Pin A bold and unconventional latte that blends the subtle sweetness of caramelized onions with rich espresso and creamy milk. This avant-garde beverage offers a savory twist on the classic coffee drink, perfect for adventurous palates seeking new flavor frontiers.
The first time I made Onion Latte, my kitchen filled with the rich aroma of caramelized onions meeting espresso. Watching friends react to their first sip was a memorable moment—most were delighted by the unexpected harmony of flavors.
Ingredients
- 1 small yellow onion: Thinly sliced for optimal caramelization.
- 1 tablespoon unsalted butter: Used to caramelize the onion.
- 1/2 teaspoon granulated sugar: Enhances the subtle sweetness of the onion.
- Pinch of salt: Balances the flavors in the onion base.
- 2 shots (60 ml) freshly brewed espresso: Provides the classic coffee foundation.
- 300 ml whole milk (or oat milk for dairy-free option): Adds creaminess and body.
- 1 teaspoon honey or maple syrup (optional): For those desiring extra sweetness.
Instructions
- Prepare the onion base:
- In a small skillet over medium-low heat, melt the butter. Add the sliced onion, sugar, and pinch of salt. Cook slowly, stirring occasionally, until the onions are deeply caramelized and golden, about 12–15 minutes. Low and slow yields the best flavor.
- Blend the caramelized onions:
- Transfer the caramelized onions plus any pan juices to a blender. Add 2 tablespoons of milk and blend until completely smooth. Strain through a fine-mesh sieve to create a silky purée.
- Make the latte:
- Brew 2 shots of espresso and divide evenly between two cups. Add 1 tablespoon of strained onion purée to each cup and stir to combine.
- Froth the milk:
- Heat the remaining milk until steaming. Froth it until creamy and foamy using a frother or whisk.
- Assemble:
- Pour the frothed milk over the espresso-onion mixture. Sweeten with honey or maple syrup if desired. Gently stir and serve immediately.
