Make homemade chili onion crunch with olive oil, crispy onion, garlic, and chili flakes. This easy, spicy condiment is perfect for eggs, pizza, noodles and more.

If you love the bold, savory crunch of Trader Joe’s Chili Onion Crunch, you’re going to love this homemade version. I was inspired by Trader Joe’s and all the chili oils and chili crisps that seem to be trending right now. It’s incredibly easy to make and adds a delicious combination of spicy, salty, savory crunch to just about anything.

What Is Chili Onion Crunch?

Chili onion crunch is a spicy, savory condiment made with olive oil, chili flakes, dried onion, and garlic. This homemade version is simple and flavorful, with crunchy onion and garlic in every bite.

Ingredients

  • 1 teaspoon sea salt
  • 1 teaspoon sugar
  • 1 cup extra-virgin olive oil
  • 5 tablespoons red pepper flakes
  • ½ cup dried chopped onion
  • 1 teaspoon dried minced garlic flakes

Eqipment

  • Small saucepan
  • Glass jar with lid

How to Make Your Own Chili Onion Crunch

Step 1

Add all ingredients to a small saucepan.

Step 2

Bring to a simmer over medium-high heat, stirring occasionally to combine.

Step 3

Once the mixture starts to bubble, turn off the burner and leave the pan in place to cool.

Step 4

Let cool in the pan for approximately 30 minutes to 1 hour, or until cooled to room temperature.

Step 5

Once cooled, transfer to a clean glass jar with a lid.

Step 6

Store in the refrigerator and use within 1 week. Stir well before each use. The salt and sugar will settle to the bottom because they do not dissolve in the oil.

Food Safety & Storage

Because this recipe contains dried garlic and onion in oil, it should be refrigerated rather than stored at room temperature. Transfer the cooled chili onion crunch to a clean, airtight glass jar and refrigerate.

Always use a clean utensil when serving and return the jar to the refrigerator after use.

How to Serve Chili Onion Crunch

Chili onion crunch is an easy way to add spicy, savory flavor and crunch to so many dishes. Try spooning it over:

  • Eggs or omelets
  • Avocado toast
  • Pizza
  • Noodles or rice
  • Roasted vegetables
  • Chicken
  • Potatoes
  • Grain bowls
  • Tacos
  • Cottage cheese topper

Tips for Making Chili Onion Crunch

  • Let the mixture cool completely before transferring it to a jar.
  • Use a clean, dry glass jar for storage.
  • Adjust the amount of chili flakes to suit your preferred level of heat.
  • Refrigerate after making and use within the recommended storage period.

Is Chili Onion Crunch the Same as Chili Crisp?

Chili onion crunch and chili crisp are similar, but they aren't exactly the same. Both are spicy, crunchy condiments made with oil, chili peppers, and crispy ingredients such as onion or garlic.

Chili crisp is generally associated with Chinese cuisine and often contains additional ingredients such as Sichuan peppercorns, soybeans, or other aromatics. Chili onion crunch is a simpler version that puts the focus on chili, onion, and garlic.

What Can I Use Instead of Chili Onion Crunch?

Chili crisp or chili oil can be used instead of chili onion crunch, depending on the recipe. If you want a similar texture, choose a chili crisp that contains crispy onion or garlic.
