Homemade Thai Pasta Salad

I’ll be honest—I used to think pasta salad had to be Italian-style with mayo and olives. That’s just what I grew up eating at every potluck and backyard barbecue. Then one summer, I tossed leftover pasta with some peanut sauce I had in the fridge, and it totally changed my view.

This Thai pasta salad takes that same idea and runs with it. Instead of creamy mayo, you get a sweet and tangy dressing made with soy sauce, honey, and sesame oil. The peanuts add crunch, the ginger gives it a little kick, and the whole thing comes together in about 20 minutes. It’s perfect for when you want something different from the usual pasta salad routine.

What Kind of Pasta Should I Use?

Bowtie pasta (also called farfalle) is perfect for this Thai-inspired salad because its shape holds onto the sesame-soy dressing really well. That said, you can absolutely swap it out for other short pasta shapes like rotini, penne, or fusilli if that’s what you have in your pantry. The key is to cook your pasta just until al dente – you want it to have a little bite to it since it’ll continue to soften slightly as it sits in the dressing. If you’re making this ahead of time, consider slightly undercooking the pasta by about a minute, as it will absorb some of the sauce while it chills in the fridge.

Options for Substitutions

This pasta salad is pretty forgiving when it comes to swaps – here are some options that work well:

• Bowtie pasta: Any short pasta shape works great here. Try rotini, penne, or fusilli – they all hold onto the dressing nicely. Cook according to package directions and you’re good to go.
• Sesame oil: Sesame oil gives this salad its signature flavor, so I’d recommend keeping it if possible. In a pinch, you can use all vegetable oil, but add a teaspoon of tahini to get some of that nutty taste back.
• Honey: Maple syrup or agave nectar work as direct swaps for the honey. You might want to start with slightly less and taste as you go since sweetness levels can vary.
• Soy sauce: Tamari is a great substitute if you need gluten-free, or use coconut aminos for a soy-free option. Both will give you that salty, savory flavor.
• Honey roasted peanuts: Regular roasted peanuts work fine – you can even use cashews or almonds instead. Just chop them roughly so they mix in better.
• Cilantro: If you’re one of those people who thinks cilantro tastes like soap, swap it for fresh basil or mint. Both pair nicely with the Asian flavors in this salad.

Watch Out for These Mistakes While Cooking

The biggest mistake people make with pasta salad is not rinsing the cooked pasta with cold water after draining, which stops the cooking process and prevents the noodles from turning mushy and sticking together in clumps.

Another common error is adding the peanuts and cilantro too early – if you toss them in before chilling, the peanuts will get soggy and the cilantro will wilt and turn brown, so always wait until right before serving to add these fresh ingredients.

When heating the oil mixture, keep the heat on medium-low and watch it carefully since sesame oil can burn quickly and turn bitter, ruining the entire dressing.

Finally, make sure to toss the pasta with the warm dressing while the pasta is still slightly warm, as this helps the flavors soak in better than if you wait until everything is completely cold.

What to Serve With Thai Pasta Salad?

This pasta salad is pretty filling on its own, but I love serving it alongside grilled chicken, shrimp, or even some crispy tofu if you want to add more protein to the meal. It’s also great as a side dish at summer cookouts with burgers or grilled salmon, since the sweet and savory flavors go well with just about anything off the grill. If you’re looking for something lighter to round out the plate, some fresh cucumber slices or edamame make for a nice, refreshing addition. You could also serve it with spring rolls or pot stickers for a fun Asian-inspired spread that everyone will enjoy.

Storage Instructions

Store: This pasta salad actually gets better after sitting in the fridge for a few hours because the flavors have time to soak in. Keep it in an airtight container in the refrigerator for up to 4 days. You might need to give it a good stir before serving since the dressing can settle at the bottom.

Make Ahead: Thai pasta salad is perfect for making ahead! I like to prep it the night before a potluck or picnic. Just wait to add the peanuts and fresh cilantro until right before serving so they stay crunchy and fresh. The pasta will absorb some of the dressing as it sits, so you can drizzle a little extra sesame oil or soy sauce if needed.

Serve: This salad is meant to be served cold or at room temperature, so there’s no need to reheat. Just pull it out of the fridge about 15 minutes before serving if you want to take the chill off. Give it a quick toss and add a sprinkle of extra peanuts or green onions for a fresh look.

Ingredients

For the pasta:

• 12 oz bowtie pasta

For the dressing:

• 2 tbsp vegetable oil
• 1/2 cup toasted sesame oil
• 2 tsp red pepper flakes
• 1/4 cup honey
• 1/4 cup soy sauce
• 1/4 tsp salt
• 2 tbsp rice vinegar
• 1 tbsp freshly grated ginger

For the garnish:

• 1/2 cup fresh cilantro, chopped
• 2/3 cup honey roasted peanuts, roughly chopped
• 1/2 cup green onions, sliced

Step 1: Build the Thai-Inspired Dressing Base

• 2 tbsp vegetable oil
• 1/2 cup toasted sesame oil
• 2 tsp red pepper flakes
• 1/4 cup honey
• 1/4 cup soy sauce
• 1/4 tsp salt

Heat the vegetable oil and sesame oil together in a small saucepan over medium heat.

Once shimmering, add the red pepper flakes and let them bloom for 1-2 minutes—this releases their full spicy flavor into the oil.

Remove from heat and stir in the honey, soy sauce, and salt until well combined.

The residual heat will help meld these flavors together.

Set the dressing aside to cool slightly while you prepare the pasta.

Step 2: Cook and Cool the Pasta

• 12 oz bowtie pasta
• dressing mixture from Step 1

Bring a large pot of salted water to a boil and cook the bowtie pasta until just al dente, about 10-12 minutes—don’t overcook, as the pasta will continue to absorb the dressing and soften as it chills.

Drain the pasta thoroughly in a colander and transfer it to a large bowl.

Pour the warm dressing from Step 1 over the hot pasta and toss well to coat every piece; the warm pasta will absorb the flavors beautifully.

I like to let it cool to room temperature before chilling so the flavors have time to develop without the heat breaking down the delicate cilantro that goes in later.

Step 3: Chill and Develop Flavor

Cover the pasta mixture and refrigerate for at least 4 hours, or ideally overnight.

This resting time allows the pasta to fully absorb the dressing and develop deep, complex flavors.

The cold temperature also helps meld the sesame oil, soy sauce, and honey into a cohesive taste.

Step 4: Finish with Fresh Elements and Aromatics

• 2 tbsp rice vinegar
• 1 tbsp freshly grated ginger
• 1/2 cup fresh cilantro, chopped
• 2/3 cup honey roasted peanuts, roughly chopped
• 1/2 cup green onions, sliced
• chilled pasta from Step 3

About 30 minutes before serving, remove the pasta salad from the refrigerator.

Add the rice vinegar and freshly grated ginger, stirring gently to distribute them throughout.

Just before serving, fold in the fresh cilantro, honey roasted peanuts, and green onions—I add these last to keep the cilantro bright and the peanuts crispy rather than soft and soggy.

Taste and adjust seasoning if needed, then serve chilled.
