Thai Basil Pesto Ingredients
For the Pesto
• Thai Basil – This herb gives the pesto its distinctive flavor; you can substitute it with sweet basil if needed but use extra for a stronger taste.
• Jalapeno (or other hot chili) – Adds a spicy kick; remove seeds for a milder sauce or swap with cayenne pepper for a different heat.
• Garlic – Use fresh garlic for the best aroma and flavor; avoid powdered varieties to keep the taste vibrant.
• Green Onions – These provide mild onion notes; chop finely for even distribution in the pesto.
• Dry Roasted Peanuts – They contribute a crunchy texture and rich flavor; cashews or walnuts can be used instead if desired.
• Oyster Sauce (or Gluten-Free Oyster Sauce) – This adds a savory umami taste; make sure to choose gluten-free if needed.
• Soy Sauce (or Gluten-Free Soy Sauce) – Enhances the sauce’s umami; tamari is a great gluten-free substitute.
• Fish Sauce – Use sparingly, as it imparts a strong salty flavor that enhances the overall taste.
• Packed Brown Sugar – Balances spiciness and saltiness; it’s optional but recommended for depth of flavor.
• Vegetable Oil – Acts as the base for the pesto; any mild-flavored oil can be swapped if preferred.
• Sesame Oil – Essential for its nutty flavor and aroma, so it’s best not to substitute this ingredient.
For Serving
• Rice Noodles – Serve as a gluten-free alternative to traditional pasta; cook according to package instructions for the best texture.
Step‑by‑Step Instructions for Thai Basil Pesto
Step 1: Chop Peanuts and Garlic
Begin by placing the dry roasted peanuts and fresh garlic cloves into a food processor. Pulse the mixture for about 10-15 seconds until the peanuts are coarsely chopped, and the garlic is finely minced. Ensure to scrape down the sides of the bowl for even blending. This initial step lays the flavorful foundation for your Thai Basil Pesto.
Step 2: Add the Remaining Ingredients
Next, add the Thai basil leaves, jalapeno (seeds removed for milder flavor), green onions, oyster sauce, soy sauce, fish sauce, and packed brown sugar to the food processor.

Step 3: Incorporate Oils for Texture
With the food processor running, slowly stream in the vegetable oil and sesame oil over the top of the mixture. Continue processing for another 20-30 seconds until the pesto becomes a thick, smooth paste. The oils will help emulsify the flavors, resulting in a rich and creamy texture for your Thai Basil Pesto.
Step 4: Adjust Seasoning and Consistency
Taste your pesto and adjust as necessary by adding more salt, fish sauce, or sugar to achieve your desired flavor balance. If the consistency is too thick, you can add a splash more of the vegetable oil to loosen it up. Pulse for an additional 10 seconds to incorporate any adjustments.
Step 5: Combine with Rice Noodles
Once satisfied with your Thai Basil Pesto, prepare the rice noodles according to the package instructions. When they are cooked and warm, transfer them into a large mixing bowl. Spoon the prepared pesto over the noodles, tossing gently to coat them evenly, ensuring every bite is packed with flavor.
