These mushroom burgers are super easy to prep and have lots of savory flavor with a garlicky marinade. Top them with a slice of melty cheese and your fave toppings for a new favorite. These tasty burgers deliver so much bold and savory flavor—you don’t have to be vegetarian to enjoy them!
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.
How to Make Portobello Mushroom Burgers
Grilled portobello mushrooms make any meatless meal ah-mazing! Serve with buns and toppings as desired.
Mushroom Burger Toppings
Think outside of the bun and experiment with different toppings for portobello mushroom burgers.
Try red onions, thick slices of tomato, lettuce, arugula, or sliced cucumber. Replace the usual burger condiments with basil pesto mixed with mayonnaise, tzatziki, or honey mustard.
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. Did you enjoy this Portobello Mushroom Burgers Recipe?
