    Let us discover the simple, yet delightful world of grilled zucchini, along with a few ideas to enhance this delicious dinner idea. Don’t forget your apron!

    1. A Few Facts About Zucchini

    Zucchini is a type of summer squash. It belongs to the same family as cucumbers and gourds, and it usually comes in a dark green color with an elongated shape. The flavor is quite soft, adapting to the technique and ingredients used to cook it.

    The first thing you should know about zucchini is that the whole fruit is edible and nutritious: the skin, the flesh, and the seeds.

    The second thing you should know is that it is high in fiber, low in calories, and has vitamins that help boost the immune system and improve vision, gut health, and blood sugar levels.

    Zucchini is in season during the summer months. 

    2. How To Grill Zucchini

      1. The formula for a perfect grilled zucchini starts with choosing the best specimens.  Seasonal vegetables taste better. The best zucchini are harvested in summer. Choose small, brightly colored zucchini. Medium zucchini, smaller than 15 centimeters, are firmer, have more and better flavor, and their skin is edible, so there is no need to peel them. They also have smaller seeds, which is more appetizing for some people.
      2. Preheat grill to medium-high. The grill grate should already be clean and oiled. You could use either a charcoal grill or an indoor grill pan.
      3. Place zucchini on a cutting board and slice the zucchini into 1/4-inch thick elongated strips using a sharp, good-quality knife. Thicker, uniform zucchini strips have more consistency and will grill evenly; they are easier to handle and will not fall through the grate. Also, wider pieces will have more space for grill marks, where all the smoky flavor concentrates. 
      4. Rub both sides of each zucchini slice with olive oil and whatever seasoning you prefer (like lemon, garlic, basil, etc. More on that later). Olive oil helps the spices and seasonings to adhere and is also the key to a better browning.
      5. Place zucchini on the grate and grill the zucchini over direct heat. The ideal temperature is about 350ºF.
      6. Your cue will be when those black grill marks appear on the surface. When they start to appear, turn the slices and wait a few more minutes for them to appear on the other side.  This takes approximately 4 to 5 minutes per side. Try to turn the slices only once.
      7. Serve the Zucchini with drizzled vinaigrette. 

      Zucchini can be sliced and prepared a day ahead and kept in the refrigerator until the next day.

      How do you prevent zucchini from getting soggy?

      Because zucchini is 90% water, there is always some degree of risk that it ends up too soggy. There are a few things you can do to help your chances with any grilled vegetable:

      • Cut larger pieces. Larger pieces will retain more water.
      • Some people say you should add salt at the end, instead of the beginning. Others say it’s best to salt zucchini ten minutes before cooking and let the zucchini sweat. The important thing is salt and pepper! not only in terms of flavor; salt is important to pull out the moisture and achieve a better texture. 
      • Don’t overcook them. It shouldn’t take longer than 4-5 for each side to be ready.

      3. The Best Easy Grilled Zucchini Recipe

      To be fair, I don’t know if this one is the best. There may be several “bests” because grilled zucchini is a simple, delicious, fool-proof, and easy recipe. 

      But I enjoy this one very much and I think it’s a sure shot if you’re looking to try your first grilled zucchini recipe.


      Prep Time

      Around 3 hours to marinate, 10 minutes to prepare and 8 minutes for cooking time 


      • 3 sliced zucchini in ½ inch long strips
      • 2 yellow squash cut in the same length
      • ⅓ cup olive oil
      • 1 tablespoon garlic powder
      • 2 tablespoons freshly squeezed lemon juice
      • 2 tablespoons white wine vinegar (or herbed vinegar for even more flavor)
      • 2 teaspoons finely chopped fresh thyme (this one is optional, and some prefer oregano, mint, or tarragon)
      • Salt and pepper to taste
      1. Mix the oil, lemon juice, vinegar, garlic powder, salt, pepper, and your other spice of choice (I do love it with thyme) to prepare a vinaigrette. Some people like balsamic vinegar too. Set about three tablespoons aside. 
      2. Marinate the zucchini and yellow squash in the vinaigrette at least three hours ahead of time at room temperature, or even overnight in the refrigerator. A zip-lock bag works great here. Stir them to mix and soak them well.
      3. Heat the grill over medium-high heat. When hot, lightly oil the grates.
      4. Place the zucchini and squash perpendicular to the grates to get those sought-after grill marks.
      5. Grill the zucchini for about 4-5 minutes on each side, until the zucchini is tender, brown, and crisp.
      6. Serve the zucchini on a platter and drizzle with the reserved vinaigrette.
      7. Grilled zucchini can be served warm or at room temperature. Add some lemon wedges!

      • Roasted nuts
      • Seeds

      • Capers
      • Ranch dressing
      • Green creamy dressing
      • Kosher salt
      • Freshly ground black pepper
      • Basil / Fresh basil leaves
