Ingredients

  • 14 oz udon noodles
  • 1 medium red pepper diced

Peanut Miso Sauce

Optional Toppings

Instructions

  • 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 tablespoon of oil to help them crisp up).
  • Mix miso peanut sauce ingredients in a blender or whisk until smooth. It the sauce is too thick, add 1-2 more tablespoon of hot water until desired consistency.
  • Toss your cooked noodles, red pepper, and sauce together in a large bowl.
  • Serve with toppings like crushed peanuts, diced green onion, sesame seeds, lime, or red pepper flakes!
  • Store miso peanut noodles in an airtight container for up to 3-4 days.

Notes

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
  • This dish is easily customizable! Add in any other veggies you like such as snap peas, onion, broccoli, kale, spinach, other peppers, and more!
  • Add some protein with tofu (such as my Crispy Asian Tofu) or tempeh.
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.
FAQ:
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 miso peanut noodles 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.
