The History of Traditional Chili Oil (and Why It Matters)

Chili oil traces its origins to regions of China, particularly Sichuan and Guizhou provinces, where dried chilies were infused into oil as a way to preserve flavor and create warmth in cooler climates. Over time, these oils evolved — sometimes smooth and aromatic, sometimes packed with solids like fried chilies, garlic, fermented beans, or shallots.

What’s important is that chili oil was never just about spice. It was about balance: heat, fragrance, texture, and fat working together. Families passed down their own versions, each jar reflecting regional tastes, available ingredients, and personal preference. Some were smoky, some numbing, some deeply savory.

The modern “chili crisp” or “chili onion crunch” popularized in Western kitchens is a descendant of these traditional oils — adapted, commercialized, and simplified for mass appeal. Trader Joe’s Chili Onion Crunch helped introduce this texture-forward condiment to a wider audience, sparking a new generation of chili oil lovers.

This recipe honors that lineage while adapting it for today’s home kitchen.

Why This All-Purpose Crunchy Chili Oil Works

This version focuses on crispy onion and garlic, suspended in oil and layered with chili heat and subtle smokiness. Unlike traditional smooth chili oil, the crunch adds contrast — making it not just a finishing oil, but a textural element in cooking.

Key flavor elements:

• Dried onion for sweetness and crunch
• Dried garlic for depth and savoriness
• Crushed red pepper flakes for warmth
• Chili powder for body and color
• Smoked paprika for gentle complexity
• Olive or neutral oil to carry flavor

The result is a chili oil that feels familiar, yet intentional — rooted in tradition, adapted for modern use.

Why This Crunchy Chili Oil Is a Must-Have

Chili oil–based condiments have come a long way: what began centuries ago as aromatic, infused oils in Chinese cuisine has evolved into modern, globally beloved “chili-crisp” or “chili onion crunch” condiments.

Where many store-bought chili oils remain smooth and pourable, the charm of a crunchy chili oil is in the texture — crispy bits of onion, garlic, and dried chili flakes suspended in oil. That satisfying crunch plus the spicy, smoky, savory depth adds a layer of flavor and complexity that transforms even simple meals.

Whether you’re drizzling it over avocado toast, stirring it into noodles, using it to marinate meat or veggies, or simply dipping crusty bread — this all-purpose chili oil becomes a kitchen staple.

Homemade All-Purpose Crunchy Chili Oil Recipe (Copycat Style)

Ingredients

• Dried minced onion — for crunchy texture and oniony flavor
• Dried minced garlic — adds depth, flavor and extra crunch (optional but highly recommended)
• Crushed red pepper flakes — for the signature heat and chili crunch feel
• Chili powder — deepens the chili flavor beyond just flakes
• Smoked paprika — for subtle smoky undertones (you can use regular paprika if you prefer)
• Sea salt (or kosher salt) — to enhance and round out the flavors
• Olive oil (or another neutral oil like avocado oil) — the base that carries all the flavors and crunch into a luscious oil

Instructions

1. Toast (optional but recommended): In a dry skillet over low heat, lightly toast the dried onion, garlic, and crushed red pepper flakes until they become aromatic and slightly golden. This takes just 2–3 minutes — but it intensifies flavor and deepens the crunch.
2. Cool and Combine: Let the toasted mixture cool briefly, then transfer to a clean, dry bowl or a mason jar.
3. Add Seasonings & Oil: Sprinkle in chili powder, smoked paprika, and salt. Pour in enough olive (or neutral) oil to cover the dried ingredients — typically about ¾ cup for a small batch. Stir well to combine.
4. Let It Marinate: For best flavor, allow the mixture to sit (sealed) for at least 24–48 hours before first use. The flavors deepen as they meld together over time.

Storage: Keep the chili oil in an airtight jar in a cool, dry place (pantry or cupboard). A clean spoon ensures cleanliness every time. If you refrigerate the oil, it may solidify and separate — just bring it to room temperature and stir well before use.

How to use Chili-Garlic Onion Crunch

Chili oil is so incredibly versatile. It can be used in a variety of different dishes and recipes. I use this as one of those essential season-all spices. It can be used as a condiment and before, during, or after cooking.

Before cooking- This all-purpose crunchy chili oil can be used as a marinade for any type of meat, seafood or vegetable.

How to store Chili-Garlic Onion Crunch

I’ve stored this chili oil for 1 year or longer, depending on the expiration date of the oil used, but I’ve got a few tips for how to keep it fresh. The first tip is to keep it in an airtight container in a cool, dry place. I store mine in a mason jar in the pantry away from my stove to keep condensation from forming. I would not recommend keeping it in the refrigerator. Storing this way will cause the olive oil to cool. The oil will become solid and the heavier ingredients will sink to the bottom. The most important things to note are: 

• Always use a clean spoon to stir and scoop out the oil 
• Be sure to secure the lid on your container after use 
• Keep away from extreme hot or cold temperatures
