Easy Fragrant Garlic Chili Oil Recipe with Sichuan Chili Flakes

This chili oil recipe makes a sizzling, glossy jar of garlicky Sichuan heat in just 25 minutes. Spoon it over tacos, noodles and rice tonight.
This chili oil recipe gives you a sizzling, glossy ruby-red jar of fragrant garlicky heat in just 25 minutes. No fancy gear, just one small pot, and it's ready for taco night, noodles, or Sunday cookouts.
Why This Recipe Works
• Mince garlic into tiny, even crumbs: Uniform bits fry at the same rate, so every piece turns sweet and golden together. Larger chunks scorch on the outside and turn bitter before they cook through.
• Keep the oil at 250°F: This gentle heat coaxes out the garlic's fragrance without burning it. Hotter oil browns garlic in seconds, and it turns acrid.
• Pour the hot oil over the flakes: The sizzle blooms the Sichuan chili flakes instantly and pulls their color and toasty aroma into the oil. Pouring over the flakes, instead of frying them in the pan, keeps them from blackening.
• Rest the oil before you jar it: As it cools, the chili and garlic keep soaking into the peanut oil. The flavor gets rounder, deeper, and more fragrant with every minute.
Ingredients You'll Need
Peanut Oil: This is the golden backbone of the whole jar. Its mild, nutty flavor lets the chili and garlic shine, and it handles 250°F without breaking a sweat. No peanut oil? Grab avocado or canola oil for a clean, neutral swap.
Sichuan Chili Flakes: These coarse, brick-red flakes bring gentle heat and a deep toasty aroma. They're the reason your oil turns that glossy ruby red when the hot oil hits. Crushed red pepper flakes work great in a pinch, though they run a bit spicier.
Garlic: Six peeled cloves, minced into tiny sticky crumbs, give this oil its sweet, fragrant soul. Fried pale golden, they turn crunchy and mellow instead of sharp. Out of garlic? Finely minced shallot gives a softer, sweeter crunch.
How to Make It (Step by Step)
This all happens in one small pot and one heatproof bowl: gently fry the garlic until golden, pour the sizzling oil over the chili flakes, then let it cool into a glossy ruby jar.
Even if you've never made chili oil before, you'll nail it, and your kitchen will smell like a party.
- Mince the peeled garlic as fine as you can until the pieces look like tiny, sticky crumbs, 3-5 minutes at room temperature (70°F / 21°C). Small bits fry evenly. Big chunks burn and turn bitter, and nobody wants that.
- Spoon the Sichuan chili flakes into a deep heatproof bowl until they sit in a loose, even layer, about 1 minute at room temperature (70°F / 21°C). Pick a bowl with tall sides. The oil foams up fast later.
- Heat the peanut oil in a small saucepan over medium-low until it shimmers and ripples, 3-4 minutes at 250°F / 120°C. Clip on a thermometer if you have one. It takes the guesswork away.
- Add the minced garlic and stir gently until it smells sweet and turns pale golden, 4-6 minutes at 250°F / 120°C. Watch it closely. Golden is perfect, brown is too far.
- Pour the hot oil and garlic slowly over the chili flakes until the whole bowl sizzles and foams, 20-30 seconds at 250°F / 120°C. Listen to that crackle. Your kitchen will smell incredible right now.
- Stir everything together until the oil turns a glossy, deep ruby red, 1-2 minutes at 225°F / 107°C. Scrape the bottom so no flakes clump. Every spoonful should look evenly speckled.
- Let the chili oil cool on the counter until the bowl feels cool to the touch, 30-45 minutes at room temperature (70°F / 21°C). The flavor deepens as it rests. Sneak a taste, I won't tell.
- Spoon the oil, flakes and garlic into a clean glass jar until it's filled almost to the top, 2-3 minutes at room temperature (70°F / 21°C). Seal it tight. Now it's ready for tacos, noodles and everything in between.
Refrigerate your chili oil sealed for up to one week, letting it sit out 15 minutes before using. Crushed red pepper subs fine for Sichuan flakes, and always scoop with a dry spoon.

Tips and Tricks
- Equipment: Use a small saucepan and a clip-on thermometer: A small pot keeps the peanut oil deep enough to fry the garlic evenly. The clipped thermometer shows exactly when you hit 250°F. No guessing, no scorched batches.
- Temperature precision: Hold the oil right at 250°F: Above 275°F, garlic flips from golden to bitter in seconds. Nudge the burner down if the oil starts to smoke. Gentle heat keeps every crumb sweet and fragrant.
- Common mistake: Dumping the hot oil in one rush: Pouring too fast makes the bowl foam over, and the flakes on top never bloom. Pour in a slow, steady stream. Let that crackle wash over every flake.
- Flavour upgrade: Stir in crushed roasted peanuts: Once the oil cools, fold in a small handful of chopped roasted peanuts. They echo the peanut oil and add a toasty, nutty crunch. Hello, peanut chili oil.
- Texture tip: Scrape the bottom while you stir: Flakes love to settle and clump into a wet paste. Drag your spoon along the bottom until the oil looks glossy and evenly speckled. Every spoonful gets crispy garlic and chili.
Frequently Asked Questions
Can I make this chili oil without peanut oil for a peanut allergy?
Yes, swap the 1 cup peanut oil for 1 cup avocado, canola, or grapeseed oil, since all three handle 250°F easily and keep the chili and garlic flavor front and center. Skip extra virgin olive oil, because its strong, grassy taste fights the chili and garlic.
Can I freeze homemade chili oil to make big batches ahead of time?
Yes, portion the cooled chili oil into an ice cube tray, then move the cubes to a freezer bag for up to 3 months. Thaw cubes overnight in the fridge, or warm one in a small saucepan over low heat for 1-2 minutes until it loosens and smells fragrant.
Why did my chili oil turn dark brown and taste bitter instead of ruby red?
The oil was too hot when it hit the flakes, so pull the pan off the heat and let it drop to 250°F, checking that a single flake sizzles gently rather than blackening on contact. If your garlic browned past pale golden in the pot, strain it out and start that batch over.
What to Serve With This
- Smashed Cucumber Salad: Cold, crunchy cucumbers in a tangy rice vinegar dressing cool the fiery chili oil and cut its richness.
- Steamed Jasmine Rice: Fluffy, fragrant rice soaks up every glossy red drop and softens the heat into a cozy, mellow bite.
- Garlicky Sautéed Baby Bok Choy: Tender stems and bright green leaves bring a fresh, juicy crunch that balances the toasty chili flakes.
- Avocado Slices with Lime: Buttery avocado and a sharp squeeze of lime tame the burn with creamy, zesty relief.
