Ingredients You’ll Need
Creating these noodles is a breeze thanks to a handful of simple yet essential ingredients that each play their own unique role—from buttery smooth peanut flavor and spicy kick to the fresh crunch and aromatic notes. Here’s what you’ll want to gather before you start:
- 8 oz noodles: Choose spaghetti, rice noodles, or soba to suit your preference—each brings a slightly different texture but all work beautifully.
- 1/3 cup creamy peanut butter: The heart of the sauce, providing rich, nutty creaminess that envelops every strand of noodle.
- 2 tablespoons soy sauce: Adds a salty umami depth that balances the sweetness and spice.
- 1 tablespoon rice vinegar: Delivers brightness and a subtle tang to lighten the richness.
- 1 tablespoon sesame oil: Infuses a toasty, fragrant layer of flavor that makes the dish feel authentically Asian.
- 1 tablespoon chili garlic sauce: This brings the perfect spicy punch—adjust to your liking for milder or bolder heat.
- 1 teaspoon honey or maple syrup: Just a touch of sweetness to play against the spicy and salty notes.
- 1 clove garlic, minced: Garlic adds a sharp, aromatic underpinning that wakes up the whole sauce.
- 1/2 teaspoon grated fresh ginger: Brings fresh zing and a subtle warmth to the mix.
- 1/4 cup warm water: Used to thin the sauce to a perfect creamy consistency for tossing.
- 1 cup cucumber, julienned or thinly sliced: Offers cooling crunch and freshness, balancing the spicy sauce beautifully.
- 2 green onions, sliced: Adds a mild oniony snap and vibrant green color.
- 1 tablespoon toasted sesame seeds: For nutty crunch and a pretty finish.
- Chopped peanuts and fresh cilantro (optional): Extra garnishes that elevate texture and brighten flavors just before serving.
How to Make Spicy Peanut Noodles with Cucumber Recipe
Step 1: Cook and Prepare the Noodles
Start by cooking your choice of noodles—whether it’s spaghetti, rice noodles, or soba—following the package instructions carefully. Once cooked, drain the noodles and rinse them under cold water. This stops the cooking process and prevents the noodles from sticking together, ensuring a perfect texture when mixed with the sauce later.
Step 2: Whisk Together the Spicy Peanut Sauce
In a medium bowl, combine the creamy peanut butter with soy sauce, rice vinegar, sesame oil, chili garlic sauce, honey, minced garlic, and fresh ginger. Add warm water little by little while whisking vigorously until the sauce is luxuriously smooth and creamy, with just the right consistency to coat every noodle.
Step 3: Toss Noodles with Sauce and Fresh Veggies
Transfer the cooled noodles into a large bowl and pour over the spicy peanut sauce. Toss gently but thoroughly so every noodle is coated in that luscious sauce. Then fold in the crisp, julienned cucumber and sliced green onions, mixing just enough to combine while keeping the cucumber’s refreshing crunch intact.
Step 4: Plate and Garnish
Divide the sauced noodles into serving bowls and sprinkle with toasted sesame seeds, chopped peanuts, and fresh cilantro if you want that extra layer of texture and vibrant color. This dish shines when served chilled or at room temperature, making it incredibly versatile for any occasion.
How to Serve Spicy Peanut Noodles with Cucumber Recipe

Garnishes
The toppings really bring this dish alive, enhancing both texture and flavor. I love adding crunchy chopped peanuts for bite, fresh cilantro for herbal brightness, and a sprinkle of toasted sesame seeds for a subtle nuttiness that complements the peanut sauce perfectly.
Side Dishes
This noodle bowl pairs beautifully with light sides like steamed edamame, crispy spring rolls, or a simple Asian slaw. You can also round out the meal with grilled tofu or chicken skewers to add protein and make it more substantial.
Creative Ways to Present
For a stunning presentation at your next dinner party, serve the noodles in individual clear glass bowls to showcase the colorful layers. Alternatively, toss everything in a large wooden bowl for a family-style feel that invites shared enjoyment. Adding thinly sliced bell peppers or shredded carrots not only adds crunch but also a pop of color that makes the dish even more inviting.
Make Ahead and Storage
Storing Leftovers
You can store any leftovers in an airtight container in the refrigerator for up to 3 days. Because the noodles are tossed in a rich sauce, they keep their flavor well. Just give the noodles a quick toss before serving again to redistribute the sauce evenly.
Freezing
This dish is best enjoyed fresh or refrigerated rather than frozen, as the cucumbers and noodles may change texture and become soggy once thawed. If you want to prep in advance, consider making the sauce separately and mixing it with freshly cooked noodles and veggies when ready to eat.
Reheating
If you prefer your noodles warm, gently microwave them for short bursts, stirring in between to prevent the peanut sauce from drying out. Avoid overheating to keep the noodles tender and the sauce creamy. Alternatively, you can serve them chilled or at room temperature for a refreshing change.
FAQs
Can I use a different type of nut butter in this Spicy Peanut Noodles with Cucumber Recipe?
Absolutely! While creamy peanut butter gives that classic flavor, you can experiment with almond or cashew butter for a different nutty twist. Just ensure the consistency is smooth for easy mixing with the sauce ingredients.
How spicy is this recipe, and can I adjust the heat level?
The spiciness mainly comes from the chili garlic sauce, which you can easily adjust. For less heat, reduce the amount or substitute with a milder sriracha. For a fiery kick, add more chili sauce or a pinch of crushed red pepper flakes.
Is this dish suitable for gluten-free diets?
Yes! Simply swap out regular soy sauce for tamari and use gluten-free rice noodles. This way, you keep all the flavors intact while making it safe for gluten-sensitive eaters.
Can I add protein to make this a more substantial meal?
Definitely. Adding grilled chicken, tofu, shrimp, or even edamame can turn this into a heartier meal. Just cook your protein separately and toss it in with the noodles and sauce at the end.
What other vegetables can I add for variety?
Shredded carrots, bell peppers, snap peas, or even thinly sliced radishes add delightful crunch and color. Feel free to mix and match according to what you have on hand or seasonally available.

This Spicy Peanut Noodles with Cucumber Recipe brings together so many incredible flavors and textures in a dish that’s truly moreish and easy to make.
