I love to grill vegetables, and this summer I’ve been hooked on this great recipe for summer squash planks with a herbaceous, bright, and zingy basil vinaigrette.
Besides not having to turn the oven on, I think grilling summer squash gives it the best flavor!
The slight smokiness comes from the interaction of the zucchini with the grill’s heat, which imparts a depth of flavor that you wouldn’t get from simply sautéing or steaming the vegetable. The grilling process caramelizes the natural sugars in the summer squash, and the exterior gets charred and slightly crispy, providing a contrast in texture to the tender interior.

Brushing the summer squash with zesty, zippy Basil Vinaigrette while it’s still warm allows all those wonderful flavors to soak in, making it the perfect summer side dish for rotisserie chicken on the grill or grilled bone-in pork chops.
The vegan vinaigrette is different from pesto in the best way, with a slight tang from red wine vinegar and umami from garlic, capers, and nutritional yeast. Made in a blender or food processor, it’s ready in just 5 minutes.

Summer squash and zucchini are nearly identical besides their color – summer squash tends to be slightly sweeter than zucchini, but both have an overall mild flavor.
And yes, the skin of summer squash is very thin and tender so it can be eaten! This makes it very quick to prep for meals too, as no peeling is required.
It’s much easier to grill squash when you cut it into planks rather than rounds, which can fall through the grates. The long planks mean you’re able to get a lot of surface area onto the grill, giving the squash great flavor. You don’t need a grill basket either!
When testing, 1/4 inch was the perfect thickness for the summer squash planks. It stays nice and sturdy on the grates, but doesn’t take forever to cook through. When cut thicker than that, the texture never got as tender and had more of a vegetal, raw flavor.
Simply cut the stem end of the squash off, then use a chef’s knife to cut vertically into 1/4 inch planks. That’s it!

Hi- have you done this on an inside grill skillet if a grill isn’t available?
