Peanut Free Paleo Caramelized Onions
Caramelized onions are one of those kitchen transformations that feel almost magical — a pile of raw sliced onions slowly coaxing down into something deeply golden, jammy, and rich. Avocado oil does the heavy lifting here, providing a neutral, high-heat-friendly fat that lets the natural sugars in the yellow onions do their thing without any interference. The low-and-slow process is the real secret: patience and occasional stirring over medium-low heat builds that signature depth of flavor you just can't rush. A splash of balsamic vinegar at the end is optional but absolutely worth it, adding a subtle tang that makes the whole pan glossy and even more complex. Store-bought caramelized onions often sneak in additives or oils that can be hard to vet, so making your own with just four clean ingredients is genuinely reassuring. Pile them onto burgers, stir them into soups, tuck them into omelets, or eat them straight from the pan — no judgment here. This is one of those simple, endlessly useful recipes you'll find yourself coming back to again and again.
