Slow-cooked until they collapse into a glossy, jammy heap, these caramelized onions are one of those kitchen staples that make everything they touch taste better. The magic here is pure patience โ avocado oil, sliced yellow onions, and a pinch of sea salt are all it takes to coax out that deep, sweet, golden-brown flavor over low, steady heat. Many store-bought caramelized onion products or restaurant versions sneak in added sweeteners to speed up the process, so making your own is the only way to be sure what's actually in the pan. The optional splash of balsamic vinegar at the end adds a subtle tang and a gorgeous gloss without introducing any unwanted ingredients. These are endlessly versatile โ pile them onto burgers, stir them into soups, fold them into egg dishes, or serve them alongside roasted meat. The long cook time is mostly hands-off, and the payoff is a rich, savory condiment that tastes like it took far more effort than it did.
