This vibrant Spicy Thai Pasta Salad combines tender pasta with a bold, chili-infused oil that creates an irresistible blend of sweet, spicy, and savory flavors. Perfect for potlucks, meal prep, or a refreshing dinner, this pasta salad has become a staple in my home that always disappears in record time. I've learned from experience to always make a double or triple batch because everyone comes back for seconds and thirds!
The first time I brought this to a neighborhood potluck, it was the first dish completely emptied, and three different people asked for the recipe before the evening was over! There's something about the combination of the infused oil, pasta, and fresh garnishes that makes this utterly addictive.
Ingredients
- 1 pound bowtie pasta: The shape holds the flavorful sauce perfectly in all its nooks and crannies. Other small shapes like penne or rotini work well too.
- ¼ cup vegetable oil: Creates the base for our infused oil. Use a neutral oil with a high smoke point.
- 2 tablespoons sesame oil: Adds that distinctive nutty flavor that's essential to Asian-inspired dishes.
- 1-2 teaspoons crushed red pepper flakes: The star ingredient that brings the heat! Adjust to your spice preference.
- ¼ cup honey: Balances the spice with perfect sweetness. Use high-quality honey for best results.
- ¼ cup soy sauce: Provides that umami-rich saltiness. Low-sodium works well if you're watching salt intake.
- ½ teaspoon salt: Enhances all the flavors and balances the sweetness.
- ½ cup fresh cilantro, chopped: Adds bright, fresh flavor that cuts through the richness of the oil.
- ½ cup roasted peanuts, chopped: Provides wonderful crunchy texture contrast. Optional if there are allergies.
- ½ cup green onions, sliced: Gives a mild onion flavor and beautiful color to the finished dish.
- Optional: 2 cups shredded rotisserie chicken: Makes this a heartier main dish with added protein.

Step-by-Step Instructions
- Step 1:
- Cook the pasta - Bring a large pot of salted water to a boil. Add the bowtie pasta and cook according to package directions until al dente, usually 8-10 minutes. Be careful not to overcook as the pasta will continue to absorb the dressing. Drain thoroughly in a colander, shaking to remove excess water.
- Step 2:
- Prepare for infusion - Transfer the drained pasta to a large mixing bowl. Meanwhile, in a small saucepan, combine the vegetable oil and sesame oil over medium heat. Allow the oils to warm up gently - you want them hot but not smoking.
- Step 3:
- Create the infused oil - Add the crushed red pepper flakes to the warm oils. As they hit the oil, they'll begin to sizzle slightly. Stir continuously for 2 minutes to infuse the oils with the spicy flavor. This process releases the capsaicin (the compound that makes peppers hot) into the oil, creating a beautifully spiced base.
- Step 4:
- Complete the dressing - Add the honey, soy sauce, and salt to the infused oil. Stir well to combine all ingredients and turn off the heat. The honey will melt into the warm oil, creating a sweet-spicy emulsion.
- Step 5:
- Combine with pasta - While the dressing is still warm, pour it over the cooked pasta in the large bowl. Using tongs or two large spoons, toss thoroughly until every piece of pasta is evenly coated with the infused oil mixture. The warm pasta will absorb some of the flavors immediately.
- Step 6:
- Allow flavors to develop - Cover the bowl tightly with plastic wrap and refrigerate for at least 4 hours, but preferably overnight. This resting time is crucial as it allows the pasta to fully absorb the flavors of the infused oil. The spice level will also mellow slightly and integrate better with the other flavors.
- Step 7:
- Add fresh elements - Just before serving, add the chopped cilantro, peanuts, and sliced green onions to the pasta. If you're including chicken, add it now as well. Toss everything together until well combined.
- Step 8:
- Serve and enjoy - Transfer to a serving bowl or individual plates. This salad is delicious cold or at room temperature and makes a beautiful presentation with the vibrant colors of the garnishes.
The Magic of Infused Oil
The heart of this recipe is the chili-infused oil that gives the pasta its distinctive flavor. When red pepper flakes are heated in oil, they release their capsaicin and flavor compounds, creating an infusion that's more complex and evenly distributed than simply adding the flakes directly to the dish. The warmth of the oil also helps bloom the sesame oil's nutty aroma, making the entire dressing more fragrant and flavorful.
Make It Your Own
This versatile recipe can be adapted in many ways:
- For a vegetarian protein boost, add edamame or cubed tofu
- Mix in julienned carrots, thinly sliced bell peppers, or sugar snap peas for added crunch and nutrition
- Substitute part of the honey with peanut butter for a more satay-like flavor
- Add a squeeze of lime juice just before serving for brightness
The Importance of Patience
While it might be tempting to dive right in after mixing the pasta with the dressing, the magic of this dish truly happens during the rest period. As the pasta sits in the refrigerator, it absorbs the flavors of the infused oil, mellowing the initial sharpness of the red pepper and allowing the sweet and savory elements to harmonize. The texture also improves as the pasta becomes fully infused.
I learned the importance of thoroughly draining the pasta the hard way - excess water dilutes the dressing and can make the salad soggy. Now I drain the pasta in a colander and give it a few good shakes before transferring it to the mixing bowl. This simple step ensures that the infused oil coats the pasta perfectly.

After making this countless times, I've discovered that adding a tablespoon of toasted sesame seeds along with the peanuts creates an even more complex flavor profile. It's a small addition that makes a noticeable difference in the final dish.
This Spicy Thai Pasta Salad has become one of my signature dishes for gatherings, and I'm frequently asked to bring it to potlucks and family events. The combination of spicy, sweet, and savory elements with the fresh crunch of the garnishes creates a pasta salad that's anything but ordinary. Whether you serve it as a side or bulked up as a main dish, it's guaranteed to become a requested favorite!
