This recipe began as a way to use up a big bunch of sweet Texas onions and a handful of fresh thyme, cooking them down into a thick, sweet and savory jam that we intended to throw in the freezer for some future use. But after slathering a spoonful onto homemade bread, we were hooked and the jam never quite made it into the freezer…

We have been relishing the jam on crackers and bread – by itself or with a bit of tangy goat cheese that perfectly complements the onions and herbs.

Although it takes some time on the stove, it’s dead easy to make and a layer of onion-thyme jam could add depth of flavor to all kinds of dishes, from pizzas to tarts and sandwiches. Feel free to try other herbs, too, such as rosemary or sage.
