Slow-cooked until deeply golden and jammy, these caramelized onions are one of those kitchen staples that quietly elevate everything they touch โ from burgers and grain bowls to roasted meats and eggs. The magic here is patience: a long, gentle cook over medium-low heat coaxes out the natural sugars in yellow onions until they collapse into something rich, sweet, and almost silky. Avocado oil keeps the whole process clean and grain-free, making this a reliable go-to for anyone avoiding legumes and the sneaky additives that often come with store-bought versions. A splash of balsamic vinegar at the end is optional but absolutely worth it โ it adds a subtle tang that makes the sweetness pop without overpowering the dish. Just four simple ingredients, and the result tastes like you spent all day in a French bistro kitchen. Make a big batch and keep it in the fridge; you'll find yourself reaching for it all week long.
