Once you’ve cut a white onion, it’s best to store the leftover pieces in an airtight container in the refrigerator. This will help keep them fresh and prevent the odor from affecting other foods. Remember to use the leftover onion within a few days for the best quality and taste.

White onions have a milder and sweeter taste when cooked, which can be advantageous in recipes that require a more subtle onion flavor. This makes them particularly suitable in dishes like soups or sauces where you want the onion to complement rather than overpower other ingredients.
When substituting from yellow or red onions, consider the intended outcome of your dish. If a stronger onion flavor is desired, you might want to adjust the quantity or add a pinch of seasoning to enhance the overall taste. It’s all about balancing the flavors to suit your culinary preferences.
How should I prepare white onions for cooking?

Once cleaned, the onion can be sliced, diced, or chopped, depending on your recipe’s requirements. Remember to use a sharp knife to make clean cuts and to minimize teary eyes.
If you’re slicing them for caramelization, thin slices work best as they cook evenly and develop a rich, sweet flavor. For sautéing or adding to dishes, dicing them into small pieces can help distribute their flavor throughout the dish. Adjust the size based on cooking time; smaller pieces cook faster, while larger pieces will retain more texture.
