Ingredients

• 4 large red onions
• 2 tablespoons olive oil
• 3 tablespoons brown sugar
• 4 tablespoons balsamic vinegar
• 2 tablespoons red wine vinegar
• 2 sprigs fresh thyme
• 0.5 teaspoons salt
• 0.25 teaspoons black pepper
• 2 tablespoons water

Directions

Step 1

Peel and thinly slice the red onions into half-moons.

Step 2

In a large skillet or heavy-bottomed saucepan, heat the olive oil over medium heat.

Step 3

Add the sliced red onions and cook for about 10 minutes, stirring occasionally, until softened and slightly translucent.

Step 4

Sprinkle the brown sugar over the onions and stir well to combine. Cook for another 5 minutes to allow the sugar to dissolve and begin to caramelize.

Step 5

Pour in the balsamic vinegar and red wine vinegar, stirring to coat the onions evenly.

Step 6

Add the fresh thyme sprigs, salt, and black pepper. Stir well and reduce the heat to low.

Step 7

Let the onions cook over low heat for 25–30 minutes, stirring occasionally to prevent sticking or burning. If the mixture starts to dry out, add 1–2 tablespoons of water as needed.

Step 8

Once the onions are soft, sticky, and jam-like, remove the thyme sprigs and discard them.

Step 9

Taste the marmalade and adjust the seasoning with additional salt or pepper if needed.

Step 10

Let the marmalade cool slightly before transferring it to sterilized jars or an airtight container. Allow to cool completely before storing in the refrigerator.

Step 11

Serve the red onion marmalade as a condiment with bread, cheese, meats, or burgers.
