Caramelized onions are one of those kitchen staples that make everything they touch taste more luxurious, and this version delivers that deep, jammy sweetness with just a handful of clean ingredients. Avocado oil stands in for butter or other fats, keeping things grain-free and whole-food friendly while still giving the onions a gorgeous, glossy finish. The real magic here is patience โ a long, slow cook over medium-low heat coaxes out the natural sugars in the onions until they turn silky and rich without any added sweeteners or thickeners. A splash of balsamic vinegar at the end is optional but absolutely worth it, adding a subtle tang that makes the whole thing pop. For anyone navigating tree nut restrictions, this recipe is refreshingly straightforward โ every ingredient is easy to source and there's nothing hidden in the process that could cause concern. Pile them onto grilled chicken, stir them into a grain-free flatbread, or spoon them over a burger and watch them disappear.
