The Best Grilled Squash and Zucchini with Dijon Marinade

Why This Grilled Squash and Zucchini Recipe Works

This grilled squash and zucchini recipe stands out because of its simple yet flavorful dijon marinade. The combination of Dijon mustard, garlic, and herbs creates an irresistible tangy essence that elevates the natural sweetness of the vegetables. Plus, grilling brings out a smoky flavor and delightful char, making every bite a treat.

Perfecting the Dijon Marinade for Vegetables

The dijon marinade is the star of this dish. It beautifully balances the rich olive oil with a hint of spice and herb. Whisking together ingredients like minced garlic and thyme allows the flavors to meld, creating a sauce that coats the veggies perfectly. This marinade not only enhances the taste but also helps tenderize the squash and zucchini.

Ingredients for Grilled Zucchini and Squash

Key Vegetable Choices

For this recipe, choose 2 medium zucchini and 2 medium yellow squash. Both varieties have a mild flavor and a tender texture that grill beautifully. Keeping the skin on adds nutrients and helps maintain their structure while cooking.

Marinade Components and Substitutions

Gather the following ingredients for the marinade: ¼ cup extra-virgin olive oil, 1 tablespoon Dijon mustard, 1 teaspoon minced garlic, 1 teaspoon dried thyme, ½ teaspoon kosher salt, ¼ teaspoon black pepper, and ¼ teaspoon crushed red pepper flakes. If you have dietary preferences, you can substitute brown mustard for Dijon or use fresh thyme instead of dried.

How to Prepare Zucchini and Squash for Grilling

Optimal Cutting Techniques for the Grill

Slice the zucchini and yellow squash lengthwise into pieces that are ¼ to ½ inch thick. This size ensures even cooking and makes flipping them on the grill easier. While rounds are an option, they often require a grill basket to prevent slipping through the grates.

Marinating for Maximum Flavor

After cutting your vegetables, place them in a large bowl. Pour the prepared marinade over the sliced veggies and toss gently, ensuring they’re all coated. Let them marinate for about 15 minutes while the grill heats up, allowing the flavors to penetrate the squash and zucchini.

Grilling Your Zucchini and Squash to Perfection

Grill Preparation and Temperature

Preheat your gas or charcoal grill to medium heat, about 400-450°F. This temperature is ideal for achieving a great char without steaming the vegetables. If you’re using a grill pan, preheat it for 8-10 minutes for the best results.

Grilling Technique for Even Cooking

Place the marinated vegetable slices on the grill in a single layer, positioning them perpendicular to the grates. This technique helps prevent them from slipping through. Grill for 2 to 3 minutes per side while keeping the lid open. This allows for great charring and prevents steaming, ensuring each slice remains crisp and flavorful.

Delicious Variations and Serving Suggestions

Flavor Twists: Blackened, Italian, Chimichurri, and Moroccan

Experiment with different flavors by trying variations. For a blackened twist, substitute Cajun seasoning for the thyme. If you’re craving Italian, use an Italian seasoning blend and top with grated parmesan. You can also use homemade chimichurri as the marinade or incorporate harissa for a Moroccan flair. Each variation brings a unique taste to this versatile dish.

Serving Ideas and Pairings

Serve your grilled squash and zucchini with fresh herbs, a drizzle of lemon juice, or even crumbled feta for an added punch. Pair them with roasted red pepper crema or honey mustard for an extra touch of flavor. They make a perfect side dish alongside grilled meats or as a stand-alone vegetarian delight.

Expert Tips for Grilling Squash and Zucchini

Avoiding Common Grilling Mistakes

To avoid common mistakes, ensure you cut the vegetables evenly and do not close the grill lid while cooking. This prevents them from steaming and helps achieve the perfect char. Remember to save the excess marinade to drizzle over the grilled veggies for added flavor.

Storage and Reheating Leftovers

Store any leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, place them in a pan over low heat or use a microwave for quick warming without losing texture.
