Spiked Caramelized Onion Spread Ingredients
First assemble the following ingredients:
- Butter or Ghee (2 tbsp) – Butter provides a creamy, rich base that enhances the natural sweetness of the onions as they caramelize, adding a smooth and velvety texture to the dish.
- Onion (1) – Onions develop a deep, sweet flavor when caramelized, transforming their initial sharpness into a mellow, complex taste with hints of natural sugar coming to the forefront.
- Honey (1 tbsp) – Honey introduces a subtle, floral sweetness to the caramelized onions, amplifying their inherent sugary notes and adding a smooth, sticky consistency.
- Whiskey or Bourbon (4 tbsp) – Whiskey adds a smoky, oaky depth to the caramelized onions, contributing a warm, slightly spicy undertone that complements their sweetness. Bourbon caramelized onions are equivalent to those made with whiskey.
- Celtic sea salt (1 tsp) – Celtic sea salt enhances the overall flavor profile with its briny, mineral-rich taste, balancing the sweetness of the onions and honey while highlighting the whiskey’s complexity.
Steps to Make Whiskey Caramelized Onions
Cook onions. In a large pan, melt butter or ghee. Add onions and salt, stir and let caramelize until medium to caramel brown.

Tips and Tricks for Making Caramelized Onions
Choose the Right Onions. Yellow or sweet onions are ideal for caramelizing due to their natural sugar content, which enhances the caramelization process.
Non-Alcoholic Version. For a nonalcoholic version you can use balsamic vinegar in place of the tbsp whiskey.
Low and Slow. Caramelizing onions is a slow process that can’t be rushed. Cook them over low to medium-low heat to allow the sugars to break down gradually without burning.
Stir Occasionally. While patience is key, stirring the onions occasionally ensures they cook evenly and don’t stick to the bottom of the pan.
Deglaze with Honey Whiskey. Once the onions have developed a golden-brown color, add a splash of honey whiskey to deglaze the pan. This releases all the flavorful bits stuck to the bottom and infuses the onions with a rich, complex flavor.
Add Honey at the Right Time. Incorporate honey towards the end of the cooking process to avoid it becoming too caramelized or burning, which could impart a bitter taste.
Adjust the Heat. If the onions are cooking too quickly or starting to burn, lower the heat. If they seem to be cooking too slowly, you can increase the heat slightly but watch them closely.
Be Patient. Good caramelized onions can take anywhere from 30 minutes to an hour. They’re done when they’re a deep golden brown and have a jam-like consistency.
Season to Taste. After deglazing with honey whiskey, taste your onions and adjust the seasoning with salt and pepper as needed.
Storage. If you make a large batch, honey whiskey caramelized onions can be stored in an airtight container in the refrigerator for up to a week, or frozen for longer storage.
