Gluten Free Caramelized Onion Jam
Sweet, deeply savory, and impossibly rich, this caramelized onion jam is the kind of condiment that makes everything it touches taste more special. Slow-cooked yellow onions transform over low heat into something almost unrecognizable — silky, amber, and complex in a way that feels far more impressive than the short ingredient list suggests. Honey adds a gentle floral sweetness, apple cider vinegar brings just enough brightness to cut through the richness, and fresh thyme ties it all together with an herby, aromatic finish. Every ingredient here is naturally free of gluten, so there's no substituting or label-scanning required — just straightforward, wholesome cooking. Spread it over a gluten-free cracker with a wedge of cheese, pile it onto a burger, or stir it into a sauce and watch it disappear. The technique is patient but forgiving, and the payoff is a glossy, jammy spread that keeps in the fridge for days — if it lasts that long.

Add the sliced onions and salt, tossing to coat. Cook over medium heat, stirring every 3–4 minutes, until the onions have fully wilted and turned pale gold, about 20 minutes. If the onions begin to stick or brown unevenly before they have softened, add 1 tbsp of water and scrape up any fond.
