Rajas con Crema (Creamy Roasted Poblano Strips)

Method

1. Char the poblanos directly over a gas burner flame, under a broiler, or on a grill. Turn with tongs every 2-3 minutes until the skin is blackened and blistered on all sides — about 8-10 minutes total. The skin should be papery and charred, not just lightly colored. This aggressive charring is the foundation of Mexican pepper preparation — it adds smoky flavor and transforms the pepper's texture from crisp to silky.

2. Transfer the charred peppers to a bowl and cover tightly with plastic wrap or a plate. Let steam for 10 minutes. The trapped steam loosens the charred skin from the flesh, making it easy to peel. After steaming, peel off the blackened skin with your fingers — it should slip off easily. Don't rinse under water; you'll lose the smoky flavor. Remove the stems and seeds, then cut into 1/4-inch strips (rajas).

3. Heat the oil in a large skillet over medium heat. Add the sliced onion and cook for 5-6 minutes until soft and slightly caramelized. The slow-cooked onion adds sweetness that balances the smoky peppers and tangy crema.

4. Add the garlic and corn kernels, cooking for 2-3 minutes until the corn is warmed through and the garlic is fragrant. If using fresh corn, let it get a little color in the pan — the caramelization adds sweetness.

5. Add the poblano strips and stir to combine with the onion and corn. Cook for 2 minutes to warm everything through and let the flavors meld.

6. Reduce heat to low and stir in the crema. Cook for 2-3 minutes until the crema is warmed and coats everything in a silky, tangy sauce. Don't boil — boiling causes crema to separate. If adding cheese, stir it in now and let it melt into the sauce. Season with salt and pepper.

7. Serve warm alongside grilled meats, inside tacos or quesadillas, or as a standalone vegetable side with rice and beans. Rajas con crema is comfort food in Mexico — smoky, creamy, and deeply satisfying.

Equipment

• Gas burner, broiler, or grill (for charring) Recommended: Weber Original Kettle 22-Inch Charcoal Grill · Also good: Weber Original Kettle 22-Inch Charcoal Grill
• Tongs Also good: Wok Spatula
• Large skillet Recommended: Joyce Chen 14-Inch Carbon Steel Wok
• Bowl with plastic wrap (for steaming)

Chef Notes

• The most important thing: Char the poblanos properly. They need to be blackened all over — not just lightly blistered. The char adds smoky depth and makes the skin easy to peel. Use a gas burner, broiler, or grill.
• After charring, steam the peppers in a covered bowl for 10 minutes. The steam loosens the skin so it peels off easily. Don't rinse under water — you'll wash away the smoky flavor.
• Poblanos are mild (1,000-2,000 Scoville). Occasionally you'll get a hot one — taste a small piece after peeling to gauge the heat level.
• Mexican crema is thinner and tangier than sour cream. If using sour cream, thin it with a tablespoon of milk to approximate the consistency.
• Rajas con crema is one of the most versatile Mexican sides — it goes inside tacos, quesadillas, and tamales, or stands alone alongside grilled meats and rice.

Common Substitutions

Ingredient	Substitution	Notes
Poblano peppers	Anaheim peppers or green bell peppers	Anaheim are milder; bell peppers lack the smoky depth
Mexican crema	Sour cream + 1 tbsp milk	Slightly thicker and tangier
Queso Oaxaca	Monterey Jack or mozzarella	Oaxaca melts into strings; Jack melts smoothly
Fresh corn	Frozen corn (thawed)	Works fine — pat dry before adding to the pan

What You're Practicing

Rajas con crema teaches the Mexican technique of charring and peeling peppers — a foundational skill used in salsas, moles, chiles rellenos, and dozens of other dishes. The char-steam-peel process transforms a raw pepper into something smoky, silky, and complex. Once you master this technique with poblanos, you can apply it to any pepper — from mild Anaheims to fiery habaneros. Visit Techniques for more on fire-roasting techniques.

The crema finish demonstrates how dairy (or dairy alternatives) can be used as a sauce component rather than just a topping. Stirring crema into a warm vegetable mixture creates an emulsified sauce that coats and binds — the same principle behind pasta alla vodka, Indian butter chicken, and Hungarian paprikash.
