  • 3 large Poblano Peppers
  • 1 tablespoon vegetable oil


  • Set your oven to the broiler and position a rack directly beneath the unit, about 4-6 inches.
  • Wash the peppers and pat dry with a paper towel and brush with oil. 
  • Place the oiled peppers on a foil lined baking sheet and transfer to the oven.
  • Broil until the skin of the peppers begins to blister and char, about 5 minutes.
  • Flip the peppers to the other side and repeat.
  • Remove the baking sheet from the oven and cover with another piece of foil, crimping around the edges to retain the steam.  Let them sit for 5-10 minutes until cool enough to handle.
  • With your fingers pull off the charred skin, or use a paper towel to gently wipe the peppers to remove the skin.    
  • Open the skinned peppers and scrape out the seeds and veins.  
  • Use according to your recipe.


For a more smoky flavor, leave some of the charred skin.
