  • 3.1 oz soba noodles 1 round of noodles

Spicy Sauce:

  • 3 tbsp fresh lime juice
  • 1 pinch lime zest
  • 2 tbsp tamari sauce or soy sauce
  • 1 knob raw ginger about 1 Tbsp - peeled + microplaned
  • 1 tsp red pepper flakes or red chili paste
  • 1 tbsp creamy peanut butter softened
  • 3 tsp maple syrup or agave, brown sugar or coconut sugar
  • a few pinches cayenne or black pepper - optional
  • 1 tsp sesame oil or olive oil - optional

Fold in:

  • 1 handful baby spinach finely chopped
  • 1 slice lime chopped peanuts - optional


  • Bring a medium pot of water to a boil. Add in the soba noodles. I like to break the noodles in half before boiling so they are easier to eat.
  • While the noodles boil, whisk together the sauce. Add all the ingredients to a mug or small bowl and whisk until smooth. It is important that the peanut butter is nice and oily and soft so that it whisks smoothly without clumps. If you peanut butter is hard or clumpy, you may want to warm in the microwave or even add a spoonful of oil to it to soften a bit.
  • Noodles should be fully cooked in 4-5 minutes. Drain water and bounce noodles around in a strainer to remove all excess water. If you like really dry soba noodles you can even squeeze them very gently with a few clean paper towels. (I usually skip this step, but you also don't want watery noodles being sauced to water down the flavors.)
  • Pour the noodles into a clean mixing bowl. Fold in the sauce. Start with 3 Tbsp sauce and add more as desired. Toss noodles well until coated.
  • Fold in the chopped spinach to gently wilt it.
  • Transfer noodles to serving bowls. Garnish with optional chopped peanuts and a slice of lime. Serve warm. Leftover can be covered and chilled in the fridge for up to two days. These noodles actually taste delicious served warm or chilled.
