Want to personalize this Mexican Street Corn Casserole recipe? Here are some of my tried and true tips for changing up this recipe.
- Heat: You always skip the jalapeno to make this side dish more mild, but you can also take it up another notch with some green chiles or a few dashes of hot sauce.
- Cojita or Queso Fresco: Mix some of this popular Mexican cheese into your casserole or sprinkle some over the top while the casserole is still warm from the oven.
All you need are a handful of basic kitchen tools to cook up this delicious Mexican casserole.
- Food Processor
- 13 x 9 inch baking dish
- Cheese Grater
- Refrigerator: Let it cool and then cover in an airtight container and store in the refrigerator for up to 3 days, including the day you made it.
- Freezer: Store in the freezer in an airtight container for up to two months.
- Reheat: Thaw in the Mexican corn casserole refrigerator before reheating, preferably overnight. Allow casserole come to room temperature on your counter for about one hour before starting to reheat. Preheat the oven to 300 and bake for 10-15 minutes. Check regularly that the casserole is heated through to avoid overcooking. Unfortunately 15 minutes may not be enough time.
- If you want a punch of lime flavor. Squeeze some fresh lime juice over the top of the Mexican street corn casserole after it finishes baking.
- Grate your own cheese. Pre-shredded cheese contains anti-clumping agents that do have an effect on how the cheese melts while cooking. Freshly grated cheese is always best for melting.
- Use room temperature ingredients. Bring the eggs and sour cream to room temperature before stirring into the other ingredients. This will help everything combine more easily.
- Be careful to not overmix. This will keep your casserole stays fluffy and tender.

What Makes a Casserole?
I love that you can take something like Mexican street corn and turn it into a comforting, easy-to-make, and often more affordable side dish to feed a crowd. The casserole is the most ingenious meal on the planet. Before Instant Pots, before skillet meals and before slow cookers, there was casserole. Nothing beats it. It has survived for decades as the best way to pile a whole meal into one dish.
Popularized in the 1950s casserole as we know it today was the product of advanced cookware brought to market. Nothing since has replaced the casserole dish, no matter how many bells and whistles we add.
Casserole dishes are easier to clean than any modern appliance and you don't have to worry about them being dishwasher safe.
But wait, there's more! Casseroles are the perfect meals for leftovers. They are conveniently stored in the refrigerator or freezer. Casseroles are impressively economical, which is another reason why they were so popular in the 1950s.
If you can feed your family two meals for the price and effort of only one, why not jump on it? The casserole is the ultimate "set it and forget it" dish and chances are, you have a casserole dish already in your cupboard.
All of this doesn't just apply to evening meals, but to breakfast casseroles as well.
