Spicy Peanut Sauce

  • 2 small cloves garlic
  • 2 tsp miso paste white or yellow
  • 2 Tbsp rice wine vinegar
  • 2 Tbsp tamari or soy sauce
  • 3 heaping Tbsp creamy peanut butter
  • 1 tsp sriracha
  • 1 tsp fresh ginger grated
  • 1 lime juiced
  • 1 tsp maple syrup or agave nectar
  • 1/2 cup hot water


  • 2 bundles soba noodles
  • 2 carrots
  • 1 daikon radish small
  • 1/4 purple cabbage thinly sliced
  • 4-6 baby bok choy thinly sliced lengthwise
  • 2 scallions thinly sliced

Garnishes (optional)

  • roasted peanuts
  • sesame seeds
  • chopped cilantro


  1. In a small bowl add all the sauce ingredients except the water and mix together. Whisk in the hot water until you get a smooth textured sauce. If you want it to be thinner add a few tablespoons of hot water, if you want it to be thicker add another tablespoon of peanut butter. Set Aside.*
  2. Prepare a large bowl full of ice then cover with cold water, set aside.
  3. Fill a medium sauce-pot with water and bring to a boil. Add the carrots, daikon, cabbage and bok choy and blanch for 30 seconds. Using tongs remove the vegetables and shock them in the ice water to stop the cooking process. Once cool, remove from the ice and place on a plate with a towel to get rid of the excess water. This quick cook will bring some nice color to the vegetables. 
  4. Add the noodles to the pot of boiling water and bring the heat down to medium low.* Cook the soba noodles according to the instructions on the packet, should take around 5-7 minutes depending on the brand and thickness of the noodle. When cooked through but not mushy, drain and immediately rinse with cold water, set aside.
  5. Pace your soba and vegetables into bowls and serve with the peanut sauce. Top the bowls with your choice of cilantro, crushed peanuts or sesame seeds. This dish would also be great with some fresh edamame! 

Recipe Notes

*If you do not like small pieces of garlic or ginger in your sauce you can always blend it!

*When cooking soba noodles, if the pan is not big enough or if the temperature gets too hot it sometimes will boil over with starchy water, just be careful to watch your noodles.  If you need to turn down the heat or add some cold water go ahead. 

* If you can't use peanuts this sauce would be just as delicious with some almond butter.
