Persian fried onions are the secret flavor weapon in every Persian kitchen. These onions are cooked down in oil until deeply caramelized and soft, which gives them an unbelievably rich, bold depth of flavor. My mom always prepped these in huge batches so she could use them in stews, soups, and all the delicious recipes she made in our home. I’ll show you how she does that, too.

Whether you’re preparing some onions for your favorite khoresh (khoresh e beh is a favorite) or prepping ahead a large batch of fried onions to use later, this recipe will tell you how much oil to use, what heat to cook them on, and how to keep them from burning.

🌟 My Top Tips for the Best Fried Onions

Fried onions are like classic caramelized onions but even MORE flavorful with a bold, sweet, nutty flavor. Master this cooking technique, and it will change your dishes forever.

  • Don’t overcrowd the pan. Don’t crowd the onions too much or they will steam and get soggy, but feel free to load up if you’re going to keep a close eye on them and are willing to regularly remove the excess liquid as the onions cook.
  • Watch for burning. The fewer onions you use, the more likely they are to burn (see note above). My method of cooking also helps reduce the likelihood of burning: cook on medium-high until translucent, then medium until browned. Stir frequently, which makes the browning more even and makes them easier not to burn.
  • Oil usage. You need enough, but not too much. You will need 1 tablespoon of oil per onion for the first 3 onions, and after that, you only need to coat the bottom of the pan, which is approximately a 1/4 cup of oil, depending on the size of your pan.
  • No seasoning yet. There’s no need to add salt when you’re making your Persian onions. I usually add salt when I add them to the recipe that I’m using them in.

Servings: 8 onions
Calories: 106kcal

Ingredients

  • 8 yellow onions see notes
  • ¼ cup oil neutral oil like canola or vegetable

Instructions

  • Prepare the onions by removing the tops, bottoms, and skins. I save the tops and bottoms to use when making Persian Tea Eggs.
  • Cut the onion in half lengthwise, then slice into half moons.
  • You can leave them in half-moons or continue to complete a dice. I prefer them in half-moons when serving as a garnish, and diced for the bases of recipes.
  • Heat the oil in the bottom of the pan over medium high heat.
  • Cook until translucent, then lower the heat to medium and cook beyond when they start to brown. You want bits of caramelization and even some crispiness on the edges.
  • To freeze, place all the onions in a ziplock bag and flatten. Use the back of a knife to mark segments, so you can use the onions in equal amounts later.

Notes

You can use this recipe for 1-8 onions. Use 1 tablespoon of oil per onion for the first 3 onions. For more than 3 onions, use 1/4 cup of oil to coat the bottom of the pan.
