How to Make Caramelized Onions

My guide on how to make caramelized onions, which add rich flavor and flair to any dish!

 

Have you ever wondered how to make caramelized onions?  Caramelized onions are a great way to add rich flavor and flair to a dish.  

Adding caramelized onions to pretty much any dish will take it to the next level. They're one of my favorite secret ingredients, along with roasted garlic.

They're delicious piled onto sandwiches, burgers, flatbread, and pizza.  You can use them to top steak, chicken, pork or fish.

I also love to stir them into omelettes, pasta dishes, dips, casseroles, and even mashed potatoes. And who can forget the timeless classic, French onion soup, made with caramelized onions in a savory broth topped with plenty of gooey cheese.

The process of caramelizing onions requires a little time and attention and you can't really rush the process. As the onions cook, their natural sugars will brown and develop a rich, sweet flavor.  This takes about 45 minutes.

 I usually make a large batch and store them in the fridge. Then you can add them to your dishes for an instant flavor bomb! 

How to Make Caramelized Onions Step-By-Step

Start by heating some oil in a thick-bottomed sauté pan over medium heat.  Add the onions and stir to coat them with the oil.

After about 10 minutes, when the onions start to soften, stir in a small amount of salt. You can also add a small amount of sugar to help the caramelization process but this is optional.

Continue to cook the onions, stirring occasionally (about every 5-10 minutes), until they are golden brown and caramelized.  This will take an additional 35-45 minutes depending on how brown you want them. 

As they cook, scrape up the fond (the brown bits) on the bottom of the pan and mix it into the onions.  If the onions start to burn or catch bottom, add a small amount of wine or water to the pan. The key is to let the onions stick a little to the pan and brown but not long enough so that they burn.

Once the onions are done, add a small amount of wine or other liquid like balsamic vinegar or water. Stir to release all of the brown bits from the bottom of the pan. You're caramelized onions are now done and ready to be added to your dishes!

Instructions

• Heat the oil in a large, thick-bottomed sauté pan over medium heat and add the onions.
• Stir to coat all of the onions with oil. Cook, stirring occasionally, about 10 minutes until the onions start to soften. Add ¼ teaspoon salt and thyme and stir to combine. If desired, you can also add a small amount of sugar (about ¼ teaspoon) to help the onions caramelize but this is optional.
• Continue to cook the onions, stirring occasionally, until they are golden brown and caramelized, another 35-45 minutes. As they cook, scrape up the fond (the brown bits) on the bottom of the pan and mix it into the onions. If the onions start to burn or catch bottom, add a small amount of water to the pan.
• Once the onions are done, add a couple of tablespoons of water to the pan and stir to release all of the brown bits from the bottom of the pan.
• Cool the onions, than transfer them to a cutting board and chop them.
• Mix the yogurt, sour cream, garlic powder, Worcestershire sauce, ½ teaspoon salt and pepper together in a bowl. Set aside a small amount of caramelized onions for garnish and stir the remaining onions into the yogurt mixture until distributed throughout. Garnish with reserved onions and serve. For maximum flavor, make the dip a few hours before serving.
