A good grilled portobello mushroom burger is one of my favorite summer meals. Cooked well, it has a tangy, savory charred flavor and meaty texture that’s absolutely delicious inside a toasted bun. I love a good homemade veggie burger, but when I’m craving something meaty and I’m not in the mood to get out the food processor, a grilled portobello mushroom is my #1 choice. These come together in about 20 minutes and the mushrooms require just 5 simple ingredients.
How to Make Grilled Portobello Mushrooms
If you’ve never grilled portobello mushrooms before, you’ll be surprised by how easy it is. Just follow these simple steps:
- Remove the stems from the mushrooms and use a damp towel to wipe the caps clean.
- Drizzle them generously with olive oil, balsamic & tamari and sprinkle them with salt & pepper. Use your hands to make sure they’re fully coated – it’ll be a little messy, but the better coated your burgers are, the more flavorful they will be!
- Preheat your grill or grill pan and put on the mushrooms, starting with the gill side up. Grill for 4-5 minutes per side, until the mushrooms are tender and grill marks form.
- Top with your favorite fixings, and enjoy!
Portobello Mushroom Burger Serving Suggestions
In my first cookbook, I top my portobello mushrooms with a bright green cilantro pepita pesto. I love eating them this way, but if you’re a portobello mushroom burger traditionalist, there’s no need to worry. The grilled portobellos are just as good with classic fixings like ketchup, mustard, mayo, pickles, and onion. Of course, I wouldn’t say no to a scoop of guacamole and/or a dollop of chipotle sauce.
If you’re serving these for a picnic, corn on the cob, potato salad, pasta salad, broccoli salad, or orzo salad would all be excellent on the side.
