Leftovers are one of my favorite things in this world! There isn't much that beats cooking once and eating twice, right? This healthy leftover noodle recipe for Peanut Pasta Salad uses leftover spaghetti noodles and lots of fresh vegetables for a quick and healthy meal. I like to make this Vegan Pasta Salad the day after I make spaghetti because I inevitably end up with too many noodles.
A little spicy, and full of crunchy vegetables, this Peanut Pasta Salad with spicy peanut sauce is a delicious way to use up leftover spaghetti noodles and turn them into something new. It's fast and easy to make and perfect for dinner, lunch boxes, as a side dish, and potlucks!

This pasta salad is definitely a fan favorite! When my nephew was coming to visit, I asked him what he wanted me to make (to pick anything I've posted on Instagram) and he chose this!

🥘Ingredient Notes
- Chunky peanut butter. This gives the dressing a yummy peanut flavor with some texture.
- Soy Sauce. Adds a unami flavor.
- Rice Vinegar. Adds a mild tanginess to the dressing!
- Olive oil. Helps to balance the acidity from the rice vinegar.
- Fresh ginger and garlic (minced). Add a fresh and fragrant zest to this salad!
- Brown sugar. Brown sugar balances the soy sauce and tang from the rice vinegar.
- Sesame Seeds. Add a delicious sesame taste and a nice texture.
- Sriracha sauce. Sriracha sauce gives it the spiciness. Add more for more spicy and less for less spicy!
- Cooked spaghetti noodles (cold noodles). Leftover spaghetti is the star of the show and serves as the starch in this salad.
- Fresh grated carrots, chopped cucumber, green onion, and red pepper. These fresh vegetables give the salad a great crunchy texture!
- Fresh Cilantro (chopped). Cilantro adds a welcome burst of freshness, lemon-peppery taste and helps to balance the spice.
- Roasted Unsalted Peanuts. Peanuts serve as the protein in this salad and add to the texture!

📖 Variations & Substitutions
- Peanut Butter. You can use smooth peanut butter or use light peanut butter to reduce the fat content.
- Spaghetti Noodles. You can substitute a different type of noodle, such as leftover fettuccine noodles or rice noodles.
- Garlic. You can use store-bought minced garlic in a jar.
- Olive oil. You can use canola, vegetable, or sesame oil (I wouldn't recommend using straight sesame oil, as it's very strong - just use a little mixed with another oil).
- Rice Vinegar. You can use plain or seasoned rice vinegar.
- Unsalted Peanuts. You can use raw, blanched, or boiled peanuts. But if you're using raw, it's recommended that you cook them first. I like to use roasted peanuts. Make sure there is no salt on them or it will be way too salty and ruin the salad.
Top Tip
Keep your ginger and peanuts in the freezer - they will last much longer! You can take your ginger out and grate it (while still frozen) into food. This is so much easier!
🔪How to Make Peanut Pasta Salad
- Step 1: In a medium bowl, whisk together peanut butter, soy sauce, rice vinegar, sesame seeds, olive oil, sriracha sauce, water, minced ginger, minced garlic, and brown sugar.
- Step 2: Combine cold cooked noodles with sliced vegetables, cilantro, and peanuts.
- Step 3: Pour the dressing over the pasta and vegetables and mix well. Garnish with additional chopped cilantro, peanuts, and additional sesame seeds, if desired. Enjoy!
🍝Which type of Spaghetti to use
Then there's the question of which spaghetti noodles to use. Whole wheat spaghetti takes a long time to cook and personally, I find it a bit too dense. I prefer to use "smart pasta" because it cooks faster than whole wheat but you still get 4X as much fibre than if you ate white pasta.
Although it's not quite as healthy as whole wheat, you are still getting that fibre. And if you're not a fan of whole wheat, it's a good alternative. You can read more about smart pasta vs. whole wheat pasta here.
👪 Serving size
This recipe serves 8. However, you can easily adjust the recipe to serve as many as you need. Simply click on the serving size, choose the number of servings you'd like, and the amounts will adjust accordingly.
🔢WW POINTS
This recipe is 9 ww points using regular pasta and regular peanut butter Use light peanut butter to reduce the fat content and bring down the Weight Watcher points. You can also use a ww friendly pasta to further reduce the points.
🌡️Storing
You can store this in the fridge for up to 2 days after you make it OR make it 2 days in advance. I would not recommend storing it longer because the veggies will get soggy.
These ingredients don't stand up to freezing.
So if you have leftover spaghetti noodles to use up, you'll LOVE this Peanut Noodle Salad with creamy peanut sauce!

Super fast. Super yum. A really fresh, tasty dish for summer. Packed with flavour.

I'm so glad you enjoyed it, Char!

This salad is DIVINE! The ginger and cilantro just sing! It's also flexible and/or forgiving. I have mirin I rarely use, so I subbed some for the b. sugar. (I still had to add about 1 tsp of b. sugar to get my desired sweetness.) Didn't have enough RV, so made up the difference with WWV and lime juice. Added some cooked shrimp, a few chickpeas and avocado to the finished product. Wow! I'm keeping the dressing, pasta, and veggie mix all separate since I'm cooking for only 2 people, and this recipe made a lot of dressing. It was all so delicious. I can't say enough good things about it!
Terri Gilson
I'm so glad you loved it, Monique!

AWESOME.
Used leftover small bowtie noodles & finely grated the carrot, no cilantro & agave nectar instead of brown sugar - we paired it with sesame teriyaki soaked grilled salmon.
I cut up the second half of my salmon portion & mixed it in with my serving of leftover spicy peanut pasta.
YUM.
This was right up my 15 year old's alley to.
Win..win..lol
Terri Gilson
I'm so glad you liked it! Salmon sounds like a great pairing!

I have a bunch of leftover pasta that I’m trying to figure out what to do with for dinner tomorrow and can’t wait to try this recipe. Would you have any suggestions for what to eat along with it as a side?
Terri Gilson
Honestly, we eat this as a meal! But if you leave out the peanuts, it’s a great side salad with bbq pork or chicken ?
Tiia
Great flavor. I added cherry tomatoes to the salad and a bit of sesame oil to the dressing. Will definitely be making this again.
Terri Gilson
Hi Tiia- glad you enjoyed it! And thanks for stopping by to comment- I love getting feedback ?Terri

Mindy
Looks delicious! Do you think I could substitute soba noodles for the spaghetti?
Terri Gilson
Hi Mindy- I don’t see why you couldn’t! Really, any noodles would work-enjoy!

This is a great way to use leftover noodles, which usually get thrown away at my house. I always seem to cook just the right amount of sauce but way too many noodles. Thanks for sharing!
