Key Ingredients for the Best Chili Oil Recipe
The secret to bold, authentic chili oil starts with quality ingredients. Each element contributes layers of flavor that transform simple oil and chili flakes into something magical.
Choosing Your Chili Flakes
| Chili Flake Type | Flavor Profile | Heat Level | Oil Color Result | Notes |
|---|---|---|---|---|
| Sichuan Chili Flakes | Fruity, slightly smoky | Medium to high | Vibrant deep red | Preferred for authentic flavor |
| Gochugaru (Korean) | Sweet, earthy | Mild to medium | Bright orange-red | Sweeter, less numbing |
| Aleppo Pepper | Fruity, mild heat | Mild | Reddish-orange | Good for subtle flavor |
| Generic Crushed Red Pepper | Sharp, pungent | Variable | Deep red | Less complex, more heat |
Sichuan chili flakes are preferred here for their distinctive fruity flavor, balanced heat, and authentic vibrant red color that makes your chili oil stand out.
Choosing Your Oil
| Oil Type | Smoke Point (°F) | Flavor | Relative Cost |
|---|---|---|---|
| Canola Oil | 400 | Neutral | Low |
| Grapeseed Oil | 420 | Neutral | Medium |
| Avocado Oil | 520 | Neutral | High |
| Soybean Oil | 450 | Neutral | Low |
A neutral oil with a high smoke point is essential to avoid overpowering the chili flakes and aromatics. Canola and grapeseed oils are great affordable options.
The Aromatics (Your Flavor Base)
Whole spices—star anise, cinnamon stick, bay leaves, Sichuan peppercorns—infuse the oil with complex fragrance and warmth. Optional ingredients like black cardamom, cloves, dried sand ginger, garlic, and shallots add extra layers. Using these aromatics carefully balances the chili’s heat and builds depth in the final oil.
How to Make This Authentic Chili Oil Recipe (Step-by-Step)
This chili oil recipe is easier than you think. Follow the process patiently, and you’ll get rich, fragrant oil every time. Watch the detailed 5-7 minute YouTube tutorial embedded below for a visual guide to the steps, including key cues like the shimmer and slow bubbling of the oil and the satisfying sizzle of the chili flakes.
Ingredients
- 1½-3 cups neutral oil ((350-700 ml))
- 5 star anise
- 1 cinnamon stick ((preferably cassia cinnamon))
- 2 bay leaves
- 3 tablespoons Sichuan peppercorns
- 2 black cardamom pods ((optional))
- 4 nuggets dried sand ginger ((optional – about 1 tablespoon))
- 2 teaspoons cloves ((optional))
- 3 cloves garlic ((optional – crushed))
- 1-2 shallots ((optional – halved))
- ¾-1 1/4 cup Sichuan chili flakes ((65-110g))
- 1 – 2 teaspoons salt ((to taste))
Instructions
- Gather your aromatics. Place oil and the selected aromatics into a pot, leaving at least two inches between the oil and the rim. Use 1½ cups of oil for minimum aromatics, up to 3 cups for all.
- Heat gradually over medium heat. Then lower to medium-low or low to keep the oil at about 225-250° F / 110-120° C. Look for small bubbles rising slowly from the aromatics. Adjust heat to avoid darkening or burning. Infuse for 30 minutes to 1 hour. Remove garlic and shallots when browned all over to prevent burning.
- Prepare your chili flakes. Place them in a heatproof bowl. Use ¾ cup for 1½ cups oil or 1¼ cups for 3 cups oil. Adjust to your preference between more oil or more flakes.
- Strain the oil through a fine-mesh strainer or remove the spices first if they are very dark to avoid burning.
- Test your oil temperature on chili flakes. For fresh, moist flakes, heat oil to 325°-350° F / 163-177° C for a perfect sizzle (Mala Market flakes work well at 350° F). For drier flakes, use 250°-275° F / 120°-135° C; for very roasted flakes, closer to 225°-250° F / 110°-120° C. Pour hot oil carefully over chili flakes and stir to evenly distribute the heat. You’ll know it’s right when you smell a “popcorn” scent without burning.
- Stir in salt and let cool. Store in airtight containers in the refrigerator. Always use a clean utensil to prevent spoilage. Properly stored, it lasts up to 6 months.

How to Make Chili Crisp (A Crunchy Variation)
Once your chili oil has cooled slightly, stir in crunchy additions like fried shallots, garlic chips, roasted soybeans, or peanuts. These add texture and an irresistible crunch, turning your chili oil into a chili crisp that’s perfect on rice or noodles.
Adjusting the Spice, Numbing, and Fragrance
- For more heat, add a pinch of a hotter chili powder or extra chili flakes.
- To boost numbing “ma la” sensation, increase the Sichuan peppercorns or let them infuse longer.
- To enhance fragrance, include all optional aromatics like cardamom, cloves, and dried sand ginger.
Storage & Important Food Safety Tips
According to the USDA, oils infused with fresh ingredients like garlic and shallots carry a risk for botulism if not refrigerated properly. Always store your homemade chili oil containing fresh aromatics in the fridge and consume it within a reasonable timeframe to keep it safe and delicious. For additional guidance on safe oil infusions, Penn State Extension offers excellent resources on how to safely infuse oils.

Frequently Asked Questions (FAQ).
Why is my chili oil bitter or burnt-smelling?
This usually happens when the oil temperature is too high or spices burn during infusion. Keep the heat low and watch for gentle bubbling instead of vigorous sizzling.
Why isn’t my oil a vibrant red color?
The color depends on the chili flakes used and frying temperature. Fresh, moist Sichuan flakes at higher temperatures give a brighter red; drier flakes or lower heat yield darker oil.
What is the difference between Chili Oil and Chili Crisp?
Chili oil is infused oil with chili flakes; chili crisp adds crunchy fried ingredients like garlic and shallots for texture.
Can I make this chili oil recipe without the whole spices?
Yes, but whole spices add essential layers of fragrance and depth that significantly enhance the final flavor.
How do I make the chili oil more or less spicy?
Adjust the amount or type of chili flakes and optionally add hotter chili powders to increase heat.
Is it normal for my chili oil to solidify in the fridge?
Yes, some neutral oils can solidify when chilled. It will liquefy again at room temperature.
