There are many ways to make chili oil for your homemade Biang Biang noodles. We’re starting with two simple recipes that deliver distinct, satisfying flavors. Both are easy to follow, so you can elevate your noodle game in no time.
Recipe 1: Classic Chili Oil for Biang Biang Noodles
A vibrant, aromatic chili oil is the star seasoning that brings Biang Biang noodles to life. The key to great flavor lies in choosing the right chili powder and mastering the hot oil-pouring technique. Here’s how to make a classic version at home.
Ingredients You’ll Need
Chili powder: Shaanxi-produced chili powder is highly recommended for its perfect balance of heat and aroma. You’ll need about 2 tablespoons (10g).
Aromatics & Seasonings: 1 tablespoon each of minced green onions, minced garlic, and minced ginger; a handful of roasted, chopped peanuts; 2 tablespoons light soy sauce; 1 tablespoon mature vinegar (such as Chinese black vinegar); 1 tablespoon sesame oil.
Oil: About 2 tablespoons (30ml) of a neutral oil, like peanut or canola oil, per serving.
Key Tips for Pouring the Hot Oil
Control the Temperature: Heat the oil until it just begins to smoke, around 400°F (200°C). Avoid overheating, as this can burn the chili powder and create a bitter taste.
Pour in Batches: First, pour a small amount of hot oil over the chili powder to gently wake up its aroma. Then, add the remaining oil in batches. This technique prevents burning and ensures the spices heat evenly.
Adjust to Taste: Use about 2 tablespoons of oil per bowl of noodles, adjusting the amount based on your preferred spice level.
Step-by-Step Instructions
Cook your Biang Biang noodles according to the package directions until tender. Drain them and set aside. You can add toppings like bean sprouts or spinach to the noodles at this stage.
In your serving bowl, combine the chili powder, minced green onions, garlic, ginger, a pinch of salt, light soy sauce, mature vinegar, and sesame oil.
Heat the oil in a small saucepan or wok until it shimmers and just begins to smoke.
Carefully pour the hot oil evenly over the seasonings in the bowl in two or three stages. You should hear a satisfying sizzle as the aromas are released.
Add the cooked Biang Biang noodles to the bowl and toss thoroughly until every strand is coated in the spicy chili oil. Serve immediately.
Recipe 2: Homemade Biang Biang Noodles with Chili Oil (Full Recipe)
This complete recipe guides you through making both the noodles and the chili oil from scratch. The result is incredibly chewy, wide ribbons of pasta tossed in a deeply fragrant and spicy sauce.
Ingredients You’ll Need
For the Noodles: 4 cups (500g) all-purpose flour (high-gluten flour is ideal for chewiness), 1 teaspoon (5g) salt, about 1 cup + 1 tablespoon (260ml) water.
For Toppings & Chili Oil: Mung bean sprouts, baby bok choy, garlic, green onions, rapeseed or canola oil, salt, light soy sauce, mature vinegar, Sichuan pepper powder, dried chili flakes or segments.
Step-by-Step Instructions
Make the Dough: In a large bowl, mix the flour and salt. Gradually add the water while stirring until a shaggy dough forms. Knead for a few minutes into a rough ball, cover, and let it rest for 10 minutes. Knead again until smooth and elastic.
Rest the Dough: Divide the smooth dough into equal portions. Brush each portion lightly with oil, cover, and let it rest for at least 1 hour (2 hours is ideal). This resting period is crucial—it relaxes the gluten, making the dough incredibly easy to stretch.
Shape the Noodles: After resting, take one portion and press it flat into a long strip. Use a chopstick or the back of a knife to press a deep line down the center.
Pull the Noodles: Hold both ends of the dough strip and gently slap and stretch it against the countertop. You’ll hear the distinctive “biang biang” sound that gives these noodles their name! Stretch it to about half a meter long. For the classic wide shape, tear the strip apart along the pressed line.
Cook the Noodles: Bring a large pot of water to a rolling boil. Add the noodles and cook. When the water returns to a boil, add a splash of cold water. Once the noodles float to the surface, they are done. Drain them (rinsing with cold water is optional for a chewier bite).
Prepare the Veggies: Briefly blanch the bok choy and bean sprouts in the boiling water for about 30 seconds, then drain.
Make the Chili Topping: In a dry pan, lightly toast the dried chili flakes or segments until fragrant. Let them cool, then crush them into small pieces if using segments. Mince the garlic and green onions.
Assemble the Dish: Place the cooked Biang Biang noodles and blanched veggies in a bowl. Top with light soy sauce, mature vinegar, Sichuan pepper powder, the crushed chilies, and minced garlic.
The Final Sizzle: Heat the oil until it’s very hot and shimmers. Carefully pour the sizzling oil over the toppings—this will release an incredible aroma. Sprinkle with minced green onions, toss everything together, and enjoy!
This from-scratch version is incredibly flavorful and satisfying. Even if you don’t have every single ingredient, simply tossing the freshly made noodles with chili oil and minced garlic is a delicious triumph.
