Why You'll Love This Recipe

  • This recipe is ready in 20 minutes, so it's the perfect weeknight dinner recipe.
  • And it makes great use of simple pantry ingredients.
  • These Peanut Udon Noodles are flavorful, spicy, and completely vegan!
  • This recipe is packed with vegetables like cabbage and carrots.
  • And most importantly, it is absolutely delicious!

Ingredient Notes

Ingredients for this recipe in small bowls on a linen cloth.

Fresh or Frozen Udon Noodles: Fresh or frozen udon noodles are way bouncier and chewier than their dried counterparts, so I highly recommend taking a trip to your local Asian market to grab some. Personally, I love frozen udon noodles because they keep longer and have fewer ingredients.

Creamy Natural Peanut Butter: Your peanut butter should only have peanut and salt in it for this recipe! The kind that has added sugar is too sweet for this recipe.

Sambal Oelek: Sambal Oelek is a spicy ground chili paste. It adds a little spicy flavor to these Vegan Peanut Udon Noodles.

Unseasoned Rice Vinegar: I always keep unseasoned rice vinegar in my pantry. It is great for making vinaigrette, or a quick sauce to dip dumplings into, or a quick peanut sauce like this recipe!

Soy Sauce: I used lower-sodium soy sauce for this recipe. Tamari or shoyu will also work!

Vegetables: This recipe uses ginger, garlic and, green onions for flavor, and cabbage and carrots for some veggies!

How to Substitute Dry Udon Noodles

Fresh and frozen udon noodles already have water in them, while dry noodles don't, so the weight of noodles you should use is very different!

This Vegan Peanut Udon Noodles recipe calls for 20 ounces of fresh or frozen udon noodles. If you use dry noodles, use 8 ounces.

Instructions

Garlic, ginger and green onion in a skillet.

Step 1. Heat olive oil in a 10 to 12-inch stainless steel skillet over medium heat.

Add the garlic, ginger, and sliced green onions and cook, stirring frequently until fragrant, about 1 minute.

Cabbage and carrots added into aa skillet on a stovetop.

Step 2. Next, add the shredded cabbage and carrot and cook, stirring frequently, for 2 minutes.

Then, add the soy sauce and use a wooden spoon to scrape any bits up that are stuck to the bottom.

Cook for about 2 more minutes, until the cabbage has softened.

Peanut butter sauce added into the skillet.

Step 3. Add peanut butter, rice vinegar, sambal oelek and ยผ cup of water and stir until a creamy sauce forms.

Udon noodles added into the skillet.

Step 4. Remove from heat and add cooked udon noodles. Use tongs to toss everything together, adding additional water if needed to thin the sauce out.

Serve with green onion tops and crushed peanuts.

Recipe FAQs

How should I store these Vegan Peanut Udon Noodles?

Store any leftover noodles in an airtight container for up to 4 days.
To reheat, place some noodles in a skillet, add a little water to loosen the sauce, and heat until warm.

What is the difference between ramen noodles and udon noodles?

Ramen noodles are much thinner than udon noodles. Udon noodles are thick, bouncy, and plump.

Should I rinse udon noodles after cooking?

Yes! It is important to rinse the excess starch off the noodles so they don't clump together.

Expert Recipe Tips

If you can't find udon noodles, you can substitute 8 ounces of soba noodles, or even ramen noodles!

If you hate chopping, you can use coleslaw mix in place of the shredded cabbage and carrots in this Vegan Peanut Udon Noodles recipe! Use about 3 cups.

I used ยฝ cup of water in total to thin the peanut sauce out. You may need a little more or less, depending on the heat of your skillet!

Notes

I like frozen udon best because it keeps much longer!
To substitute dry udon noodles, or even dry soba noodles or dry ramen noodles, use 8 ounces instead of 20 ounces.
Instead of chopping your own cabbage and carrots, you can use coleslaw mix!
