Onion Latte with Caramelized Espresso Recipe

Introduction

The Onion Latte Caramelized Espresso is a unique and comforting twist on the classic latte. Combining the rich depth of caramelized onions with bold espresso and creamy milk creates a surprisingly delicious drink that’s perfect for adventurous coffee lovers.

Ingredients

• 1 small yellow onion, thinly sliced
• 1 tablespoon unsalted butter
• 1/2 teaspoon granulated sugar
• Pinch of salt
• 2 shots (2 ounces) freshly brewed espresso
• 1 1/4 cups whole milk or oat milk
• 1 teaspoon honey or maple syrup (optional)

Instructions

1. Step 1: Melt the unsalted butter in a small skillet over medium-low heat. Add the sliced onion, granulated sugar, and a pinch of salt. Cook gently, stirring occasionally, until the onions become deeply golden and caramelized, about 12 to 15 minutes.
2. Step 2: Transfer the caramelized onions along with the pan juices to a blender. Add 2 tablespoons of milk and blend until completely smooth. Then, strain the mixture through a fine-mesh sieve to achieve a refined texture.
3. Step 3: Brew two shots of espresso and evenly divide them between two cups. Stir in 1 tablespoon of the strained onion purée into each cup.
4. Step 4: Heat the remaining milk until steaming. Froth the milk using a milk frother or by whisking vigorously until creamy and foamy.
5. Step 5: Pour the frothed milk over the espresso and onion mixture in each cup. Optionally, sweeten with honey or maple syrup. Stir gently and serve immediately.

Tips & Variations

• For a vegan version, use plant-based butter and oat milk, and sweeten with maple syrup instead of honey.
• Adjust the amount of caramelized onion purée to taste for a milder or stronger onion flavor.
• Try adding a pinch of cinnamon or nutmeg for extra warmth and complexity.

Storage

This latte is best enjoyed fresh but can be stored in the refrigerator for up to 24 hours. Keep the espresso-onion mixture and milk separate, then recombine and reheat gently on the stove or in the microwave before serving. Avoid reheating too long to preserve the texture of the frothed milk.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Will the onion flavor be too strong in the latte?

The caramelization process mellows the onion’s sharpness, resulting in a subtle sweetness and depth that blends well with the espresso. Adjust the amount of onion purée if you prefer a lighter taste.

Can I use regular coffee instead of espresso?

Yes, you can substitute strong brewed coffee, but espresso delivers a more concentrated and robust flavor that balances nicely with the caramelized onion.
