Grilled Zucchini and Squash

At Asador.mx, we believe that a great asado is not just about the meat — it's about everything that comes off the grill. Grilled zucchini and squash are two of our absolute favorite vegetables to throw on the parrilla. They char beautifully, absorb smoky flavors like a dream, and require almost zero effort. Whether you're a first-time griller or a seasoned asador looking to round out your spread, this recipe is your new go-to side dish.

Summer squash and zucchini are mild, versatile vegetables that transform completely when exposed to direct heat. The high temperature of the grill caramelizes their natural sugars, creates gorgeous char lines, and concentrates their flavor in a way that no other cooking method can replicate. Paired with garlic, oregano, smoked paprika, and a squeeze of lemon, these grilled vegetables taste like they came straight out of a Buenos Aires parrilla restaurant.

Why Grill Zucchini and Squash the Argentine Way?

Argentine grilling culture has always honored vegetables as much as proteins. In a traditional asado, vegetables are often placed around the edges of the parrilla, soaking up heat and smoke while the main cuts cook. This slow, smoky approach yields vegetables with incredible depth of flavor. Our version takes that same philosophy and applies it to zucchini and yellow squash — two vegetables that are widely available, affordable, and incredibly easy to work with.

The key to Argentine-style grilled vegetables lies in the seasoning. We keep it simple but intentional: olive oil to carry flavor and prevent sticking, garlic for aromatic depth, dried oregano as a nod to classic chimichurri herb profiles, and smoked paprika to enhance the charred, smoky notes from the grill. A finishing squeeze of lemon and a handful of fresh parsley bring everything together with brightness and color.

Tips for Perfect Grill Marks and Texture

Getting the perfect char on zucchini and squash is all about preparation and patience. First, always dry your vegetable slices before seasoning them. Excess moisture creates steam, which prevents browning and leads to soggy results. A quick pat with a paper towel makes a significant difference in the final texture.

Second, resist the urge to move the vegetables once they hit the grill. Let them sit undisturbed for at least 4 minutes before flipping. This allows the Maillard reaction to work its magic, creating those beautiful caramelized grill marks and a slightly crisp exterior. If the slices stick when you try to flip them, they simply need more time — properly grilled vegetables release naturally from clean, oiled grates.

Third, slice your vegetables lengthwise rather than into rounds. Lengthwise planks are easier to handle on the grill, less likely to fall through the grates, and provide a larger surface area for char development. Aim for slices about 1/4-inch thick — thin enough to cook through quickly, but thick enough to hold their shape and develop texture.

Choosing and Storing Your Zucchini and Squash

For the best grilling results, choose small to medium zucchini and yellow squash. Larger vegetables tend to have more seeds and a higher water content, which can lead to mushier results on the grill. Look for firm, glossy vegetables with no soft spots or blemishes. Fresh is always best, but if you need to store them before grilling, keep them unwashed in the refrigerator crisper drawer for up to five days.

Using both green zucchini and yellow squash together is more than just aesthetic — their slightly different flavor profiles and textures complement each other beautifully on the plate. The zucchini tends to be slightly firmer and more neutral in flavor, while yellow squash has a subtle sweetness that caramelizes wonderfully over high heat. Together, they create a visually stunning and delicious dish.

Serving Suggestions and Pairings for the Asado Table

Grilled zucchini and squash are one of the most versatile side dishes you can serve at an Argentine BBQ. They pair exceptionally well with classic asado cuts like entraña (skirt steak), vacío (flank steak), or costillas (beef ribs). The lightness and acidity of the lemon-dressed vegetables cut through the richness of the grilled meat, creating a perfectly balanced plate.

You can also drizzle the finished vegetables with a spoonful of classic green chimichurri for an extra layer of herbaceous, garlicky flavor. If you're hosting a mixed crowd that includes vegetarians, these grilled vegetables can be served over a bed of quinoa or tucked into warm flatbread with a dollop of yogurt sauce for a satisfying main course. Leftovers — if you have any — are fantastic chopped into pasta or layered into a breakfast frittata the next morning.

No matter how you serve them, grilled zucchini and squash are proof that the simplest ingredients, treated with care and cooked over live fire, always deliver the most memorable flavors. Fire up your grill, season generously, and let the parrilla do the rest. Buen provecho!
