Sweet, deeply savory, and impossibly rich, this slow-cooked onion jam is the kind of condiment that makes everything it touches taste more intentional. Yellow onions are coaxed down over low heat until they collapse into a glossy, amber spread — the kind of transformation that feels almost magical the first time you watch it happen. A touch of honey adds gentle sweetness, apple cider vinegar brings a bright lift, and fresh thyme ties it all together with an herby, aromatic note. Every ingredient here is whole, simple, and nourishing — nothing processed, no additives to second-guess while you're nursing. Butter provides a small but meaningful source of fat-soluble nutrients, and the slow cooking method means no harsh seasonings or hidden extras sneak in. Spoon it over toast, stir it into grain bowls, layer it onto a cheese board, or use it to elevate a simple grilled protein — the possibilities are genuinely endless. Make a batch at the start of the week and you'll find yourself reaching for it constantly.

Melt the butter in a large heavy-bottomed skillet over medium heat until foamy and just beginning to subside.
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.
