nothing to fear, I promise!!! They really don’t not have the mushroom flavor you are expecting! They are wonderful!
Loretta | A Finn In The Kitchen says
Sounds like you need to be adjusted ,Tanya! Being married to a chiropractor and almost becoming one myself, I should know 🙂 You can also sleep on your back with a rolled up towel under your neck, but that takes some getting used to…
I love mushrooms, but it’s the one food my hubby doesn’t like, so I could never make such a mushroom-centered meal. Looks delicious to me though!
I seriously need your help then Loretta!!! My poor neck! My husband wasn’t sure about this one, but surprisingly, he loved it!
Lol! I wished I could “like” so many parts of this post…too funny. I also have a crummy pillow and I’ve resorted to using a decorative lumbar pillow in addition to my regular one. It works! These portabellas look insanely good, Tanya!
Ooh, thanks for the tip Cathy!!! I will have a happy neck one of these days!
Yikes! I hope your neck starts feeling better. Nothing worse than a neck ache that is so bad you can’t turn your head. But, I love the chimichurri guacamole idea 🙂
Thank you Nicole!
Your opening photo says it all, Tanya. That is one tasty looking burger — and healthy, too. It’s not often you can use burger and healthy in the same sentence. 🙂
You are right John, burgers are not synonymous with healthy! Too bad huh?
Rachel (@rachelcooksblog) says
Yes please! Love the idea of that gauc!
Guac was the best part!
Krista @ joyfulhealthyeats says
Awesome recipe. I love portabella burgers! The idea of a chimichurri guacamole in top is genius! Can’t wait to try this, definitely pinning. 🙂
Thank you Krista! The guacamole is soooo good! Good enough to eat on its own!
Gloria Phillips (@simplygloria1) says
You crack me up Tanya! I hear you about the pillow thing…the search for a perfect pillow is very time consuming. Most don’t understand.
This is a great recipe! My hubs would love this. (=
Thank you for understanding Gloria! And my burger loving husband absolutely loved this vegetarian version!
Heather @ Sugar Dish Me says
I have all these herbs on my porch! Score!!
So sorry your pillow is a pain in the neck– nothing is worse than a crummy night’s sleep. Hope you find a new AWESOME pillow.
How lucky to have cilantro and parsley on your porch! You will love these!
Eco Friendly Homemaking says
Okay now this just looks awesome!
Well thank you!
Diane (@SimpleLivingEat) says
Great idea with the salsa..love the healthy burger.
It was a great change from the norm!
Mmmmmmmmmm…………I just LOVE bella burgers but with the addition of the special guac, I know it was just fantastic!
I thought it was fantastic, but I am certainly biased!
BruCrew Life says
I hope you find a good pillow soon!! It’s hard to do much in a day with a nasty kink in your neck! These burgers look/sound fantastic!!! Yum!!
Thank you Jocelyn!
Neck kinks are the worst! One of the many reasons I love my Chiropractor! This is a beautiful burger I can’t wait to try it
I might need a chiropractor! I loved this burger!
Heather @ French Press says
I am in LOVE with this burger
Thanks Heather! I’m smitten too!
Daniel @ TickleMyTastebuds says
Oh my, nothing quite like avocado, mushrooms and a nice, thick burger to kiss those angries away – mouthwatering!
I agree Daniel!
Tanya, I love all the flavor you packed into this portabella burger especially the chimmichurri. It will be a Thursdays Treasure Feature.
Thank you Christie!
Woot! You have been featured this week at Recipe Sharing Monday! The new link party is up and I’d love to see you back. Have a great week. 🙂
Yeah! Thank you Ali!
Sandee wheeler says
You should try a Tempurpedic pillow! I LOVE mine!
I have to look into that Sandee! Thank you.
Made these tonight and they were delicious!! They will definitely be making an appearance on our table again very soon! One quick question: is the 2 Tbsp olive oil for the chimichurri and the 1/2 c for drizzling on the mushrooms? That’s how I did it tonight but just wanted to clarify. Thanks!
I am so happy to hear this! Those burgers are my all time favorite!
I love this! It takes just like a burger on the grill but the guacamole is a great addition!
Chris Collins says
I love a good mushroom burger, never thought of pairing it with chimichurri guac but I’m totally gonna start now!!
I love guacamole on my burgers…I won’t eat them any other way!
Okay, just the name of this dish is making my mouth water!!!! Looks soooooooooo good! That guac is out of this world too!
Anita @ Daily Cooking Quest says
First time I’m seeing a whole cap of portabella in a burger! But I’m super excited to give this a try. I bet the burgers taste really good with the chimichurri and guacamole.
Ok, I think I could maybe eat anything with that guacamole on it!! Sounds amazing!! Thanks!
Sara Welch says
I know what I will be having for dinner tonight! What a savory and flavorful recipe!
Jacque Hooper says
Wow! This looks amazing; a restaurant worthy dish, indeed!

This sounds so good! Love the addition of the guacamole!

This looks really wonderful. I do think spaghetti squash is a great option for enjoying traditional noodle dishes on a grain-free diet. Thanks for posting this on Food Flicks Friday.
