Full Ingredients

Noodles

• 8 oz (225 g) thin wheat noodles (lo mein noodles, ramen noodles without seasoning packets, or spaghetti)
• Water for cooking (enough to cover noodles by 1 inch / 2.5 cm)

Peanut-Sesame Sauce

• 1/3 cup (80 g) creamy peanut butter
• 3 tbsp (45 ml) low-sodium soy sauce
• 1 tbsp (15 ml) toasted sesame oil
• 2 tsp (10 ml) honey
• 1 tbsp (15 ml) rice vinegar
• 2 cloves garlic, finely grated or minced
• 3 tbsp (45 ml) hot water, plus more as needed to loosen
• Optional for heat: 1/4 tsp red pepper flakes

Mix-Ins

• 1 cup (110 g) shredded carrots
• 1 cup (120 g) shredded or julienned cucumber
• Optional: 1 cup (140 g) cooked shredded chicken (rotisserie chicken works well)

Finish & Toppings

• 1/4 cup (35 g) roasted peanuts, crushed
• Optional: 2 scallions, thinly sliced
• Optional: 1 tbsp toasted sesame seeds
• Optional: 1 tbsp chopped cilantro
• Optional: 1 lime, cut into wedges

Step-by-Step Instructions

Step 1: Prep your mix-ins and toppings

Shred the carrots (a box grater works well) and shred or julienne the cucumber into thin strips. Thinly slice the scallions if using. Roughly crush the roasted peanuts (a knife, mortar and pestle, or a zip-top bag with a rolling pin all work).

Having everything ready is helpful because the sauce comes together quickly once the noodles are hot.

Step 2: Microwave the noodles

Place the noodles in a large microwave-safe bowl (at least a 2.5–3 quart bowl so it doesn’t boil over). Add enough water to cover the noodles by 1 inch (2.5 cm).

Microwave on HIGH (100% power) for 9 minutes, stirring at the 4-minute mark to separate strands and prevent sticking. Let stand for 2 minutes to finish softening.

Carefully drain the noodles in a colander. Do not rinse if you want the sauce to cling well; if your noodles seem very starchy or sticky, rinse quickly with warm water and drain thoroughly.

Step 3: Whisk the peanut-sesame sauce until smooth

While the noodles cook (or right after), add the peanut butter, soy sauce, toasted sesame oil, honey, rice vinegar, and garlic to a medium bowl.

Whisk vigorously until the mixture looks thick and mostly smooth. If it’s very stiff, microwave the bowl for 20 seconds on HIGH to soften the peanut butter, then whisk again.

Step 4: Thin the sauce to a glossy, pourable consistency

Whisk in 3 tbsp (45 ml) hot water until the sauce turns glossy and pourable (like a thick salad dressing). Add the red pepper flakes here if you want a gentle kick.

If needed, add more hot water 1 tbsp at a time until the sauce easily coats the back of a spoon.

Step 5: Toss noodles with sauce

Return the drained noodles to the large bowl (or use the bowl you cooked them in, wiped dry if needed). Pour the sauce over the warm noodles.

Toss thoroughly with tongs or two forks for 30–45 seconds, until every strand is coated and the noodles look evenly glossy.

Step 6: Add vegetables (and optional chicken)

Add the shredded carrots and cucumber, plus the cooked shredded chicken if using. Toss again until everything is evenly distributed.

If the noodles tighten up as they sit, loosen with 1–2 tbsp hot water and toss once more.

Step 7: Finish, taste, and serve

Taste and adjust: for more saltiness add 1 tsp soy sauce; for more sweetness add 1/2 tsp honey; for more tang add 1 tsp rice vinegar; to thin add 1 tsp hot water.

Serve warm or at room temperature. Top each bowl with crushed peanuts and optional scallions, sesame seeds, and cilantro. If you like, squeeze lime over the top right before eating.

Pro Tips

• Use hot water to emulsify: Adding hot water gradually helps the peanut butter turn silky instead of clumpy.
• Warm noodles coat best: Toss the sauce with noodles while they’re still warm so the sauce spreads evenly.
• Prevent microwave boil-over: Use a very large bowl and stir halfway through; if your microwave runs hot, reduce cook time to 8 minutes and let stand 3 minutes.
• Balance matters: Peanut sauces shine when sweet, salty, and tangy are all present. Make small adjustments at the end.
• For extra crunch: Add an additional 1/2 cup thinly sliced cabbage or bell pepper.

Variations

• Spicy Peanut Noodles: Add 1–2 tsp chili garlic sauce or sriracha to the sauce, plus an extra 1 tbsp hot water to keep it pourable.
• Sesame-Ginger Twist: Add 1 tsp freshly grated ginger and swap honey for 2 tsp brown sugar.
• Vegetarian Protein: Replace chicken with 8 oz (225 g) cubed baked tofu or 1 cup shelled edamame (thawed).

Storage & Make-Ahead

Store leftovers in an airtight container in the refrigerator for up to 3 days. Peanut sauce thickens as it chills, so when reheating, add 1–2 tbsp water and microwave on HIGH in 30-second bursts, tossing between bursts, until warmed through (usually 60–90 seconds). You can also enjoy it cold like a noodle salad.

Make-ahead tip: whisk the sauce up to 3 days ahead and refrigerate. Before using, let it sit at room temperature for 10 minutes and whisk in 1–3 tbsp hot water to loosen.
