Vegan Italian Sweet and Sour Pearl Onions
Caramelized pearl onions glazed in a tangy-sweet vinegar and brown sugar sauce, studded with toasted walnuts and plump raisins. This Italian-inspired side dish balances sharp malt vinegar with rich nuttiness, serving as a sophisticated accompaniment to roasted meats, charcuterie boards, or alongside crusty bread. The contrast between tender onions and crunchy walnuts makes it equally compelling served warm or at room temperature, making it ideal for entertaining or casual weeknight dinners.

Substitutions
FAQ
Can I make this ahead of time?
Yes, prepare through the glaze stage up to 2 days ahead and refrigerate. Add walnuts and raisins just before serving to maintain their texture. Reheat gently over low heat if serving warm.
What if I don't have malt vinegar?
Red wine vinegar, balsamic, or apple cider vinegar work well as substitutes in equal amounts. Each brings slightly different flavor notes but maintains the sweet-sour balance.
How long will this keep refrigerated?
Store covered for up to 5 days. The onions will soften slightly and flavors will deepen. Reheat gently or serve cold directly from the refrigerator.
