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 first time I experimented with onion in a latte, the aroma filled the kitchen and drew plenty of curious glances. I took a sip and was surprised by how comforting and nuanced the combination was—now it's a quirky favorite for brunches and slow mornings.
Ingredients
- Onion Base: 1 small yellow onion, thinly sliced; 1 tablespoon unsalted butter; 1/2 teaspoon granulated sugar; Pinch of salt
- Latte Components: 2 shots (60 ml) freshly brewed espresso; 300 ml whole milk (or oat milk for dairy-free option); 1 teaspoon honey or maple syrup (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.
