Ingredients
- Yellow onion: 1 small, thinly sliced
- Unsalted butter: 1 tablespoon
- Granulated sugar: 1/2 teaspoon
- Salt: Pinch
- Espresso: 2 shots (60 ml), freshly brewed
- Whole milk (or oat milk): 300 ml
- Honey or maple syrup: 1 teaspoon (optional, for sweetness)
Instructions
- Prepare the onion base:
- In a small skillet over medium-low heat, melt the butter. Add the sliced onion, sugar, and a pinch of salt. Cook slowly, stirring occasionally, until the onions are deeply caramelized and golden, about 12–15 minutes. Do not rush this step—low and slow yields the best flavor.
- Blend the caramelized onions:
- Transfer the caramelized onions and any pan juices to a blender. Add 2 tablespoons of milk and blend until completely smooth. Strain through a fine-mesh sieve to ensure a silky texture.
- Make the latte:
- Brew 2 shots of espresso and divide evenly between two cups. Add 1 tablespoon of the strained onion purée to each cup, stirring well to combine.
- Froth the milk:
- Heat the remaining milk until steaming, then froth using a milk frother or whisk until creamy and foamy.
- Assemble:
- Pour the frothed milk over the espresso-onion mixture in each cup. Sweeten with honey or maple syrup if desired. Gently stir and serve immediately.
