What You’ll Need
This spectacular platter is built around a selection of colorful vegetables that grill beautifully, tossed with a simple yet flavorful marinade of olive oil, garlic, and herbs. A touch of lemon juice at the end brightens everything up, making it a truly delightful experience.
Ingredient Notes
- Zucchini and Yellow Squash – These offer a tender bite and absorb the grill’s smoky essence wonderfully. Look for medium-sized squash that aren’t too watery.
- Bell Peppers – Red, yellow, and orange bell peppers provide sweetness and a beautiful visual appeal. Choose firm peppers with smooth skins.
- Red Onion – Grilling mellows the onion’s sharpness, bringing out a lovely sweetness. Wedges hold their shape well on the grill.
- Cherry Tomatoes – These burst with flavor when grilled, adding little pockets of juicy sweetness. Try to keep them on their stems for easier handling.
- Asparagus – Thick spears are best as they won’t fall through the grill grates. Snap off the woody ends for ease.
- Olive Oil – A good quality extra virgin olive oil forms the base of our simple marinade, helping the vegetables cook evenly and develop a nice sear.
- Garlic – Fresh garlic adds a foundational savory note that complements the vegetables perfectly.
- Dried Oregano – This classic herb lends an aromatic, slightly peppery flavor that’s a natural partner to grilled vegetables.
- Salt and Black Pepper – Essential for enhancing all the natural flavors of the vegetables.
- Lemon – A squeeze of fresh lemon juice right before serving adds a bright, zesty finish that awakens all the other tastes.
Add-ins and Substitutions
While this platter is perfectly wonderful as is, feel free to get a little creative! You can absolutely add other sturdy vegetables that grill well, such as eggplant slices, corn on the cob (cut into rounds), or even thick slices of halloumi cheese for a vegetarian protein boost. A sprinkle of fresh parsley or basil just before serving can also add another layer of freshness. When it comes to the marinade, a pinch of red pepper flakes can provide a gentle warmth if you like a little heat.

How to Make Gorgeous Rainbow Grilled Vegetable Platter
Making this Gorgeous Rainbow Grilled Vegetable Platter is a joyfully simple process that gets you from prep to plate in under an hour. The key is to prepare your vegetables so they grill evenly, then let the heat of the grill do its magic.
- Prepare the Vegetables: Start by washing and trimming all of your vegetables. Cut the zucchini and yellow squash into 1/2 inch thick rounds or lengthwise planks. Slice the bell peppers into 1-inch wide strips. Cut the red onion into 1-inch thick wedges, keeping the root end intact to help hold the layers together. Snap the woody ends off the asparagus spears. Keep the cherry tomatoes on their stems if possible, or threaded onto skewers if they seem loose.
- Make the Marinade: In a large bowl, whisk together the olive oil, minced garlic, dried oregano, salt, and black pepper.
- Toss and Marinate: Add all of the prepared vegetables (except the cherry tomatoes) to the bowl with the marinade. Gently toss everything together until each piece is well coated. For the cherry tomatoes, drizzle with a little olive oil, salt, and pepper directly in their own small bowl and toss lightly.
- Pro Tip: For the best flavor infusion, let the larger vegetables marinate for at least 15-20 minutes at room temperature while you preheat your grill. This allows the oil and seasonings to permeate the veggies.
- Preheat the Grill: Preheat your grill to medium-high heat. You want it nice and hot so the vegetables get lovely char marks without becoming mushy.
- Grill the Vegetables: Place the marinated vegetables onto the hot grill grates in a single layer. You may need to do this in batches depending on the size of your grill. Grill the zucchini, squash, bell peppers, and red onion for about 4-6 minutes per side, until tender and nicely charred. Add the asparagus and grill for about 3-5 minutes, flipping halfway through, until tender-crisp. Grill the cherry tomatoes for about 3-5 minutes, turning occasionally, until they are softened and just beginning to blister.
- Keep an eye on everything! Different vegetables cook at slightly different rates. The goal is tender-crisp with appealing char marks.
- Assemble the Platter: Once all the vegetables are grilled to perfection, arrange them artfully on a large platter. You can group them by color or mix them up for a vibrant mosaic effect.
- Finish and Serve: Squeeze fresh lemon juice generously over the entire platter just before serving.
Recipe Tips
- Don’t Overcrowd the Grill: Give your vegetables enough space on the grill to allow them to char properly rather than steam. This means you might need to cook in batches.
- Watch for Doneness: The vegetables should be tender enough to pierce easily with a fork but still have a slight bite. Avoid grilling them for too long, or they will become too soft.
- Uniform Sizing: Try to cut your vegetables into similarly sized pieces where possible. This helps them cook at a more consistent rate.
- Grill Marks are Key: A good char adds not only visual appeal but also a wonderful smoky flavor that makes this platter so special. Ensure your grill is hot enough before adding the vegetables.
FAQs
- Can I make this without a grill? Yes, you can achieve a similar result by roasting the vegetables in the oven on a baking sheet at 400°F (200°C) for about 20-25 minutes, or until tender and slightly caramelized. You can also use a grill pan on the stovetop.
- How should I store leftovers? Store any leftover grilled vegetables in an airtight container in the refrigerator for up to 3-4 days. They are delicious cold or gently reheated.
- Can I use different vegetables? Absolutely! This recipe is quite forgiving. Feel free to substitute or add other vegetables that grill well, such as corn, eggplant, or even hearty green beans. Just ensure they are cut to a size that will cook evenly.
- How do I prevent vegetables from sticking to the grill? Ensure your grill grates are clean and well-oiled before you start grilling. A grill brush can help with cleaning, and a paper towel dipped in oil (use tongs to hold it) can be used to quickly swipe the grates just before adding the food.
Serving Suggestions
This Gorgeous Rainbow Grilled Vegetable Platter is incredibly versatile. It makes a stunning side dish to grilled meats, chicken, or fish. It’s also a fantastic light lunch or a substantial vegetarian main course. Serve it alongside a fluffy bed of quinoa or couscous, or with a dollop of your favorite hummus or tzatziki. A simple side salad with a light vinaigrette would also be a lovely accompaniment.
Make This Recipe in Advance
You can prepare most of the vegetable prep and the marinade a day in advance. Wash, chop, and store the vegetables (except cherry tomatoes) in an airtight container in the refrigerator. Keep the olive oil, garlic, oregano, salt, and pepper mixture separate in a small jar. When you’re ready to cook, simply combine the vegetables and marinade, let them sit at room temperature for about 20 minutes, then grill as directed. The lemon juice should be added just before serving to keep its bright flavor.

Ingredients
¼ cup olive oil (or avocado oil/ coconut oil)
1 Tablespoon sea salt or kosher salt
1 Tablespoon freshly ground black pepper
8 ounces chimichurri sauce, optional
Grilling vegetable options:
8 carrots, medium size (rainbow or orange) or 16 baby carrots
1 large red onion Peel, cut lengthwise into 6 pieces, leaving root intact
4 zucchini or yellow squash, or combo of both, trim ends and quarter lengthwise
12 thick asparagus spears, woody ends trimmed
8 mini bell peppers cut in half and de-seeded (or 2 large bell pepper, de-seeded and cut into wide pieces)
1 bunch broccoli florets or broccolini ends trimmed
20 cherry tomatoes, on the vine
1 head baby bok choy cut in half or quarters lengthwise, leaving stem intact
6 garlic cloves, peeled
Instructions
Preheat your grill to medium-high direct heat, between 380F and 400F.
Lightly oil the grill grates, as well as a grill basket if you plan to use one.
Wash, trim, and cut your selected vegetables as directed in the ingredients list.
If you are using chimichurri sauce, prepare it now and set it aside in a small serving bowl.
Arrange all of your prepared veggies on a large baking sheet, drizzle them with oil, and toss gently to coat before seasoning with salt and pepper.
Begin grilling by placing the vegetables that require the longest cooking times on the grill first. To prevent long, slender vegetables from falling through, place them perpendicular to the grill grates.
Grill the vegetables in batches based on cooking times, turning once halfway through using tongs or a spatula until they are tender and beautifully charred.
– Long-cooking veggies (carrots, onions, broccoli, garlic): Grill for about 4 minutes per side.
– Medium-cooking veggies (squash, zucchini, mini peppers, asparagus): Grill for about 3 minutes per side.
– Quick-cooking veggies (cherry tomatoes, baby bok choy): Grill for 1 to 2 minutes per side.
Transfer the grilled vegetables to a large serving platter as they finish cooking.
Serve the colorful platter warm or at room temperature, paired with the chimichurri sauce.
