Here’s a simple and flavorful recipe for red onion marmalade—sweet, tangy, and perfect for cheese boards, burgers, or sandwiches.
Ingredients:
- 2 large red onions, thinly sliced
- 2 tablespoons olive oil
- 3 tablespoons brown sugar (or adjust to taste)
- 3 tablespoons balsamic vinegar
- ½ teaspoon salt
- ¼ teaspoon black pepper
- Optional: 1 teaspoon fresh thyme or rosemary
Instructions:
- Heat the oil in a medium saucepan over medium heat.
- Add the sliced onions and a pinch of salt. Cook gently for 10–15 minutes, stirring occasionally, until softened.
- Add the sugar and vinegar, stirring well to coat the onions.
- Reduce the heat to low and simmer for 20–25 minutes, stirring occasionally, until the onions are caramelized and jam-like.
- Season with black pepper and optional herbs. Taste and adjust sugar or vinegar if needed.
- Cool and store in a sterilized jar in the fridge for up to 2 weeks.
Tip: This marmalade is fantastic on grilled cheese, with roasted meats, or even stirred into mashed potatoes for a sweet-savory twist.
I can also give you a quick 10-minute stovetop version that’s less sweet but still delicious if you want it fast. Do you want me to share that?
