Every year when the weather turns warm, cooking grilled vegetables on our back porch becomes my side dish haven. When I’m standing outside sipping wine with one hand and flipping Grilled Portobello Mushrooms with the other, it feels as if whatever else happened that day, everything is going to be OK as long as I can still do this quiet, blissful thing for myself.
Ever since learning to make Grilled Cauliflower Steaks, I’ve been completely enamored by the delicious simplicity of grilled veggies. It’s the same way I feel about roasted vegetables in the winter—10 minutes of effort for a plate piled high with scrumptious, healthy satisfaction.
Grilled portobello mushrooms have a mega advantage over baked portobellos mushroom recipes: NO clean up at the end!
Simple Grilled Portobello Mushrooms
To make these delicious marinated grilled mushrooms, you’ll need one main ingredient (ahem, the portobellos) and a few simple ingredients for the marinade.
- Portobello Mushrooms. One of the things I love most about portobello mushrooms is their “meaty” factor. I realize that probably sounds a bit odd because HELLO we are talking about a vegetable, but in kingdom veg, portobello mushrooms are especially satisfying, especially when grilled.
You’ll definitely want to clean the mushrooms before making this recipe.
- To Clean Portobello Mushrooms: Start by removing and discarding the stems. With a paper towel, gently rub off any dirt from the caps. With a small spoon, lightly scrape around the underside of the caps to remove the gills. The gills are edible but, well, weird and when you are sauteing with them, they’ll turn your recipe a dark, unappetizing hue. If the gills don’t bother you, you can leave them on.
The key to mega mushroom success is to enhance their flavor with a basic portobello mushroom marinade that plays up the portobellos’ earthy and (to use a word that’s both super foodie and super accurate) umami factor.
How to Cook a Portobello Mushroom
If this is your first time ‘shrooming it, fear not! You can cook these on an indoor or outdoor grill, and because we aren’t fussing with internal temperatures, you don’t need to stress over food safety.
- In a shallow dish, whisk together the marinade ingredients. Choose a dish large enough to hold the mushrooms in a single layer.
- Add the mushrooms to the marinade, coating both sides. A quick 10 minutes marinade time is all you need, though you can let them go for up to 30 if you are otherwise busy drinking wine prepping other elements of the meal. Don’t go longer than 30 or the portobellos will become too salty.
- Place the mushrooms on the grill, and brush them with the marinade as they cook.
- Cook for 3-4 minutes on each side. BOOM. Dinner, done.
You can serve these grilled portobello mushrooms on their own or with a hearty topping like the Herby Avocado Sauce used to top this Cauliflower Steak (SO GOOD).
This recipe also works well for a grilled portobello mushroom burger. Stack each grilled mushroom on a bun with a slice of cheese (I like provolone, fontina, or if I’m being really fancy, gouda), a juicy slice of fresh summer tomato, and a small handful of arugula. Go ahead and add avocado too because GRILLED VEGETABLES, BEST LIFE. For an extra gourmet version, give this stuffed, double-stacked Portobello Mushroom Burger a try.

Grill: Place the skewers on the grill grates and cook for about 10 minutes, until tender. Spritz: Squeeze juice from lemon wedges onto the mushrooms before serving!
How do you keep mushrooms moist on a grill?
An oil-based marinade will help lock in moisture. If you choose not to marinate the mushrooms, the mushrooms can be seasoned right on the grill. Mix a small amount of olive oil, garlic, salt, and other seasonings and baste (or mop) this onto the mushrooms as you cook them. Basting while grilling will also keep your mushrooms moist.
How long should mushrooms soak before grilling?
If you’re using a marinade, allow your mushrooms to soak for at least 20 minutes at room temperature. Your mushrooms should retain the moisture from the marinade and may not require oil when on the grill but keep an eye on them to make sure you get the perfect BBQ mushrooms.
Can You Grill mushrooms without oil?
If you don’t like oil, don’t worry! While grilling mushrooms with oil and seasoning is a popular method, it’s not the only option. Some grill masters prefer to marinate mushrooms for grilling. You can soak your mushrooms in your favorite marinade prior to grilling for a delicious flavor.
