We're flipping the script and marinating after grilling. Inspired by the technique called escabèche, where cooked fish and meat are preserved in an acidic mixture, we're cooking first, marinating second. In the case of squash, it produces maximum flavor without compromising char or texture. To ensure that the squash is crisp-tender, do pull it off the grill as soon as it's picked up some grill marks and a paring knife easily slips through the flesh.


4 servings

1/2 cup plus 3 Tbsp. extra-virgin olive oil, plus more for grill
1 garlic clove, finely grated
1/4 cup white wine vinegar
4 medium summer squash and/or zucchini, cut lengthwise 1/4" thick
1 medium red onion, cut through root end into 8 wedges
2 bay leaves
Kosher salt, freshly ground pepper
8 oz. feta, crumbled into large pieces
4 banana peppers from a jar, thinly sliced crosswise
Generous pinch of crushed red pepper flakes

Step 1

Prepare a grill for medium-high heat; lightly oil grate. Whisk garlic, vinegar, and 1/2 cup oil in small bowl to combine; set marinade aside.

Step 2

Toss squash, onion, and bay leaves on a rimmed baking sheet with remaining 3 Tbsp. oil to coat; season generously with salt and black pepper.

Step 3

Arrange squash and onion on grate. Grill squash, undisturbed, until grill marks appear, about 3 minutes. Turn over and grill on second side until tender and starting to release liquid, about 2 minutes. Transfer squash back to baking sheet. Grill onion, turning occasionally, until tender and charred around the edges, about 5 minutes. Transfer back to baking sheet.

Step 4

Arrange squash, onion, bay leaves, and feta on a rimmed platter and pour reserved marinade over. Scatter banana peppers on top and sprinkle with red pepper flakes. Let sit at least 15 minutes and up to 1 hour before serving.

How would you rate Grilled Summer Squash and Red Onion with Feta?

  • No peppers, I added chopped fresh oregano to the mix and we liked it very well. I wonder if a splash of lemon juice might be awesome as well. The mandoline was awesome at making those long thin planks of zucchini.

  • The banana peppers and feta perfectly complimented the rest of the dish. I used a grill basket and cooked the squash a bit longer than the author recommended.

  • I absolutely loved this recipe, though I cut the oil WAY back to just 2 tbsp. I think this would be a little upsettingly oily if the full amount were used. I followed the rest of the recipe as written and it was absolutely delicious. Be sure to seek out a nice feta– it’s worth it.
