Skip the packaged veggie dogs at your next cookout - grill these tangy marinated portobello mushrooms instead! They're easy, healthy & flavorful.
We’re all familiar with the ubiquitous portobello burger, so I’ll be honest: I originally planned to serve these mushrooms in hot dog buns for the novelty of it. For my money, though, portobellos really work better in dog form than in burger-form. They get more fully covered in the tangy, savory marinade, and (because they’re thinner strips) they cook a lot more quickly and more evenly.
Portobello Veggie Dog Recipe Ingredients
Growing up around Chicago, hot dogs were never taken lightly. A good Chicago dog has a myriad of components, including mustard, onions, a whole pickle, peppers, and more. This recipe is by no means one for a classic Chicago dog, but, using it as inspiration, I made sure my components included something tangy, something fresh, something meaty, something spicy, and something bright:
- Portobello mushroom strips take the place of meat, adding their umami flavor & meaty texture. A simple 5-ingredient marinade of balsamic, mustard, salt, pepper & olive oil makes them extra rich & tangy.
- Tomatoes and red onion form a fresh slaw that I season with lime, salt & pepper. It adds crunch and brightness to the dogs.
- Serrano pepper slices kick up the heat.
- And a drizzle of mustard gives everything a tangy finish.
How to Make Grilled Portobello Mushroom Hot Dogs
This healthy veggie dog recipe is SO easy to make! Just follow these simple steps:
- Use a damp kitchen towel to wipe your portobello mushroom caps clean and then twist off the thick stems. Save the stems for stock or compost them.
- Slice the caps into 4 long slices – you’ll use two per dog.
- Mix together the balsamic/mustard marinade, and brush it onto the mushroom strips until they’re well-coated. More marinade = more flavorful dogs.
- Preheat a grill or grill pan to medium high, and grill the mushrooms until grill marks form and they’re tender and juicy, 3-4 minutes per side. Remove from the heat!
- Stuff two mushroom strips into each hot dog bun, and load your veggie dogs up with slaw, sliced serranos, and mustard. Dig in!
Portobello Mushroom Dog Serving Suggestions
I love to serve my mushroom dogs with a healthier pasta salad, like this one with broccoli or this one with with tons of summer veggies. Couscous salad, strawberry salad, summer slaw, or watermelon salad would also be great on the side.
Complete the meal with my favorite crispy baked sweet potato fries and chipotle sauce for dipping!

Add the chopped scallions, bell pepper, cherry tomatoes, peas, capers and sliced basil. When your macaroni noodles are cooked, drain them well, then transfer them into the large bowl. Toss to mix the noodles with the veggies and the dressing. Taste and adjust seasonings, chill until ready to serve. If you want a creamy salad, add a big scoop of greek yogurt once your salad is somewhat chilled.

Great recipe. Thank you for your sharing.
So glad you enjoyed it!

Great recipe. I’ve made portobello burgers before and using them for “hotdogs” is a great idea. They are “meaty” and the marinade works well. I double the marinade. I also top with celery salt.
I’m frequently disappointed by vegan recipes but this was a welcome suprise. Thanks!
I love that stencil too! I’ve been trying to win it on EVERY cutting edge stencil giveaway I see.
I love this idea! I always make portabello “burgers” but I love the idea of slicing them lengthwise and making them hot dogs. Adorable, fun and so delicious. Thanks for the great idea.
These will be perfect for the upcoming holiday weekend! And am I missing something? I can’t find the macaroni salad recipe anywhere!
Hi Kristen, it’s back now – under the mushroom dog recipe!
Not only do these pups look amazing…. they are very filling and hearty! I featured this recipe in my recent post “30 Portobello Mushroom Recipes in 30 Minutes or Less”! http://vegan.supply/30-portobello-mushroom-recipes-in-30-mins-or-less/ Thanks!
Thank you for the recipe.. 🙂
Great little recipe. Top marks. Thanks for sharing this.
This Portobello Pups recipe was delicious! I put four slices of the mushrooms on each bun, and I substituted a deli bun (more like a sausage bun) instead of a hot dog bun. I also put a handful of arugula on each bun. I will definitely make this again. Thank you!
Unfortunately I don’t have a grill because they’re not allowed on condo balconies. Would it work if I used an electric grill, Jeanine?
Also is there a benefit to cooking them in strips rather than whole and slicing after they’re done?
Hi Michael, I’ve never used an electric grill, but I’ve made these on a cast iron grill pan over the stove. I like the strips because more of the marinade gets absorbed, also, they cook faster than whole ones!
Great idea! I happen to have a cast iron grill pan so the mushrooms will have grill marks to complete the aesthetic.
Thank you again.
I so love these two ideas. These ‘pups’ (great name!) look delightful and so much yummier than traditional hot dogs, whatever it is that they’re made of anyway.
I love this, and will be making them! BUT, you are under-utilizing the grill! If you want a milder red onion taste, brush the slices with olive oil and throw them on the fire. Some grilled zucchini and/or asparagus can get chopped to go in the pasta salad, maybe with cubed grilled haloumi as well.
