Erin’s Testing Tips: What We Learned
- Foil vs. Bare Griddle – we tested this recipe both ways and recommend wrapping the corn in foil to help protect it from getting too charred. Cooking sweet corn directly on the hot griddle resulted in very dark corn that looked almost burnt and more chewy corn instead of crisp.
- Rotating the corn every few minutes helps to keep the cooking even and results in less direct charring.

Blackstone Corn on the Cob FAQs
After the first 18-20 minutes, carefully pull back the foil on one ear of corn. It should be bright in color, tender, and juicy. If it isn’t cooked to your desired doneness, cover it back up and keep cooking. Continue to cook in 2 minute increments after 20 minutes, if it isn’t fully done.
Yes, frozen corn on the cob can be cooked on the grill but I do not recommend it. The texture is much more soft and not the same as fresh sweet corn.
Either wrap it back up in foil and store in the fridge for 2-3 days or cut the corn off the cob and store in an airtight container for the same amount of time.
Yes, I would recommend cutting the corn kernels off each cob and store in a freezer-safe container in the freezer for up to 3 months.
