Tuscan Grilled Zucchini & Summer Squash

August  2, 2009
Author Notes

I came up with this recipe one day after harvesting some squashes and herbs from my home garden. The marinade can be tweaked with any woodsy herb and substituting a different vinegar or citrus juice. A super hot grill and sturdy skewers are key... —Stefano Coppola

Test Kitchen Notes

This dish is a great example of the whole equaling more than the sum of its parts. At first glance, this recipe seems simple enough, but we've never tasted grilled zucchini quite like this. The porous squash soaks up the lemon, garlic, herbs and chili in the marinade, and after a quick char on the barbecue, it's positively bursting with flavor. Add the soft, mellow sweetness of red onion grilled in its own skin and you've got a bowl of vegetables that's addictive. You'll have leftover marinade, which is a good thing: reuse it to grill more veggies or drizzle over a salad. Stefano Coppola doesn't specify this, but we marinated the squash at room temperature. We also seasoned the skewers generously with salt and pepper before throwing them on the grill, adding a bit more seasoning later along with a tablespoon of oil from the marinade. - A&M —The Editors
