🍲 Ingredients
Udon Noodles – Udon noodles are a thick noodle made from wheat flour, often used in Japanese cuisine. It is known to be a Japanese comfort food and in moderation they provide a healthy dose of carbs and fiber. Their thick, chewy texture makes them perfect for holding onto that rich peanut sauce, creating the ideal bite every time.
Peanut Sauce – I like a creamy salad so I do add 1/2 cup to this but if you prefer less just adjust as you toss and taste! This rich, velvety sauce is what transforms simple noodles into something extraordinary. The combination of peanut butter, spices, and aromatics creates a sauce so good you’ll want to put it on everything.
👩🍳 How to Make Spicy Udon Noodles
1. Cook Udon Noodles as per package instructions.
2. Prepare the peanut sauce.
3. To a large bowl, toss together the udon noodles, sauce, peppers, and cilantro. Serve as is or with protein of choice.

🪄 Tips and Tricks
- Noodle Texture: Don’t overcook the udon noodles – they should be tender but still have a slight chew.
- Sauce Temperature: Let the peanut sauce come to room temperature for easier mixing, or thin it with a splash of warm water.
- Tossing: Use tongs or chopsticks to ensure the sauce coats every noodle evenly.
- Serving: This dish is delicious both warm and at room temperature, making it perfect for meal prep.
🗒 Substitutions
- Noodles: Can I use different noodles? Udon noodles are great here but you can use ramen noodles or even pasta! A thicker noodle is encouraged for this udon noodle recipe.
- Vegetables: Use any vegetables you want in this dish. You can add as many or as little as you’d like it’ll still taste great! Try broccoli, snap peas, carrots, mushrooms, or edamame.
- Cilantro: I know not everyone is a fan of cilantro so you can totally omit this. However, if you do like this herb, it adds a fresh flavor to it and I would definitely keep it in. Green onions or Thai basil make great substitutes.
- Protein: Add grilled chicken, tofu, shrimp, or edamame to make this a complete meal.

👝 How to Store Leftovers
Store any leftover sauce in a jar in the fridge for 10 days. The tossed salad will last up to 1 week in a tightly sealed container. When reheating, add a splash of water or broth to loosen the sauce, as it may thicken when cold. This dish is also delicious served cold as a noodle salad.
