Red Onion Marmalade is a sweet, tangy, and savory condiment made from slowly caramelized red onions, sugar, vinegar, and spices. This versatile spread is perfect for adding flavor to sandwiches, burgers, or cheese boards. It’s easy to make and can be stored in the fridge for a few weeks, making it a great addition to your kitchen staples.
Ingredients:
- 4 large red onions, thinly sliced
- 2 tablespoons olive oil
- 2 tablespoons butter
- 1/4 cup brown sugar (or granulated sugar)
- 1/4 cup balsamic vinegar
- 1/4 cup red wine vinegar (or apple cider vinegar)
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
- Salt and pepper, to taste
Instructions:
- Prepare the onions: Peel and thinly slice the red onions. Set aside.
- Cook the onions: In a large pan, heat the olive oil and butter over medium heat. Add the sliced onions and stir to coat them evenly in the oil and butter. Cook the onions for about 10-15 minutes, stirring occasionally, until they begin to soften and turn golden.
- Caramelize the onions: Reduce the heat to low and add the brown sugar. Stir to combine and cook the onions for another 20-30 minutes, stirring often, until they are deeply caramelized and sticky.
- Add the vinegar and thyme: Pour in the balsamic vinegar and red wine vinegar, then stir in the thyme. Cook for another 10-15 minutes, allowing the liquid to reduce and thicken. The onions should be soft and jammy at this point. Season with salt and pepper to taste.
- Cool and store: Once the marmalade has thickened, remove it from the heat and let it cool slightly. Transfer the onion marmalade to a clean jar and store in the refrigerator for up to 2 weeks.
Serving Suggestions:
- Serve alongside cheese boards, especially with brie or goat cheese.
- Use as a topping for burgers or sandwiches.
- Spread on crostini for a quick appetizer.
- Add to roasted meats or grilled vegetables for a sweet and tangy flavor boost.
This Red Onion Marmalade is a delicious way to elevate any dish with its sweet and tangy caramelized flavor. Enjoy it as a versatile condiment that brings depth to many meals!
