- Yield
- 4 stacks
Ingredients
- 4 large portobello mushroom caps, stems and gills removed (about 8 oz or 225 g)
- 2 medium zucchinis (about 12 oz or 340 g), sliced lengthwise into 1/4-inch (6 mm) strips
- 3 tablespoons olive oil, divided
- 2 cloves garlic, minced
- Salt, to taste
- Freshly ground black pepper, to taste
- 1/4 cup balsamic vinegar (60 ml)
- 1 tablespoon pure maple syrup or honey (use maple syrup for strict vegan)
- Fresh basil leaves, for garnish (optional)
Instructions
- Prepare the Vegetables In a small bowl, combine 2 tablespoons olive oil, minced garlic, salt, and pepper. Brush this mixture over both sides of the portobello mushrooms and zucchini slices. Let them marinate at room temperature for 10 minutes.
- Grill the Vegetables Preheat a grill or grill pan over medium-high heat. Brush the grill with the remaining 1 tablespoon olive oil to prevent sticking. Grill portobello mushrooms for about 5-6 minutes per side until tender and slightly charred. Grill zucchini slices for 2-3 minutes per side until grill marks appear and they are tender but not soft.
- Make the Balsamic Reduction In a small saucepan, combine balsamic vinegar and maple syrup. Bring to a simmer over medium heat and cook until reduced by half and syrupy, about 5-7 minutes. Remove from heat and let cool slightly.
- Assemble the Stacks On a serving plate, layer: 1 portobello mushroom cap, then 2-3 zucchini slices, then repeat to form stacks. Drizzle each stack generously with the balsamic reduction. Garnish with fresh basil leaves if desired.
Helpful Tips
- Marinating the vegetables adds flavor but do not over-marinate as zucchini can become watery.
- Use fresh, firm portobellos and zucchinis for the best texture.
- The balsamic reduction can be made ahead and stored in the refrigerator cooled to room temperature, then gently warmed before using.
Storage and Make-Ahead
Store any leftover stacks uncovered in the refrigerator and consume within 2 days for best texture.
Keep the balsamic reduction separately in an airtight container; reheat gently before serving.
This dish is best served fresh and not recommended for freezing.
