How to Serve Grilled Zucchini

  • Serve as a side dish along with grilled meats, chicken or seafood. It’s great when served with some grilled salmon. or you can cook the salmon on a grill pan.

  • Add it to a pizza as a topping. Just chop it up and you’re ready to have a pizza party.
  • Chop it up and add it to a salad like our popular grilled zucchini salad.
  • For best flavor, try to use fresh garlic cloves but garlic powder will work if that is what you have on hand. (Make-ahead garlic tip: crush or mince a bunch of garlic ahead of time. Place it in a jar and cover with oil, then store it in the fridge until you are ready to use for any recipe.)

Garlic Grilled Zucchini

Zucchini is so quick and easy to grill. The key is to slice it to the right thickness. It will shrink when grilled, so don’t slice too thin or else you’ll be left with nothing but a charred shell. Our preferred thickness is about 1/2″ before grilling. Gives a nice slightly charred surface and just enough tender zucchini on the inside.
