Make perfect roasted frozen corn with this easy recipe! Only 3 ingredients are needed to make a delicious corn side dish in less than 30 minutes.
Did you know that you can roast frozen corn? Corn tastes much better when warm, and roasting it is one of my favorite ways to prepare it. As we don't have access to fresh corn for the majority of the year, knowing how to cook frozen corn is an absolute game changer!
I love using frozen corn, and usually prefer it to canned corn. You can buy frozen corn in large bags, which makes it easy to cook exactly what you need.

Frozen corn: Frozen corn kernels or frozen sweet corn are key in this recipe. They can be roasted from frozen, so you don't have to worry about thawing them or defrosting them first.
Salt: The salt adds a little flavor to the corn, but is completely optional. You can omit it if you prefer, or substitute it for any other spices or seasoning that you like.
Olive oil: Roasting vegetables in oil is the best way to ensure that they stay juicy. Olive oil is my cooking oil of choice, but you can also use liquid coconut oil, sunflower oil, canola oil, or vegetable oil.

Add your frozen corn to a baking sheet in a single layer. Add olive oil and salt, and stir to coat evenly. Roast in a preheated oven at 400 F / 200 C for about 20-30 minutes, or until the corn is starting to turn golden brown.
Serve the oven roasted corn immediately, or use it in your favorite dish.
- Line your baking pan with parchment paper to prevent the corn from sticking to it. This is often unnecessary if you use a non-stick baking sheet.
- You can roast corn from frozen. Don't worry about thawing it first. If the corn is already defrosted, or if you're using canned corn, the required cooking time will be substantially reduced.
- Keep an eye on the corn while it roasts, as it can go from perfectly roasted to burned really quickly.
- The exact cooking time can vary depending on several factors. Keep an eye on the food, and adjust the roasting time as required.
Roasted frozen corn is perfect to serve as a tasty side dish with your favorite entrees, or a Mexican Rice Bowl. You can also serve it as a topping for savory dishes, or use it in other recipes.
I love to serve this with Tex Mex or Mexican dishes, like Instant Pot Shredded Beef, Buffalo Chicken Tacos, Shredded Beef Tacos, Ground Turkey Enchiladas, Slow Cooker Honey Mustard Chicken, Sauteed Onions and Peppers or Instant Pot Sausage and Peppers.
You can also add roasted corn to Black Bean Corn Salad, Chicken and Chorizo Pie, or any dishes where you would add corn.
Roasted corn is much more flavorful than using plain, raw, or canned corn, and makes a tasty addition to any salad, stew, or soup.
Adjust the seasoning: You can add so much flavor to the corn by adding extra seasoning or spices. Try adding some cumin, garlic powder, black pepper, onion powder, cayenne pepper, smoked paprika, taco seasoning, Cajun seasoning, fajita seasoning, or any other spices that you like.
Buttered corn: If you love butter on your corn, you can stir through some melted butter with the roasted corn. You can also melt butter in the sheet pan, and use this instead of the cooking oil.
Add other vegetables: Feel free to add other vegetables that you want to roast to the same baking sheet. Roasted frozen cauliflower, broccoli, and carrots can be made in the exact same way. Keep in mind that larger vegetables might require a longer roasting time than corn.
Pan roasted corn: If you don't want to use your oven, you can also create a similar dish by using a frying pan or skillet. I recommend using a griddle pan or cast iron pan. Sautee the corn on medium to high heat for about 10-15 minutes, or until it starts to char.
You can freeze roasted frozen corn for up to 6 months, or refrigerate it for up to 3 days. Reheat it before serving, or enjoy the corn cold in chilled dishes.
If you freeze the roasted corn and then thaw it again, I usually find that it tends to be a little dry. I therefore only recommend using frozen cooked corn in dishes that contain a lot of liquid, for example, soups and casseroles.
This is a great way to meal prep corn, as you can use it in multiple dishes like soups, salads, and tacos throughout the week.

Frozen corn and canned corn taste very similar, and can often be used for the same purpose. I find it more convenient to buy large bags of frozen corn, as it leads to less waste, and it's easier to use the exact amount you need.
Roasting frozen corn with a little salt will give it so much more flavor compared to simply heating it up or boiling the corn on the stove. You can also add butter or seasoning if you want.
