How to Heat Frozen Corn on the Cob

By Kaitlin Meilert

Corn on the cob is a tasty side dish or snack that's easy to grill, bake, microwave, pressure cook or boil. Cooking it from frozen isn't much different than cooking fresh corn—it just takes a little longer. No need to even thaw frozen corn cobs, but placing them in the fridge in the morning or in the microwave for a few minutes reduces cook time.

How to Heat Frozen Corn on the Cob

Grilling

Step 1

While the grill heats up, rub butter and sprinkle seasonings over each frozen corn cob.

Step 2

Wrap each cob individually in a sheet of aluminum foil.

Step 3

Place the cobs on the grill for 25 to 35 minutes with the lid closed, turning the cobs occasionally.

Baking in the Oven

Step 1

Preheat the oven to 425 degrees Fahrenheit.

Step 2

Rub butter and sprinkle seasonings over each frozen corn cob.

Step 3

Wrap each cob individually in a sheet of aluminum foil.

Step 4

Place the cobs on the upper rack of the oven with an oven-safe dish on the lower rack in case butter drips out of the foil. Bake for 25 to 35 minutes until thoroughly cooked.

Microwave Cooking

Step 1

Place frozen corn cobs in a microwave-safe dish. Add 1/4 cup water and cover with plastic wrap, leaving a small opening for steam to escape. Or, wrap each corn cob individually in damp paper towels.

Step 2

Microwave on high heat until thoroughly cooked.

  • Two to three corn cobs: Heat for approximately 4 to 6 minutes.
  • Four to five corn cobs: Heat for approximately 8 to 10 minutes.

Step 3

Rub butter and sprinkle seasonings over each cooked corn cob.

Pressure Cooking

Step 1

Pour 1 cup water into the pressure cooker.

Step 2

Place frozen corn cobs in the steamer basket and put the basket in the pressure cooker so that it sits just above the water. Close and lock the lid.

Step 3

Place the pressure cooker on the stove over medium-high heat until it comes up to pressure.

Step 4

Reduce heat to medium and cook the corn cobs 4 to 5 minutes.

Step 5

Release the pressure quickly.

Step 6

Remove the corn cobs and butter and season them as desired.

Boiling

Step 1

Pour cold water into a pot large enough to fit the frozen corn cobs. Use just enough water to completely cover the cobs.

Step 2

Bring water to a boil and place the corn cobs into the pot.

Step 3

Boil the corn cobs 5 to 7 minutes or until thoroughly cooked. Carefully remove corn cobs with a pair of tongs, and butter and season as desired.
