How To Make Grilled Marinated Mushrooms: Step-By-Step
Step 1: Clean and dry the mushroom caps.
Step 2: Prepare the marinade by combining the olive oil, vinegar, garlic, chopped rosemary, and salt.
Step 3: Marinate the mushrooms for a minimum of 30 minutes.
Step 4: Grill over medium heat until the caps are tender.
Hint: Use balsamic vinegar in this recipe. Other kinds of vinegar will not give the same flavor that a good quality balsamic will have for grilled veggies. I am picky about my olive oil and vinegar. This is the brand that I use.
Top tip
If you can find them, use fresh herbs. Using fresh rosemary will make the marinade delicious as does freshly chopped garlic.
How to Clean Portobello Mushrooms
You will definitely want to clean your mushrooms before making this recipe:
- Remove the stems and discard or save them for soup or other uses.
- With a paper towel, gently rub off any dirt from the caps.
- While I don't do this, it helps by keeping the caps from "leaking" juice - using a small spoon, gently scrape the underside of the mushroom caps to remove the gills. The gills are edible however.
How To Store These Grilled Marinated Portobello Mushrooms
Store in an airtight container in the refrigerator. When you are ready to eat them, reheat in a skillet over medium heat or microwave in 30-second intervals. Cooked portobello mushrooms will last in the refrigerator for up to three days.
Frequently Asked Questions

No. You can simply pour the marinade over them and then grill. However, I have found that 30 minutes of letting them sit and develop the flavor.
Yes. While portobellos are the easiest to grill, large-cap shitake mushrooms will also work. If you decide to marinate and then saute on the stovetop, you can use any type of mushroom for this recipe.
