Grilled Zucchini and Yellow Squash with Champagne Vinaigrette


When the summer sun casts its warm glow, it’s time to fire up the grill and embrace the joys of outdoor cooking. Grilling isn’t just about meat; it’s an opportunity to celebrate the vibrant flavors of seasonal vegetables. In this culinary adventure, we’ll explore the art of grilling zucchini and yellow squash to perfection, and then elevate their natural essence with a touch of elegance through a Champagne vinaigrette. Get ready to tantalize your taste buds with a dish that marries simplicity and sophistication.

Grilling Zucchini and Yellow Squash:

A Symphony of Flavor

Zucchini and yellow squash, members of the Cucurbitaceae family, lend themselves beautifully to grilling. Their mild, slightly sweet flavors are enhanced by the smokiness of the grill, resulting in a medley that boasts both depth and freshness. The high heat of the grill caramelizes the natural sugars in these vegetables, creating a delicate balance of sweetness and savory notes that dance on the palate.

To prepare these delectable vegetables for grilling, simply slice them lengthwise into uniform pieces. A light brush of olive oil, a sprinkle of salt and pepper, and your zucchini and yellow squash are ready to be transformed into culinary masterpieces.

The Allure of Champagne Vinaigrette

Elevating a dish to a new level of sophistication often comes down to the art of dressing. Champagne vinaigrette, a marriage of light, effervescent Champagne vinegar with a touch of Dijon mustard, finely minced shallots, and high-quality olive oil, creates a dressing that is both luxurious and refreshing.

The Champagne vinegar adds a subtle, tangy brightness that complements the grilled vegetables, while the Dijon mustard acts as a binding agent, harmonizing the flavors. Shallots provide a delicate onion flavor, and the olive oil rounds out the vinaigrette with a luscious mouthfeel. The result is a dressing that enhances the inherent flavors of the dish without overwhelming them.

When summer rolls around and the farmers market is teeming with zucchini and yellow squash, there’s only one solution: grill it up!

In this recipe I leveled up and combined the squash with briny sheets of feta, a simple garlicky vinaigrette, and then threw on some fresh basil and mint to serve.

The dish hits all the right notes: salty, herby, and just a little bit sweet. It’s a 20-minute sleeper hit!

What to Look for When Buying Squash
Whether you’re buying your yellow squash and zucchini at the grocery store or the farmers market, there are a couple things you should keep in mind. You want to look for small or medium sized squash—larger squash tend to have bitter seeds and a more fibrous skin. Also, look for squash that is free of puncture marks, as they tend to go bad faster.

What Kind of Feta Should You Use?

Buy the blocks of feta that come in a brine instead of the pre-crumbled stuff—it makes a big difference. The brined feta is going to be more moist and flavorful, whereas the pre-crumbled feta can be dry and hard. I promise it’s worth the couple extra seconds it takes to cut or crumble it yourself!

My Favorite Way to Repurpose Leftovers

I recommend making a double batch of this recipe and repurposing it throughout the week! It’s a great addition to a lunch quesadilla, or in a simple pasta for dinner.

Grill the zucchini and squash:

Arrange the squash in a single layer on the grill and grill for 8-10 minutes, turning halfway through using tongs.

Once grill marks appear on both sides and the squash is cooked, remove from the grill. (Slice the zucchini and yellow squash into 1-inch pieces if you desire). Transfer to a serving platter.

While you’re grilling the vegetables, make the vinaigrette. In a small jar with a lid, add the lemon juice, champagne vinegar, olive oil, garlic, shallot, and salt and black pepper, to taste. Close the jar and shake vigorously until the vinaigrette is well combined, about 30 seconds. Set aside until ready to use.
