- Chipotles in adobo: Provide smoky heat; swap with chipotle powder or dried chipotle if needed.

Steps To Make this Mexican Street Corn Casserole Recipe

Step One. Make the sauce: in a small food processor combine mayonnaise, sour cream, cotija cheese, chili powder, garlic powder, salt, black pepper, and chipotles in adobo. Pulse until smooth.
Step Two. In a large bowl combine the thawed corn, diced onion, chopped jalapeños (if using), cilantro, and shredded chicken or queso fresco if desired. Pour the sauce over the corn mixture and toss to coat evenly.

Step Three. Transfer the mixture to a greased 9×9-inch (or similar) baking dish. Sprinkle a little extra chili powder and additional cotija or queso fresco on top.

Step Four. Bake at 375°F for 40–50 minutes, until the casserole is heated through, bubbling at the edges, and the cheese is melted and lightly browned. Remove from the oven and garnish with avocado slices, more cilantro, and lime wedges. Serve warm.
What to Serve with Mexican Street Corn Casserole
This casserole stands on its own, but it also pairs well with many dishes:
- Use nachos or warm tortillas to scoop up the creamy corn.
- Serve alongside tacos, fajitas, enchiladas, or grilled meats for a full Mexican-inspired meal.
- Bring it to cookouts—it complements burgers, hot dogs, grilled chicken, and steak.
Recipe Tips
- Char the corn on a grill or under the broiler before mixing for a smoky depth.
- Add crunch: Sprinkle crushed tortilla chips or panko mixed with butter on top before baking.
- Keep warm: For parties, transfer the finished casserole to a slow cooker or chafing dish to hold temperature.
Make Ahead and Storage Tips
Prepare the sauce and corn mixture in advance and keep them refrigerated separately. Assemble and bake just before serving. Store leftovers in an airtight container in the refrigerator for 3–4 days. Reheat in the microwave until hot.
