Authentic Mexican Chiles Rellenos with Queso Oaxaca
Master authentic Mexican chiles rellenos with this recipe featuring blistered poblano peppers, melty cheese, and a fluffy egg batter in a savory tomato caldillo.
Mexican chiles rellenos are the hallmark of a patient, skilled home cook. This dish isn't about speed; it is about the transformation of a humble, dark green poblano pepper into a golden, cloud-like parcel filled with molten cheese.
The secret to a perfect chiles rellenos recipe lies in the integrity of the pepper and the lift of the batter. By blistering the skins until charred, we unlock a smoky sweetness that balances the salty richness of the queso Oaxaca. Unlike other stuffed poblano peppers battered in thick dough, this traditional version uses a whipped egg white base to achieve a delicate, airy crunch.
Once fried, these peppers are briefly nestled into a light roasted tomato caldillo. This sauce isn't meant to drown the pepper, but rather to provide a bright, acidic contrast to the fried exterior. Serve these hot with a side of red rice for the ultimate comfort meal.
Ingredients
The Peppers
- 6 large poblano peppers
- 8 oz (225g) Queso Oaxaca or Monterey Jack, cut into thick strips
- 1/2 cup all-purpose flour, for dredging
- Neutral oil for frying (grapeseed or vegetable)
The Egg Batter
- 4 large eggs, separated
- 1/2 teaspoon kosher salt
- 1 tablespoon all-purpose flour
Tomato Caldillo (Sauce)
- 4 large roma tomatoes
- 1/4 white onion
- 2 cloves garlic
- 1 cup chicken or vegetable broth
- 1 teaspoon dried oregano
- Salt and pepper to taste
Instructions
- 1
Char the poblano peppers over an open gas flame or under a broiler, turning frequently until the skin is completely blistered and blackened.
- 2
Place the charred peppers in a bowl and cover with plastic wrap or a lid for 10 minutes to steam; this makes peeling effortless.
- 3
Make the sauce by roasting the tomatoes, onion, and garlic in a dry skillet until charred, then blend with broth and oregano until smooth.
- 4
Simmer the blended sauce in a saucepan over medium-low heat for 10 minutes to thicken slightly; season with salt and keep warm.
- 5
Peel the skins off the peppers gently using your fingers or a paper towel, avoiding tearing the flesh.
- 6
Cut a small slit in the side of each pepper and carefully remove the seed pod; pat the insides and outsides completely dry with paper towels.
- 7
Stuff each pepper with the cheese strips and secure the opening with a toothpick.
- 8
Beat the egg whites with a pinch of salt until stiff peaks form, then gently fold in the yolks and 1 tablespoon of flour until just combined.
- 9
Dredge each stuffed pepper in the 1/2 cup of flour, shaking off the excess, then dip into the egg batter until fully coated.
- 10
Fry the peppers in 1 inch of hot oil (350°F/175°C) for 2-3 minutes per side until the batter is puffed and golden brown.
- 11
Drain the peppers on a wire rack or paper towels for 1 minute to remove excess oil.
- 12
Ladle a pool of warm tomato sauce onto a plate and top with the fried pepper; serve immediately.

Tips
- → Moisture is the enemy of the batter. Use plenty of paper towels to ensure the peeled peppers are bone-dry before dredging in flour.
- → Don't overstuff the peppers. If the slit is too wide or the pepper is too full, the cheese will leak into the oil and cause splattering.
- → Use a toothpick to 'sew' the pepper shut. Just remember to count them so you can remove them before serving to guests.
FAQ
Why does my batter fall off the peppers?
The batter usually slides off because the peppers are still wet or weren't dredged thoroughly in flour. Flour acts as the 'glue' between the smooth pepper skin and the airy egg batter.
Can I make Mexican chiles rellenos ahead of time?
You can roast, peel, and stuff the peppers a day in advance. However, for the best texture, you should batter and fry them immediately before serving so they stay crisp.
How do I keep the peppers from being too spicy?
Most of the heat in a poblano is in the seeds and the internal ribs. Carefully scrape out the veins and seeds after peeling to ensure a mild, family-friendly flavor.
