Sweet, jammy caramelized onions are one of those kitchen staples that make everything they touch taste more luxurious โ and this version keeps things beautifully simple. Avocado oil does the heavy lifting here, providing a clean, neutral fat that lets the natural sugars in the onions do their thing over low, patient heat. For anyone managing eosinophilic esophagitis, finding condiments and flavor-boosters without hidden triggers can feel like a full-time job, but this recipe strips things back to just a handful of safe, whole ingredients. The slow cooking process โ nearly an hour of gentle stirring โ transforms three humble onions into a deep golden, glossy pile of concentrated sweetness that tastes far more complex than the ingredient list suggests. A splash of balsamic vinegar at the end is entirely optional, but it adds a subtle tang that takes the whole thing to another level. Pile these onto grilled proteins, stir them into mashed vegetables, or use them as a savory base for soups and sauces โ the versatility is genuinely hard to overstate.
