These noodles are SO flavorful and may be one of my favorite Asian dishes I’ve ever made. It has fairly simple ingredients; the miso is the unique flavor addition to this sauce that really deepens the sauce.

If you love the savory umami flavor of miso, you will go crazy for my Miso Dumpling Soup!

Ingredients:

Udon noodles: These are a type of thick, chewy wheat noodles that originated in Japan. You can find them at most grocery stores in the pasta or Asian aisle. For another delicious noodle dish, try out this Vermicelli Noodle Bowl!
Red Bell Pepper: Dice into small pieces for a pop of color in your noodle dish!

Sauce Ingredients:

Peanut butter: I recommend a natural peanut butter that is smooth and creamy.
White miso paste: Miso paste adds a umami flavor to this dish. It can be found in the refrigerator section at some groceries sometimes (sometimes you have to go to a health food store to find it).
Soy sauce: Adds some saltiness to this dish. You can use low sodium soy sauce if you want to decrease your salt intake. For a gluten-free version use tamari or coconut aminos.
Rice vinegar: Adds a balance of sourness to the sweet and salty.
Sesame oil: Just a splash adds a ton of flavor to this sauce!
Maple syrup: Adds a slight sweet flavor and balances the umami and saltiness
Garlic: You just need 1 clove of garlic for his recipe, minced.
Ginger: Fresh ginger gives the most potent flavor in this sauce but if you don’t have it you can use it pre-minced (from a tube).

Optional Toppings:

Crushed peanuts
Lime juice
Sesame Seeds
Green onions

What is the difference between various types of miso paste?

There are multiple varieties of miso. All are made from fermented soybeans but they have different flavors.

White miso paste

White miso is made from soybeans fermented with a higher proportion of rice or barley. It has a light yellow or beige color and a mild, slightly sweet flavor. White miso has a shorter fermentation period, resulting in a milder and less salty taste compared to darker varieties. This is the best in this peanut miso peanut noodles dish!

Yellow miso paste

Yellow miso is fermented with a balanced ratio of soybeans and grains. It has a golden color and a medium level of saltiness. Yellow miso offers a well-rounded flavor with a mild sweetness and some nuttiness.

Red Miso Paste

Red miso is made from soybeans fermented with a higher proportion of soybeans and a longer fermentation process. It has a rich, deep reddish-brown color and a robust, salty flavor.

How to Make Peanut Miso Noodles

Step 1: Start by cooking your noodles to package instructions. Meanwhile, in a medium saucepan cook your diced red pepper for 5-6 minutes over medium heat. (Optional: cook with 1 tbsp of oil to help them crisp up).

Step 2: Mix miso peanut sauce ingredients in a blender or whisk until smooth. It the sauce is too thick, add 1-2 more tbsp of water until desired consistency.

Step 3: Toss your noodles, red pepper, and sauce together in a large bowl.

Step 4: Serve with toppings like crushed peanuts, diced green onion, sesame seeds, lime, or red pepper flakes!

Storage

Store miso peanut noodles in an airtight container for up to 3-4 days.

Separate Sauce and Noodles (Optional): You can choose to store them separately which helps maintain the texture of the noodles and prevents them from becoming overly saturated. Store the sauce/dressing in a separate container and combine when ready to eat.

❓Recipe FAQs

Can I use a different type of miso in this recipe?

Yes, you can substitute the white miso paste with a different miso like red or yellow. The flavor profile will differ slightly, so adjust the amount according to taste.

Can I make miso peanut noodles ahead of time?

Yes, you can make them ahead of time. However, it’s worth noting that the texture and consistency of the noodles may change slightly when refrigerated. To preserve freshness, I recommend storing the noodles and sauce separately and combine them just before serving.

Is miso gluten-free?

Most miso paste is not inherently gluten-free because traditional miso paste is typically made from soybeans and grains like rice or barley, which may contain gluten. However, there are gluten-free miso paste options available on the market that are specifically made without gluten-containing grains such as this one here.

How do I make this dish gluten-free and/or oil-free?

To make gluten-free: Choose rice noodles, substitute tamari for soy sauce, choose a gluten-free miso paste like this one here.
To make this dish oil-free: don’t use any olive oil when cooking the red pepper. Omit the sesame oil from miso peanut sauce.

Pro Tips

Use a natural peanut butter that is runny and smooth. If you’re peanut butter is dry (like the stuff at the bottom of the bar) this will not make for good sauce
