I wanted something more exciting than steamed or sautéed, something that could stand up to the robust flavors of a grilled steak. This recipe, born from a bit of experimentation with fresh herbs from our patio pots, was an instant hit.

Ingredients

The magic of this recipe comes from using simple, fresh ingredients that are allowed to shine. Quality matters here, so opt for the freshest produce and herbs you can find.

• 4 tablespoons olive oil, divided: Using a good quality extra virgin olive oil will make a noticeable difference in the final flavor. We’ll use most of it for the flavorful drizzle and a small amount to coat the zucchini before it hits the grill.
• ¼ cup minced shallot: Shallots offer a delicate, sweet flavor that’s less overpowering than a regular onion. Their subtle profile melds beautifully with the garlic and herbs. If you don’t have a shallot, a small amount of finely minced red onion can be substituted.
• 2 cloves garlic, minced: Fresh garlic is non-negotiable here! The pungent, aromatic flavor is a cornerstone of this dish. Mince it finely to ensure it distributes evenly throughout the oil mixture.
• 2 tablespoons chopped fresh rosemary: Rosemary’s pine-like, woody aroma is a classic pairing for grilling. It infuses the oil with a robust, earthy flavor that complements the smokiness from the grill.
• 2 tablespoons chopped fresh parsley leaves: Fresh parsley adds a bright, clean, and slightly peppery note that balances the richness of the olive oil and the earthiness of the rosemary. Opt for flat-leaf (Italian) parsley for the best flavor.
• Kosher salt and freshly ground black pepper, to taste: Kosher salt has larger flakes that are ideal for seasoning and drawing out flavor. Freshly ground black pepper provides a hint of spice that you just can’t get from the pre-ground variety.
• 2 medium zucchini: Look for zucchini that are firm, with smooth, shiny skin and are about 6-8 inches in length. Larger zucchini tend to have more water and larger seeds, which can lead to a soggier result.
• 1 medium yellow squash: Also known as summer squash, this adds a lovely color and a slightly sweeter, nuttier flavor to the mix. The same rules for selection apply: choose firm, smaller squash for the best texture and flavor.

Instructions

Follow these steps carefully to achieve perfectly grilled, flavor-packed zucchini every single time. The key is high heat and quick cooking.

Step 1: Preheat Your Grill
Begin by preheating your grill to a steady medium-high heat, which is typically around 400-450°F (200-230°C). A hot grill is crucial for getting a good sear and those coveted grill marks without overcooking the vegetables. While it’s preheating, give the grates a good scrape with a grill brush to remove any old debris. This prevents sticking and ensures clean flavor.

Step 2: Prepare the Garlic Herb Drizzle
In a small bowl, combine 3 tablespoons of the olive oil, the minced shallot, minced garlic, chopped fresh rosemary, and chopped fresh parsley. Whisk everything together until it’s well combined. Season this mixture generously with kosher salt and freshly ground black pepper. Set this bowl aside. Allowing it to sit while you prep and grill the zucchini gives the flavors time to meld and infuse the oil, creating a much more potent and delicious sauce.

Step 3: Prep and Season the Zucchini
Take your zucchini and yellow squash and slice them on a diagonal into uniform 1/2-inch-thick pieces. Cutting on a diagonal (or “on the bias”) creates more surface area, which means more room for char and flavor. Place the slices in a large bowl or on a baking sheet. Drizzle them with the remaining 1 tablespoon of olive oil and use your hands to toss them gently, ensuring each slice is lightly coated. Season them simply with a bit more salt and pepper to taste.

Step 4: Grill to Perfection
Carefully arrange the seasoned zucchini and squash slices on the preheated grill in a single layer. It’s important not to overcrowd the grill; if you do, the vegetables will steam instead of char. It’s better to cook in two batches if necessary. Grill the slices for about 2 minutes per side. You’re looking for distinct char marks and for the zucchini to be just beginning to soften. It should still have a noticeable “bite” to it. This quick, high-heat cooking is the secret to avoiding mushy zucchini.

Step 5: Serve Immediately
As soon as the zucchini comes off the grill, transfer it to a serving platter. While it’s still hot, take the garlic herb oil mixture that you set aside earlier and drizzle it all over the grilled vegetables. The heat from the zucchini will gently cook the garlic and shallots and release an incredible aroma. Toss gently to coat and serve immediately for the best taste and texture.

How to Serve

This Grilled Garlic Herb Zucchini is a culinary chameleon. It’s fantastic on its own, but it also pairs beautifully with a wide variety of dishes and can be repurposed in creative ways.

• Grain Bowls: Use it as a component in a healthy grain bowl with quinoa, chickpeas, a dollop of hummus, and a squeeze of lemon juice.
• Sandwiches and Wraps: Layer the grilled slices into a vegetarian sandwich with goat cheese and roasted red peppers on ciabatta bread, or add them to a chicken wrap for extra flavor and texture.
• Pizza Topping: Chop it up and scatter it over a homemade or store-bought pizza crust with mozzarella and dollops of ricotta for a gourmet pizza night.

Additional Tips for Grilling Success

Master this recipe with these five expert tips that will guarantee perfect results every time.

1. Choose the Right Size Zucchini: Size matters. Opt for small to medium-sized zucchini and yellow squash. They are less watery and have fewer seeds than their oversized counterparts, which translates to a firmer, less soggy texture after grilling.
2. Don’t Salt Too Early: Salt draws moisture out of vegetables. If you salt your zucchini slices and let them sit for too long before grilling, they will release water and be more likely to steam and become mushy on the grill. For the best texture, salt them just before they go on the hot grates.
3. Achieve Perfect Grill Marks: The secret to those beautiful, dark, professional-looking grill marks is threefold: a hot grill, clean grates, and not moving the zucchini once you’ve placed it down. Let it sit for the full 2 minutes to allow the char to develop before you flip.
4. Embrace the Diagonal Cut: Slicing the zucchini on a 45-degree angle (on the bias) does more than just look pretty. It creates longer, wider slices with more surface area. This not only makes them easier to handle on the grill (less likely to fall through the grates) but also maximizes the area for charring and absorbing flavor.
5. Don’t Skimp on the Fresh Herbs: While dried herbs can work in a pinch, the vibrant, potent flavor of fresh rosemary and parsley is what truly makes this dish special. The fresh herbs in the final drizzle provide a burst of freshness that beautifully contrasts the smoky char of the zucchini.

Frequently Asked Questions (FAQ)

Here are answers to some common questions about making this Grilled Garlic Herb Zucchini.

1. Can I make this recipe without a grill?
Absolutely! You have two great options.

• Grill Pan: Use a cast-iron grill pan on your stovetop over medium-high heat. Follow the recipe exactly as written. You’ll still get beautiful grill marks and a similar texture.
• Oven Roasting: Preheat your oven to 425°F (220°C). Arrange the oil-coated and seasoned zucchini slices on a baking sheet in a single layer. Roast for 10-15 minutes, flipping halfway through, until tender and lightly browned. Once they are out of the oven, transfer to a platter and drizzle with the garlic herb oil mixture. The flavor will be slightly different (less smoky) but still delicious.

2. My zucchini always turns out soggy. What am I doing wrong?
Soggy zucchini is a common problem, but it’s easily avoidable. The main culprits are:

• Low Heat: Your grill or pan isn’t hot enough. You need high heat to sear the outside quickly.
• Overcrowding: Piling too many slices on the grill at once causes them to steam in their own moisture instead of grilling. Cook in batches if needed.
• Overcooking: Zucchini cooks very fast. Two minutes per side is usually plenty. Grill it until it’s just tender, not soft all the way through. It will continue to cook slightly from residual heat after you take it off.
• Slicing Too Thin: Slices thinner than 1/2-inch can fall apart and turn mushy very quickly.

3. Can I use different herbs in the recipe?
Yes, this recipe is a great template for experimentation! Feel free to substitute other hardy, grill-friendly herbs for the rosemary, such as fresh thyme or oregano. For the fresh parsley, you could substitute it with fresh dill for a different flavor profile, or add some fresh basil or mint to the drizzle right at the end for a bright, fresh kick. A pinch of red pepper flakes in the oil mixture would also be a great addition for those who like a little heat.

4. How should I store and reheat leftovers?
Store any leftover grilled zucchini in an airtight container in the refrigerator for up to 3-4 days. The texture will soften over time, so they are often best used cold or at room temperature in salads, sandwiches, or grain bowls. If you do wish to reheat them, do so gently in a skillet over medium heat or in a microwave for a very short time to avoid making them mushy.

5. Can I prepare any parts of this recipe in advance?
Yes, you can do some prep ahead of time to make assembly even quicker. The garlic herb oil mixture can be made up to a day in advance and stored in an airtight container in the refrigerator. Just be sure to bring it to room temperature before using so the olive oil re-liquefies. You can also wash and chop your herbs in advance. However, it’s best to wait to slice and salt the zucchini until just before you’re ready to grill to ensure the best possible texture.
