I’m sharing an Asian Chicken Noodle Soup that hides a pantry-friendly umami trick and a sneaky slow cooker shortcut you won’t expect.

Jump to Recipe

I love how this Slow Cooker Asian Chicken Noodle Soup sneaks up on you. I tossed in chicken thighs or breasts and let the slow cooker do its thing, then add rice noodles at the end so they dont turn to mush.

The broth hits savory and bright notes you won’t expect, and every spoonful makes you want to know what the secret was. I started calling it my Easy Asian Inspired Crockpot Soup and a couple friends already declared it the Best Slow Cooker Chicken Noodle Soup.

It’s simple but not boring, and I promise you’ll slurp before you decide whether to share.

How to Make this

Print Recipe (No Advertisments)

1. Prep everything: slice carrots, mushrooms and onion, mince garlic and ginger, slice scallions, chop cilantro and cut lime wedges. Measure out broth, soy sauce, sesame oil, rice vinegar, honey, fish sauce and red pepper flakes so you’re ready.

2. Optional but recommended: heat 1 tablespoon sesame oil in a skillet and quickly brown the chicken 1 to 2 minutes per side just to get color. In the same pan toss in the onion and mushrooms and cook until they start to brown, then add garlic and ginger for 30 seconds. This adds real depth, but you can skip it and go straight to the slow cooker.

3. Add the chicken, carrots, browned onion and mushrooms (or raw if you skipped the pan), garlic and ginger to the slow cooker. Pour in 8 cups low sodium chicken broth, 1/4 cup low sodium soy sauce, 2 tablespoons rice vinegar, 1 tablespoon honey or brown sugar, 1 to 2 teaspoons fish sauce if using, and 1/4 to 1/2 teaspoon crushed red pepper flakes. Season lightly with salt and black pepper.

4. Cook on LOW for 6 to 7 hours or HIGH for 3 to 4 hours, until the chicken is very tender and easy to shred.

5. Remove the chicken to a cutting board, shred with two forks, then return the shredded chicken to the slow cooker. Taste the broth and adjust seasoning with more soy sauce, fish sauce, salt, pepper or a pinch more sugar if needed.

6. If you want a slightly thicker broth mix 1 tablespoon cornstarch with 1 tablespoon cold water until smooth, stir into a cup of hot broth taken from the cooker, then pour it back in and set slow cooker to HIGH for 8 to 10 minutes until it thickens slightly.

7. Noodle time: rice noodles can go mushy in the slow cooker so either cook 6 to 8 oz dried rice noodles separately according to package directions and add to bowls, or if using ramen noodles add them to the slow cooker in the last 5 to 7 minutes so they just soften. Do not leave dried rice noodles in the pot for hours.

8. Stir in 3 cups baby spinach or 2 cups shredded bok choy and the sliced scallions, let wilt for a minute or two. Adjust heat and acid with fresh lime juice to brighten it up.

9. Serve hot over noodles if you cooked them separately, garnish with extra scallions, cilantro and lime wedges. Add extra crushed red pepper if you like it spicy. Enjoy.

FAQ

Q: Can I use chicken breasts instead of thighs and will the cooking time change?

A: Yes, you can. Thighs stay juicier and forgive overcooking better, breasts work fine but can dry out if left too long. Cook on low 6 to 7 hours or high 3 to 4 hours, shred and check doneness early if using breasts.

Q: When should I add the noodles so they dont get mushy?

A: Dried rice or ramen noodles get soggy if cooked all day. Either cook them separately and add to bowls when serving, or stir them into the hot soup 5 to 10 minutes before serving for firmer texture. Fresh noodles only need a couple minutes at the end.

Q: Do I need the fish sauce and how much salt should I add?

A: Fish sauce adds umami and depth, its optional but recommended 1 to 2 teaspoons. Because fish sauce and soy are salty, taste near the end and add extra salt sparingly. Start with no extra salt, then adjust.

Q: How do I thicken the broth a little without messing up the flavor?

A: Mix the cornstarch with cold water to make a slurry and stir into the soup in the last 10 to 15 minutes on high, or after you shred the chicken. Heat until it slightly thickens, dont overdo it, you just want a light body not gravy.

Q: Can I make this ahead, freeze it, or store leftovers?

A: Store in the fridge 3 to 4 days. For freezing remove any cooked noodles and spinach, freeze the broth and chicken up to 3 months. Thaw in refrigerator and reheat gently, then add fresh noodles and greens when serving.

Q: Any easy swaps for gluten free or vegetarian options?

A: Use tamari or coconut aminos for gluten free. For vegetarian swap chicken for firm tofu, use vegetable broth and skip fish sauce or use a vegan umami boost like miso or mushroom powder. Veggies can be boosted with bok choy, napa cabbage or extra mushrooms.

Slow Cooker Asian Chicken Noodle Soup Recipe Substitutions and Variations

Chicken: swap for extra firm tofu, pressed and cubed for a veg version, or use shredded rotisserie chicken to save time
Soy sauce: use tamari if you need gluten free, or coconut aminos for a slightly sweeter, milder flavor
Rice noodles: try dried ramen, udon, or glass noodles (mung bean) instead, just watch cooking times so they dont go mushy
Fish sauce: replace with 1 tsp soy sauce plus 1/4 tsp Worcestershire, or stir in a little miso paste or a few torn pieces of dried seaweed for umami

Pro Tips

1. Brown the chicken and veg first if you have time — it really deepens the flavor. Use high heat, don’t crowd the pan, just a quick sear for color and you’ll notice the broth tastes way richer after shredding the meat.

2. Handle the noodles separately. Rice noodles get gummy if they sit in the pot so cook and rinse them cold, toss with a tiny splash of oil so they dont clump, then add to bowls. If you use ramen, drop them into the cooker only in the last few minutes so they dont turn to mush.

3. Taste and tweak at the end. After you shred the chicken, sample the broth and add tiny amounts of soy or fish sauce for umami, a squeeze of lime or a splash more rice vinegar for brightness, or a pinch of sugar or honey to balance salt. Add acid and salt slowly cause you cant take it back.

4. Leftovers and reheating tips. Store noodles separate from the soup, the broth actually gets better next day. When reheating add a little water or stock so it doesnt taste concentrated, and if theres fat on top chill it briefly so you can spoon it off for a cleaner broth.
