How to Make Mexican Street Corn Casserole
- Preheat Your Oven: Begin by preheating your oven to 375°F (190°C). This ensures the casserole will cook evenly.
- Prepare the Corn Mixture: In a large bowl, combine the 40 oz of frozen corn, 2/3 cup mayonnaise, and 2/3 cup sour cream. Mix well until all corn is coated.
- Add the Spices: Stir in 2 tsp chili powder, 3/4 tsp garlic powder, and 1/2 tsp salt to the corn mixture.
- Incorporate Cheese: Crumble 6 oz of queso fresco into the mixture, mixing until evenly distributed.
- Transfer to Baking Dish: Pour the mixture into a greased 9×13 baking dish, spreading it out evenly with a spatula.
- Baking Time: Bake in the preheated oven for about 25-30 minutes, or until the edges are bubbling and the top is lightly golden.
- Garnish: After removing from the oven, sprinkle the dried cilantro over the top. Let it cool for a few minutes before serving for the best flavor.
Storing & Reheating
Store any leftover Mexican Street Corn Casserole at room temperature for up to 2 hours, or in the refrigerator for about 3-5 days in an airtight container. If you want to freeze it, wrap portions tightly and store for up to 3 months. To reheat, simply pop it in a preheated oven at 350°F (175°C) for about 20 minutes, until warmed through. The texture may change slightly, but giving it a stir and refreshing the topping with fresh cilantro can revitalize its appeal.
Chef’s Helpful Tips
- Be sure to cook the corn beforehand if using fresh to ensure a tender bite.
- When mixing ingredients, be careful not to overwork the mixture—just combine until everything is evenly incorporated for a fluffy texture.
- For a spicy kick, consider adding diced jalapeños to the mix before baking.
- If you love crispy toppings, broil the casserole in the last few minutes for a beautifully browned top.
