Gluten Free Paleo Caramelized Onions
Caramelized onions are one of those kitchen transformations that feel almost magical — a pile of raw sliced onions slowly becoming something deeply golden, jammy, and intensely sweet. This version keeps things beautifully clean, relying on avocado oil and a touch of sea salt to coax out every bit of natural flavor without any added fillers or thickeners that could sneak in unwanted gluten. The optional splash of balsamic vinegar at the end adds a subtle tang and a gorgeous glossy finish that makes these onions look as good as they taste. Low and slow is the whole secret here: the recipe walks you through exactly when to stir, when to scrape up those caramelized bits, and when to add a little water to keep things from sticking before the magic is done. Pile them onto grilled meats, stir them into soups, layer them onto grain-free flatbreads, or eat them straight from the pan — no judgment. They store well and make almost any savory dish taste like you spent way more effort than you actually did.
