Save 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.
I was skeptical the first time I tried caramelized onions in my morning coffee, but the gentle, sweet-savory flavors surprised me. Now, Onion Latte is a quirky indulgence I enjoy on slow weekends.
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 butter. Add sliced onion, sugar, and salt. Cook slowly, stirring occasionally, until onions are deeply caramelized and golden, about 12–15 minutes. Low and slow yields the best flavor.
- Blend caramelized onions:
- Transfer caramelized onions and any pan juices to a blender. Add 2 tablespoons of milk and blend until smooth. Strain through a fine-mesh sieve for a silky texture.
- Make the latte:
- Brew 2 shots of espresso and divide evenly between two cups. Add 1 tablespoon of strained onion purée to each cup, stirring well to combine.
- Froth the milk:
- Heat remaining milk until steaming, then froth with a milk frother or whisk until creamy and foamy.
- Assemble:
- Pour frothed milk over the espresso-onion mixture in each cup. Sweeten with honey or maple syrup if desired. Stir gently and serve immediately.
