Chili Garlic Oil
This deeply aromatic chili garlic oil transforms ordinary dishes into something extraordinary. Thinly sliced garlic crisps to golden perfection in fragrant oil, then blooms dried chilies and warm spices to create a condiment with layers of heat, crunch, and complex savory depth.

Directions
- Set Up the Spice Bloom Bowl
Just before cooking, combine chili flakes, smoked paprika, optional Sichuan pepper, cumin, flaky salt, and soy sauce in a heatproof bowl. Keep it beside the stove — timing matters once the oil is ready. - Start Garlic and Shallot in Cold Oil
Place neutral oil in a small heavy saucepan and add sliced garlic and shallot to the cold oil. Heating them gradually ensures even dehydration and prevents burnt exteriors with soft centers. - Cook Until Lightly Golden
Warm over medium heat, stirring occasionally. Listen for a steady sizzle and watch closely as the garlic shifts from pale to evenly golden, about 3–4 minutes. Remove from heat before it turns brown. - Let the Oil Cool Briefly
Allow the hot oil to rest for about 30 seconds. This slight cooling prevents spices from scorching while still providing enough heat to extract aroma and color. - Bloom the Chili and Spices
Pour about half the hot oil over the spice mixture. Stir quickly as the chilies sizzle and darken slightly. Add the remaining oil along with the crispy garlic and shallot. - Finish and Cool the Chili Oil
Stir in toasted sesame oil and mix thoroughly. Let the chili oil cool completely before tasting and adjusting salt — the perceived heat intensifies as it rests.
*Notes :
- The cold oil start for frying garlic is one of the most useful techniques in Chinese cooking. It applies to shallots, ginger, and other aromatics as well. The principle is consistent: starting in cold or cool fat allows moisture to evaporate gradually through the solid rather than creating a sudden steam explosion when wet food hits very hot fat, which unequally cooks the exterior while leaving the interior underdeveloped.
- Korean gochugaru chili flakes are specified as the preferred option because they produce a uniquely beautiful deep red color, a medium heat level, and a slightly sweet, fruity chili flavor compared to standard red pepper flakes. Standard red pepper flakes work perfectly well but produce a sharper, more one-dimensional heat. Sichuan pepper is not related to black pepper — it is a berry from the prickly ash tree that produces a distinctive numbing, tingling sensation rather than heat.
- The soy sauce addition serves two purposes: it adds umami depth that amplifies the garlic and chili’s savory qualities, and its moisture content releases a burst of steam when the hot oil contacts it in the bloom bowl, which helps distribute the aromatic compounds throughout the oil more thoroughly.
Why This Recipe Works
The recipe works through two distinct heat applications: first, gentle frying that slowly dehydrates and crisps the garlic without burning; second, blooming that uses the still-hot oil as a vehicle to quickly extract and amplify the fat-soluble aromatic and color compounds in the dried chilies and spices. These two processes create an oil with multiple textural and aromatic layers — crispy solids, infused oil, bloomed spices — that bottled versions cannot replicate.
Ingredient Breakdown
Neutral Oil
High smoke point carrier that does not compete with the delicate aromatic compounds of the garlic, chilies, and spices.
Garlic (Cold-Oil Fried)
Creates crispy golden pieces with nutty, sweet flavor and a satisfying crunch.
Gochugaru Chili Flakes
Primary heat and color source — fruity, moderately spicy, and visually beautiful.
Smoked Paprika
Adds sweet smoky depth and deepens the red color.
Sichuan Pepper (optional)
Provides the distinctive tingly, numbing sensation characteristic of authentic Chinese chili oils.
Toasted Sesame Oil
Added off-heat to preserve its volatile aromatic compounds — provides the nutty, distinctively Asian finish note.
Flavor Structure Explained
This chili oil follows a layered balance model:
- Crispy aromatic lead (garlic)
- Warm spiced oil base (chili, smoked paprika)
- Tingling heat layer (Sichuan pepper)
- Nutty aromatic finish (sesame oil)
- Savory background (soy sauce)
Crispy garlic defines the first impression, delivering a fragrant, nutty crunch that leads both texture and flavor. The infused oil forms the core, carrying chili heat and smoked paprika depth in a warm, cohesive layer. Sichuan pepper, when used, adds a secondary sensory dimension — a tingling numbness that amplifies perceived heat. Sesame oil rounds the profile with a distinct nutty aroma that lingers at the finish. Soy sauce sits underneath as a subtle savory base, enhancing and integrating all elements without stepping forward.
Common Mistakes to Avoid
- Adding Garlic to Hot Oil – Hot oil fries the exterior before the interior dehydrates, producing unevenly cooked garlic that burns before it crisps. Always start in cold oil.
- Burning the Chili Bloom – Oil that is too hot when poured over the chili flakes will burn them instantly, producing a bitter, acrid oil. Let the oil cool slightly for 30 seconds after removing from heat before blooming.
- Adding Sesame Oil While Hot – Sesame oil’s aromatic compounds are volatile and will evaporate if added to hot oil. Always add off-heat after the oil has bloomed.
Variations
Extra Crispy Version
Add 20g of thinly sliced shallots and fry with the garlic for more texture and sweet allium flavor.
Sichuan Style
Double the Sichuan pepper, add 5g black bean paste, and use exclusively gochugaru for an authentic Sichuan mapo-style oil.
Mild Version
Reduce chili flakes to 5g and use all sweet paprika for a fragrant, barely spicy version.
Herb Chili Oil
Add 5g dried oregano and 5g dried basil to the spice bloom for an Italian-inspired version excellent on pizza and pasta.
Storage & Make-Ahead
Store in an airtight glass jar at room temperature for up to 2 weeks, or refrigerate for up to 1 month. The flavors deepen and improve over the first 2–3 days as the chili and spice compounds continue infusing into the oil. The crispy garlic will soften slightly over time as it absorbs oil — this is normal and does not affect flavor. Stir before each use to redistribute the solids.
Frequently Asked Questions
What are the best uses for chili garlic oil?
Noodles of any kind; dumplings and wontons; fried or scrambled eggs; steamed or stir-fried vegetables; rice; pizza; avocado toast; grilled fish; as a dipping sauce mixed with a small amount of soy sauce.
How spicy is this recipe?
With the specified quantities it is moderately spicy — noticeable heat that builds gradually without being overwhelming. Reduce chili flakes by half for a mild version.
Can I use olive oil instead of neutral oil?
Olive oil has a lower smoke point and its own strong flavor that competes with the chili and garlic. Neutral oil is strongly recommended for this recipe.
Why does the oil look cloudy when refrigerated?
Neutral oils solidify partially when cold, which causes cloudiness. This is completely normal. The oil returns to its clear, liquid state at room temperature.
