Slow-Cooked Spring onions with Ginger and Chilli

This aromatic vegan side dish transforms humble spring onions into something truly special through slow-roasting. By gently cooking the onions in extra-virgin olive oil alongside garlic, ginger, and dried chillies, they lose their sharp bite and develop a mellow, jammy sweetness with irresistibly crisp edges. The infusion of heat and spice creates a fragrant oil that carries a depth of flavour far beyond the simple ingredient list.

Ideal as part of a plant-based spread or served alongside steamed rice and greens, these slow-cooked spring onions offer a sophisticated balance of savoury and piquant notes. A final splash of rice vinegar cuts through the richness of the oil, providing a bright finish. It is a healthy and versatile addition to any weekend lunch or midweek supper.

Ingredients for Slow-Cooked Spring onions with Ginger and Chilli

  • 350g spring onions, roots trimmed

  • 1/2 head of garlic

  • 1 (2") piece ginger, scrubbed, very thinly sliced crosswise

  • 2 dried chillies de árbol or 1/2 teaspoons crushed red pepper flakes

  • 120ml extra-virgin olive oil

  • 3/4 teaspoons kosher salt

  • 1 tablespoon unseasoned rice vinegar

Place a rack in middle of oven and preheat to 177°C. Toss spring onions, garlic, ginger, chillies, oil, and salt in a shallow 2-qt. baking dish to combine.

Turn garlic cut side down, then roast vegetables, tossing 2 or 3 times, until golden brown, very tender, and crisp around edges, 60–70 minutes. Let cool slightly, then add vinegar and toss to coat.
