Key Ingredients

• Noodles: High-fiber, high-protein spaghetti adds extra fiber and protein, but use any pasta you like.
• PB2: Powdered peanut butter (PB2 or PBfit) provides peanut flavor with fewer calories than traditional peanut butter.
• Almond Milk: Unsweetened almond milk thins the sauce to a creamy, pourable texture.
• Rice Vinegar: Adds a bright, tangy balance to the sauce.
• Soy Sauce: Low-sodium soy sauce brings savory, umami depth.
• Sambal Oelek: Gives the sauce its spicy kick.
• Honey: A touch of sweetness to balance acidity and heat.
• Sesame Oil: Provides a subtle, nutty richness.
• Garlic & Ginger: Fresh garlic and ginger add depth and a zesty lift.

See the recipe card below for full measurements.

Substitutions & Variations

• Less spicy: Start with 1 tablespoon sambal oelek and add more to taste. If you lack chili crunch oil, increase sambal slightly.
• Sambal substitutions: Use sriracha or chili oil — start with 1 tablespoon and adjust.
• More heat: Add crushed red pepper flakes.
• Honey swap: Use maple syrup, sugar-free honey, or another sweetener of choice.
• Milk options: Oat, cashew, soy, or regular milk can replace almond milk.
• Vegan: Swap honey for maple syrup and use plant-based milk and vegan chili oil.
• Gluten-free: Use gluten-free noodles and tamari instead of soy sauce.
• Add protein: Stir in 1 cup cooked shredded chicken (rotisserie works well) for a heartier meal.
• Veg add-ins: Shredded cabbage, carrots, or diced cucumber add crunch and freshness.

How To Make Healthy Spicy Peanut Noodles with PB2

1. Cook the pasta according to package directions until al dente. Drain and set aside.

2. Whisk rice vinegar, sambal oelek, soy sauce, honey, sesame oil, minced garlic, grated ginger, and optional chili crunch oil in a medium bowl until combined.

3. Stir in the powdered peanut butter and almond milk until the sauce is smooth and creamy. Add more milk to thin or more PB2 to thicken as needed.

4. Toss the drained noodles with the sauce in the saucepan using tongs until evenly coated. Warm gently over low heat if desired.

5. Serve in bowls topped with sliced green onions and chopped peanuts. Enjoy warm.

Expert Tips

• Fresh ginger: Grate what you need and freeze the rest, or use frozen ginger cubes for convenience.
• Mix the sauce: Combine the liquid ingredients first, then add PB2 and milk to prevent clumps and achieve a smoother sauce.
• Adjust consistency: Add more almond milk to thin, or a little extra PB2 to thicken the sauce.
• Coat thoroughly: Use tongs to toss the noodles so every strand is evenly coated.
• Don’t overcook: Cook pasta al dente so it holds up when tossed with the sauce.
• Reheating: When reheating leftovers, add a splash of milk and stir to restore creaminess.

Serving Suggestions

Finish with sliced green onions and chopped peanuts for freshness and crunch. These noodles are great on their own or paired with a light side like an Asian cucumber salad. They also go well with roasted vegetables or a simple protein like grilled chicken or tofu.

Storage Instructions

Store leftovers in an airtight container in the refrigerator for 1–2 days. The sauce will thicken in the fridge; when reheating, add a splash of almond milk and stir until the sauce returns to a creamy consistency.
