How do you clean portobello mushrooms before grilling?

To properly clean portobello mushrooms for grilling, first gently wipe the caps with a damp paper towel to remove any dirt or debris. Avoid soaking them in water, as mushrooms act like sponges and will become soggy. Next, carefully slice off the woody stems, and if desired, use a small spoon to lightly scrape out the dark gills from the underside.

How long does it take to grill portobello mushrooms?

When cooking on a preheated grill over medium-high heat (around 450°F), portobello mushrooms take about 10 to 14 minutes total. You should grill them for 5 to 7 minutes on each side. You will know they are perfectly done when they are tender, slightly shrunken, and have beautiful, dark grill marks.

Do I have to remove the gills from portobello mushrooms?

No, removing the gills from portobello mushrooms is completely optional! The gills are 100% edible and actually hold a lot of rich, earthy flavor. However, some people prefer to scoop them out because they can release a dark liquid during cooking that might muddy the presentation of your dish.

What are the best toppings for grilled portobello mushrooms?

Grilled portobellos are incredibly versatile! For a rich, savory side dish, try topping them with melted mozzarella or parmesan cheese, crispy bacon crumbles, or a drizzle of sweet balsamic glaze. If you are serving them as a vegetarian burger, load them up with fresh lettuce, juicy tomato slices, red onion, and creamy guacamole.

Ingredients

4 large portobello mushroom caps, cleaned and stems removed
3 tbsp olive oil
1 tbsp unsalted butter, melted
2 tbsp balsamic vinegar
1 tsp fresh thyme leaves
1/2 tsp garlic powder
1/2 tsp kosher salt
1/4 tsp black pepper

Instructions

Prep the Grill: Preheat your outdoor gas or charcoal grill to medium-high heat (about 450°F). Ensure the grates are clean and lightly oiled.
Clean Mushrooms: Gently wipe the tops of the mushrooms with a damp paper towel. Remove the stems and optionally scrape out the dark gills with a small spoon.
Make Marinade: In a small bowl, whisk together the olive oil, melted butter, balsamic vinegar, fresh thyme, garlic powder, salt, and pepper.
