Ingredients

• Onions: Onions are the star of the show in this caramelized onions recipe! You can use brown or white onions and slice them into thin slices.
• Butter: Unsalted butter is best here. You need half a stick or four tablespoons.
• Salt: Salt is added to help break down the onions!
• Optional: For an herby addition, add some sprigs of fresh type! If you want sweeter and darker caramelized onions, add a bit of brown sugar or balsamic vinegar. Don’t add both, just choose between those two options! If using balsamic vinegar, make sure it is a thick, high quality vinegar.

Here’s How to Make It

1. Preheat: Heat a large, non-stick frying pan, shallow casserole or skillet over medium high heat. Add the butter and allow to melt until frothy. (photo 1)
2. Add Onions: Add the onions, salt (and fresh thyme, if using) and once they are sizzling turn the heat down to medium. Cook for 30 minutes, stirring occasionally until they’re soft, but don’t worry if they don’t have any color yet. (photos 2-3)
3. Stir & Continue Cooking: Turn the heat up to medium high and cook for a further 15-20 minutes, stirring often until the onions are light golden and soft. If you’re adding the brown sugar OR balsamic vinegar (don’t add both), add them at the start of this stage. (photo 4)

Expert Tips

• Don’t add salted butter! Don’t be tempted to use salted butter and skip the salt. Adding the salt separately is important for breaking down the onions.
• If you choose to add balsamic vinegar to the onions to make them sweeter and deepen their color, choose a good quality, thick balsamic vinegar! A cheap one that is thin like other wine vinegars will make the onions too acidic.
• Use a heavy bottomed skillet for best results! If you have access to a cast iron skillet or other heavy bottomed skillet, the process will go a little quicker since these pans retain heat consistently!
