Step‑by‑Step Instructions for Grilled Zucchini Squash Skewers
Step 1: Prep Vegetables
Begin by washing the zucchini and yellow squash thoroughly. Using a mandoline or a sharp chef’s knife, cut the squash into ribbons that are approximately 1/8 inch thick. This uniformity will ensure even cooking. Aim for a mix of both zucchini and yellow squash to enhance the visual appeal of your Grilled Zucchini Squash Skewers.
Step 2: Assemble Skewers
Next, take wooden or metal skewers and start threading the vegetable ribbons onto them. Interspersing some colorful bell peppers or mushrooms can add variety and flavor to your skewers. Make sure to leave a little space between the pieces for better grilling; this will help create those perfect char marks.
Step 3: Season
Once your skewers are assembled, brush them generously with olive oil to promote that smoky flavor while grilling. Sprinkle them with salt and pepper to taste, ensuring each side is well-seasoned. Finally, add a generous amount of grated parmesan cheese on top, allowing it to adhere to the oiled veggies for that extra flavor boost during grilling.
Step 4: Grill
Preheat your grill to medium-high heat, around 400°F (200°C). Place the skewers on the grill, allowing them to cook for approximately 12 minutes. Turn the skewers occasionally to achieve a nice char on all sides. Look for that beautiful golden color and tenderness in the veggies, indicating they are ready to come off the grill.
Step 5: Serve
Once the Grilled Zucchini Squash Skewers are perfectly charred and tender, remove them from the grill. Serve them immediately as a vibrant side dish. For an added touch, you can sprinkle more fresh parmesan or chopped herbs on top, making these skewers not only delicious but a feast for the eyes!

Make Ahead Options
These Grilled Zucchini Squash Skewers are a fantastic option for meal prep, allowing you to enjoy delicious grilled veggies with minimal effort. You can prep the zucchini and yellow squash ribbons and assemble the skewers up to 24 hours in advance by refrigerating them in an airtight container. Just be sure to brush them with olive oil and season them right before grilling to maintain their vibrant flavor and texture. When you’re ready to serve, simply preheat your grill and cook the prepared skewers for about 12 minutes, turning occasionally until charred and tender. This simple prep not only saves time but ensures your skewers are just as delightful as if you made them fresh!

Grilled Zucchini Squash Skewers Recipe FAQs
What type of zucchini should I choose?
Absolutely! When selecting zucchinis, look for ones that are firm, smooth, and free from dark spots or soft spots. Smaller zucchinis tend to be sweeter and more tender, so go for those if you can. Also, consider combining both zucchini and yellow squash for a colorful presentation.
How should I store leftover Grilled Zucchini Squash Skewers?
Leftover skewers can be stored in an airtight container in your refrigerator for up to 2 days. Enjoy them cold as a refreshing snack or quickly reheat by placing them on the grill for a few minutes or in the oven at 350°F (175°C) until warmed through.
Can I freeze Grilled Zucchini Squash Skewers?
Very! To freeze the skewers, first lay them in a single layer on a baking sheet and place them in the freezer until they are frozen solid, which usually takes about 2-3 hours. Once frozen, transfer them to a freezer-safe bag, removing as much air as possible. They can be kept for up to 3 months. When ready to use, thaw them in the refrigerator overnight, and grill or bake at 350°F (175°C) for about 10 minutes until heated.
What if my skewers aren’t cooking evenly?
If you find that your skewers aren’t cooking uniformly, it may be because the pieces are cut of different sizes. Take care to cut your zucchini and yellow squash into ribbons that are all approximately 1/8 inch thick. Additionally, don’t overcrowd the skewers; leaving space between the pieces allows the heat to circulate and char evenly, resulting in those desirable grill marks and tenderness.
Are these skewers safe for gluten-free diets?

Just be mindful with any sauces or additional seasonings you might want to add—always check labels to ensure there’s no hidden gluten.
Can my pets eat cooked zucchini?
Yes, sometimes! Cooked zucchini can be a healthy treat for pets, but moderation is key. Always ensure that it’s plain—avoid any seasoning or cheese. Additionally, it’s wise to consult with your vet to ensure it’s suitable for your pet’s specific dietary needs.
