Caramelized Onions are slow cooked onions cooked down until they turn a golden saucy brown color. They develop a sweet flavor once cooked down and browned and the process is a great way to bring out the best flavor in an onion.

Caramelized Onions are a delicious condiment recipe to enjoy on burgers, sandwiches, as a side to your favorite protein or on top of a grilled steak. I love to have them on hand in the fridge and a quick warm up in the microwave and they are ready for your enjoyment!

What You Need To Make Caramelized Onions

Onions, yellow onions or a sweet onion like the vidalia are the best onions to use when making caramelized onions.

I like to use a combination of butter and olive oil. The butter adds flavor, but the olive oil prevents the butter from burning.

Water, I keep a small measuring cup of water next to the skillet when cooking. This is to help deglaze the pan when the onions begin to dry out. 

Brown Sugar adds a depth of flavor and sweetness to the caramelized onions.

Large skillet, do not use non-stick. A skillet like this one is best.

Tips for Making Caramelized Onions and Substitution Suggestions

  • To cut the onion, cut from the top down to the root. Cut the root out by making a v in the root section. Then slice on the long side of the onion.
  • When adding onions to the skillet, add only a handful at a time, stirring and allowing a little bit of time between adding more onions. This will prevent overcrowding.
  • Use water to help speed the process up, the water will not only deglaze the pan, but it will cause steam that helps cook the onions quicker.
  • Eliminate the brown sugar if you want to make these keto and low carb. Or, substitute golden monkfruit for the brown sugar.
  • Substitute olive oil for the butter for a vegan recipe.
  • Elminate all fat for a fat free recipe. Just be sure to cook the onions very low and slow and use a little bit of water to help them along.
