Introduction to Crockpot Caramelized Onions

What Are Crockpot Caramelized Onions?

Crockpot caramelized onions are onions slow-cooked over several hours until their natural sugars break down, turning them sweet, soft, and deep golden brown. Unlike stovetop methods, the crockpot version is hands-off, letting you set it and forget it.

Why Use a Crockpot Instead of a Stovetop?

A crockpot offers low, steady heat, which reduces the risk of burning. It also frees you from constant stirring, making it ideal for batch cooking or prepping ahead for the week.
