Tacos de Rajas (Vegan — Roasted Pepper Tacos)
Mexico; rajas de chile traditions pre-Columbian; tacos as a format documented c. 18th century; tacos de rajas widespread across central Mexican home cooking.
Tacos de rajas — tacos of roasted strip peppers — are one of Mexico's most beloved meat-free preparations, naturally vegan when prepared without the crema that sometimes accompanies them. Poblano peppers are charred directly over flame until the skin blisters completely, then sweated in a bag, peeled, and sliced into strips (rajas). These are cooked with onion and garlic, often with corn kernels added, and seasoned with cumin, salt, and a touch of dried oregano. Served in warm corn tortillas with fresh salsa, sliced avocado, and lime, the result is a complete and deeply satisfying meal. The preparation demonstrates that Mexican cuisine has a deep vegan tradition: corn, peppers, beans, squash, and tomatoes were the four sisters of pre-Columbian cooking, long before livestock arrived with the Spanish. Tacos de rajas are not a vegan substitute for meat tacos — they are an original.
Char the poblanos completely over direct flame or under a hot grill — the skin must blister all over for easy peeling and smoky flavour Sweat in a sealed bag for 10 minutes after charring — the trapped steam loosens the skin for clean peeling Slice into strips against the grain of the pepper — long, even rajas integrate better into the taco than chopped pieces Cook rajas with onion until both are tender and lightly caramelised — the sweetness of cooked onion balances the peppers' mild heat Warm corn tortillas properly — dry comal or heavy pan, 30 seconds each side, wrapped in a towel to steam until soft Layer: tortilla, rajas, salsa, avocado, lime — each element has a role and contributes distinctly
RECIPE: Serves: 4 | Prep: 20 min | Total: 35 min --- 4 poblano peppers 4 Serrano chillies 30 ml neutral vegetable oil 1 medium yellow onion, sliced 3 cloves garlic, minced 100 ml vegetable stock 100 ml full-fat coconut milk (or crema vegana) 75 g Oaxaca cheese alternative or tofu, sliced (optional) 8 small corn tortillas (or flour for vegan) Salt and Tellicherry black pepper to taste 15 g fresh cilantro, chopped --- 1. Char poblano peppers and Serrano chillies over an open flame until blackened on all sides; place in a covered bowl 5 minutes to steam, then peel away charred skin. 2. Remove seeds and stems from charred peppers and chillies; slice into strips. 3. Heat oil in a heavy-bottomed skillet over medium heat; sauté onion until translucent, 4 minutes; add garlic and cook 1 minute. 4. Add pepper strips to the pan, pour in vegetable stock and coconut milk, season with salt and pepper; simmer gently 8 minutes. 5. Warm tortillas in a dry skillet until pliable, 30 seconds each side. 6. Fill each tortilla with pepper rajas, top with cheese alternative if using, fold, and serve topped with cilantro and sour cream alternative. Mix poblanos with pasilla or ancho for a more complex, varied pepper flavour across different heat levels A tablespoon of chipotle in adobo added to the cooking rajas gives a smoky, slightly sweet heat that is deeply Mexican For the most vivid presentation: add a handful of corn kernels roasted until charred in the last minute of cooking — they add sweetness and textural contrast
Under-charring the peppers — pale, partially peeled peppers lack the smoky depth that defines the dish Skipping the bag-sweat — dry-peeling blistered peppers wastes flavour and is much harder Using flour tortillas instead of corn — corn tortillas are essential; their masa flavour is part of the dish's character Forgetting the lime — acid at the final moment brightens everything Adding too many components — rajas are complete with salsa and avocado; resist over-complicating
