Rich Red Wine Caramelized Onion Jam
Elevate your burgers and cheese plates with this rich, jammy caramelized onion condiment. Slow-cooked with red wine and balsamic vinegar for depth and sweetness.
Caramelized onion jam is a quintessential component for transforming simple dishes into gourmet experiences. This method balances the natural sugars of yellow onions with the acidity of red wine and balsamic vinegar, resulting in a deeply savory, sticky, and complex spread that pairs perfectly with sharp cheeses or grilled meats.
Ingredients
- 1.3 kg onions
- 5 g olive oil
- 30 ml red wine
- 15 ml balsamic vinegar
- 50 g butter
- 3 g sugar
- 2 g salt
- 2 g black pepper
Instructions
- 1Deglaze the onions

Add 5 grams of olive oil and a splash of red wine to the sautéed onions. Continue to cook over low heat, stirring continuously to allow the liquids to combine and help the onions release their flavors.
Tip: Keep the heat controlled during this stage as the butter can brown quickly; stirring consistently keeps the onions moving and prevents burning. - 2Sauté the onions

Keep the onions moving continuously over the heat to ensure even cooking. As they release their natural moisture, they will begin to soften and slowly transition toward a darker, clumped texture. Monitor the heat carefully so the mixture cooks down without burning.
Tip: Keep the heat low and stir frequently; patience is key to achieving a sweet, deep caramelization without scorching the butter. - 3Finish with balsamic vinegar

Add a drizzle of balsamic vinegar and the black pepper to the mixture. Stir continuously over low heat until the onions have reduced and developed a deep, jam-like consistency.
Tip: For the best texture, ensure the onions are soft and well-clumped together before removing from the heat.
