These chili garlic noodles are a perfect balance of sweet and savory. They’re the perfect side when you’re craving something bold and spicy. Regular spaghetti serves as the base for a simple chili crisp and garlic oil, and then everything is tossed with a sweet and savory sauce that coats every strand.

Because the sauce is built while the pasta cooks, the dish comes together in about 20 minutes. It’s simple enough to throw together on a weeknight. The noodles make a tasty side dish for just about any Asian main dish. Serve them with sesame pork, Kung Pao chicken, or beef and broccoli. Or replace your regular baked or mashed potatoes and serve them with steaks or roast chicken.

What You’ll Like About This Recipe

• Fast and weeknight-friendly. You can boil the pasta and build the sauce at the same time, so dinner is ready in the time it takes to cook the noodles—no marinating, no long simmering, and no complicated steps.
• Big flavor from a few ingredients. Chili crisp, garlic, green onions, and a trio of pantry sauces give you heat, savoriness, a touch of sweetness, and that nutty sesame finish without a long ingredient list.
• Flexible heat level. The recipe uses a modest amount of chili crisp, but you can easily dial the spice up or down to suit everyone at the table by adding more to individual bowls.
• Great base for add-ins. These noodles are delicious on their own, but they’re also the perfect canvas for leftover chicken, shrimp, tofu, or extra vegetables like snap peas or bell peppers.

Ingredient Notes

• Spaghetti – Thin spaghetti stands in for Asian noodles and works beautifully to catch the sauce. You can swap in linguine, angel hair, or an Asian-style wheat noodle if you prefer.
• Green onions – These add freshness, mild onion flavor, and a pretty garnish. Cooking the white and light green parts in the oil softens their bite, while the reserved dark green slices brighten the finished dish.
• Garlic – Minced and lightly sautéed garlic is a key flavor here. It should turn fragrant but not brown, or it can become bitter.
• Chili crisp – This chili oil condiment brings heat, crunch, and umami. Start with the smaller amount and add more to taste; different brands vary in spiciness.
• Light brown sugar – A spoonful of brown sugar balances the salty sauces and heat, and the slight molasses note adds depth.
• Low-sodium soy sauce – Soy sauce gives the noodles their savory backbone. Low-sodium helps keep the dish from becoming too salty, especially with salted pasta water.
• Oyster sauce – This thick, savory-sweet sauce adds body and restaurant-style flavor. A little goes a long way and helps the sauce cling to the noodles.
• Sesame oil – A drizzle of toasted sesame oil finishes the sauce with a nutty aroma, so add it after the pan is off the heat to preserve its flavor.

Steps to Make Chili Garlic Noodles

1. Bring a large pot of salted water to a boil and cook the spaghetti until just al dente, following the package directions so the noodles stay firm enough to toss with the sauce.
2. While the pasta cooks, heat the vegetable oil in a small skillet over medium heat. Add the sliced green onion whites and light greens, the minced garlic, and the chili crisp, stirring just until everything is sizzling and aromatic.
3. Remove the skillet from the heat and let the mixture cool slightly so the garlic stops cooking. Stir in the brown sugar, soy sauce, oyster sauce, and sesame oil until the sugar dissolves and the sauce is smooth.
4. Reserve a small splash of the starchy pasta water, then drain the spaghetti well and transfer it to a large serving bowl or back into the warm pot.
5. Pour the chili garlic sauce over the hot noodles and toss thoroughly with tongs or two forks until every strand is coated, adding a spoonful of pasta water if needed to loosen the sauce and help it cling.
6. Taste and adjust the seasoning, adding more chili crisp for extra heat or a little more soy sauce for saltiness.
7. Top the noodles with the reserved dark green onion slices and serve immediately while hot.

Pro Tips

• Salt the pasta water generously so the noodles are well seasoned inside and out.
• Watch the garlic closely as it cooks; it should soften and become fragrant but not darken past pale golden.
• Stir the chili crisp before measuring, because the solid, crunchy bits settle at the bottom of the jar—you want an even mix of oil and solids.
• Serve extra chili crisp and soy sauce at the table so everyone can customize their bowl—milder for some, spicier and saltier for others.

Recipe Variations

• Veggie-loaded chili garlic noodles. Toss in quickly sautéed vegetables such as bell peppers, snap peas, shredded carrots, or baby spinach when you combine the noodles and sauce. The vegetables add color, texture, and extra nutrition.
• Vegetarian Option. Replace the oyster sauce with 2 teaspoons of hoisin and 1 teaspoon of soy sauce. If too sweet, thin with a splash of water.
• Shrimp or chicken chili garlic noodles. Top the finished noodles with seared shrimp or thin strips of cooked chicken. The sauce works beautifully with either protein, turning the dish into a heartier main course.
• Noodle swap. Use rice noodles, lo mein noodles, or udon instead of spaghetti. Cook them according to package directions and toss with the same sauce for a more traditional noodle texture.

How to Store

• Refrigerate: Cool leftovers completely, then transfer the noodles and sauce to an airtight container. Refrigerate for up to 3 days, keeping them well covered to prevent drying out.
• Reheat: Rewarm the noodles gently in a skillet over low to medium heat with a splash of water or broth, tossing until hot and loosened. You can also reheat briefly in the microwave, pausing to stir so the noodles heat evenly and don’t dry out.
