Take your mushroom game to the next level with these amazing grilled portobello mushrooms! Flavored with a tasty marinade of balsamic vinegar, Worcestershire, lemon juice, garlic, brown sugar, and more.
Deliciously Marinated Mushrooms
Portobello mushrooms are such a versatile and fun vegetable to cook with. These little wonders make for a fantastic complement to proteins and can enhance the flavors of various pasta, casseroles, stir-fries, and more. Yet, their most recent notable attribute is their ability to serve as an exceptional substitute for meat!
Like meat, mushrooms can take in the flavors around them and become tender when cooked correctly. They have a deep, umami taste and a meaty texture that makes them a great option to replace ground beef, pork, or chicken in prepared dishes.
This brings us to the true star of this grilled portobello mushrooms recipe: the delicious balsamic marinade. It creates the most flavorful and tender mushrooms. Once grilled, they get that smoky charcoal flavor that is simply divine. And get this, all you need are simple ingredients you already have at home.

Dredge the mushrooms in the marinade a few times to coat them. Then let the mushrooms marinate for 1 hour, flipping them halfway through.

When the grill is heated, grill the mushrooms for 10 minutes, flipping halfway.
Then, transfer the mushrooms cap side down on the grill over indirect heat. Grill the mushrooms for 3 minutes on the cap side, flip, and grill them for an additional 2 minutes.

Top Tips for Grilled Portobello Mushrooms
How to Pick the Right Mushrooms
Since you’ll be grilling these mushrooms, it’s important that you get mushrooms that are bigger in size to prevent them from falling through the grates. However, you won’t need to worry about that if you’re using a grill pan.
You’ll also want to use large portobello mushrooms if you’re using them as hamburger patties, ideally around the same size as the bun. Look for mushrooms with caps that are firm and have no visible cuts or bruises.
How to Clean Mushrooms
Cleaning mushrooms isn’t complicated, but it’s a crucial step when you’re cooking. You don’t want to be eating any dirt! Here’s the scoop on getting ‘shrooms squeaky clean.
First, place them in a colander and rinse under cold water for 30 seconds. Get rid of any dirt that’s stuck in the crevices. Then use a damp paper towel to rub off any remaining dirt. Finally, get a dry paper towel to pat them so they are ready for use.
Seasoning & Grilling
Portobello mushrooms already have a rich, meaty flavor that doesn’t need too much enhancement. Keeping it simple with some sea salt, black pepper, and a light brush of olive oil is all you need to make the most out of grilled portobello, but of course, you can really elevate them by soaking them in a marinade like this one!
You don’t need a fancy outdoor grill to make these mushrooms either, you can cook them on a gas grill, electric grill, or grill pan just as easily.
