Ingredients:

For the Grilled Mushrooms

• 4 large portobello mushroom caps
• 1/4 cup extra virgin olive oil
• 2 tablespoons balsamic vinegar
• 1 tablespoon steak seasoning

For the Bruschetta Topping

• 1 cup Roma tomatoes, seeded and diced (about 3–4 tomatoes)
• 1/4 cup fresh basil leaves, finely chopped
• 1 1/2 tablespoons extra virgin olive oil
• 1 1/2 tablespoons balsamic vinegar
• 1/4 cup freshly grated Parmesan cheese
• 1 garlic clove, finely minced or microplaned
• Salt and black pepper, to taste

Directions:

1. Remove the stems from the portobello mushrooms using a small knife. Gently scrape out the gills with a spoon. Rinse the caps under cold water and pat dry thoroughly.
2. In a large zip-top bag, combine olive oil, balsamic vinegar, and steak seasoning. Seal and shake to mix well.
3. Add the mushrooms to the bag, seal, and gently toss to coat evenly. Press out excess air and let marinate at room temperature while preparing the bruschetta topping.
4. To make the topping, combine tomatoes, basil, olive oil, balsamic vinegar, Parmesan cheese, garlic, salt, and pepper in a bowl. Mix well and set aside.
5. Preheat a grill or grill pan over medium-high heat. Lightly oil the grates or spray the pan with nonstick spray.
6. Place the mushrooms on the grill, gill side up, and cook for 3–4 minutes until grill marks form. Rotate halfway through for crosshatch marks if desired.
7. Flip the mushrooms and grill for another 3–4 minutes until tender, brushing the tops with some of the remaining marinade.
8. Transfer the mushrooms to a paper towel–lined plate and let rest for 5 minutes to drain excess moisture.
9. Serve the grilled mushrooms topped generously with the bruschetta mixture.

Tips

• Pat the mushrooms dry well after washing to help them grill properly.
• Avoid over-marinating, as mushrooms absorb liquid quickly.
• Use large, firm portobello caps for the best texture and presentation.

Variations and Substitutions

• Herb Swap: Use parsley or oregano instead of basil.
• Cheese Change: Try shaved mozzarella or crumbled feta for a different flavor.
