Miso is an edible paste made from fermented soybeans and barley or rice malt used most commonly in Japanese cooking. It is most well known in miso soup but has been popping up in the food scene more often. Miso is associated with certain health benefits such as lower cholesterol levels (when consumed instead of animal products) and better nighttime blood pressure control in those with stage 1 hypertension.

Miso has a savory umami flavor, which in Japanese translates to “deliciousness.” It is one of our five primary tastes. Combined with creamy avocado and flavorful herbs, this miso sauce achieves a richness despite being completely plant-based. The plant-based diet touts many ​benefits, which may include preventing chronic diseases such as diabetes and hypertension.


  • 4 oz. whole wheat spaghetti
  • 2 medium zucchini
  • 1 cup canned low sodium chickpeas
  • 1 tbsp. olive oil
  • 1/2 tsp. paprika
  • 1 small avocado, about 1/2 cup mashed
  • 1/2 cup cilantro
  • 1/2 cup scallions
  • 2 cloves garlic
  • 2 tbsp. lemon juice
  • 1/4 tsp. salt
  • 1/4 tsp. pepper
  • 1 tbsp. miso paste
  • 4-8 tbsp. water


  1. Preheat oven to 400 F.

  2. Toss chickpeas with olive oil and paprika. Roast for 20 minutes, flipping halfway through.

  3. If your zucchinis aren't already in noodle/spiral shapes, then use your spiralizer appliance to cut your zucchini.

  4. Cook spaghetti according to package directions.

  5. Add avocado, cilantro, scallions, garlic, lemon juice, salt, pepper, and miso paste into a blender. Blend until smooth. Add water 1 tablespoon at a time until sauce reaches desired consistency.

  6. Lightly spray a large pan with spray oil. Add zucchini and cook on medium heat for a few minutes until soft.

  7. Drain spaghetti and add into the pan with zucchini. Add sauce and mix well. Add the chickpeas last.

Variations and Substitutions

This recipe is best when miso is used. But if you don't have any on hand, some cooks find that soy sauce or fish sauce provides an equivalent taste.

If you don't want to use whole wheat spaghetti or zoodles in the proportions listed, use your favorite blend of pasta and veggie noodles. For instance, you might try butternut squash noodles, summer squash noodles, or carrot veggie noodles. Perhaps blend a few different options and throw some daikon radish noodles in at the last minute for an extra bit of crunch.

Cooking and Serving Tips

  • Pre-spiralized zucchini will save the most time, however, a spiralizer tool is easy to use and can be purchased for about $30. You can also use a peeler tool to create a ribbon shape.
  • Make a larger batch of roasted chickpeas and save them for later. Add them to salads or soups for a bit of spicy crunch.
  • You can also make some extra sauce and save it in the refrigerator for up to a week. Use it on top of other pasta dishes or drizzle it on grilled poultry, seafood, or tofu.
