How to Make Cold Peanut Noodle Salad

Step 1: Make the dressing

In a small bowl, add rice vinegar, vegetable oil, peanut butter, minced garlic, cayenne pepper, and salt.

Use an immersion blender to blend until smooth and emulsified.

If the dressing is too thick, thin it out with a little more oil or vinegar to your preference.

Step 2: Prep the salad ingredients

Cook the spaghetti in salted water until al dente.

Drain and rinse well under cold water until fully cooled.

Transfer to a large bowl.

Step 3: Assemble the salad
Add shredded red cabbage, shredded carrots, sliced green onions, roasted peanuts, sesame seeds, chopped cilantro, and basil to the bowl with the noodles.

Step 4: Toss and chill
Pour the peanut dressing over the noodle mixture and toss thoroughly to coat everything.

Cover and refrigerate until ready to serve—ideally for 30 minutes or more to let the flavors meld.

Step 5: Serve and enjoy!
Serve cold, topped with extra peanuts, sesame seeds, or fresh herbs if you like!
