Portobello mushrooms are the closest thing in the vegetable world to a steak. They are meaty, substantial, and take on grill flavor beautifully. A simple balsamic marinade is all they need — the acid tenderizes the surface while the garlic and herbs add depth.
The key is not to overcook them. You want them tender and juicy, not dry and leathery. A few minutes per side over medium-high heat is all it takes. The grill marks add flavor and visual appeal, and a final drizzle of balsamic glaze ties everything together.
Ingredients
- 4 large portobello mushroom caps, stems and gills removed
- 3 tbsp balsamic vinegar
- 3 tbsp olive oil
- 3 cloves garlic, minced
- 1 tbsp soy sauce or tamari
- 1 tsp dried Italian seasoning
- 1/2 tsp salt
- 1/4 tsp black pepper
- Balsamic glaze for drizzling
- Fresh basil or parsley for garnish
Instructions
- 1
Gently clean the mushroom caps with a damp paper towel. Remove the stems and scrape out the gills with a spoon if desired.
- 2
Whisk together the balsamic vinegar, olive oil, garlic, soy sauce, Italian seasoning, salt, and pepper.
- 3
Place the mushrooms gill-side up in a dish and pour the marinade over them. Let sit for 15 to 20 minutes.
- 4
Preheat the grill to medium-high heat and oil the grates.
- 5
Place mushrooms gill-side up on the grill. Cook for 4 to 5 minutes until grill marks form.
- 6
Flip and grill for another 3 to 4 minutes until tender and slightly charred.
- 7
Remove from the grill and drizzle with balsamic glaze. Garnish with fresh basil or parsley.

Soy Sauce
Helpful Pantry Staple
Why the soy sauce matters
This is doing more than adding salt. The right soy sauce gives the recipe a rounder, more savory base than a thin generic bottle.
This pantry choice affects depth more than most seasonings here.
- Builds savory backbone quickly
- Useful across stir-fries, marinades, and dipping sauces
A better soy sauce is one of the easiest pantry upgrades for Asian cooking.

Pro Tips
Do not press the mushrooms while grilling. Let them cook undisturbed for the best grill marks.
Removing the gills is optional but prevents a dark, inky liquid from pooling.
These work great as a burger substitute on a bun with all the fixings.
Storage
Refrigerate in a sealed container for up to 3 days.
Reheating
Reheat on the grill for 2 minutes per side, or in a skillet over medium heat.
