What Goes Into Caramelized Onions

Caramelized Onions

For the perfect Caramelized Onions, using quality ingredients is key. Each component plays an important role in achieving that sweet, deep flavor. The main players are yellow onions, which bring sweetness and depth, and butter combined with canola oil for the ideal cooking medium. The addition of kosher salt helps to draw out moisture, while fresh thyme adds an aromatic touch. If you want to take it a step further, a splash of white balsamic vinegar at the end can brighten up the dish beautifully.

  • Butter – 2 tablespoons: This creamy fat is essential for achieving that rich flavor and golden color in your caramelized onions.
  • Canola Oil – 1 tablespoon: A neutral oil that helps in cooking the onions without overwhelming their natural sweetness.
  • Yellow Onions – 3 large, peeled, halved, and thinly sliced: The star of the show, these onions are sweet and perfect for caramelization.
  • Kosher Salt – 1 teaspoon: This will help to enhance the flavor and promote browning.
  • Fresh Thyme – 3 sprigs (leaves only): Provides an earthy note that pairs beautifully with the sweetness of the onions.
  • White Balsamic Vinegar – 1 tablespoon (optional): A splash at the end adds a nice brightness and balances the sweetness.

Making Caramelized Onions

Caramelized Onions

Cooking caramelized onions is a rewarding process that requires a bit of patience and care. Here’s how to do it step by step:

  1. Start by melting the butter along with the canola oil in a large cast iron or heavy-bottomed skillet over medium-high heat. The blend of these two fats will give your onions a rich flavor and help them caramelize beautifully.

  2. Once the butter is melted and foamy, add the sliced yellow onions to the skillet. Sprinkle them with the kosher salt and the leaves from the fresh thyme. Stir gently to coat the onions with the fats and seasonings.

  3. Cook the onions for about 5 minutes, stirring occasionally. You want them to start softening but not browning at this point. The key is to allow them to sweat and release their natural sugars.

  4. Reduce the heat to medium-low, and cover the skillet with a lid. This will trap moisture and help the onions cook down evenly. Stir every 10 to 15 minutes, allowing them to develop that gorgeous golden color.

  5. As the onions continue to cook, they will reduce in size and become sweeter and more jammy in texture. You’ll begin to notice a rich, nutty aroma filling your kitchen. It’s tempting to rush this process, but patience is key!

  6. If you notice any browning or crisping at the bottom, don’t fret! Just add a splash of water or broth to deglaze the pan, scraping up any flavorful bits stuck to the bottom.

  7. In the last 10 minutes of cooking, if you’re using it, stir in the white balsamic vinegar. This will add a nice tang to balance the sweetness of the onions.

  8. Continue cooking for up to 1 hour, depending on how deep you want the flavor to be. The longer you cook them, the richer the taste. Once they are deeply caramelized, remove them from heat and enjoy immediately, or store them for later use.

Things Worth Knowing

  • Be Patient: The secret to great caramelized onions is low and slow cooking. Rushing the process will lead to burnt or unevenly cooked onions.
  • Keep Stirring: Regular stirring ensures even cooking and prevents the onions from sticking to the pan.
  • Use a Heavy Skillet: A cast iron or heavy-bottomed skillet retains heat better, resulting in more consistent caramelization.
  • Deglaze as Needed: If the onions start to stick, add a bit of water or broth to help lift the brown bits from the pan for added flavor.
  • Experiment with Herbs: Feel free to add your favorite herbs besides thyme, like rosemary or sage, to enhance the flavor profile.
