Chili oil is one of my favorite condiments to keep on hand. It has a long shelf life, is relatively affordable (a little goes a long way!), and can instantly give any dish a boost in flavor and savoriness. In addition to spicing up these noodles, give it a try drizzled on Vegetable Fried Brown Rice, Easy Zucchini Stir Fry, or this Veggie Chow Mein!

The Ingredients

- Noodles: Any noodles of choice will work. Traditional Sichuan noodle dishes are often made with wheat-based noodles (Mian or Mi Fen), but if you are gluten-free use rice noodles or Banh Pho noodles. You can also use noodles like ramen or udon noodles.
- Extra firm tofu: This type of tofu is best for pan-frying. It’s firm enough to keep it’s shape, yet is moist enough to absorb the flavors in the chili oil. If you’re new to cooking with tofu, make sure to read my Guide to Tofu and learn How to Press Tofu.
- Oil: Any high-heat cooking oil will do. Use avocado oil, vegetable oil, or refined coconut oil.
- Mustard greens: This popular leafy green is commonly used for it’s unique, slightly spicy flavor. If you can’t find it in the produce section of your grocery store, check your local international grocery store.
- Chili oil: Sichuan chili bean paste, or Pixian doubanjiang, is made from fermented fava beans and chili peppers. It’s known for its rich, complex flavor and is a fundamental ingredient in Sichuan dishes. If you have the opportunity to use it, please do! Otherwise, try another chili oil or hot pepper oil (a homemade chili oil would work great!).
Add-ins and Substitutions
- Aromatics: If you’d like to increase the flavor in this noodle dish, add fresh garlic, grated ginger, and sautéed shallot.
- Make these noodles saucier: If your chili oil is thick, add a few splashes of vegetable broth to loosen it up and make it extra saucy.
- Add veggies: Bulk up these spicy noodles with your favorite stir-fry vegetables.
How to Make Chili Oil Noodles
- 1) First, prepare your noodles. Bring a large pot of water to a boil, then cook the noodles according to package instructions.
- 2) Next, heat a skillet over medium-high heat. Once hot, add your neutral oil of choice and allow to heat for a few minutes. Add the tofu to the hot oil and sear until golden brown, or as desired. After a few minutes, add the chili oil and toss to combine.


- 3) While the tofu cooks, in a separate small pot, bring a cup of water to a boil. Once boiling, add the mustard greens and simmer until the greens are bright green. Drain and set aside.
- 4) When the tofu has about 30 seconds left to cook, add the drained mustard greens to the skillet and stir to combine. Add the black pepper and stir again, sautéing for 30 to 60 more seconds.

- 5) Add the cooked noodles, then stir and heat together, until thoroughly mixed and heated.


- 6) Serve immediately while warm!
Recipe FAQs
It is believed that chili oil noodles originated from Sichuan cuisine.
The spice in this noodle recipe comes entirely from the amount of chili oil used. If you are sensitive to spice, start with just a couple of teaspoons and increase from there. For spice lovers, a few tablespoons may be preferred!
Most noodle dishes are best fresh, but these noodles can be made for meal prep, if desired. Make the recipe as instructed, then allow to cool to room temperature. Transfer the chili oil noodles and tofu between individual serving containers and refrigerate for up to 3 days. When ready to eat, reheat in the microwave or toss in a large skillet or wok until warmed through and crispy again.
Top Recipe Tips
- Use a wok or cast iron skillet. I love my non-stick skillet, but my cast iron does a lot better at making tofu and noodle dishes extra crispy. Or, if you happen to have one, use a wok!
- Be careful not to overcook the noodles. Like spaghetti and Italian pasta, these noodles are easy to overcook and will become grainy and mushy. Make sure to read the package directions for your type of noodles and be careful not to over-do it.
- Repurpose the remaining mustard greens. I like to make these noodles with mustard green stems, but if you prefer, you can add in the stems and leaves. Or, sauté the leftover greens and serve them as a nutritious side dish.

Serving Suggestions
Serve these spicy, hot noodles with extra chili oil sauce and easy side dishes like Baby Bok Choy with Soy Sauce and Garlic, Tofu Vegetable Crispy Wontons, or Sautéed Eggplant!
