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.

The creamy, caramelized onion base elevated the espresso without overwhelming it, and my friends were amazed at its depth of flavor. Even skeptics found themselves intrigued after the first sip!
Ingredients
- Yellow onion (1 small), thinly sliced: Forms the base, caramelizes to sweeten the latte.
- Unsalted butter (1 tablespoon): Used to caramelize the onion smoothly.
- Granulated sugar (1/2 teaspoon): Enhances the caramelization and sweetness.
- Salt (pinch): Balances and brings out flavors in the onion.
- Espresso (2 shots, 60 ml): Provides the rich coffee foundation.
- Whole milk (300 ml) or oat milk: Adds creaminess, can substitute for dairy-free version.
- Honey or maple syrup (1 teaspoon, optional): If a touch of sweetness is preferred.
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. 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 smooth. Strain through a fine-mesh sieve for a silky texture.
- Make the latte:
- Brew 2 shots of espresso and divide between two cups. Add 1 tablespoon of onion purée to each, stirring well.
- 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.
Save When I served this for brunch, my family gathered around in curiosity. Instead of the usual pastries, we paired our lattes with cheese croissants, and the savory notes made the morning memorable.
