Start by removing the kernels from fresh corn cobs. Using a sharp knife, carefully slice the kernels off the cob, holding the ear upright on a cutting board. If you’re using frozen corn, make sure it's fully thawed and drained to avoid excess moisture in your salad.
In a large mixing bowl, add the fresh corn kernels, diced red onion, halved cherry tomatoes, and chopped cilantro. These fresh ingredients form the colorful base of the salad.
In a small bowl, whisk together the olive oil, chili powder, and freshly squeezed lime juice. This simple dressing adds a tangy and slightly spicy flavor that complements the sweetness of the corn perfectly.
Pour the dressing over the corn and vegetable mixture. Toss everything gently but thoroughly to ensure each bite is packed with flavor. Season with salt and pepper to taste.
Finally, sprinkle the crumbled cotija cheese over the top of the salad. The salty, creamy cheese adds richness and a delightful texture contrast.
Serve the Mexican Street Corn Salad immediately or chill it for 20-30 minutes to let the flavors meld together. It’s perfect as a side dish or served alongside grilled meats, tacos, or as a topping for nachos.
