While portobello mushrooms are ideal for this recipe, you can use large shiitake or king oyster mushrooms as a substitute, but cooking times may vary.
You can substitute olive oil with avocado oil or a neutral oil like canola or grapeseed oil, maintaining the same quantity for the marinade.
To adjust spice levels, reduce the amount of red pepper flakes in the chimichurri sauce or omit them altogether. You can also add more lemon juice to balance the flavor.
- Make sure to clean the portobello mushrooms thoroughly by gently wiping them with a damp cloth or paper towel to remove any dirt.
- Marinate the mushrooms for at least 30 minutes before grilling to allow the flavors to fully infuse.
- Use a grill pan or outdoor grill to cook the mushrooms for an added smoky flavor.
- Grill the mushrooms on medium-high heat to ensure they cook evenly and develop a nice char.
- For the chimichurri sauce, make sure to finely chop the parsley, garlic, and shallot; this helps to evenly distribute the flavors.
- Use a ripe avocado for a smoother and creamier chimichurri sauce.
- Prepare the avocado chimichurri sauce just before serving to maintain its vibrant color and fresh taste.
