Step-by-Step Instructions for Grilled Portobello Mushrooms Recipe
Here’s how to make these tender, smoky mushrooms step by step:
- Prepare the Mushrooms: Gently clean 4 large portobello mushroom caps with a damp paper towel. Remove the stems and scrape out the gills with a spoon for a smoother flavor.
- Tip: Removing the gills helps the mushrooms absorb the marinade better and reduces bitterness.
- Make the Marinade: In a small bowl, whisk together 1/4 cup olive oil, 2 tablespoons balsamic vinegar, 2 cloves minced garlic, 1 teaspoon chopped fresh thyme, and salt and pepper to taste.
- Optional Add-In: A dash of soy sauce or Worcestershire sauce adds depth.
- Marinate the Mushrooms: Place the mushroom caps in a shallow dish, gill side up, and pour the marinade over them. Let them marinate for 10-15 minutes, flipping halfway through.
- Serving Idea: Longer marination (up to 30 minutes) enhances flavor if you have time.
- Preheat the Grill: Preheat your grill to medium-high heat (about 400°F) and lightly oil the grates to prevent sticking.
- Pro Tip: If using a stovetop grill, preheat for a few minutes for even cooking.
- Grill the Mushrooms: Place the mushrooms on the grill, gill side up, and cook for 4-5 minutes. Flip and grill for another 3-4 minutes, or until tender and lightly charred.
- Serving Idea: Brush with extra marinade while grilling for added moisture.
- Serve and Enjoy: Remove the mushrooms from the grill and serve warm, garnished with fresh herbs if desired.
- Optional Topping: Add a sprinkle of Parmesan or crumbled feta for extra flavor.
Extra Tips and Variations
- Make it Spicy: Add red pepper flakes to the marinade for a kick.
- Add Cheese: Top with cheese after grilling and broil for a melted finish.
- How to Store: Store leftovers in the fridge for up to 2 days.
- Serving Suggestion: Serve on a bun with toppings for a portobello burger.
