What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without the fuss. The zucchini and yellow squash give you that fresh summer vibe, while the herb butter brings everything together with richness and brightness. Most of these are pantry staples or easy to find at your local market or farmer’s stand.

• Zucchini: 2 medium-sized, sliced lengthwise into ¼-inch thick strips (look for firm, vibrant green zucchini for the best texture)
• Yellow squash: 2 medium, sliced the same way as zucchini (adds a nice color contrast and slight sweetness)
• Unsalted butter: 4 tablespoons, softened (I recommend Kerrygold for a creamy, rich finish)
• Fresh parsley: 2 tablespoons, finely chopped (brightens the butter with herbal freshness)
• Garlic: 2 cloves, minced (use fresh for the best punch)
• Lemon zest: From 1 lemon (adds a subtle citrus lift that cuts through the butter’s richness)
• Salt: ½ teaspoon, or to taste (sea salt preferred)
• Black pepper: Freshly ground, about ¼ teaspoon
• Olive oil: 1 tablespoon, for brushing the veggies before grilling (extra virgin for flavor)

Optional:

• Fresh thyme or basil instead of parsley for a different herb profile
• Pinch of red pepper flakes if you like a little heat
• Use dairy-free butter or coconut oil if you need a vegan alternative

In summer, swapping fresh herbs based on what’s in your garden is one of my favorite ways to keep this recipe feeling new. I also love grabbing zucchini and squash from local farmer’s markets where they’re picked at peak freshness, which really makes a difference in texture and flavor.

Equipment Needed

For this grilled zucchini and squash medley, you don’t need much, but having the right tools makes a difference.

• Grill: Charcoal or gas grill works great. I prefer charcoal for that authentic smoky flavor, but gas is perfect for quick heat control.
• Grill basket or grill pan: Optional but helpful for keeping smaller slices from falling through the grates.
• Mixing bowl: To toss the veggies with olive oil and seasoning before grilling.
• Small bowl and fork: For mixing the herb butter ingredients together.
• Tongs: For flipping the zucchini and squash on the grill without piercing them.
• Sharp knife and cutting board: For slicing the vegetables evenly.

If you don’t have a grill, a grill pan can work indoors, though you won’t get quite the same smoky char. I’ve used budget-friendly cast iron pans that heat evenly and give you those lovely grill marks. Just make sure it’s well-seasoned to prevent sticking. Also, a handheld zester or microplane is a game-changer for getting that fresh lemon zest in the herb butter.

Preparation Method

1. Prepare the herb butter: In a small bowl, combine 4 tablespoons of softened unsalted butter, 2 tablespoons finely chopped fresh parsley, 2 minced garlic cloves, and the zest of one lemon. Add ½ teaspoon salt and ¼ teaspoon freshly ground black pepper. Mix well with a fork until everything is evenly distributed. Set aside to let the flavors meld while you prep the veggies. (This usually takes about 5 minutes.)
2. Slice the zucchini and yellow squash: Wash and dry 2 medium zucchinis and 2 medium yellow squashes. Slice them lengthwise into ¼-inch thick strips. Try to keep the slices uniform—this helps them cook evenly on the grill. (Takes around 5-7 minutes.)
3. Toss veggies with olive oil and seasoning: Place the sliced zucchini and squash in a large mixing bowl. Drizzle with 1 tablespoon of extra virgin olive oil, then sprinkle with a pinch of salt and pepper. Toss gently to coat all pieces evenly without bruising the slices. (About 2 minutes.)
4. Preheat your grill: Get your grill hot—medium-high heat is perfect, roughly 400°F (200°C). If using charcoal, wait until the coals are glowing red with a layer of white ash. Oil the grill grates lightly to prevent sticking.
5. Grill the veggies: Arrange the zucchini and squash strips directly on the grill grates or in a grill basket. Cook for 3-4 minutes per side, flipping once gently with tongs. You’re looking for tender slices with nice grill marks and a slight char but not burnt. If the veggies start to blacken too fast, move them to a cooler spot on the grill. (Total grilling time about 8-10 minutes.)
6. Finishing touch: Remove the grilled veggies from the heat and immediately brush them generously with the prepared herb butter. The residual heat will melt the butter, coating each piece with flavor. Let them rest for a few minutes before serving so the butter can soak in.

If you notice your squash is releasing a lot of water while grilling, don’t worry—that’s normal. The key is to keep the heat high enough so it evaporates quickly, preventing sogginess. Also, flipping only once helps maintain the integrity of the slices. Over-flipping can break them apart.

Cooking Tips & Techniques

Getting the perfect grilled zucchini and squash medley is all about balance and timing. Here are some things I’ve learned the hard way (and the easy way):

• Don’t slice too thin: Thin slices will fall apart on the grill or turn mushy. Around ¼-inch thickness hits the sweet spot for tenderness and hold.
• Oil the veggies, not the grill: Brushing the veggies directly with olive oil helps prevent sticking and gives a nice sear without flare-ups.
• Use fresh herbs in the butter: I once tried dried herbs in the butter, and it fell flat—fresh does make a noticeable difference.
• Mind your grill heat: Medium-high heat gives those beautiful grill marks without incinerating your veggies. If needed, create a two-zone fire so you can move veggies around if they char too fast.
• Don’t overcrowd the grill: Give each slice some space. Crowding traps steam and leads to soggy veggies.
• Multitask efficiently: While the veggies grill, I usually prepare a quick salad or set the table. The herb butter can be made ahead to save time.

One time, I left the squash on the grill too long, and it turned almost mushy—lesson learned! Now, I’m super vigilant about timing and always test a slice early. The first bite should be tender but still with a little bite. Also, warming the herb butter slightly before brushing helps it melt faster and soak in better.

Variations & Adaptations

This grilled zucchini and squash medley is pretty versatile. Here are some ways to switch it up depending on your mood, dietary needs, or what’s in season:

• Spicy Herb Butter: Add a pinch of crushed red pepper flakes or a dash of smoked paprika to the herb butter for a subtle kick.
• Vegan-Friendly: Substitute the butter with a plant-based spread or coconut oil mixed with herbs and lemon zest.
• Different Herbs: Swap parsley for fresh basil, thyme, or mint for a new flavor profile. Mint gives a cool contrast that’s lovely on hot days.
• Grill with other veggies: Add sliced bell peppers or asparagus to the medley for more color and texture variety.
• Oven-Roasted Version: If you can’t grill, roast the veggies in a 425°F (220°C) oven on a foil-lined pan for 15-20 minutes, flipping halfway.

Personally, I’ve tried layering the grilled medley over a bed of couscous or quinoa, drizzling with a little balsamic glaze for a quick vegetarian main that’s still light and satisfying. It’s also a great way to use up herbs from the garden, especially when you’ve got an abundance of basil or thyme.

Serving & Storage Suggestions

Serve this grilled zucchini and squash medley warm or at room temperature. The herb butter’s richness shines best when the veggies are still slightly warm, but they’re also great the next day cold in a salad or sandwich.

This medley pairs beautifully with grilled proteins like chicken, steak, or fish. I often serve it alongside grilled bourbon glazed salmon or with a hearty burger for a balanced summer meal. A squeeze of fresh lemon juice over the top just before serving adds an extra pop of brightness.

To store, place the grilled veggies in an airtight container and refrigerate for up to 3 days. For best flavor, reheat gently in a skillet or at low oven temperature to avoid drying out. The herb butter flavor actually deepens overnight, making leftovers surprisingly good.
