Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the Portobello Steaks

• 4 large portobello mushroom caps, stems removed
• 3 tablespoons olive oil
• 2 tablespoons balsamic vinegar
• 2 tablespoons soy sauce
• 2 garlic cloves, minced
• 1 teaspoon Dijon mustard
• 1 teaspoon smoked paprika
• 1 teaspoon dried thyme
• 1/2 teaspoon black pepper
• 1/4 teaspoon salt

For the Vegetables

• 2 zucchini, sliced
• 2 bell peppers, cut into strips
• 1 red onion, cut into wedges
• 1 cup asparagus spears
• 1 tablespoon olive oil
• Salt
• Freshly ground black pepper
• Fresh parsley, chopped, for garnish

Directions

1. I whisk together the olive oil, balsamic vinegar, soy sauce, garlic, Dijon mustard, smoked paprika, thyme, salt, and pepper in a shallow dish.
2. I place the portobello mushroom caps in the marinade and let them soak for about 20 to 30 minutes, turning them halfway through.
3. I preheat the oven to 425°F (220°C) or heat an outdoor grill to medium-high.
4. I toss the zucchini, bell peppers, red onion, and asparagus with olive oil, salt, and pepper.
5. I roast the vegetables for 20 to 25 minutes, or grill them until they’re tender with light char marks.
6. I grill the marinated portobello mushrooms for about 5 to 6 minutes per side, or roast them until they’re tender and juicy.
7. I arrange the vegetables on serving plates and place a portobello steak on top or alongside them.
8. I garnish everything with freshly chopped parsley before serving.

Variations

• I include a drizzle of chimichurri or pesto for a fresh herb finish.
• I replace the balsamic marinade with a garlic-herb or teriyaki marinade for a different flavor profile.

Storage/Reheating

I store the cooked portobello steaks and vegetables in an airtight container in the refrigerator for up to 3 days. I reheat them gently in a skillet over medium heat or in a 350°F (175°C) oven until warmed through. I avoid microwaving the mushrooms for too long because they can become overly soft. If I have leftovers, I also enjoy slicing the mushrooms and adding them to salads, grain bowls, or sandwiches.

FAQs

Can I prepare the mushrooms ahead of time?

Yes. I marinate the portobello mushrooms several hours ahead or even overnight in the refrigerator for deeper flavor.

Do I need to remove the mushroom gills?

I can leave the gills intact, but I sometimes scrape them out with a spoon for a cleaner appearance and a slightly milder flavor.

What vegetables work best with this recipe?

I enjoy using zucchini, bell peppers, asparagus, onions, carrots, broccoli, Brussels sprouts, or eggplant depending on the season.

Can I cook the mushrooms in a skillet?

Absolutely. I cook them in a hot skillet for about 5 to 6 minutes per side until they’re tender and nicely browned.

What can I serve with Portobello Steak with Vegetables?

I like serving it with mashed potatoes, rice, quinoa, couscous, crusty bread, or a fresh green salad for a complete meal.
