Grilled Zucchini Recipe

Aren’t we always looking for an easy dinner side dish?!  I put most of my effort into the main dish, so I LOVE an easy, yummy side that tastes exponentially more delicious than the effort I put into it. Enter this grilled zucchini recipe!

Before this recipe, I served up grilled veggies alongside my favorite proteins seasoned with a little of this and a little of that – I didn’t know what I was missing! I never would have guessed grilled zucchini could taste THIS GOOD. 

This recipe transforms mild, unassuming zucchini into confident, crisp-tender zucchini dressed to impress. It’s the kind of extraordinarily delicious side you want seconds and thirds of so you can inhale its vibrant, bright, garlicky, herbaceous notes once more. 

What zucchini is best for grilling?

Either Black Beauty Zucchini (the most common type) or Gourmet Gold are excellent for grilling but if you can get your hands on Green Griller Zucchini, then you’ve hit the jackpot.  This type of zucchini boasts a fatter, blockier oblong shape which yields broad, more uniform slices that are easy to flip and a texture that holds well after cooking. Its flavor is also deliciously nutty.

WHAT SIZE ZUCCHINI IS BEST FOR GRILLING? 

You can grill any size zucchini but for optimal flavor and texture, I recommend small to medium-sized zucchini.  Small to medium sized zucchini have a fresh, mild flavor with smaller seeds and thinner skins.  Larger zucchini or summer squash can be either flavorless or bitter, stringy, seedy and watery.  Smaller zucchini are also easier to cut into uniform slices.

3 ways to cut zucchini and squash for grilling

How to cut zucchini and summer squash for grilling?  There really is no right or wrong to this answer as long as you cut the zucchini slices at least 1/3-inch thick.  Of course, each shape has their pros and cons:  Here’s a little breakdown:

• Rounds:  slice the zucchini and squash into ⅓ to 1/2-inch-thick rounds.  Although beautiful, I find this shape more of a hassle to cook because there are 4X as many zucchini slices to flip!
• Wedges/Sticks/Batons: cut the zucchini in half lengthwise; place the cut sides down flat on the cutting board and cut it lengthwise in half again to create four zucchini wedges or sticks. This is my second favorite way to cut zucchini because the batons hold their shape well, but they don’t cook quite as evenly and you don’t get that coveted char on all sides.
• Long Planks:  is my preferred method of cutting zucchini (more on how to cut below).  You get a long, even surface area for continual contact with the grill and they are easy to flip.

HOW THICK SHOULD I CUT THE ZUCCHINI BEFORE GRILLING?

When cutting zucchini, take care not to slice them too thin or you’ll end up with soggy zucchini.  Here’s how to cut them for perfectly crisp-tender grilled zucchini every time:

• Lay the zucchini on a cutting board and slice both of the ends off. 
• Cut the zucchini lengthwise into slabs that are about 1/3-inch thick.  
• This could mean 3 or 4 slabs per zucchini.  When in doubt, cut them on the thicker side. 
• Thicker slabs won’t break apart when removing from the grill and grill up crisp-tender instead of mushy.
• If your zucchini is extra-long, you can cut it half crosswise and then into 1/3-inch-thick slabs so it’s easier to flip on the grill. 

Ingredients for grilled zucchini and squash

It doesn’t take much to transform unassuming, mild tasting zucchini and squash into the bold, confident stars they were born to be.  This grilled zucchini recipe uses minimal ingredients but you will be blown away at the flavor. Here’s what you need for grilled zucchini and squash:

• Zucchini: look for zucchini and/or squash that are small to medium-sized (no longer than 6 to 8 inches) for the best flavor and texture. They should be very firm without any give/wiggle so make sure to gently squeeze each zucchini before popping it in your cart.  The skin should be smooth and free of nicks, cuts and bruises and be slightly prickly yet shiny, a key indicator of freshness. Store the zucchini in a plastic bag in the refrigerator crisper drawer without washing first.  Use it as quickly as possible for the best texture, but it should last up to 5 days. If you notice it wilting/becoming soft, use it immediately.
• Olive Oil:  is used in the marinade to add and deliver flavor and coats the zucchini so the exterior can caramelize without sticking to the grill.  Use extra virgin olive oil for the best flavor.
• Lemon:  you will need the juice of one lemon and one teaspoon lemon zest – so please use fresh!  The bright pop of lemon juice highlights the garlic and seasonings and is what makes this recipe truly spectacular. Of course, you can use more or less lemon to taste.
• Garlic:  three cloves of garlic bring the tantalizing garlic-lemon flavor we all know and love and make this recipe taste far more complex that it is.  If you’re in a bind, you may substitute with a heaping ½ teaspoon garlic powder but fresh is best.
• Herbs:  dried parsley and dried basil add a hint of earthiness that rounds out the dish. Feel free to add additional herbs or substitute with 3X the amount of fresh herbs to dried.  You can also swap in your favorite herb blend such as Italian seasonings.
• Salt and pepper:  a must!  They are a key ingredient to great tasting, never bland zucchini.  Kosher salt and pepper are added directly to the marinade but you may also season with additional freshly cracked salt and pepper to taste afterwards if needed. If you use table salt instead of kosher salt, you will need half the amount.

grilled zucchini recipe variations

This recipe is a blank canvas for all sorts of add-ins such as Parmesan, fresh herbs or a drizzle of balsamic. Here are some tasty ideas:

• Use squash!  This recipe works equally well with squash or a blend of both zucchini and squash.
• Make skewers.  Instead of planks or spears, you can thread zucchini rounds onto skewers and grill. 
• Add freshly grated Parmesan.  This nutty, umami adds complex flavor and is always a hit with kids and adults alike.  Sprinkle the Parmesan on after you remove the zucchini from the heat. 
• Add feta.  Sprinkle your platter of grilled zucchini with feta and enjoy the salty, tangy flair.
• Add a drizzle of balsamic.  For a different spin, try swapping half of the lemon juice for balsamic and drizzle the platter with either quality balsamic or sweeter balsamic glaze.
• Add fresh herbs.  Add fresh mint, basil, oregano, thyme, tarragon, etc. directly to the marinade and any additional herbs after grilling to garnish.
• Spice it up.  Add a dash of red pepper flakes to the marinade or sprinkle onto the grilled zucchini for those who like it hot.
• Add pesto.  Add a couple tablespoons pesto to the marinade or drizzle pesto on top of the zucchini before serving.
• Add nuts for crunch.  Sliced almonds, roasted pecans, toasted pine nuts, salt and pepper pistachios, etc. would offer a textural contrast.
• Add panko for crunch.  Sprinkle on buttery toasted panko after grilling. Use this recipe as a guide.
• Add seeds for crunch.  Add seeds such as roasted pumpkin seeds, roasted sunflower seeds, etc.
• Add dried fruit for sweetness.  Sweet and savory is a favorite pairing especially with some crunch!  Add some dried cherries, dried cranberries, dried peaches, raisins, etc.
• Dip, dip, dip!  Dip the tangy grilled zucchini and squash in cooling, creamy tzatziki, ranch sauce or pesto.

Variations:  Try these flavor combos!

Zucchini and squash are mild in flavor which makes them a blank canvas to dress in the flavorings of any type of cuisine – which means they pair well with every type of cuisine. While Mediterranean and Italian are always a favorite paired with lemon juice, you can also swap in your favorite seasonings or seasoning blends paired with lemon juice, lime juice, or a splash of soy sauce or balsamic.  Keep the ¼ cup olive oil then add an acid and seasonings of your choosing.  Here are just a few ideas:

• Asian Grilled Zucchini:  rice vinegar, soy, sesame oil (just a splash) honey sriracha, ginger and garlic garnished with sesame seeds.
• Greek Grilled Zucchini:  red wine vinegar, lemon juice, garlic, oregano, salt, pepper, then top with crumbled feta.
• Mexican Grilled Zucchini : lime juice, chili powder, ground cumin, smoked paprika, cayenne pepper, garlic, salt pepper, etc., then top with crumbled Cotija.
• Cajun Grilled Zucchini:  Cajun seasoning, lime juice, garlic.
• Middle Eastern Grilled Zucchini: half lemon and half balsamic, curry powder, ground cumin, smoked paprika, ground coriander, garlic, salt and pepper.

Variations: try these seasoning blends!

If your seasoning blend contains salt then make sure to reduce the salt in the recipe and then season the grilled zucchini and squash with additional salt to taste after cooking.  Here are some ideas:

• Cajun seasoning
• Creole seasoning
• Fajita Seasoning
• Lemon pepper
• Herbs de Provence
• Everything bagel seasoning
• Butter Garlic seasoning (I’m obsessed with Kinder’s Master Salt)
• Ranch seasoning
• Tarragon
• Chinese 5 spice
• Smoked paprika
• Ground Cumin
• Chili Powder
• Red chili flakes

How to grill zucchini and squash

Now, let’s get to the grilling!  Grilling zucchini is very simple as long as you pay attention to the thickness of your zucchini slices, grill temperature and general timing.  Here’s how to grill zucchini (full measurements in the recipe card at the bottom of the post):

• Slice zucchini.  Cut the zucchini lengthwise into 1/3-inch-thick planks.

• Marinate zucchini. Whisk the olive oil, lemon juice, lemon zest, garlic and seasonings together in a freezer size resealable bag.  Add the zucchini and turn to coat. Marinate for 20 minutes at room temperature or up to 2 hours in the refrigerator.

• Preheat a grill to medium-high heat. That’s about 400 to 450 degrees.  Clean the grill with a wire grill brush and generously grease with oil.
• Grill on the grates for 3 minutes per side, turning once. Cook just until crisp tender, don’t overcook!

Serve immediately. Transfer the zucchini to a platter. For extra flavor, brush with some of the marinade left behind in the bag. Dig in!

More tips FOR SUCCESS

• Slice the zucchini uniformly.  A uniform thickness will help the zucchini and squash grill evenly.
• Slice the zucchini evenly.  If your zucchini isn’t straight, then it won’t lay straight on the grill and won’t caramelize evenly.
• Lay the zucchini on the grill horizontally across the grates.  You can also lay it on a slight bias for diagonal grill marks.  Either of these grilling directions will ensure the zucchini doesn’t slip into the fire.
• Above all else, don’t overcook!  Zucchini can be eaten raw so it doesn’t need much by the way of cooking.  Cook just until crisp-tender and not tender-crisp.  When in doubt, pull the zucchini.  Slightly crunchier zucchini is better than soggy zucchini.
• Undercook the zucchini if using for leftovers.  If you are planning to reheat the zucchini in another recipe like pasta or rice, then slightly undercook it by a couple minutes, then cook it to the desired tenderness in the final dish.
• Use an indoor grill pan in the winter or if you don’t have a grill.  This one works great.

How to store zucchini

• To Store: refrigerate grilled zucchini in an airtight storage container for up to 3 days in a single layer or with parchment in between the layers.
• To Reheat: line the zucchini in a single layer on a baking sheet and bake at 350 degrees F until warmed through, 5-10 minutes or rewarm at 20 second intervals in the microwave.
• Can I freeze zucchini?  I do not recommend freezing grilled zucchini because it is 94% water and will become mushy once thawed.

This grilled zucchini recipe can be served year-round because it can be made with squash in the winter AND you can use an indoor grill pan – so the better question might be, what not to serve with zucchini?
