Slow-Cooked Collard Greens in Olive Oil

This recipe for slow-cooked collard greens in olive oil transforms hardy winter greens into a silky, meltingly tender side dish. By gently simmering the leaves with plenty of garlic and a hint of chilli, the greens absorb the rich flavours of the oil while retaining a delicate balance of bitterness and sweetness. It is a sophisticated, vegan-friendly take on a classic comfort food staple that relies on patience rather than heavy fats to achieve its luxurious texture.

Ideal as a healthy accompaniment to roasted roots or a smoky bean stew, this nutritious dish is packed with flavour and essential vitamins. The addition of apple cider vinegar at the end brightens the savoury notes, making it a versatile addition to your weekly repertoire. Serve warm or at room temperature with a final drizzle of high-quality oil.

Ingredients for Slow-Cooked Collard Greens in Olive Oil

  • 120ml extra-virgin olive oil, plus more for drizzling

  • 8 garlic cloves, thinly sliced

  • 1/2 teaspoons crushed red pepper flakes

  • 2 bunches collard greens, ribs and stems removed, leaves torn into 2" pieces

  • Kosher salt

  • 1 tablespoon (or more) apple cider vinegar

  • Generous pinch of sugar

Heat 120ml oil in a large saucepan over medium. Cook garlic and red pepper flakes, stirring often, until garlic is golden, about 4 minutes.

Add collard greens to saucepan a handful at a time, stirring until each addition is wilted before adding the next. Season with salt and add 240ml water. Bring to a simmer, then reduce heat so mixture is at a very gentle simmer. Cover and cook, occasionally removing lid to stir, until greens are tender and very dark green, 1–1 1/2 hours.

Let cool slightly, then stir vinegar and sugar into greens. Transfer to a serving bowl and drizzle with more oil and a splash more of vinegar if desired.
