🌶️What Are Chiles Rellenos?

Chiles Rellenos (which literally translates to “stuffed peppers”) is a traditional Mexican dish that originated in the city of Puebla. The most authentic versions use Poblano peppers, which are mild, earthy, and large enough to hold plenty of filling. While they can be stuffed with minced meat (picadillo), the most popular and beloved version is stuffed with melting cheese, battered, and fried.

Ingredients
  

The Peppers & Filling:
  • 6 Poblano peppers
  • Mozzarella cheese cut into thick strips for stuffing
  • Oil for roasting and frying
For the Caldillo (Tomato-Guajillo Broth):
  • 6 small tomatoes
  • 4 dried Guajillo peppers
  • 1/4 white onion plus a few extra slices for sautéing
  • 2 cloves of garlic
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoon whole black peppercorns
  • 1 bay leaf
  • 3 cups of water
  • Olive oil
  • Salt to taste
For the Capeado (Egg Batter):
  • 5 egg whites
  • Flour enough for dredging the peppers, plus 1 tablespoon for the batter

Method
 

  1. 1. Prepare the Sauce Base

    Toast the guajillo peppers in a dry pan, being very careful not to burn them to prevent a bitter taste. Once roasted, submerge them in a bowl of hot water to hydrate and soften.

    2. Roast and Peel the Poblanos

    Rub the poblano peppers with a little oil and roast them over an open flame or in the oven until the skin is blistered and charred. Cover them and let them "sweat" for 10-15 minutes. Once sweated, gently rub off the skin, make a lengthwise slit, and carefully remove the core and seeds.

    3. Stuff the Peppers

    Stuff the cleaned poblano peppers generously with the mozzarella cheese. Roll the stuffed peppers in flour until they are completely coated. Set aside.

    4. Make the Tomato Broth (Caldillo)

    In a blender, combine the chopped tomatoes, garlic cloves, quarter of an onion, oregano, whole peppercorns, and the hydrated guajillo peppers with a little splash of water. Blend until smooth.

    5. Cook the Broth

    Heat a drizzle of olive oil in a saucepan and sauté a few onion slices until fragrant. Pour in the blended sauce, add salt to taste, and pour in the 3 cups of water. Let it boil for 16 minutes, then add the torn bay leaf and boil for 10 more minutes. Set aside and keep warm.

    6. Prepare the Fluffy Egg Batter

    In a large, clean bowl, beat the 5 egg whites until stiff peaks form. Once ready, gently fold in one tablespoon of the same flour you used to coat the peppers.

    7. Fry to Golden Perfection

    Heat plenty of frying oil in a deep skillet. Dip the flour-coated stuffed peppers into the egg mixture, ensuring they are well covered. Carefully place them in the hot oil and fry until the egg is thoroughly cooked and golden brown on all sides. Remove and drain on a paper towel.

    8. Serve and Enjoy!

    Reheat the tomato broth. Place the freshly battered peppers directly into the warm sauce (only add the ones you are serving immediately so they don't get soggy). Serve hot alongside white Mexican rice!

Notes

Pro-Tips for the Best Chiles Rellenos

To make sure your chiles rank among the best, keep these traditional techniques in mind:
  • The Sweat Method: Roasting the poblanos isn’t enough; you must let them “sweat” in a covered container or bag. This traps the steam and makes peeling the tough outer skin incredibly easy.
  • Flour the Peppers: Do not skip rolling the stuffed peppers in flour before dipping them in the egg. This acts as a glue, ensuring the fluffy egg batter sticks to the slick surface of the pepper.
  • Don’t Burn the Guajillos: When toasting the dried guajillo peppers for your broth, watch them closely! If they burn, your sauce will taste bitter.

🙋Frequently Asked Questions

What is the best cheese for Chiles Rellenos? While this recipe uses Mozzarella for its excellent melting qualities, traditional Mexican cheeses like Queso Oaxaca or Chihuahua cheese are perfect. Monterey Jack is also a great, easy-to-find substitute.

Are Poblano peppers spicy? Poblanos are generally very mild, ranging from 1,000 to 2,000 on the Scoville scale. However, as the chef in our video notes, occasionally you get a “picantito” (slightly spicy) pepper, which is part of the fun of eating them! Removing all the seeds and veins greatly reduces the heat.

What to serve with Chiles Rellenos? These are hearty and rich, so they pair perfectly with simple, comforting side dishes. White Mexican rice (Arroz Blanco) is the traditional pairing, as it soaks up the delicious tomato-guajillo broth. Warm corn tortillas and a side of refried beans are also fantastic additions.

🍳Equipment You Will Need

Having the right tools ready to go makes the process of roasting, stuffing, and frying much smoother. Here is what you will need:

  • Blender or Food Processor: Essential for pureeing the roasted tomatoes and hydrated guajillo peppers into a perfectly smooth broth (caldillo).
  • Electric Hand Mixer or Stand Mixer: While you can whisk the egg whites by hand, an electric mixer will save your arms and give you the stiff, fluffy peaks required for the perfect capeado in minutes.
  • Large Deep Skillet or Frying Pan: You will need a pan deep enough to hold a good amount of hot oil so the stuffed peppers fry evenly without touching the bottom.
  • Kitchen Tongs or Two Spatulas: Crucial for carefully turning the delicate, battered chiles in the hot oil without piercing the pepper or letting the cheese spill out.
  • Plastic Bag or Covered Container: To trap the steam and let the roasted poblano peppers “sweat,” which makes peeling the tough skin effortless.
