Ingredients (Serves 4)
For the Zucchini:
- 4 medium zucchinis
- 2 tablespoons olive oil or avocado oil (or sesame oil for extra Asian flair)
- Salt and freshly ground black pepper, to taste
For the Spicy Asian Sauce:
- 3 tablespoons low-sodium soy sauce or tamari (for gluten-free)
- 1 tablespoon toasted sesame oil
- 1 tablespoon rice vinegar or fresh lime juice
- 1–2 teaspoons honey or maple syrup (adjust for desired sweetness)
- 2 garlic cloves, minced
- 1 tablespoon fresh ginger, grated
- 1–2 tablespoons sriracha, sambal oelek, or chili garlic sauce (adjust to your spice preference)
- 1 teaspoon sesame seeds (plus more for garnish)
Garnishes:
- 2 green onions, thinly sliced
- Extra sesame seeds, toasted (optional)
- Fresh cilantro or Thai basil (optional, for extra freshness)
Instructions
- Preheat the grill: Heat your outdoor grill or grill pan to medium-high heat (about 400°F/200°C). Lightly oil the grates to prevent sticking.
- Prepare the zucchini: Wash and trim the ends of the zucchinis. Slice each lengthwise into ¼-inch thick planks (or 2–4 planks per zucchini depending on size). Brush both sides generously with oil and season with salt and pepper.
- Grill the zucchini: Place the slices on the hot grill. Cook for 3–5 minutes per side, or until tender, with nice char marks and grill lines. Avoid overcooking to keep them from becoming mushy.
- Make the sauce: While the zucchini grills, whisk together all the sauce ingredients in a small bowl until well combined. Taste and adjust spice, sweetness, or saltiness as needed.
- Assemble and serve: Arrange the grilled zucchini on a serving platter. Drizzle the spicy Asian sauce generously over the top (or serve it on the side for dipping). Sprinkle with sliced green onions and extra sesame seeds. Serve immediately for the best texture.
