• Easy technique: No special tools required.Just a pot, a bowl, and a strainer.
• Fully customizable: Choose your chilies, oil, aromatics, and extra seasonings to match your style.
• Long-lasting: Stored properly, it keeps for weeks and stays bright and flavorful.
• Versatile: Drizzle on noodles, dumplings, pizza, soups, eggs, veggies, or use it in marinades and dressings.

Ingredients

• Neutral oil (2 cups): Canola, grapeseed, peanut, or vegetable oil.
• Crushed red pepper flakes (1/2 cup): Or use a mix of Sichuan chili flakes and Korean gochugaru for color and warmth.
• Garlic (6–8 cloves), thinly sliced.
• Ginger (1-inch piece), sliced.
• Scallions (2–3), white parts only, roughly chopped.
• Whole spices (optional but recommended): 2 star anise, 1 cinnamon stick, 2 bay leaves, 1 teaspoon coriander seeds.
• Sichuan peppercorns (1–2 teaspoons), lightly crushed (optional for numbing citrusy notes).
• Soy sauce (1 tablespoon) or salt (1–1.5 teaspoons), to taste.
• Sugar (1 teaspoon) or honey (1 teaspoon), optional for balance.
• Sesame seeds (1 tablespoon), optional for texture.
• Rice vinegar (1 teaspoon), optional for a touch of brightness.

Instructions

1. Set up your chili base: In a heatproof bowl, combine chili flakes, Sichuan peppercorns (if using), sesame seeds, and sugar. Place the bowl on a stable surface. Keep a fine mesh strainer nearby.
2. Infuse the oil: Add oil to a small pot.Add garlic, ginger, scallions, star anise, cinnamon stick, bay leaves, and coriander seeds. Heat on low to medium-low. You want a gentle sizzle, not a fry.

   Stir occasionally.

3. Watch the aromatics: After 10–15 minutes, the garlic should be lightly golden and fragrant, not brown. If anything darkens too fast, lower the heat. This slow infusion builds flavor without bitterness.
4. Test the temperature: Aim for around 225–250°F (107–121°C).If you don’t have a thermometer, drop a chili flake in the oil. It should bubble steadily but not burn.
5. Strain the oil: Turn off the heat. Carefully pour the hot oil through the strainer into the bowl of chili flakes.Do this in two stages: pour about half first, stir, then pour the rest. The first pour “blooms” the chilies; the second deepens the color and flavor.
6. Season: Stir in soy sauce or salt. Add rice vinegar if you like a tiny lift.Taste carefully once cool enough and adjust salt and sugar as needed.
7. Cool and store: Let the chili oil cool to room temperature. Transfer to a clean, dry jar with a tight lid. The solids should be submerged in oil.
8. Rest before using: For best flavor, wait at least 12 hours.It’s good right away, but it gets even better the next day.

Keeping It Fresh

• Storage: Keep in a clean, airtight jar. Store at room temperature for up to 2 weeks, or in the refrigerator for up to a month or more.
• Moisture is the enemy: Always use a clean, dry spoon. Avoid introducing water, which can shorten shelf life.
• Submerge solids: Make sure the chili flakes and aromatics are covered by oil to prevent oxidation and off flavors.
• Refrigeration note: Oil may solidify in the fridge.That’s normal. Let it sit at room temperature or warm the jar slightly to loosen.

Benefits of This Recipe

• Affordable: Uses pantry staples and makes a large batch for a fraction of store-bought prices.
• Custom heat level: Blend chili flakes to control spice and flavor complexity.
• Better ingredients: Choose high-quality oil and spices, and skip unwanted additives.
• Meal shortcut: Instantly boosts simple dishes—perfect for busy days.
• Gifting: Poured into small jars, it makes a great homemade gift.

Common Mistakes to Avoid

• Overheating the oil: If the aromatics brown too fast, the oil will taste bitter. Keep the heat low and steady.
• Skipping the strain: Leaving all the aromatics in can lead to burnt bits and shorter shelf life.Infuse, then strain.
• Using only one chili: A blend creates better flavor and color. Combine standard red pepper flakes with gochugaru or Sichuan flakes if possible.
• Under-seasoning: A pinch of salt or a splash of soy sauce brings everything together. Don’t be afraid to adjust.
• Not letting it rest: The flavor improves dramatically overnight.Give it time if you can.

Variations You Can Try

• Garlic-forward: Add extra thin-sliced garlic. Fry gently until pale gold, strain, and fold some chips back into the finished oil.
• Smoky: Add a pinch of smoked paprika or use a touch of smoked chili flakes.
• Citrus twist: Add strips of orange peel during infusion. Remove before pouring over chilies.
• Umami bomb: Stir in a teaspoon of mushroom powder, a splash of fish sauce, or a spoonful of black vinegar after cooling slightly.
• Nutty: Swap 2–3 tablespoons of the neutral oil for toasted sesame oil after straining for a deep, nutty aroma.
• Mala style: Increase Sichuan peppercorns to 2 teaspoons and add a few dried chilies to the infusion for extra numbing heat.

FAQ

How spicy is this chili oil?

It’s medium by default.

Use milder flakes like gochugaru for a gentler heat or add hotter flakes like Thai or Kashmiri chili to crank it up. You can always blend different chilies to land exactly where you want.

Can I use olive oil?

You can, but use a light or extra-light olive oil. Strong extra-virgin flavors can clash with the spices when heated.

Neutral oils keep the focus on the chili and aromatics.

Do I have to use Sichuan peppercorns?

No. They’re optional but add a unique citrusy, tingling note that pairs beautifully with chili heat. If you skip them, the oil will still be delicious—just more straightforward.

What if I don’t have a thermometer?

Watch the aromatics and use the bubble test.

You want gentle bubbling around the garlic and ginger, not vigorous frying. A test flake should fizz softly without darkening immediately.

How long does it last?

At room temperature, about 2 weeks if kept clean and dry. In the fridge, a month or longer.

Always keep the solids covered with oil and use a dry spoon to extend freshness.

Can I add fresh herbs?

Avoid leaving fresh herbs in the finished jar. If you want herbal notes, add them during the oil infusion and strain them out. This keeps the oil clean and stable.

Why is my chili oil bitter?

Likely from overheated aromatics or scorched chili flakes.

Next time, lower the heat, watch for pale gold on the garlic, and pour the oil in two stages to control blooming.
