Spicy Asian Noodle Soup Ingredients
Here are a few quick notes about the ingredients you will need to make this spicy Asian soup recipe:
- Sesame oil: I like using this as the cooking oil in this recipe, because it has a toasted, nutty taste that enhances the rest of the flavors in this soup.
- Yellow onion: This single ingredient adds so much complexity and depth of flavor to the broth. Don’t skip it!
- Garlic and ginger: These two aromatics are non-negotiable in Asian cooking. Always use freshly grated/minced garlic and ginger for best results.
- Vegetable stock: This will serve as the base for the soup broth. If you’re not vegetarian or vegan, chicken broth can be used instead.
- Soy sauce: This condiment adds salty and savory flavor to the broth. If you are gluten-intolerant, then you can use tamari (gluten-free soy sauce) instead. I recommend always purchasing high-quality organic soy sauce and tamari. Soybeans are one of the top GMO and pesticide-laden crops, so it’s worth spending the extra money on organic.
- Sriracha: This spicy sauce adds a good amount of heat without overpowering the rest of the flavors in the dish.
- Rice vinegar: A splash of this type of vinegar adds a bit of much-needed acidity to the broth. In addition, it balances the rest of the flavors in the soup.
- Noodles: I use thin rice noodles when making this soup recipe. I love them because they only take a few minutes to cook.
- Chopped fresh cilantro, green onions, and sesame seeds: These garnishes are completely optional, but I recommend using them because they give the soup a huge burst of freshness and texture, as well as a nice bright pop of color.

How to Make Spicy Asian Noodle Soup
Alright, here is a brief overview of how to make Asian noodle soup:
- Cook the aromatics: Sauté the onion, garlic, and ginger and in a bit of sesame oil until softened and fragrant.
- Add the liquids: Stir in the broth and water and bring to a boil.
- Stir in the flavorings: Add the soy sauce, Sriracha, and rice vinegar.
- Cook the noodles: Add the rice noodles to the pot and leave them to sit in the broth until tender.
- Garnish and serve: Top your soup with the optional garnishes (if using) and serve it up nice and hot.
Detailed instructions are included in the recipe below, as always.
How Prevent Noodles from Getting Soggy in Soup
For best results, only let the noodles cook in the broth for a few minutes (just until they are softened) and then serve the soup right away. I find that if the noodles sit in the soup for too long after I make it, they tend to absorb a lot of the liquid and get very mushy.
Possible Recipe Variations
Want to customize this Asian spicy soup recipe a bit? Feel free to…
- Add protein: You could add thinly sliced beef steak, shrimp, tofu, or shredded chicken to make the soup even heartier and more satiating.
- Make it milder: If you don’t like much heat in your food, I would recommend using half the amount of Sriracha the recipe calls for.
- Make it spicier: If you do like a lot of heat in your food, feel free to add more Sriracha and/or a few pinches of crushed red pepper flakes.
- Add veggies: You’re welcome to add in whatever vegetables you might love in a soup. If you would like to save a step, you could also just add in a bag of a pre-chopped frozen stir-fry veggie mix.
Those are just some common variations for noodle soup. However, your options for customizing it are truly endless, so feel free to get creative!
