Grilled Portobello Mushrooms
Ingredients
- 4 portobello mushroom caps
- ¼ cup balsamic vinegar
- 2 tbsp extra virgin olive oil
- 1 tbsp Italian spice
- salt and pepper to taste
- parsley & balsamic reduction to garnish (optional)
Instructions
- Gently wash the mushroom caps, remove the stems and gills. Poke holes into the bottom side of the mushroom with a fork to allow the marinade to soak in. Be careful not to put the fork through the mushroom.
- In a medium mixing bowl, add balsamic, olive oil, Italian spice, salt and pepper and whisk well to combine.
- Add the marinade to the mushrooms, cover, and allow to marinate for 10-15 minutes.
- Preheat the grill to medium/high heat, and place the portobellos on the grill for about 4-5 minutes per side. When the mushrooms are almost ready, brush on 1/2 of the remaining marinade.
- Remove from the grill, brush on the rest of the marinade, garnish with your favourite toppings and enjoy!


Okay so I tried to grill these this weekend and they turned out perfect for my vegan BBQ guests! They do shrink down quite a bit so I made 8 and my guests loved them. I also used a vey nice high quality balsamic vinegar and I do think that’s very important!
