Ingredients You’ll Need
- 40 oz Frozen Corn: Sweet and tender, frozen corn retains its flavor perfectly and is the star ingredient. If you prefer, you can use fresh corn (about 6 ears) or canned corn—just drain well before using.
- 2/3 cup Mayonnaise: This adds creaminess and richness to the dish. If you want a healthier option, Greek yogurt works surprisingly well.
- 2/3 cup Sour Cream: It brings a tangy flavor that complements the sweetness of corn. You can substitute with plain yogurt if you’re looking for a lighter alternative.
- 2 tsp Chili Powder: This spice is vital for flavor, giving the casserole a gentle kick. Adjust the amount according to your heat preference.
- 3/4 tsp Garlic Powder: It imbues the dish with warmth and depth. Fresh minced garlic can also be used; just use about 2-3 cloves.
- 1/2 tsp Salt: Essential for balancing flavors, but feel free to taste and adjust based on your preferences.
- 6 oz Queso Fresco: Fresh and crumbly, this cheese adds an authentic touch. If you can’t find it, feta cheese is a great substitute as well.
- Dried Cilantro, Chopped: A refreshing herb that brightens the dish. If you prefer fresh cilantro, about 1/4 cup chopped can be used. It’s optional, but it really enhances the flavor.
How to Make Mexican Street Corn Casserole
- Preheat the Oven: Begin by preheating your oven to 375°F (190°C). This ensures your casserole bakes evenly and achieves a golden top.
- Mix the Base Ingredients: In a large mixing bowl, combine 40 oz of frozen corn, 2/3 cup of mayonnaise, and 2/3 cup of sour cream. Stir until well mixed, and you’ll see everything coming together beautifully.
- Season the Mixture: Add 2 tsp of chili powder, 3/4 tsp of garlic powder, and 1/2 tsp of salt to the bowl. Blend the spices well into the corn mixture for that flavorful punch.
- Incorporate the Cheese: Gently fold in 6 oz of crumbled queso fresco into the corn mixture. The cheese adds a delightful creaminess that ties the casserole together.
- Transfer to Baking Dish: Grease a 9×13 inch baking dish (or similar-sized casserole dish) and pour the corn mixture in, spreading evenly across the top.
- Bake: Place the dish in the oven and bake for 35 minutes, or until the casserole is bubbling at the edges and lightly browned on top.
- Add Garnish: Once out of the oven, sprinkle with chopped dried cilantro for that fresh touch and presentation.
Storing & Reheating
Leftovers can be stored at room temperature for about 2 hours; beyond that, it’s best to refrigerate. Keep your casserole in an airtight container, and it will stay fresh in the fridge for up to 4 days. For freezing, transfer it to a freezer-safe container and enjoy it within 3 months. When reheating, aim for 350°F (175°C) for about 15-20 minutes, or until warmed through. Note that the texture may change slightly, but refreshing it with a bit of cilantro can help brighten its flavor.
Chef’s Helpful Tips
- Avoid Soggy Casserole: If using fresh corn, ensure you don’t add excess moisture; pat it dry if necessary.
- Mix Cheese Varieties: For a richer flavor, you can mix queso fresco with shredded Monterey Jack or cheddar cheese.
- Bake & Serve: Give the casserole a quick broil at the end for an extra golden finish, but keep a close eye to prevent burning.
- Comfort Food Prep: This recipe can be prepped a day ahead; cover and refrigerate before baking, then pop it in the oven when you’re ready to enjoy.
- Experiment: You can add diced jalapeños for a spicy twist or mix in different herbs to showcase your personal flair.
