How to Roast Poblano Chiles

Poblano chile, is the large, meaty chile famously used for Chiles Rellenos, Rajas con Queso, Chiles en Nogada, and many more delicious Mexican dishes. In order to make all these delicious dishes, poblanos first need to be roasted until they blacken and blister, then peeled and seeded.

Why Roast Poblano Peppers?

Poblano peppers need to be roasted and peeled before cooking to remove the tough outer skin which is difficult to digest. Charring or roasting poblano peppers livens up your Mexican dishes with smoky sweet flavor!

 Origin of Poblanos

Poblano Chile originated in Puebla, Mexico, a region in the heart of the country. It is said to have grown wild in the mountainous areas near Puebla. Poblanos are one of the most popular peppers in Mexican cuisine.

 Poblano pepper's wide use in central Mexico resulted in good health for its inhabitants – just one Poblano pepper contains 95% of the recommended daily allowance of vitamin C.

3 Methods to Roast Poblano Peppers

  • Oven Roast - Oven or broil roasting
  • Pan roast - Cast iron or comal

With all methods 
  • Start with rinsing poblano peppers

Method #1 - Oven Roast or Broiler

Oven Roast

When roasting poblanos in the oven, they blister more than char, which is perfect for easy peeling of the skin for some Mexican dishes like chile rellenos or chiles en nogada.

  • Place poblanos on a parchment-lined baking sheet

  • Preheat oven to 400° F degrees. Roast for 30-40 minutes, turning after 20 minutes for even roasting.

🞺Broiling is quicker, but you need to keep watch over the peppers.

Set the oven to broil. Place whole poblano peppers on a lightly oiled baking sheet 6 inches from the broiler flame or element, and broil about 5-10 minutes, or until skins are thoroughly blackened, flipping every couple minutes. Remove peppers from heat.

Method #2 - Pan Roast

  • Heat a cast-iron skillet or comal over medium-high heat
  • Pan-roast the whole poblano peppers until all sides are blackened and blistered, about 10 minutes (I recommend turning the stove vent on for any smoke or chile fumes). 
  •  Make sure to rotate the peppers throughout the cooking
  • Place the peppers into a bowl and cover them or a gallon storage bag. Let the peppers sweat for 10-15 minutes.

Method #3 - Stovetop Open Flame

  • Place poblano pepper directly over an open flame. Use tongs to flip the pepper occasionally, until the skin blackens and bubbles, it will start to bubble in 2-3 minutes. 
  • When the poblano is charred on all sides, place it in a plastic storage bag or bowl with a cover to sweat for 10-15 minutes

Time to Peel Poblanos
