Grilled Portobello Mushrooms with Balsamic

July 24, 2025

Grilled Portobello Mushrooms with Balsamic are a simple yet sophisticated dish that brings out the natural umami flavor of these meaty mushrooms while adding a rich tang from the balsamic vinegar. Perfect as a main or a side, this dish is ideal for vegetarians or anyone looking for a lighter alternative to meat, but with all the flavor and depth.

Portobello mushrooms are perfect for grilling because of their dense, meaty texture, which holds up well over the heat. When grilled, they become smoky and tender with a slightly crispy exterior. The addition of balsamic vinegar elevates the mushrooms, giving them a sweet yet savory glaze that caramelizes beautifully on the grill, infusing each bite with a rich, tangy flavor.

To prepare, start by removing the stems from the mushrooms and brushing both sides with olive oil, salt, and pepper. This helps them cook evenly and ensures that they stay moist while grilling. A quick marinade with balsamic vinegar, garlic, and a touch of honey or brown sugar brings out the sweetness in the vinegar and helps create that perfectly caramelized finish. After marinating for just 15-30 minutes, the mushrooms are ready to be grilled.

Grill the mushrooms for about 5-7 minutes on each side, brushing them with the balsamic glaze as they cook. The result is a savory-sweet, smoky mushroom that can be served as a standalone dish, or paired with pasta, quinoa, or a fresh salad.

To add an extra layer of flavor, top the grilled mushrooms with fresh herbs like thyme or rosemary, and perhaps a sprinkle of parmesan cheese for a bit of richness. The combination of the earthy mushrooms, tangy balsamic, and aromatic herbs makes for a dish that’s simple to prepare yet bursting with flavor.

Grilled Portobello Mushrooms with Balsamic are a deliciously satisfying dish that feels indulgent without being heavy. Whether you’re cooking for yourself or entertaining guests, these mushrooms will definitely impress with their rich flavor and smoky char.

    I tried this recipe and it was just okay. I think I expected more flavor from the balsamic but it was kinda bland. Maybe I’ll try adding more garlic next time.

    So easy but do we have to grill? Can I just bake them instead? Also, is it thyme or time? 🤔

    Is 15 minutes of marinating really enough? I left mine for an hour and they turned out great!
