What Is Onion Agrodolce?
The word agrodolce comes from the Italian words “agro” (sour) and “dolce” (sweet), and it refers to a sauce or condiment that balances vinegar’s acidity with the sweetness of sugar or honey. When applied to onions, the result is a luscious, jammy topping that’s perfect for both savory and sweet pairings.
Onion agrodolce typically features red onions, which are gently sautéed until soft, then simmered with vinegar and sugar until thick and glossy. The flavor is layered: first sweet, then tart, and finally a mild bite from the onion that rounds out the profile.
How to Make Onion Agrodolce at Home
Creating your own onion agrodolce is surprisingly simple and requires only a handful of pantry staples. Here’s a basic recipe to get you started:
Ingredients:
-
2 large red onions, thinly sliced
-
2 tablespoons olive oil
-
2 tablespoons sugar (white or brown)
-
¼ cup red wine vinegar or balsamic vinegar
-
Salt to taste
-
Optional: chili flakes, rosemary, or thyme for added depth
Instructions:
-
Sauté the onions: Heat olive oil in a skillet over medium heat. Add the onions and cook, stirring occasionally, for about 10–12 minutes, until they’re soft and slightly caramelized.
-
Add sugar and vinegar: Sprinkle in the sugar, stir well, then pour in the vinegar. Bring the mixture to a gentle simmer.
-
Reduce: Let it cook for another 10–15 minutes, stirring occasionally, until the liquid reduces and the onions take on a syrupy consistency.

Season: Add salt to taste, and optional herbs or chili flakes if desired.

Cool and store: Let your onion agrodolce cool before transferring to a jar. It keeps well in the refrigerator for up to 1 week.
