Grilled Portobello Mushrooms Recipe

Back when I first started cutting back on heavy meats, I was desperate for something that still felt satisfying on the grill. That’s when I stumbled on portobello mushrooms. I’ll never forget the first time I marinated and grilled them—they were juicy, rich, and totally crave-worthy. Even my meat-loving husband said, “Wait…this is a mushroom?!” Now, they’re our go-to when we want something hearty but light.
Ingredients
-
4 large portobello mushroom caps, stems removed and cleaned
-
3 tbsp olive oil
-
2 tbsp balsamic vinegar
-
1 tbsp soy sauce or tamari
-
1 tsp Dijon mustard
-
2 garlic cloves, minced
-
½ tsp dried thyme
-
½ tsp sea salt
-
¼ tsp black pepper
Instructions
-
Prepare the mushrooms by gently cleaning them with a damp paper towel. Remove the stems and scrape out the gills if desired for more room to absorb flavor.
-
In a bowl, whisk together olive oil, balsamic vinegar, soy sauce, mustard, garlic, thyme, salt, and pepper.
-
Place mushrooms in a shallow dish and pour the marinade over them. Let sit for at least 15 minutes, flipping once to coat both sides.
-
Preheat your grill to medium-high.
-
Grill mushrooms cap-side down for about 4–5 minutes, then flip and grill another 4–5 minutes, until tender and juicy.
-
Serve warm, either whole, sliced over a salad, in a bun like a burger, or as a savory side dish.
Sarah’s Tips
-
No grill? Use a grill pan or cast-iron skillet indoors.
-
Make it a meal: Serve on a toasted bun with avocado, tomato, and arugula for an epic veggie burger.
-
These also work great sliced into pasta, grain bowls, or on top of toast with hummus.
-
Want a little kick? Add a pinch of red pepper flakes to the marinade.
