Spicy Peanut Butter Noodles Recipe

I can’t get enough of these spicy Thai peanut noodles because they’re saucy, satisfying, vegan, and just as good straight from the fridge. This is the meal prep recipe that makes lunch feel exciting all week.

I’m obsessed with these spicy peanut butter noodles because they hit every craving I have at once: creamy, spicy, tangy, salty, and a little sweet without feeling heavy. The sauce clings to rice noodles in that glossy, messy, can’t-stop-twirling way, and the Sriracha brings just enough heat to keep me going back for another bite.

And another. I love them cold straight from the fridge, but I’ll happily eat them hot when I want something fast that still tastes bold.

Meal prep that I actually look forward to. No sad desk lunch energy, just saucy vegan noodles with serious attitude.

Ingredients

• Rice noodles or spaghetti make it slurpy, cozy, and weeknight-friendly.

  Basically, don’t skip them.

• Cilantro is optional, but Plus, it makes the bowl taste fresher.

Ingredient Quantities

• 8 ounces rice noodles or spaghetti
• 1 cup creamy peanut butter (natural or unsweetened)
• 3 tablespoons soy sauce or tamari
• 2 tablespoons maple syrup or brown sugar
• 2 tablespoons rice vinegar
• 1 tablespoon fresh lime juice
• 1 tablespoon sesame oil
• 1 to 2 tablespoons Sriracha or chili garlic sauce, to taste
• 1 tablespoon grated fresh ginger
• 2 garlic cloves, minced
• 1/3 to 1/2 cup coconut milk or warm water to thin the sauce
• 1 cup shredded carrots
• 1 cup thinly sliced cucumber or bell pepper
• 3 scallions, thinly sliced
• 1/4 to 1/2 cup chopped roasted peanuts
• 2 tablespoons toasted sesame seeds

How to Make this

1. Cook 8 ounces rice noodles or spaghetti according to package instructions until just tender, drain and rinse under cold water if serving cold, or reserve a little cooking water if serving hot.

2. In a bowl whisk together 1 cup creamy peanut butter, 3 tablespoons soy sauce or tamari, 2 tablespoons maple syrup or brown sugar, 2 tablespoons rice vinegar, 1 tablespoon fresh lime juice, 1 tablespoon sesame oil, 1 to 2 tablespoons Sriracha or chili garlic sauce, 1 tablespoon grated fresh ginger, and 2 minced garlic cloves.

3. Thin the peanut sauce with 1/3 to 1/2 cup coconut milk or warm water until smooth and pourable; season with salt and freshly ground black pepper to taste.

4. If keeping noodles hot, toss the drained hot noodles with a few tablespoons of the sauce to coat and help the sauce absorb; add reserved cooking water as needed to loosen.

5. Add 1 cup shredded carrots, 1 cup thinly sliced cucumber or bell pepper, and 3 thinly sliced scallions to the noodles and toss with remaining sauce until everything is evenly coated.

6. Stir in 1/4 cup chopped fresh cilantro if using and adjust heat with more Sriracha or more lime juice for brightness.

7. Transfer to a serving bowl or divide into meal prep containers; for cold salads chill at least 30 minutes to let flavors meld.

8. Sprinkle 1/4 to 1/2 cup chopped roasted peanuts and 2 tablespoons toasted sesame seeds over the top before serving.

9. Taste and adjust salt, pepper, sweetness, acidity, or spice as desired, then serve hot or cold.

Pro Tips

1. Warm the peanut sauce slightly before tossing with hot noodles so it loosens easily and clings to every strand; if it gets too thick, add hot pasta water a tablespoon at a time to reach the perfect silkiness.
2. For contrast, keep one crunchy element separate until serving, like extra chopped peanuts or thin cucumber ribbons, so textures stay bright instead of turning soggy.
3. Taste and tweak like a pro: add more lime for brightness, a pinch of sugar or maple for balance, or a splash of soy for saltiness. Make small adjustments, tasting after each change.
4. If you plan ahead, store noodles and sauce separately for up to 3 days, then combine just before serving. The flavors will meld better if the mixed salad rests for at least 30 minutes, but leftovers also reheat nicely if you prefer it warm.
