For the Grilled Zucchini:

  • 2 tablespoons olive oil
  • Salt and pepper

For the Olive Pesto:

  • 1 cup green olives
  • 1 small onion, grilled

  • ½ cup olive oil

The Recipe How-To

Preparing the ingredients

Step 1: Begin by preheating your grill to medium-high heat or warming a skillet over medium heat.

Step 2: While the grill or pan is heating up, slice the zucchini lengthwise into pieces that are about an inch thick (1-2 zucchinis depending on size should be enough).

Step 3: Season the zucchini generously with salt and pepper. This will help bring out its natural flavors and help it caramelize beautifully on the grill or in the pan.

Grilling the Zucchini

Step 4: When your grill or skillet is hot, brush some olive oil onto the zucchini slices.

Step 5: Place them onto the grill or skillet and cook for about 3-4 minutes per side, until they’re nicely charred and softened.

Step 6: For added flavor, drizzle some balsamic vinegar onto the grilled zucchini before taking it off the grill.

Assembling the Sandwich

Step 7: To make a basic zucchini sandwich, start by slicing a piece of bread and layering it with grilled zucchini, lettuce, and sliced tomatoes.

Step 8: Add a dollop of mustard for extra tanginess.

Step 9: Top it off with another slice of bread and enjoy!

Substitutions and Variations

Now, some of you might be thinking, “I’m not really into zucchini or the classic caprese sandwich.” Well, don’t worry my friends, because there are plenty of substitutions and variations to make this grilled zucchini sandwich recipe your own.

For a twist on the classic caprese sandwich, try using roasted red bell peppers instead of tomatoes. The sweetness of the peppers paired with the creamy goat cheese and zesty green olive pesto will have your taste buds dancing with joy.

If you’re feeling adventurous and want to add some spicy flavors to the mix, try making a banh mi-style sandwich by adding pickled carrots, daikon radish and a spicy sriracha mayo.

Or, switch things up completely and add some sliced avocado to your spinach or arugula base for a creamy addition. If you’re looking for more protein, try adding grilled chicken or tofu.

Another alternative is to use thinly sliced eggplant instead of the zucchini. This will create grilled eggplant zucchini panini sandwiches that are great for vegetable lovers who want something different.

For those who prefer a less cheesy option, ditch the goat cheese and go for ricotta instead. Alongside roasted summer squash, this variation provides a refreshing twist on the original grilled zucchini sandwich recipe.

No matter which substitution or variation you choose, don’t forget to season your vegetables well and top off each bite with balsamic vinegar or a drizzle of olive oil.

Serving and Pairing

Ah, the glorious moment has arrived, the moment when we finally get to savor those scrumptious grilled zucchini sandwiches that we’ve just spent our time and effort preparing. But what should we pair with them in order to make the experience even more exquisite? While some might suggest downing one of these with a cup of coffee or tea, for others a glass of chilled white wine will do the trick.

If you’re looking for a light and refreshing pairing, I strongly recommend serving your grilled zucchini sandwiches with a salad made up of lettuce and cherry tomatoes. The mustard vinaigrette dressing of the salad perfectly balances the creamy taste of the cheese in the sandwiches while the acidity of the tomatoes cuts through any potential heaviness from the bread.

However, if you’re feeling more indulgent or simply don’t like salads all that much, the grilled zucchini sandwich pairs wonderfully with a side of homemade potato chips. The crispy texture and subtle saltiness of the chips contrasts beautifully with the softness and mellow flavor of the sandwich.

Lastly, if you’re having company over or want to elevate your everyday meal, consider adding a Caprese salad made with sliced fresh mozzarella, tomatoes, and basil, along with a drizzle of balsamic vinegar. In this way, you’ll create a cohesive Italian-inspired menu that will make you feel as if you were dining al fresco at a picturesque trattoria in Rome.

Whatever you choose to serve alongside this delicious grilled zucchini sandwich recipe, just remember that simple yet quality ingredients are always key to achieve culinary greatness.

I’m not sure if Ernest Hemingway is the best author for writing about cooking, but I’ll give it a try!

It’s important to note that although this grilled zucchini sandwich recipe is best enjoyed right after grilling, it can still be prepared in advance or reheated for later. Here are some tips for making and storing the sandwich:

Make-ahead: If you’re planning on making the sandwiches ahead of time, you can grill the zucchini and store it in an airtight container in the refrigerator for up to three days. You can also slice the bread and assemble the sandwiches without toasting them, then wrap them tightly in plastic wrap and refrigerate until ready to use. This will save you time when you’re ready to cook.

Storing: If you have any leftover sandwiches, store them in an airtight container in the refrigerator for up to two days. Note that the bread may become slightly soggy with storage, so it won’t taste quite as good as when freshly made.

Reheating: To reheat the sandwich, preheat your oven to 350°F (180°C), place the sandwich on a baking sheet, and bake it in the oven for around 10 minutes until heated through. You can also reheat it quickly in a skillet over medium heat if you prefer. Just make sure that the cheese has melted properly before serving.

Remember that while reheating is an option, nothing beats a hot and fresh grilled zucchini sandwich straight off the grill. So, if possible, plan ahead and prepare only as much as you can serve immediately!

To make the best grilled zucchini sandwich, there are a few tips that you need to keep in mind. These tips will help you get the perfect texture and flavor in your sandwiches. Here are some of my expert tips for making the perfect grilled zucchini sandwich:

First, make sure to season your zucchini slices generously with salt and pepper before grilling. This will enhance their flavor and also help to draw out any excess moisture, making them less watery.

Next, preheat your grill or skillet to medium high heat before adding the zucchini slices. This will help to ensure that they cook evenly and quickly.

When grilling the zucchini, be sure not to overcook it. You want it to be slightly charred on the outside but still slightly firm on the inside. Overcooked zucchini can become mushy and unappetizing.

If you’re using cheese in your sandwich, like a slice of roasted zucchini goat cheese or fresh mozzarella in a zucchini caprese sandwich, add it to the sandwich when the zucchini is warm so it can melt perfectly.

Try pairing your grilled zucchini with other vegetables like bell peppers or summer squash for a delicious, colorful vegetable medley in your sandwich. You can even make grilled vegetable panini with eggplant for an Italian-inspired sandwich.

Finally, use good quality bread like sourdough or ciabatta for your sandwich. It should be sturdy enough to hold all of the delicious ingredients without falling apart.

Remember these helpful tips and you’ll have perfectly grilled zucchini sandwiches every time!

Should Zucchini be salted before grilling?

If you’re wondering whether or not to salt your zucchini before grilling it, the answer is that it’s not a requirement, but it can definitely enhance its flavor. Adding salt to zucchini draws out some of its liquid, making it firmer and avoiding the mushy texture that can occur when using steamed vegetables. So, if you want a more delectable grilled zucchini, salting it before cooking is a fantastic option to consider.

Can you eat zucchini raw on a sandwich?

Did you know that raw zucchini can be eaten? Although it has a gentle taste on its own, when combined with other ingredients, it can create various flavors. By slicing it thinly or grating it, it can be used in a variety of dishes such as salads, sandwiches, or even as a decorative topping.

Grilled Zucchini Sandwich

Grilled Zucchini Sandwich Recipe

I put this together one night after work. I’m trying a new thing where I only eat meat one meal a day, and I’d already eaten chicken for lunch. When I got home from work my dad had made steak, so instead I used the grilled zucchini side dish and made a sandwich. The zucchini has the texture of a meat like sliced turkey or ham, so it feels like you’re not stuck with a pile of veggies between bread. The hummus is a nice protien to keep your meal well rounded. The cook time is for the zucchini
