Step-by-Step Guide: How to Make Onion Marmalade

Gather Your Ingredients

To embark on your onion marmalade-making journey, you’ll need a few key ingredients. Here’s what you’ll need:

  • 4 large onions (preferably red or yellow)
  • 2 tablespoons of olive oil
  • 1 cup of granulated sugar
  • 1/2 cup of red wine vinegar
  • 1/4 teaspoon of salt
  • Optional: Herbs or spices like thyme or black pepper for added flavor


  1. Begin by thinly slicing the onions. The thinner the slices, the quicker they will soften and caramelize.
  2. Heat the olive oil in a large skillet or saucepan over medium heat. Add the sliced onions and sauté until they become translucent and golden brown, stirring occasionally. This process can take approximately 20-30 minutes, so be patient.
  3. Once the onions are caramelized, sprinkle the sugar evenly over them. Stir well to ensure the sugar coats the onions.
  4. Pour in the red wine vinegar and sprinkle in the salt. Stir the mixture to combine all the ingredients.
  5. Reduce the heat to low and let the mixture simmer for about 45 minutes to an hour, or until the liquid has reduced and the mixture has thickened to a jam-like consistency.
  6. If desired, add herbs or spices during the last 10 minutes of cooking for an extra flavor dimension.
  7. Once the mixture has reached the desired consistency, remove it from the heat and let it cool completely.
  8. Transfer the cooled onion marmalade to sterilized jars and store them in the refrigerator. The marmalade can be kept for several weeks.

Tips and Tricks for Perfect Onion Marmalade

  • Be patient when caramelizing the onions. Low and slow is the key to achieving that rich, sweet flavor.

  • Sterilize your jars before storing the marmalade to ensure its longevity.
