Ingredients
  • 2 medium Yellow Onions
  • 2 tablespoons Olive Oil or Butter
  • 1/4 teaspoon Salt
  • Pinch Black Pepper

Choosing the Right Onion

For soups and stews, yellow onions are generally preferred due to their balanced flavor. White onions have a sharper taste, while sweet onions like Vidalia are best for dishes where a mild, sweet flavor is desired. Ensure the onion is firm and free from soft spots.

Preparing the Onions

Peel the onions and cut them in half from the stem to the root end. Place the flat side down and slice thinly, or dice them into small, even pieces for a more subtle flavor. Uniform pieces will cook evenly.

Selecting the Right Pan

Use a heavy-bottomed pan, such as stainless steel or cast iron, to ensure even heat distribution. Avoid non-stick pans as they may not allow the onions to brown properly. A wide pan allows for better evaporation and prevents steaming.

Heating the Fat

Add the olive oil or butter to the pan over medium heat. Allow the fat to heat up until it shimmers (if using oil) or melts completely (if using butter). Be careful not to overheat the fat, as this can cause the onions to burn.

Sautéing the Onions

Add the onions to the pan and stir to coat them with the fat. Season with salt and pepper. Salt helps to draw out moisture from the onions, which aids in the cooking process. Reduce the heat to medium-low and cook slowly, stirring occasionally, until the onions become translucent and golden brown. This process can take 15-20 minutes.

Achieving the Perfect Color

The goal is to achieve a deep golden-brown color without burning the onions. If the onions start to brown too quickly, reduce the heat further and add a tablespoon of water or broth to deglaze the pan. This will help to loosen any browned bits from the bottom of the pan and add flavor to the onions.

Flavor Enhancement (Optional)

For added depth of flavor, consider adding a pinch of sugar towards the end of the sautéing process. This will help to caramelize the onions and bring out their natural sweetness. You can also add other aromatics, such as garlic or herbs, during the last few minutes of cooking.

Knowing When They're Done

The onions are done when they are translucent, soft, and have a deep golden-brown color. They should have a sweet, mellow flavor. Avoid overcooking the onions, as they can become bitter.
