Pescatarian Paleo Caramelized Onions

Caramelized onions are one of those kitchen transformations that feel almost magical — a pile of raw sliced onions slowly becoming something deeply golden, jammy, and rich over low, patient heat. This version keeps things beautifully simple, relying on avocado oil and a little sea salt to coax out every bit of natural sweetness from the onions without any added sugars or unnecessary extras. The optional splash of balsamic vinegar at the end adds a subtle tang and gives the onions a gorgeous glossy finish that looks like it took way more effort than it did. Because the ingredient list is so clean and plant-based, this fits effortlessly into a pescatarian lifestyle with zero workarounds needed. Pile these onto grilled fish, stir them into a frittata, spread them over a flatbread, or just eat them straight from the pan — no judgment. The low-and-slow cooking method is the real secret here, so resist the urge to crank up the heat and let time do the heavy lifting.
