Ingredients for grilled portobello mushrooms recipe
- 2 large portobello mushroom caps
- 2 tablespoons olive oil
- 1 teaspoon smoked paprika
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1 teaspoon sea salt
- 1/4 teaspoon black pepper
- 1 tablespoon melted butter
- 1 tablespoon lemon juice
- 1 teaspoon dried thyme
- 1 tablespoon tamari
- 1 tablespoon honey
You can absolutely swap the smoked paprika for regular paprika if that’s what you’ve got on hand. Some people add extra garlic but I personally think the balance here is perfect, though taste and adjust as you go.
The beauty here? Everything comes together into one simple marinade that does all the heavy lifting. Don’t skip the lemon juice—it brightens everything up and keeps things from tasting one-note. These grilled portobello mushrooms are way more forgiving than you’d think, so don’t stress if your measurements aren’t exact.
Step-by-step instructions
1. Clean your 2 portobello mushroom caps by gently wiping them with a damp paper towel to remove any dirt. Carefully scoop out the dark gills with a spoon, using firm pressure but being gentle so you don’t crack the caps. Pat everything dry—moisture is the enemy of that golden sear you’re after.
2. Mix your olive oil, smoked paprika, garlic powder, onion powder, sea salt, black pepper, melted butter, lemon juice, dried thyme, tamari, and honey in a small bowl. Whisk until everything combines into one cohesive marinade that smells absolutely incredible. This marinade is what transforms plain portobello mushrooms into something special.
3. Place your mushroom caps gill-side up in a shallow dish and brush the marinade generously all over both sides. Let them sit for at least 5 minutes so the flavors can actually penetrate the caps. I like to do this step while my grill heats up—perfect timing.
4. Preheat your grill to medium-high heat, around 400°F, and lightly oil the grates so nothing sticks. You’ll know it’s ready when you can hold your hand over it for only 2-3 seconds before pulling away. Don’t skip this step because proper heat is what creates those gorgeous char marks.
5. Place the mushroom caps gill-side down on the grill and let them sit for 5-6 minutes without moving them. Resist the urge to poke or flip—that’s how you get beautiful grill marks and caramelization. You’ll hear them sizzle which means things are happening right.
6. Flip the caps carefully using tongs and grill the other side for another 4-5 minutes until the flesh gets tender and releases easily when pierced. The mushrooms should look slightly collapsed but still hold their shape. The kitchen’s gonna smell absolutely amazing at this point, trust me.
7. Transfer your grilled portobello mushroom recipe creation to a plate and let rest for 2 minutes before serving. This allows the juices to redistribute so they don’t run all over when you cut into them. Taste one and adjust seasoning if needed—that’s totally normal.
