Refrigerator Red Onion Jam
If you’re looking for a simple no fuss red onion jam – this is it! Red onions are chopped up, sautéed until caramelized and then they simmer on a low boil until it reaches a jam consistency. I often make a couple batches of this sweet and savory jam with our garden onions, storing the jars in the refrigerator and using them up until they’re gone. It’s perfect for spreading on burgers or sandwiches and on crackers (especially with slices of cheese!). One batch makes approximately a 12 ounce jar of onion jam. You can double or triple it to make more. Looking for more easy jam and spread recipes using your garden veggies? Try my Green Tomato Jam, Green Tomato Relish, 1 Pint Blueberry Jam, Bread Machine Raspberry Jam and Red Onion Chutney.
Ingredients for Onion Marmalade
Red Onions, finely chopped Vegetable Oil White Sugar, you could also use a half white sugar, half brown sugar combo if you want a darker flavor (and color) jam. Seasonings: salt, pepper and garlic powder Red Wine Vinegar, you can also use balsamic vinegar or apple cider vinegar if you would like to.
How to Make Red Onion Jam
Saute the onions and vegetable oil in a large pot until softened. Add in sugar, salt, pepper and garlic powder into the pot, stirring to fully coat the onions. They are going to start caramelize now, and you will start to smell them! This takes about 15 minutes. Pour red wine vinegar into the pot and bring to a low boil. Stir every few minutes until it reaches a thick jam, this usually takes 25-35 minutes. Allow jam to cool and then pour into a mason jar. Store in the refrigerator for 2-4 weeks.
