1 teaspoon salt – Enhances all the flavors, ensuring that each bite is savory and satisfying.

For the Chili Oil

1 cup neutral oil (such as canola or grapeseed) – This oil serves as a base for infusing flavors without overpowering them.
2 tablespoons soy sauce – Adds a rich umami kick that complements the crispy elements beautifully in your Copycat Chili Onion Crunch.

1 teaspoon sugar – Balances out the heat and saltiness, creating a harmonious blend of flavors in your dish.

How to Make Copycat Chili Onion Crunch

1. Heat the vegetable oil in a frying pan over medium heat. This will create the perfect environment for your onions to fry up crispy and golden.

2. Add the sliced onions and cook until golden brown and crispy, about 15-20 minutes. Stir occasionally to ensure even cooking and prevent burning.

3. Mix in the garlic and red chili flakes, cooking for an additional 2-3 minutes until fragrant. The aroma will fill your kitchen with delightful warmth!

4. Remove from heat and drain on paper towels. Season with salt while they’re still hot for optimal flavor enhancement.

For the Chili Oil:

5. Combine the neutral oil, soy sauce, sesame oil, and sugar in a separate saucepan. This mixture adds depth and richness to your Copycat Chili Onion Crunch.

6. Heat over low heat until warm, stirring to dissolve the sugar completely. Keep it gentle; we want a harmonious blend without cooking away any flavors.

7. Remove from heat and let cool slightly. This step allows all those beautiful flavors to meld perfectly together.

8. Stir in a glass jar, combining the crispy onion mixture and the chili oil you just prepared. Ensure everything is coated beautifully for maximum flavor.

9. Let cool completely before sealing the jar tightly. This helps preserve that fresh taste you’ll love in all your dishes!

10. Store in the refrigerator for up to 2 weeks, although we doubt it’ll last that long once you start enjoying it!

Optional: Drizzle over your favorite noodle dishes or use as a dip!

Tips for the Best Copycat Chili Onion Crunch

Onion Cutting Technique: Ensure your onion slices are thin and even for uniform crispiness. This will help them fry evenly and avoid burning.

Oil Temperature Check: Maintain medium heat while frying the onions. If the oil is too hot, the onions will brown too quickly, becoming bitter instead of sweet and crispy.

Crispy Garlic Addition: Add the garlic only after the onions are nearly done frying. This prevents it from burning, allowing it to develop a lovely golden color and rich flavor.

Chili Flake Balance: Adjust red chili flakes according to your heat preference. Start with less if you’re unsure, as you can always add more later.

Cooling Time Matter: Allow the onion mixture to cool on paper towels thoroughly before combining with chili oil. This ensures they stay crunchy in your Copycat Chili Onion Crunch.

Storage Tips: Use a clean glass jar for storage, and let the mixture cool completely before sealing. This helps maintain freshness and prevents moisture buildup.
