  • 6 ears fresh uncooked ears of corn on the cob, shucked and silks removed
  • 3 tablespoons extra virgin olive oil
  • 2 tablespoons kosher salt
  • 1 tablespoon fresh cracked black pepper
  • 4 tablespoons salted sweet cream butter, optional garnish


  • Tear 6 sheets of aluminum foil to wrap the ears of corn. Be sure to measure enough to tuck the ends under to make a good seal.
  • Place 1 ear of corn at the end of one of the pieces of foil.
  • Using a pastry brush, brush the extra virgin olive oil over the surface of the ear of corn. We brushed 1½ to 2 teaspoons over each ear of corn.
  • Sprinkle the kosher salt over the coated ear of corn. We sprinkled 1 teaspoon over each ear of corn.
  • Sprinkle the fresh cracked black pepper on top of the kosher salt. We used ½ teaspoon on each ear of corn.
  • Roll the prepared ear of corn in the piece of foil. Once rolled, tuck the ends under to form a seal.
  • Place the rolled ears of corn in the bottom of the crockpot. Cook on high for 3 hours to 3 hours 30 minutes. Check corn at 3 hours. The ears of corn should be bright yellow. Garnish with 2 teaspoons of salted sweet cream butter per ear of cooked corn, if you choose.


  • You can substitute frozen ears of corn for the fresh ears of corn in this easy recipe. Allow the corn to thaw overnight in the refrigerator before cooking.
  • The easy way to get rid of all those pesky bits of silk is to run the corn cobs under cold water to rinse them off.
  • Each crockpot cooks differently. You can check after the corn has been cooking for 3 hours to see the progress. If the corn has finished cooking at 3 hours, set the temperature to “keep warm” until you are ready to serve.
