What You’ll Need For Portobello Burgers
Mushrooms: I like to choose the largest portobello I can find since the mushrooms shrink in size as they cook. If they’re small, you might like to double up in each bun.
Marinade: Worcestershire sauce, soy sauce, and minced garlic cloves add savory flavor to portobello mushrooms. Experiment with your favorite burger seasoning. If you are preparing these for vegan or vegetarian guests, note that Worcestershire sauce is not vegan.
Cheese: I love Havarti cheese on these burgers, but almost anything goes! Try mozzarella, cheddar, or smoked gouda.
Buns: Like regular beef burgers, grilled portobellos are juicy, so choose sturdy hamburger buns, brioche buns, or ciabatta bread.
I love the flavor toasting the buns adds. Brush the buns with olive oil or spread garlic butter on them and toast them on the grill until golden.

Holly’s Pro Tips
- If possible, wipe the mushrooms with a damp paper towel instead of rinsing them. If they’re very dirty, they can be quickly rinsed but make sure they don’t absorb water.
- The marinade adds lots of flavor to this burger recipe so allow marinating time.
- I recommend removing the gills on the underside of the mushroom as they can trap bits of debris.
Got Leftovers?
Store leftover grilled portobello mushrooms in a covered container in the refrigerator for up to 4 days.
Reheat them in the oven with fresh slices of cheese and make more burgers or slice them up and top a salad or add to a stir fry.

Wipe the mushrooms clean with a damp paper towel and remove and discard the stems. Use a spoon to gently scrape out the gills.
In a large bowl whisk olive oil, soy sauce, Worcestershire sauce, garlic, and salt & pepper to taste. Add the mushrooms and toss well to coat. Let marinate at least 15 minutes.
Preheat the grill to medium-high heat.
Place the mushrooms, gill side down on the grill, and cook for 5 to 7 minutes. Flip the mushrooms over and cook for an additional 4 to 5 minutes or until tender. Add the cheese on top and cook a minute more or until melted.
Place the mushrooms in the buns and add toppings as desired.
*If your portobello mushrooms are small, use 8 mushrooms and double them up on your burger.
