This Mexican Street Corn Salad takes everything you love about classic elote — the creamy mayo coating, tangy cotija cheese, smoky chili powder, and bright lime — and transforms it into a scoopable, shareable salad ready in under 30 minutes. Charred corn kernels are tossed in a bold, spiced sour cream and mayo dressing, finished with jalapeño, red onion, fresh cilantro, and a generous crumble of cotija for a side dish that disappears from the table every single time.
If using fresh corn, husk the ears and slice the kernels off each cob using a sharp knife, cutting downward close to the cob. If using frozen or canned corn, measure out 4 cups and pat the kernels thoroughly dry with paper towels to remove excess moisture.
Heat a cast iron skillet over high heat for 2 to 3 minutes until very hot, then add the avocado oil and corn in a single layer. Let the corn sit undisturbed for 2 to 3 minutes to char, then stir and cook another 2 to 3 minutes until about 30 to 40 percent of the kernels have dark char spots. Season with salt and pepper, then transfer to a large mixing bowl to cool for 5 to 7 minutes.
While the corn cools, finely dice the jalapeño (remove seeds for mild) and red onion, mince the garlic, chop the cilantro, and zest and juice the limes.
In a small bowl, stir together the mayonnaise, sour cream, minced garlic, lime juice, lime zest, chili powder, smoked paprika, cumin, and cayenne until smooth and fully combined. Taste and adjust seasoning as needed.
Pour the dressing over the cooled corn, then add the jalapeño, red onion, 3/4 cup of the crumbled cotija cheese, and the chopped cilantro. Gently fold everything together until evenly coated.
Taste and adjust salt, pepper, or lime juice as needed, then transfer to a serving bowl. Top with the reserved 1/4 cup cotija, a pinch of chili powder and smoked paprika, fresh cilantro leaves, and lime wedges on the side.
Notes
Dry the corn well: Whether using fresh, frozen, or canned corn, patting the kernels thoroughly dry is the most important step for achieving a good char instead of steaming.
Preheat your pan properly: The skillet must be very hot before adding the corn. A lukewarm pan will steam the kernels and prevent charring.
Don't overcrowd the skillet: For a large batch, char the corn in two separate batches to maintain high heat and achieve even charring.
Cool before dressing: Always let the charred corn cool for at least 5 to 7 minutes before adding the mayo and sour cream dressing, or the heat will cause it to become watery.
Cotija substitute: If cotija is unavailable, crumbled feta cheese is the best substitute. Queso fresco also works well.
Make it lighter: Swap the mayonnaise for plain Greek yogurt to reduce calories while keeping the dressing creamy.
Make ahead: The full salad can be made up to 24 hours in advance and stored covered in the refrigerator. Add the final cotija topping and a fresh squeeze of lime just before serving.
Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Do not freeze, as the creamy dressing will separate upon thawing.
Grilled version: For even deeper smoky flavor, grill husked corn directly over medium-high heat for 10 to 12 minutes, turning occasionally, before cutting off the kernels.
Serving tip: This salad doubles as a fantastic chip dip — serve it with sturdy tortilla chips for a crowd-pleasing party appetizer.
