How to Make the Recipe
Let’s walk through the steps to make this Easy Street Corn Casserole:
- Preheat your oven to 350°F (175°C).
- Prepare the corn by thawing it if frozen. If using frozen corn, you can thaw it by leaving it at room temperature for a few hours or by microwaving it according to package instructions. If using fresh corn, you can use it as is.
- Mix the base in a large bowl. Combine the corn, mayo, sour cream, chili powder, garlic powder, and salt. Stir until everything is well coated and the flavors are evenly distributed.
- Add the queso fresco and mix gently. You can add it all at once or split it into portions if you prefer a layered effect.
- Transfer to a baking dish and smooth out the top. Sprinkle some extra queso fresco on top if you like it extra cheesy.
- Bake for about 20-25 minutes, or until the top is lightly golden and the casserole is heated through.
- Garnish with cilantro and serve hot. If desired, squeeze a bit of fresh lime juice over the top for that extra burst of flavor.
Pro Tips for Making the Recipe
Here are some tips to make your Easy Street Corn Casserole even better:
- Customize the heat by adjusting the amount of chili powder to your liking. If you prefer a milder version, start with half the amount and taste as you go.
- Add some crunch by sprinkling some crushed tortilla chips or crispy bacon bits on top before baking.
- Make it fresh by using fresh corn if it’s in season. Just be sure to cook it slightly before using it in the casserole.
- Experiment with cheese by using different types of cheese, like cheddar or Monterey Jack, for a different flavor profile.

- As a side dish alongside your favorite grilled meats or as part of a Best Vegetable Casserole spread.

Make Ahead and Storage
One of the best things about this recipe is that it can be prepared ahead of time, making it perfect for busy weeknights or when you need to get a head start on meal prep.
- Make ahead by preparing the corn mixture and storing it in the fridge for up to a day before baking.
