Ingredients You’ll Need
- 40 oz Frozen Corn: This is the star of the show. Frozen corn is sweet and retains its texture well; however, you can use fresh corn if it’s in season for an even better taste.
- 2/3 cup Mayonnaise: Adds creaminess and a slight tanginess. If you prefer a lighter version, Greek yogurt is a fantastic substitute.
- 2/3 cup Sour Cream: This gives a bit of richness. Alternatives include yogurt (plain) for a similar tang without the heaviness.
- 2 tsp Chili Powder: Brings warmth and a hint of smokiness. Feel free to adjust the amount based on your spice preference.
- 3/4 tsp Garlic Powder: It enhances the overall flavor profile. Fresh garlic can also be used—just use about one clove, minced.
- 1/2 tsp Salt: Essential for balancing flavors. Adjust to taste, particularly if you’re using salted cheese.
- 6 oz Queso Fresco: This crumbly cheese adds a delightful creaminess. Feta can work as an alternative if necessary.
- Dried Cilantro, Chopped: Adds a fresh burst of flavor and a lovely color contrast. Fresh cilantro may be used, but you’d need to adjust the quantity since fresh herbs are typically more potent.
How to Make Mexican Street Corn Casserole
- Preheat the Oven: Set your oven to 375°F (190°C), allowing it to reach perfect baking temperature while you prepare the casserole.
- Mix the Base: In a large bowl, combine the 40 oz frozen corn, 2/3 cup mayonnaise, 2/3 cup sour cream, 2 tsp chili powder, 3/4 tsp garlic powder, and 1/2 tsp salt. Stir until well mixed and all the corn is coated.
- Add Cheese & Cilantro: Crumble in the 6 oz queso fresco and fold in the dried cilantro. This will give your casserole that signature creamy texture with pockets of savory cheese and delightful herbal notes.
- Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish, spreading it evenly with a spatula.
- Bake: Place the dish in the preheated oven and bake for about 30-35 minutes, or until the edges are bubbling and the top is lightly golden.
- Cool & Serve: Once done, remove from the oven and let it cool for a bit before serving; this will help the casserole set.
Take a moment to admire that golden top—it’s not just inviting, it’s enticing! Serve it warm, and watch your guests flock to the table.
Storing & Reheating
To store your Mexican Street Corn Casserole, cover it tightly with foil or plastic wrap at room temperature for up to 2 hours. If you have leftovers, transition to the refrigerator in an airtight container for up to 3 days. You can also freeze this casserole—just allow it to cool completely before transferring it to a freezer-safe dish. It will keep well for up to 3 months. When reheating, you can either bake it in the oven at 350°F (175°C) for about 20 minutes until warmed through or microwave individual portions for about 1-2 minutes. Keep in mind that freezing may affect texture slightly, but refreshing it with a bit of sour cream before serving can help!
Chef’s Helpful Tips
- To avoid a watery casserole, make sure not to thaw the frozen corn beforehand; it ensures the right consistency as it cooks.
- Use room temperature ingredients to achieve a smoother texture; letting the mayonnaise and sour cream sit out for about 30 minutes can help.
- If you want an extra flavor kick, add some diced jalapeños or a splash of lime juice to the corn mixture.
- For a crispy topping, consider broiling the casserole for the last 2-3 minutes; just watch carefully to prevent burning.
- This dish can easily be made a day in advance; simply assemble, cover, and refrigerate until you’re ready to bake.
Mexican Street Corn Casserole is not only a fantastic dish to make but one that encourages creativity in the kitchen. The combination of textures and flavors promises satisfaction, whether you serve it at a family get-together or just enjoy it as a comforting meal at home. I hope you make this your new go-to!

Recipe FAQs
Can I use fresh corn instead of frozen for this casserole?
Absolutely! If you have access to fresh corn, it can elevate the dish even further. You’ll need about 6 cups of corn kernels, which should be cooked and cooled before mixing. This would give your casserole a sweeter and more intense corn flavor.
Is it possible to make this casserole gluten-free?
Yes! This recipe is naturally gluten-free as none of the ingredients contain gluten. Always double-check your mayonnaise and sour cream brands if you have gluten allergies to ensure they’re certified gluten-free.
Can I add protein to this casserole?
Of course! Adding shredded chicken or black beans can turn this side dish into a more filling main course. About 2 cups of shredded rotisserie chicken or one can of drained black beans can be mixed in seamlessly.
How can I make this dish spicier?
If you enjoy a little heat, feel free to add chopped fresh jalapeños or even some cayenne pepper to the mix. Additionally, you can top the casserole with a spicy salsa just before serving for an added kick!
