Ingredients

- ½ cup extra virgin olive oil
- 3 tablespoons balsamic vinegar
- 2 tablespoons soy sauce,low sodium preferred
- 2 cloves garlic,minced
- 1 teaspoon smoked paprika
- 1 teaspoon ground black pepper
- ½ teaspoon kosher salt
- 1 tablespoon fresh rosemary,finely chopped

- Fresh arugula or baby spinach,for garnish
- 1 medium red onion,thinly sliced and lightly grilled
- Tomato slices,ripe and juicy
- Condiments: your favorite aioli,mustard,or vegan mayo
Instructions
- Prepare the Mushrooms: Wipe each portobello gently with a damp cloth to remove dirt.Remove and discard the stems to create a perfect cavity for absorbing marinades.
- Make the Marinade: In a medium bowl, whisk together olive oil, balsamic vinegar, soy sauce, minced garlic, smoked paprika, black pepper, salt, and rosemary until well combined. This mix will infuse the mushrooms with a delightful smoky and herbal flavor.
- Marinate the Mushrooms: place the mushrooms cap side down in the marinade. Use a brush or spoon to coat the tops as well. Cover and refrigerate for 30 minutes to 1 hour, turning them once halfway through to ensure even absorption.
- Preheat Your Grill: Heat the grill to medium-high (around 375°F/190°C). If using a grill pan indoors, add a touch of oil to prevent sticking.
- Grill the Mushrooms: Place the mushrooms on the grill, cap side down first. Grill for about 5 minutes, then flip and grill for another 5 minutes with a slice of cheese on top if using. Watch closely to prevent burning; the mushrooms should be tender, juicy, and beautifully charred.
- Toast the Buns: in the final minutes,toast your burger buns lightly on the grill until golden and slightly crisp.
- Assemble Your Burgers: Spread condiments on your buns, layer with fresh arugula or spinach, the grilled portobello, tomato slices, and grilled red onions. Add extra seasoning or pickles for crunch.
- Serve Immediately: serve your burgers hot, paired with your favorite side salad or sweet potato fries for a complete and satisfying meal.
tips for Success
- Choosing Mushrooms: Look for portobellos with firm caps, deep brown color, and no slimy spots. Larger mushrooms provide a better “burger” size.
- Marinade Variations: Swap balsamic vinegar for red wine vinegar or lemon juice to brighten flavors. Add a teaspoon of maple syrup or honey for a subtle sweetness.
- Cheese Options: Vegan cheeses melt wonderfully with mushrooms but try smoked gouda or provolone for extra smoky depth.
- Make-Ahead: marinate mushrooms up to 4 hours in advance and refrigerate tightly covered. Bring to room temperature before grilling to ensure even cooking.
- Grill Tips: Avoid piercing mushrooms with a fork to retain juices. Use tongs to flip gently.
