What makes this sauce so great is its versatility. It’s incredibly simple—perfect for a quick meal or a late-night fix. Use it as is, or mix in extras like vegetables and shredded chicken, tofu, or cooked shrimp for protein. But let’s be real—the chili oil is the star. It delivers a warm, lingering heat that never overpowers, balanced by the deep, aromatic punch of garlic.

Ingredients You Need

The ingredients are simple, but each one plays a key role in making this dish shine. Check How to Stock Your Noodle Pantry for details on these ingredients. Here’s what you’ll need:

• Noodles: You can use just about any type of noodle here—just use what you have on hand, whether that’s fresh udon noodles, dried spaghetti, or something else entirely. You could use rice noodles if you want it to be gluten-free.
• Chili oil: The star of the show, chili oil brings heat, depth, and a hit of umami. You can use store-bought chili oil or make your own by simmering chili flakes, like gochugaru, in a neutral oil, like avocado oil, if you want to control the spice level.
• Garlic cloves: Minced fresh garlic adds an aromatic punch that ties everything together. Don’t skip it—jarred garlic won’t have the same bite.
• Green onions: The white and pale green parts bring a mild onion flavor that balances the richness of the chili oil. You’ll also want a few extra for garnish.
• Rice vinegar: A little acidity brightens up the sauce. You can use regular rice vinegar or Chinese black vinegar. If you don’t have rice vinegar, apple cider vinegar will work in a pinch.
• Sugar: Just a touch helps round out the flavors and keeps the heat in check.
• Soy sauce: The backbone of the sauce. It brings saltiness and deep umami flavor that pulls everything together.
• Toasted sesame oil: A few drops of this nutty, aromatic oil add richness and depth. Make sure you’re using the toasted variety—it makes all the difference.
• Sesame seeds: These add crunch and a little extra nuttiness. If you have toasted sesame seeds, even better.
• Extra green onions: A sprinkle on top adds freshness and a pop of color.

How to Make It

This is where the Garlic Chili Oil Sauce magic happens, and it’s super easy:

1. Heat the chili oil: In a small saucepan over medium-low heat, gently warm the chili oil. You want it hot but not smoking.
2. Cook the garlic and green onions: Add the minced garlic and finely chopped green onions to the hot oil. Let them cook for a minute or two until fragrant.
3. Mix in the rest: Remove the pan from heat and stir in the remaining minced green onions, toasted sesame oil, and sesame seeds.
4. Toss with noodles: Add the cooked noodles back into the pot you used to cook them. Pour the sauce mixture over the noodles and toss until they’re completely coated. Portion into bowls and serve hot.

What Noodles to Use with Garlic Chili Oil Sauce?

Take a look at A Beginner’s Guide to Asian Noodles for a primer on various noodle options. Almost any noodle will work with this sauce, but fresh udon is my top pick for its satisfyingly chewy texture. Chinese wheat noodles, knife-cut noodles (sometimes called “squiggly” noodles), and fresh ramen (not the instant kind) all soak up the flavors beautifully. Even spaghetti can do the trick if that’s what you have on hand.
