Step‑by‑Step Instructions for Grilled Zucchini Squash Skewers
Step 1: Preheat the Grill
Start by preheating your grill to medium heat, approximately 350°F to 400°F. This temperature range will ensure those delicious char marks and even cooking on the Grilled Zucchini Squash Skewers. While your grill warms up, gather your skewer materials and prep your veggies, ensuring everything is ready for a seamless grilling experience.
Step 2: Slice the Vegetables
Using a mandoline slicer or a sharp chef’s knife, carefully cut the zucchini and yellow squash into 1/8 inch thick ribbons. Aim for uniform slices to help with even cooking and crispness. The vibrant ribbons will not only look stunning on the skewers but will also absorb the delicious flavors as they grill.
Step 3: Prepare the Marinade
In a mixing bowl, toss the sliced zucchini and yellow squash ribbons with olive oil, freshly squeezed lemon juice, and salt until they are evenly coated. This marinade will enhance the flavor of your Grilled Zucchini Squash Skewers and create that delightful char. Allow them to marinate for about 5 minutes to soak in the goodness while you prepare the skewers.
Step 4: Assemble the Skewers
Thread the marinated vegetable ribbons onto skewers, alternating with any additional vegetables like bell peppers or mushrooms if desired. Ensure to leave a little space between each ribbon to allow for even grilling and to prevent sticking. Fill each skewer to your preference, creating a vibrant medley that will impress everyone at your gathering.
Step 5: Grill the Skewers
Place the assembled skewers on the preheated grill and cook for about 12 minutes, turning them occasionally to achieve even char and tenderness. Look for visual cues like tender veggies and appealing grill marks to ensure they’re cooked to perfection. This grilling step enhances the flavors and creates a smoky taste that elevates your Grilled Zucchini Squash Skewers.
Step 6: Add Cheese and Herbs
Once the skewers are beautifully grilled, sprinkle freshly grated parmesan cheese over them while they’re still warm, allowing it to melt slightly. For an extra touch of flavor, consider garnishing with your favorite fresh herbs such as basil, cilantro, or parsley. This elevates the presentation and adds a burst of freshness to your dish just before serving.

Grilled Zucchini Squash Skewers Recipe FAQs
What type of zucchini should I use for the skewers?
Absolutely! Look for fresh, firm zucchini that feels heavy for its size and has a vibrant color. Avoid those with dark spots all over, as they’re likely overripe. Also, if choosing yellow squash, pick ones that are similar in size to your zucchini for even cooking.
How should I store leftover skewers?
Very! After enjoying your delicious Grilled Zucchini Squash Skewers, allow them to cool and then place them in an airtight container. They can be stored in the fridge for up to 2 days. When ready to enjoy again, I recommend reheating them in a hot skillet to regain their beloved texture.
Can I freeze the skewers?
Certainly! To freeze your grilled skewers, allow them to cool completely first. Then, wrap the skewers tightly in plastic wrap, ensuring no air is trapped, and place them in a freezer bag. They can be stored in the freezer for up to 3 months. When you’re ready, thaw them in the fridge overnight before reheating on the grill or in a skillet.
What should I do if my zucchini is soggy?
Great question! If your zucchini turns out soggy, it might be due to overcooking or using very ripe squash. To help, always aim for uniform thickness while slicing—around 1/8 inch is ideal. For future grilling, consider letting your zucchini sit with salt for about 10-15 minutes before cooking. This can help draw out excess moisture, giving you that perfect, tender yet crisp texture.
Are these skewers suitable for gluten-free diets?
Absolutely! These Grilled Zucchini Squash Skewers are a fantastic gluten-free option. They contain no gluten ingredients, making them perfect for anyone with dietary restrictions. Plus, they can be paired with gluten-free grilled proteins like chicken or shrimp for a complete meal!
Can I use wooden skewers, and do they need special treatment?
Yes, you can use wooden skewers! However, it’s essential to soak them in water for about 30-60 minutes before grilling. This prevents them from burning on the grill. After soaking, they’ll hold up nicely to the heat while showcasing your gorgeous vegetable medley!
