I have cooked with many peppers since living in Austin, but never shishito peppers. It is really easy to cook shishito peppers and they are easy to use in so many recipes!

Why This Soup Is Great:

  1. Shishito peppers are becoming more popular because of their mild peppery flavor. Only 1 in 10 shishito peppers are spicy, but I think that is a bit off. I have rarely bitten into a super spicy shishito pepper.
  2. Roasted shishito peppers almost caramelize when blistered. It makes this chilled soup absolutely delicious.
  3. This chilled pepper soup is perfect for hot summer days!
  4. You can make this soup ahead!

Ingredient Notes:

  • Shishito Peppers – These little peppers are at many grocery stores and farmer’s markets. Trader Joe’s carries them all year round now!
  • Cucumber – I used Persian cucumber because it doesn’t have big seeds.
  • Onion – You can use sweet yellow onion or red onion in this recipe.
  • Garlic – Fresh garlic cloves really taste best.
  • Apple Cider Vinegar – This gives the soup a nice tanginess.
  • Vegetable Stock – You can use low-salt vegetable stock or water.
  • Salt – I used sea salt, but kosher salt also works well.

Recipe Step By Step Directions:

Charring shishito peppers in a frying pan.

Step 1: Heat a cast iron skillet on medium-high heat and add the oil, garlic, and shishito peppers. Char the peppers in the pan until the skin is blistered with black spots and the peppers are softened.

Step 2: Add all ingredients to a Vitamix or high-powered blender. Be sure to remove the stems from the peppers before adding them.

Many people only use their Vitamix for smoothies, but you can make amazing soups with a Vitamix.

Step 3: Blend the ingredients for 30 seconds until the soup is smooth. Place the soup into an airtight container. Refrigerate the soup for 2 hours until chilled.
