Caramelized Onion Recipe
Caramelized onions are a simple yet transformative ingredient that brings a rich, savory sweetness to any dish. With just three ingredients and a little patience, you can create a deeply flavorful addition that enhances anything from burgers to pizzas and more.
Ingredients and Preparation Essentials
The main ingredients for this recipe are yellow onions, extra-virgin olive oil, and sea salt. Yellow onions are ideal for caramelizing because of their natural sugars, which intensify as they cook, delivering a mellow, sweet flavor. Extra-virgin olive oil helps soften the onions while adding richness, and sea salt draws out moisture, promoting even caramelization.
Yellow onions are the preferred choice for caramelization due to their balanced sweetness and complex flavor. However, red onions can add a milder sweetness, and sweet onions provide a more sugary profile, making them all viable alternatives depending on the flavor you desire.
Step-by-Step Instructions for Perfectly Caramelized Onions
Preparing the Skillet and Heating the Oil
Using a cast iron skillet or heavy-bottomed pan ensures even heat distribution, which is crucial for the gradual caramelization process. Preheating the oil in the skillet helps prevent sticking and gets the onions softening right from the start.
Starting the Caramelization Process
Begin by sautéing the onions over medium heat. This initial cooking phase releases moisture and begins the softening process. Adding sea salt at this stage helps draw out the natural juices from the onions, making them tender and flavorful as they cook.
Slow-Cooking for Deep Flavor
The true magic of caramelization happens with slow cooking. By reducing the heat to medium-low, you allow the onions to cook gradually, deepening in color and sweetness. The process requires patience, but the reward is tender, golden-brown onions with an intense, sweet-savory flavor.
Managing Temperature and Stirring
If the onions start to stick to the pan, lower the heat slightly to prevent burning. For those who prefer a faster caramelization, you can increase the heat slightly after the 50-minute mark, but be sure to stir frequently to avoid scorching the onions. Stirring every few minutes ensures the onions cook evenly and prevents any burnt bits from developing.
Recipe Tips
Achieving a Perfect Golden-Brown Color
Maintain medium-low heat and stir consistently to develop an even golden-brown hue.
Avoiding Stickiness and Burning
If onions start to stick, lower the heat or add a splash of water to release them from the pan.
Adjusting the Flavor
Add herbs like thyme or rosemary, or a splash of balsamic vinegar, for a twist on the classic flavor.

Ingredients
4 medium yellow onions, halved and thinly sliced
2 tablespoons extra-virgin olive oil
½ teaspoon sea salt
Instructions
Warm the olive oil in a 12-inch cast iron skillet over medium heat. Once hot, add the sliced onions and sauté for around 5 minutes until they start to soften.
Sprinkle in the sea salt, then reduce the heat to medium-low. Continue cooking for 50 to 80 minutes, stirring every few minutes. The onions should become incredibly tender, deeply golden, and fully caramelized. Timing will vary based on the onion size and your stove’s heat level.
If you notice the onions beginning to stick, lower the heat further. If, after 50 minutes, they’re not as golden as you prefer, raise the heat slightly to intensify caramelization, but keep stirring frequently to avoid burning.
