Trim the ends of the Spanish onion. Cut the onions in half and remove the tough outer skin. Lay the onion flat its cut side, and slice the onion into 1cm thick slices.
Add the oil to a large pan and add the sliced onion. Heat the onions over medium high heat until they start to sizzle about 5 minutes. Stir the onions often to prevent them from scorching and turn the heat down to medium-low. Continue to cook the onions over medium-low heat until they are fully caramelized and golden brown about 30-40 minutes.
Once the onions are a deep golden brown, soft, and sweet, they are finished. remove from the heat and set aside for use in other recipes or enjoy on top of steaks, burgers etc.
