Mexican Street Corn Casserole Recipe – Easy, Creamy & Flavorful Side Dish

What Is Mexican Street Corn Casserole?

Mexican Street Corn Casserole (also known as Elote Casserole) is a hearty, flavorful dish inspired by the popular Mexican street food, Elote. Traditionally, Elote is grilled corn on the cob topped with mayo, cheese, chili powder, and lime. The casserole version takes all those same mouthwatering flavors and combines them into a creamy, cheesy, and slightly spicy baked dish that’s perfect for a crowd.

Over the years, this dish has made its way across borders, becoming a staple at summer barbecues and gatherings in the U.S. and beyond. The casserole variation, which combines the flavors into a baked dish, quickly gained popularity because it’s easy to prepare in large quantities and provides the same delightful flavors without needing to grill corn on the cob.

How Do I Make Mexican Street Corn Casserole?

Making this casserole is as easy as it is delicious. In just a few simple steps, you’ll have a crowd-pleasing side dish ready to serve. Here’s a breakdown of everything you’ll need to create this comforting casserole.

Essential Ingredients for the Casserole Base

For the casserole itself, these ingredients will help create the base, which is rich, creamy, and full of flavor:

• 4 cups fresh or frozen corn kernels (if using frozen corn, thaw it first)
• 1 cup mayonnaise (preferably full-fat for the best flavor)
• 1/2 cup sour cream (adds a tangy, creamy consistency)
• 1 cup shredded cheddar cheese (for melty gooeyness)
• 1/2 cup cotija cheese (or feta, for a salty, crumbly texture)
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1 teaspoon chili powder (more if you want it spicier)
• 1 tablespoon lime juice (adds that signature tang)
• Salt and pepper to taste

Step-by-Step Guide to Preparing the Casserole

Now, let’s get cooking! Here’s how to assemble your casserole:

1. Preheat your oven to 375°F (190°C). This ensures it’s hot enough to get that nice golden top when you bake the casserole.
2. Prepare the corn: If you’re using fresh corn, remove the kernels from the cob. If you’re using frozen, make sure it’s thawed. For canned corn, drain and rinse it well to remove any excess salt.
3. Mix the ingredients: In a large mixing bowl, combine the corn, mayonnaise, sour cream, cheddar cheese, cotija cheese, garlic powder, onion powder, chili powder, and lime juice. Stir everything until it’s fully combined. Season with salt and pepper to taste.
4. Transfer to a baking dish: Pour the mixture into a greased 9×13-inch casserole dish, spreading it evenly.
5. Bake the casserole: Place the dish in the oven and bake for about 25-30 minutes or until the top is golden brown and bubbly.

How to Make the Creamy and Flavorful Sauce

The creamy sauce is what makes this casserole stand out! It’s the combination of mayonnaise and sour cream that gives the dish that rich, smooth texture, while the lime juice and chili powder add the zesty, tangy kick.

If you prefer a thicker sauce, you can stir in a tablespoon of cream cheese to give it even more creaminess, or add a bit of heavy cream to smooth out the sauce if it feels too thick.

Tips for Achieving the Perfect Mexican Street Corn Casserole

To make sure your casserole turns out perfectly, here are some baking tips and topping ideas to help you get it just right!

Baking Tips for the Right Texture

• Don’t overmix the casserole ingredients. Mixing too much can result in a mushy casserole, and we want that nice, chunky texture from the corn. Stir gently to combine.
• Check for doneness: When the casserole is done baking, it should have a golden-brown top with some bubbly cheese around the edges. You can also stick a fork in the center to check that it’s heated through.
• Broil at the end: If you want a crispier top, pop the casserole under the broiler for a minute or two. Just make sure to keep an eye on it, so it doesn’t burn!

Adding Toppings for Extra Flavor and Crunch

If you want to elevate your casserole even more, consider adding these optional toppings:

• Fresh cilantro: A sprinkle of chopped cilantro will add a fresh, herby flavor that pairs well with the creamy casserole.
• Crumbled tortilla chips: For an extra crunchy texture, sprinkle some crushed tortilla chips on top right before serving.
• Chili flakes or hot sauce: If you like it extra spicy, drizzle a bit of hot sauce or sprinkle chili flakes over the top for a kick.
• Lime wedges: Serve with a side of lime wedges so people can add more fresh lime juice to their servings for an added tangy flavor.

To elevate your casserole even more, try adding tortilla chips or crispy bacon bits on top for extra crunch. If you’re looking for more tasty side dishes, check out our 5-Minute Feta Potatoes Recipe – Crispy & Easy.

Can I Make Mexican Street Corn Casserole Ahead of Time?

Yes! One of the great things about Mexican Street Corn Casserole is that it’s super easy to make ahead, which makes it perfect for busy days or special gatherings. Here’s how you can prepare it in advance:

How to Prepare and Store the Casserole in Advance

1. Assemble the casserole: Follow all the steps in the recipe but don’t bake it right away. Once you’ve mixed the ingredients and transferred them to the baking dish, cover the casserole tightly with plastic wrap or foil.
2. Refrigerate: You can store the uncooked casserole in the fridge for up to 24 hours before baking. This is a great option if you’re prepping for a party or a dinner the next day.
3. Freezing option: If you want to make the casserole even further in advance, you can freeze it! After assembling, cover it tightly with plastic wrap and then with foil. Freeze for up to 2-3 months.

Reheating Tips to Maintain Flavor and Texture

When you’re ready to bake or reheat, there are a couple of tips to ensure it tastes just as good as the first time:

• From the fridge: If the casserole has been refrigerated, you can bake it directly from the fridge at 375°F (190°C) for about 30-35 minutes. If it was frozen, let it thaw in the fridge overnight before baking.
• From the freezer: To reheat a frozen casserole, bake it covered for 45 minutes and then uncover it for another 10-15 minutes until it’s bubbly and golden brown. You may need to add a bit of extra baking time depending on the size of your casserole.

Flavor Variations of Mexican Street Corn Casserole

There are so many ways to get creative with your Mexican Street Corn Casserole! While the traditional version is amazing, you can play around with different flavors to match your tastes.

Spicy and Smoky Versions with Chili or Jalapeños

If you’re a fan of heat, adding jalapeños or chili powder can bring an extra kick to your casserole. You can chop up a jalapeño and stir it into the corn mixture or sprinkle a little chipotle chili powder for a smoky flavor.

For an even spicier version, try mixing in cayenne pepper or topping the casserole with sliced fresh chilies before baking!

Vegetarian and Dairy-Free Options

While the traditional recipe is delicious, you can also make this casserole vegetarian or dairy-free. Here’s how:

• For a vegetarian version, you can easily omit the meat (if you’ve added any) and still get a rich, savory flavor. You could also add other vegetables like diced bell peppers, zucchini, or tomatoes to make it more hearty.
• For a dairy-free version, swap out the cheeses for dairy-free cheese or use nutritional yeast for a cheesy flavor without the dairy. Substitute the sour cream and mayonnaise for vegan sour cream and vegan mayo.

FAQs About Mexican Street Corn Casserole

Can I Use Frozen Corn for Mexican Street Corn Casserole?

Yes! Frozen corn works great for this recipe and can save you time. Simply thaw the corn before adding it to the casserole mix. It will have the same great texture as fresh corn once it’s baked. In fact, frozen corn can sometimes have a sweeter flavor, which makes the casserole even better. Just make sure to drain any excess water after thawing it to avoid sogginess.

What Are the Best Cheese Options for the Casserole?

For a rich, creamy casserole, cheddar cheese and cotija cheese are the classic choices. Cheddar provides a smooth melt, while cotija adds a salty, crumbly texture. However, if you prefer something different, you could swap cotija for feta cheese or parmesan for a more pronounced salty flavor. For a dairy-free version, try vegan cheddar or nutritional yeast to keep that cheesy taste without the dairy.

How Long Does Mexican Street Corn Casserole Last in the Fridge?

You can store the casserole in an airtight container in the fridge for up to 4 days. After that, it may start to lose its flavor and texture. To reheat, simply bake it at 350°F for 15-20 minutes or until it’s hot and bubbly again. Freezing the casserole is another great option—it will last in the freezer for 2-3 months. Just make sure to let it cool completely before storing it in a freezer-safe container.

Can I Make Mexican Street Corn Casserole Spicy?

Absolutely! If you love heat, you can add extra spice to the casserole. Consider incorporating jalapeños, chili powder, or chipotle chili powder into the mix for a smoky flavor. For even more spice, try adding cayenne pepper or a splash of your favorite hot sauce to the creamy sauce. Just be sure to adjust the spice levels to your taste!

Can I Make Mexican Street Corn Casserole Ahead of Time?

Yes, Mexican Street Corn Casserole is perfect for meal prep. You can assemble it a day ahead and store it in the fridge until you’re ready to bake. This is especially handy if you’re preparing for a party or gathering. Just reheat it in the oven before serving to make sure it’s nice and hot. Alternatively, you can freeze the casserole for up to 3 months and bake it when needed.

How Can I Add More Crunch to the Casserole?

For an extra crunchy texture, sprinkle some tortilla chips on top of the casserole before baking. You can also try adding crispy bacon bits or even a layer of crunchy fried onions for a different twist. Just be sure to add these toppings in the final few minutes of baking so they stay crisp and don’t burn.

Is Mexican Street Corn Casserole Vegetarian-Friendly?

Yes, Mexican Street Corn Casserole is naturally vegetarian! If you want to make it even more filling, consider adding extra vegetables like bell peppers, zucchini, or black beans. This will make the dish even heartier while keeping it meat-free. If you’re going vegan, simply swap the cheese and sour cream for vegan alternatives.
