Cauliflower Al Pastor Tacos
Vegan al pastor tacos with cauliflower marinated in achiote, chilli and pineapple.
About this recipe
Cauliflower marinated in achiote paste, guajillo chilli and pineapple juice, roasted until caramelised and served in corn tortillas with fresh pineapple, white onion and coriander. A vegan take on the iconic al pastor taco.
History & Origin
The al pastor taco is one of Mexico's most beloved street food icons, with roots tracing back to Lebanese immigrants who arrived in Mexico in the early twentieth century. They brought with them the shawarma technique — meat marinated in spices and cooked on a vertical rotisserie — which Mexicans adapted with characteristic creativity: pork replaced lamb, chillies and achiote were added, and the unmistakable sweet-sour note of pineapple became essential. Thus the trompo de pastor was born, a dance of flavours that today feeds millions from the taqueras of Mexico City's historic centre to the night-time street stalls of Guadalajara and Monterrey. In recent decades, vegan Mexican cooking has flourished, driven both by a new generation of conscious cooks and by the deep vegetable traditions that have always characterised pre-Hispanic cuisine. Cauliflower has become the star ingredient of this transformation: its fibrous texture and ability to absorb marinades make it ideal as a meat substitute in bold, heavily spiced preparations. In this recipe, the cauliflower is marinated with the same pillars of authentic al pastor: achiote paste, which contributes an earthy ochre colour and depth of flavour; guajillo chilli with its gentle, fruity heat; vinegar to tenderise the florets; and pineapple juice to balance everything with tropical sweetness. Roasted at high heat, the florets caramelise and develop a slightly charred crust with smoky notes that evoke — without imitating — the experience of the trompo. Served on freshly warmed corn tortillas with caramelised pineapple, finely chopped onion and fresh coriander, this recipe proves that the best of Mexican tradition can be reinvented without sacrificing flavour or cultural identity.

Method
- 1
Blend the soaked guajillo chillies with the achiote paste, the juice from 100g of pineapple, the vinegar, the salt and a splash of water until you have a smooth marinade.

💡 If the marinade is too thick, add one or two tablespoons of water.
- 2
Toss the cauliflower florets and pineapple pieces with the marinade, ensuring every piece is well coated. Leave to rest for at least 15 minutes, or up to 1 hour in the fridge for more intense flavour.

💡 The longer it marinates, the deeper the flavour will be.
- 3
Preheat the oven to 220°C (or heat a cast-iron pan over high heat). Spread the marinated florets on a lined baking tray without crowding them.

💡 Spacing the florets allows them to roast and caramelise rather than steam.
- 4
Roast for 25–30 minutes, turning the florets halfway through, until golden and lightly charred at the edges. The pineapple pieces should be caramelised.

💡 For a smokier result, switch to the grill setting for the last 3 minutes.
- 5
Warm the corn tortillas in a dry frying pan or griddle over medium-high heat, 30 seconds per side, until small golden spots appear.

- 6
Assemble the tacos: place a portion of al pastor cauliflower and roasted pineapple on each tortilla. Top with finely chopped onion, fresh coriander and a wedge of lime.

- 7
Serve immediately with green or red salsa to taste. The tacos are at their best when the cauliflower is still hot and slightly crispy.

💡 Pair with a glass of agua de Jamaica (hibiscus water) for the full Mexican street food experience.
