It’s time for that delicious summer corn!  So crisp and juicy, there’s no shortage of ways to enjoy it.  And right up there at that top of this list is elote, or grilled Mexican Street Corn.

Coating corn in sour cream mixture and sprinkling on spices to make Mexican Street Corn in foil packets.

A mayonnaise/sour cream mixture like this recipe uses to coat the corn is a great substitute for the Crema Fresca used on authentic Mexican Street Corn. 

If I can find the real thing, I always try to use it.  But sometimes I can’t.  And sometimes I’m in a pinch.  Plus, the oils in the mayo melt as it heats up and seep into the corn making it beyond delicious!

A tented foil packet for baking or grilling Mexican Street Corn.Topped with a sprinkling of chili, cayenne, garlic and salt, this corn has a nice kick!  We love that kind of heat around here, so we aren’t shy about how much we sprinkle.  But if spicy heat isn’t your thing, a light dusting would be the way to go.

Then it’s time to wrap it all up in a foil packet.  Foil pop up sheets make this an easy job!

After baking in a foil packet, Mexican Street Corn being served on a platter.The tented foil packets have several benefits that will change the way you think about grilling or cooking corn. 

  1. The packets trap all the steam that the corn naturally releases as it cooks. That trapped steam makes your corn plump, juicy and tender.
  2. They allow the corn to cook in the seasonings and coating, absorbing all those good flavors, instead of just brushing and sprinkling it all on as toppings.
  3. They offer up some versatility.  The packets allow you to cook this corn on the grill or in the oven.  So even if it rains, delicious corn goodness is still on your menu!
  4.  The packets keep the corn warm after they are taken out of the oven or off the grill.  This is a huge benefit when serving street corn at your backyard cookout.

  • Tent a second foil pop sheet both horizontally and vertically.  Place the tented second sheet on top of the corn and first sheet.  Fold edges of the foil sheets together one or two times around all the edges to create a rectangular packet around the corn.

What is a good substitute for Cojita cheese (in case I can’t find it at my store)?

  • Parmesan or Ramona cheeses are good substitutes for an aged Cojita cheese.

Is this a spicy recipe?

  • It is!  But you can make it less spicy by putting less of the seasoning mixture on the corn or by halving the amount of Cayenne pepper used.

Can Mexican Street Corn be served cold?

  • It is traditionally served hot, right off the grill, at food stands in the streets.  So piping hot is when this corn is at its best, but room temperature will work too if you’re making this for a cookout where there is a crowd.
