Instructions

Preheat the Oven:
Set your oven to three hundred fifty degrees Fahrenheit or one hundred seventy five degrees Celsius. Let it come fully to temperature so the casserole bakes evenly and develops a bubbly golden crust.
Sauté the Corn:
Melt the unsalted butter in a large skillet over medium heat. Add the corn and spread it out in a single layer. Let it cook undisturbed for about five minutes so some of the kernels take on a little color and the natural sweetness intensifies. Stir and cook for another minute if needed.
Build the Flavor Base:
Stir in the diced red bell pepper, sliced green onions, minced garlic, and chopped jalapeño. Cook everything together for two minutes, just until the vegetables soften a bit and the garlic is fragrant. This step builds foundational flavor for the casserole.
Mix the Creamy Sauce:
Grab a large mixing bowl. Whisk together the sour cream, mayonnaise, egg, chili powder, smoked paprika, cumin, salt, and black pepper. Beat it until the mixture is completely smooth with no streaks of egg.
Combine and Fold Ingredients:
Fold the sautéed vegetable mixture into the sauce along with half of the crumbled cotija cheese and half of the shredded Monterey Jack cheese. Gently mix so everything is evenly distributed but do not overmix to keep the texture light.
Prepare to Bake:
Grease a nine by thirteen inch baking dish with butter or nonstick spray to prevent sticking. Pour the full mixture into the dish and use a spatula to spread it into an even layer.
Top with Cheese:
Sprinkle the remaining cotija and Monterey Jack cheeses evenly over the top so the casserole forms a golden cheesy crust as it bakes.
Bake to Perfection:
Place the dish on the center rack. Bake for thirty to thirty five minutes. You want the casserole to bubble and turn golden brown on top, with the edges pulling slightly from the pan. If the top is browning too quickly, cover loosely with foil.
Cool and Garnish:
Remove from the oven and let cool for at least five minutes so it sets up and slices cleanly. Finish with chopped fresh cilantro and plenty of lime wedges for squeezing at the table.

This casserole shines because of how the sweet corn and smoky spices work with tangy cotija. I am always amazed by how the simple step of toasting the corn in butter brings out such a caramelized flavor. My kids now claim this dish as their favorite part of the Thanksgiving spread and even sneak cold leftovers from the fridge.

Storage Tips

Store leftover casserole tightly covered in the fridge for up to four days. It reheats well in the oven or microwave. If you want to prep ahead, assemble the whole dish and refrigerate up to twenty four hours before baking. For longer storage, wrap individual portions and freeze up to three months.

Ingredient Substitutions

If you cannot find cotija cheese, feta stands in beautifully. Greek yogurt works well if you want to swap out sour cream. Try pepper jack instead of Monterey Jack if you like more heat, or toss in extra jalapeño for a spicy twist. If you only have fresh corn during peak summer, cut kernels right off the cob for unbeatable sweetness.

Serving Suggestions

Mexican Street Corn Casserole is a bright side for roasted turkey, grilled meats, or black bean tacos. Spoon it into warm tortillas for a vegetarian taco filling. It is also irresistible with tortilla chips for dipping, especially at casual gatherings and game day spreads.

Cultural Context

Elote is beloved Mexican street fare where grilled corn is slathered with mayo, cheese, and chili powder. This oven baked casserole nods to that heritage by bringing all those bold flavors into an easy shareable format. Every bite transports me back to summer evenings in vibrant markets or neighborhood fiestas.

Seasonal Adaptations

Fresh sweet corn is spectacular in late summer and early fall. In winter, frozen corn ensures peak flavor and convenience. Roasted poblanos or red jalapeños can take the casserole in a smokier or spicier direction. Try a handful of diced zucchini or tomatoes if you are looking to sneak in more veggies.

Let leftovers cool completely before covering to prevent sogginess. A sprinkle of smoked paprika before baking deepens the color and aroma. If making for a crowd you can double the recipe with a disposable foil pan.
