Easy Peanut Udon Noodles (lazy dinner!)

These easy peanut udon noodles are the perfect lazy dinner for when you need something yummy and quick. What could be easier than boiling noodles, whisking a sauce together and combining them? If you want extra crunch and volume, try my hack of spiralizing cucumbers and adding them to the noodles.

What ingredients are needed?

The ingredients for this recipe are super simple. Grab your favorite type of noodle: I love udon noodles in this recipe! You don’t need to go to any special grocery store to find them, I got mine at Trader Joe’s and I have even found them at Publix.

You need the sauce ingredients: the base is peanut butter. Most of the ingredients in the sauce are pantry staples like soy sauce, rice vinegar and toasted sesame oil.

Furthermore, for the garnish you need sesame seeds and scallions.

  • Udon noodles: if you can find thick cut udon noodles, those are the best in this dish! Otherwise, use what you can find, it will all taste yummy!
  • Cucumber: I like hot house cucumbers because the peel is less thick and more edible.
  • Sesame seeds: these make the perfect garnish when the dish is complete. I used both black and white sesame seeds but use whatever you have on hand.
  • Scallions: this adds great flavor in the garnish
  • Tofu: optional protein

Peanut Sauce Ingredients:

  • Peanut butter: get unsweetened, all natural creamy peanut butter
  • Soy sauce: this adds a classic flavor to these noodles
  • Toasted sesame oil: get toasted not regular sesame oil, it has a much richer, distinct flavor
  • Sriracha: this adds a little heat!
  • Rice vinegar: sub lime juice if you can’t find it!
  • Ginger: use fresh or powdered
  • Garlic: use freshly minced or powdered

Allergen Substitutions:

Noodles: if you are gluten-free, use thai rice noodles!

Soy sauce: do you have celiac or are you gluten intolerant? Use tamari. If you are soy-free use coconut aminos.

Peanut butter: use tahini as a great peanut butter substitute if you have a peanut allergy

Important tips for success:

Use my personal hot tips for making sure this turns out great.

Do not overcook the noodles! Typically, thick-cut udon noodles only take 3 minutes so don’t overcook. They will get mushy if you cook them too long.

Save the pasta cooking water. The recipe calls for hot water in the sauce to thin it out, save the pasta water for this to add into the sauce.

Make crispy tofu. Air-frying tofu is an amazing cooking secret to make it crispy but for the saute method that I used, just saute on both sides in a non-stick pan until golden brown. If you don’t have an air-fryer simply pan fry until golden brown on each side or bake in the oven.

New peanut butter: it is easier to stir runny fresh peanut butter from a new jar instead of hard peanut butter that’s been in the fridge.

  • Bulk this up with lots of veggies if you want! Add in some sautéed mushrooms, shredded carrots, bok choy, peppers, or even spinach!
  • Don’t like noodles? Make this with veggies, tofu and rice instead. Instead of mixing the sauce with the rice, drizzle on top if you choose this method.
  • Not a fan of tofu? Add tempeh to this for extra protein!

    How long and at what temp do you air fry thin strips of tofu? Do you spritz with oil?

    1. Taylor From HealthyGirl Kitchen says:

      Every air fryer is different, but typically for 20 minutes at about 425F giving them a shake halfway through. Yes, spritz with olive oil.
