I hope you’ll try these grilled vegetables with cumin yogurt sauce for a light summer dinner, or for a party as a side.  It’s all really quite easy.

The zucchini and summer squash get either broiled  in a hot oven, or grilled until the flesh inside yields just slightly.  To finish, it gets a good dose of chopped parsley and a drizzle of cumin scented yogurt sauce, which rounds out the flavors and unites the whole.

Don’t let the simplicity of the recipe fool you, it has big flavors.  Grilling/broiling the zucchini and summer squash adds a hint of smoky flavor that pairs nicely with the earthy, nutty taste of the cumin and tahini in the yogurt sauce.

You can make the yogurt sauce a few days ahead of time and leave it in the fridge.  But, that doesn’t quite capture the benefit. What’s really happening during that quality time is the mingling together;  the longer it rests, the more time the flavors have to combine.

The flavor of this sauce is bright but rich and Greek yogurt, makes it extra creamy and tangy, while still keeping it light.

I  love the contrast between the warm squash and cool yogurt sauce, the subtle nuttiness of the lightly spiced sauce works beautifully with zucchini and summer squash, but I would venture it would be wonderful with all kinds of vegetables.

    I love enjoying the simplicity of vegetables like this, either roasting or grilling them to bring out their perfect flavors. The perfect summer party side! Lovely!

    Wow, some people got up REALLY early this morning to read/comment on your blog! 😉

    Sylvie, this is lovely. We grilled marinated veggies all summer. I usually just put them in some sort of vinaigrette before grilling.

    But your sauce sounds amazing! I will definitely be trying this.

    I really think this is such a fresh and pure dish. You photographs really looks beautiful. Already pondering if this yogurt sauce will go well with grilled butternut?

    I’ve been starving all morning. I have a giant bag of zucchini and summer squash on my kitchen counter from the market that had no predetermined plan. Thanks for the lunch inspiration.

    Sylvie, I am loving yogurt sauce lately. This sounds so good. I just made a warm beet salad last night with yogurt sauce (garlic, cumin and coriander).

    We have been grilling our zucchinis from our yard this year!!The cumin yogurt is just perfect for summer time. Lovely way to enjoy the summer veggies!

    Great pictures as always…an absolute summer recipe. I make something similar with yogurt,I add up some finely chopped onions and cilantro with it.

    What a perfect summer plate, Sylvie! Exactly what we like. Light veggies (which could be easily done on a grill too) and a fabulous yogurt sauce. Love the cumin and the lemon makes it so nice and summery.

    Love this type of yogurt sauce. I would add it to vegetables or meat. Wonderful summer dish . Happy midsummer!!!

    I always add a little cumin to tzatsiki as yoghurt and cumin works wonderfully together. This looks like the perfect courgette dish and would happily serve it at a dinner party, yum!

    Oh boy I love this! We used to eat something very similar at a wonderful little Turkish restaurant and you brought the memory of the taste all back to me. Bookmarked! Thank you for sharing this!

    This is my favorite kind of recipe – using up the fresh veggies of summer in a new and unique way with awesome flavors. I’ll definitley give it a try! Thanks for sharing!

    I love yoghurt sauce especially since I eat spicy foods a lot and the yoghurt really helps to cool everyhting down. The addition of tahini is genius- must try!!

  17. says

    I have been thinking of bringing some veggie dishes to a bbq party that my friend is hosting. This is actually perfect! I love the sound of yogurt cumin sauce. I’ve never tried it before, but I love cumin so I just imagine the flavor and I’m in love. Beautiful photography as always, Sylvie!

    I used to have a decent size garden and about now the zucchini and yellow squash would be out of control and new recipes were a welcome addition as we had them several times a week. Now I just buy what I need and I do believe I need this!

    I barely touch my oven in the summer though…mine would be grilled veggies and your fabulous sauce!
