Ingredients Equipment Method Notes

Ingredients

  

• 4 large yellow onions about 3 lbs, thinly sliced (approx. 1/8 inch thick)
• 2 tbsp unsalted butter
• 1 tbsp olive oil
• 1/2 tsp salt
• 1/4 tsp black pepper
• 1 tbsp balsamic vinegar optional, for deeper color and tang
• 1 tsp granulated sugar optional, helps with browning
• 1/4 cup water or vegetable broth for deglazing if needed

Equipment

• Large heavy-bottomed pot or Dutch oven
• Wooden spoon or heat-resistant spatula

Method

 

• Peel and trim both ends of the onions. Halve each onion lengthwise through the root end. Place the cut side down and thinly slice each half from root to tip. Aim for consistent, thin slices, approximately 1/8 inch thick.
• In a large, heavy-bottomed pot or Dutch oven, melt the unsalted butter with the olive oil over medium-low heat. The large surface area of the pot helps with even cooking.
• Add all the sliced onions to the pot. It will look like a lot, but they will cook down significantly. Stir to coat the onions evenly with the butter and oil. Add the salt and black pepper, and stir again. The salt will help draw moisture out of the onions, aiding in the caramelization process.
• Cover the pot and cook for 15-20 minutes, stirring occasionally, until the onions have softened and become translucent. This step helps to sweat out moisture and begin breaking down their structure without browning.
• Uncover the pot, reduce the heat to low, and continue to cook, stirring every 5-10 minutes. The goal is a slow, gradual browning. Scrape the bottom of the pot each time you stir to prevent sticking and lift up any flavorful fond.
• After about 30-40 minutes of cooking uncovered, the onions will be golden. If desired, sprinkle in the optional granulated sugar to aid in browning, and/or add the balsamic vinegar for a deeper color and tang. Stir well to combine.
• Continue to cook for another 30-40 minutes (total uncovered cooking time of 60-80 minutes), maintaining low heat and stirring frequently. The onions will gradually transform from golden to a rich, deep amber-brown. They should be incredibly soft, sweet, and jam-like. If any bits stick to the bottom and threaten to burn, add a tablespoon or two of water or vegetable broth and scrape the bottom to deglaze, incorporating the flavorful bits back into the onions.
• The caramelized onions are ready when they are uniformly dark brown (not burnt), very tender, and intensely sweet with a savory depth. Taste and adjust seasoning if necessary. Remove from heat and serve warm, or allow to cool completely before storing.

Notes

Patience is Key: True caramelization takes time. Don't rush the process by increasing the heat, or you'll burn the onions instead of caramelizing them.
Storage: Store cooled caramelized onions in an airtight container in the refrigerator for up to 5-7 days, or freeze for up to 3 months.
Uses: Perfect for topping burgers, steaks, pizzas, tarts, quiches, or stirred into soups and gravies.
