Introduction
This healthy Instant Pot Thai noodles recipe is my take on a Thai restaurant favorite of pad thai. Rice wine vinegar, brown sugar, and chili garlic sauce gives the Thai peanut sauce its delicious tangy, sweet, spicy flavor.
When I prepare this recipe on the stovetop, I make it with rice noodles or chow mein noodles. However, pressure cooking those kinds of noodles in the Instant Pot would turn them to a gelatinous mush, so I substitute spaghetti.
The spaghetti holds up to pressure cooking with the peanut sauce and still has a chewy consistency. I love to serve these noodles as a main dish but I also like to serve them as an accompaniment to my Instant Pot Thai Grilled Chicken (Gai Yang) or other grilled dishes. In that case, I omit the chicken and just use veggies.
Of course you could make this recipe on the stovetop, but I love the convenience of cooking the noodles and sauce together. Less mess, and there’s no need to watch over it. Just add the ingredients and walk away!

Tips and Substitutions
Lime juice
The Thai peanut sauce has a bold tangy flavor that my family loves. If you’re not a big fan of tangy flavors, I would suggest that you add half the quantity of lime juice before cooking and add more at the end, to taste.
Make it vegetarian
To make this dish vegetarian, you can omit the chicken and add some extra veggies. Substitute fish sauce with soy sauce. No other changes are needed to the recipe.
Fish Sauce
I really like the quality of Red Boat fish sauce which you can find at Asian grocery stores or on amazon. But it is more expensive than other fish sauce brands. Tiparos is another brand of fish sauce I’ve used – it’s more affordably priced.
There’s no substitute for fish sauce. It adds that depth of flavor, the umami, to dishes. I’ve had vegetarian readers recommend the Fysh brand of sauce. But I haven’t tried it. You may need to add a little extra.
Soy sauce is also a substitute for fish sauce, but there is a flavor difference.
Spaghetti
The spaghetti I use for this recipe is Barilla Spaghetti No. 5 which is a medium thickness. Its stove top cook time is 9 minutes. If the cook time listed on your package is different, you may need to change the pressure cook time.
Spaghetti tends to clump together when cooked in the Instant Pot. You can reduce the clumping drastically by spreading out and layering the dry spaghetti in a criss-cross pattern. If there are still clumps when pressure cooking is completed, stir the spaghetti and separate the clumps using a fork.
Liquid
You may find that there’s extra liquid when you open the Instant Pot. Just allow the Instant Pot Thai Peanut noodles to rest for a few minutes and they should thicken up nicely.
Chili Garlic Sauce
I like to use the Huy Fong brand of chili garlic sauce. It has a tangy, garlicky flavor that I love. You could substitute sriracha sauce or sambal oelek, but they don’t have the same garlic flavor so you may need to add some garlic.
Toppings
I add chopped peanuts, green onions, and bean sprouts as a garnish for these Thai peanut noodles.

Pro Tip
For some foods such as noodles, I find it helpful to release the steam in small bursts: less than 1-second intervals. Once the steam coming out is less forceful, I release the remaining pressure in a steady stream. Read more about the different pressure release methods.
Add vegetables
- Stir the Instant Pot Thai peanut noodles and if there are any strands of spaghetti stuck together, use a fork to separate the strands.
- Add back the reserved sauteed vegetables, cilantro and green onion stalks.
- Stir to combine.
- If you find the noodles to be too liquidy, allow them to rest for 3 to 5 minutes, and they will absorb the extra liquid.

Great recipe! The sauce was so well balanced and delicious. I used a pound of chicken instead of 1/2 pound. It did not seem like too much, and I think you need this much chicken for a family of four. Next time I will increase the veggies too. I love these recipes where you cook the pasta and everything in the same pot.

Thank you, Mary, for sharing your modifications. I’m thrilled that you like the recipe.
Linda
Can I put the sauce on top of the noodles to be sure I won’t get the burn notice?
Paint the Kitchen Red
Linda, I would be more concerned about the noodles giving you a burn error rather than the sauce. So I would recommend that the noodles go on top. Good luck!
Kat
Just having this for lunch and it has great flavor. However, I found it to be heavy on the spaghetti noodles. I followed the recipe exactly but it didn’t look like your photos. Mostly sauce and noodles…and the sauce was a little pasty…maybe it was the type of peanut butter I used. Next time I’d use half the pasta and at least double the veggies, maybe adding some green beans, and maybe a little more chicken.
Paint the Kitchen Red
Kat, thanks for you comment. You can definitely make those changes to suit your tastes. Adding more veggies shouldn’t change anything else in the recipe.
Lynne
I love this recipe! It is absolutely one of my favorite instant pot recipes. I use oyster sauce instead of fish sauce. Still a lot of flavor. There are never any leftovers when I make this!
