Ingredient Notes

All the ingredients needed for making a garlic chili oil noodle recipe with miso paste, green onion, sesame seeds and soy sauce. Each ingredient is labelled with text.
  • Oil: You’ll need a neutral oil like avocado oil or grapeseed oil. I used grapeseed oil.
  • Garlic: Use fresh/raw garlic cloves.
  • Red Chili Flakes: You can use red chili flakes (red pepper flakes), Korean chili flakes or Szechwan chili flakes. The recipe calls for 1 tbsp but you can increase it for extra spice.
  • Miso Paste: You can use any variety of miso paste. White or yellow miso paste is milder in flavour while dark or red miso paste has a stronger flavour.
  • Sesame Seeds: You can purchase toasted sesame seeds or toast your own in a dry pan on the stovetop over low heat until they’re lightly browned.
  • Noodles: You can use flat wheat noodles, ramen, udon or for a gluten-free option, rice noodles.
  • Green Onion: You’ll need 1 small bunch or about 6-8 green onions (scallions/spring onions).
  • Soy Sauce: You can use regular soy sauce, dark soy sauce or for a gluten-free option, tamari or coconut aminos.
  • Rice Vinegar: Seasoned or unseasoned rice wine vinegar works.
  • Sugar: Use brown sugar or coconut sugar or substitute maple syrup.

This list is not complete. Please see the recipe card at the end of the post for the complete ingredient list with measurements and detailed instructions.

Additions

  • Serve with Crispy Baked Tofu or other protein of choice.
  • Mix in cooked, shelled edamame.
  • To add more vegetables, stir fry them in the chili garlic oil until tender before adding the scallions, noodles and sauce. You could also stir fry them separately and serve them on top of the noodles.
  • Vegetables that work well are broccoli, mushrooms, carrot, bok choy, snap or snow peas or cabbage. Keep it simple by choosing 2-3 cups of 1-2 veggie add-ins.

Step-by-Step Instructions

Step 1: Make the Garlic Chili Oil

A hand stirring chopped garlic, shallot and chili flakes cooking in oil with a wooden spoon in a small pot.

In a small saucepan, heat the oil, garlic, shallot, chili flakes and salt over low heat. Cook the mixture for 3-5 minutes, stirring occasionally until the oil is warm and garlic is fragrant.

Quick Tip: Be sure to keep an eye on it to avoid burning the garlic which will make the oil bitter. When you see small bubbles forming in the oil, remove it from the heat.

Recipe FAQs

What kind of noodles should I use for this recipe?

You can use any type of noodles you like. Flat or wide wheat noodles are suggested but ramen noodles, udon noodles or even just spaghetti or linguini noodles work too. If you can find fresh noodles in an Asian grocery store, even better.

If you need the recipe to be gluten-free, you can use rice noodles (be sure to use gluten-free tamari instead of soy sauce as well).

Can I make the garlic chili oil ahead of time?

Absolutely! The chili oil can be made in advanced and stored in an airtight container in the fridge for up to 1 month. In fact, making it ahead of time will give it even more time for the flavours to infuse the oil.

You can even just make it an hour or two ahead to allow extra time for infusion before using it in the recipe.

If it’s been stored in the fridge, just make sure you let it come to room temperature before adding it to a hot pan.

Can I add vegetables or protein to the recipe?

For sure! This recipe is easy to customize with extra veggies like bell peppers, bok choy, carrot, broccoli or cabbage or by adding a protein like crispy tofu or tempeh.

How spicy are chili garlic noodles?

I can’t eat very spicy food and these noodles are fine for me. There’s some heat but it’s not overpowering.

You can also adjust the level of of spiciness but using more or less chili flakes than is listed in the recipe.

Storing Leftovers

  • Store leftover noodles in an airtight container in the fridge for 3-4 days.
  • If the noodles are dry after storing, you can add a splash or water or broth to loosen them.
  • Reheat the noodles in a pan on the stovetop or in the microwave until heated through. You can also enjoy leftover cold noodles.
  • Chili oil noodles are not ideal for freezing.

Ingredients

For the Chili Garlic Oil

  • cup neutral oil like avocado or grape seed
  • 3 cloves garlic minced or grated
  • 1 shallot finely chopped
  • 1 tbsp chili flakes regular, Korean gochugaru or szechuan chili
  • ½ tsp sea salt
  • 1 tbsp toasted sesame seeds
  • 1 tsp miso paste
  • 1 tsp sesame oil

For the Noodles

  • 8 oz flat wheat noodles
  • 6 green onions thinly sliced
  • 3 tbsp soy sauce or tamari
  • 2 tsp rice vinegar
  • 2 tsp brown sugar or coconut sugar

Instructions

  • Prepare: Mince the garlic and finely the chop the shallot and green onion. If you don’t have toasted sesame seeds, you can toast your own by adding the 1 tbsp seeds to a dry pan and toasting over low heat for 5-7 minutes until golden brown. You can do this at the same time as cooking the chili oil.
  • Make the Chili-Garlic Oil: In a small pot, heat oil, garlic, shallot, chili flakes and salt over low heat.
  • Cook for 3-5 min, stirring occasionally, until oil is warm and garlic is fragrant. Keep an eye on it so it does not burn.  If the garlic burns, it will become bitter. When you start to see little bubbles forming in the oil, it is done. Remove the pot from the heat, then stir in sesame seeds, sesame oil and miso. Set aside to infuse. 
  • Cook Noodles: In a large pot, cook noodles according to package instructions. Drain noodles.
  • Mix Sauce: While the noodles are cooking, in a small bowl, stir together soy sauce, rice vinegar and sugar. 
  • Finish Noodles: In a large non-stick pan, heat 4 tbsp of the chili-garlic oil over medium heat. Add three quarters of the green onions, cooked noodles and soy mixture. Using tongs, toss to coat noodles, cooking for 1 min to warm through. 
  • Serve: Divide noodles between bowls. Sprinkle with remaining green onions, and sesame seeds, if desired. Drizzle more chili-garlic oil. Servings Suggestions: Top with roasted broccoli & crispy tofu.
