What is Onion Marmalade?

Onion marmalade is a slow-cooked, deeply caramelized onion condiment that transforms humble onions into a luxurious spread. It’s known for its complex sweet and savory profile, often with a tangy kick from vinegar and a hint of spice. This version embraces that classic taste while being entirely plant-based.

Ingredients

Gather these simple ingredients to create your own gourmet onion marmalade:

  • 1 kg Onions (yellow or red for a twist!)
  • 1/2 cup Balsamic Vinegar
  • 1/2 cup Brown Vinegar
  • 3 cups Brown Sugar
  • 1/4 cup Agave Syrup (a perfect vegan alternative to honey)
  • 1 cup freshly squeezed orange juice
  • 1 Bay Leaf
  • 1 tsp Salt
  • 1/4 cup Olive Oil
  • 1 tsp mustard seeds

Equipment

  • Large heavy-bottomed pot with a lid
  • Food processor (optional, for quick chopping)
  • Sterilized glass jars with lids

Instructions

Follow these simple steps to make your own delicious onion marmalade:

  1. Prepare Onions: Peel and chop the onions. For a large batch like this, using a food processor can save a lot of time, as recommended by the original author.
  2. Combine Ingredients: In your large, heavy-bottomed pot, combine all the chopped onions, balsamic vinegar, brown vinegar, brown sugar, agave syrup, orange juice, bay leaf, salt, olive oil, and mustard seeds.
  3. Slow Cook: Bring the mixture to a gentle boil, then reduce the heat to low. Cover the pot with a lid and let it simmer for 3 hours. This long, slow cooking process is key to developing the deep, rich flavors and caramelizing the onions perfectly.
  4. Thicken: After 3 hours, remove the lid. Continue to simmer for another 30 minutes, stirring occasionally, to allow the marmalade to thicken and reduce to your desired consistency. It should be jam-like and glossy.
  5. Jarring: While the marmalade is still hot, carefully ladle it into hot, sterilized glass bottles or jars.
  6. Seal and Store: Ensure there is no trapped air in the bottles, as this is crucial for the preserve's lifespan. Seal the jars tightly. Once cooled, store your homemade onion marmalade in the refrigerator.

Variations & Adaptations

  • Red Onion Marmalade: As suggested by an abillion user, substitute yellow onions with red onions for a slightly sweeter, milder flavor and a beautiful deep purple hue.
  • Spicy Kick: Add a pinch of red pepper flakes or a dash of your favorite hot sauce during the simmering process for a delightful spicy edge.
  • Herb Infusion: Experiment with fresh thyme or rosemary sprigs added during the last hour of cooking for an aromatic twist. Remove before jarring.
  • Vinegar Swap: Try using red wine vinegar or apple cider vinegar instead of brown vinegar for different flavor profiles.
  • Serving Suggestions: This marmalade is incredibly versatile. Enjoy it with vegan cheese and crackers, spread it on toasted bread, add it to grilled plant-based sandwiches or burgers, use it as a glaze for roasted vegetables like carrots or Brussels sprouts, or even stir it into gravies for extra depth.

Tips & Hacks for the Perfect Marmalade

  • Chopping Onions: While a food processor makes quick work of chopping a large quantity of onions, be careful not to over-process them into a paste. A rough chop is ideal.
  • Sterilization is Key: Properly sterilizing your jars (e.g., in boiling water or a low oven) and filling them hot ensures a longer shelf life for your preserve.
  • Patience Pays Off: The 3.5-hour cooking time might seem long, but it's essential for achieving that deeply caramelized, rich flavor and perfect consistency. Don't rush it!
  • Troubleshooting Consistency: If your marmalade isn't thickening enough in the last 30 minutes, increase the heat slightly and continue to simmer, stirring more frequently, until it reaches your desired thickness. If it's too thick, you can add a tablespoon or two of hot water or orange juice while reheating.

This homemade onion marmalade is a true testament to the fact that gourmet flavors don't have to come with a hefty price tag. It's a delightful, long-lasting condiment that you'll be proud to serve!
