  • 2 cups water
  • 2- inch piece kombu
  • 1/2 cup loosely packed dried bonito flakes katsuobushi, optional
  • ¼ onion thinly sliced
  • 1 cup oyster tree mushrooms
  • 1 medium zucchini spiralized
  • ½ tbsp pink salt
  • 1 package Wild-Caught Icelandic Cod
  • 2 tablespoons oil; avocado or olive
  • bonito flakes
  • toasted sesame seed oil

For the pasta and cod:

  • 4 cups cooked pasta of choice
  • 3 tablespoons pesto
  • 2 tablespoons ricotta cheese
  • 4 cups reserved water from pasta boil
  • 1 package Atlantic Wild-Caught Cod Fillets
  • 2 tablespoons olive oil
  • Salt + Pepper to taste


For the Dashi:

Combine the water and kombu in a 1-quart saucepan and set over medium heat. Remove the kombu from the water just before it comes to a full boil. (Boiling the kombu can make the broth bitter and a bit slimy.) Add the bonito flakes, if using, and let the water come to a rapid simmer. Continue simmering for about 1 minute. Remove the pan from heat and let the bonito steep in the broth for an additional 5 minutes. Strain the bonito flakes from the broth. Add 2 cups water, pouring through the strained bonito. Heat saucepan on a medium to low heat. Add salt, onion, zucchini noodles and mushrooms. Simmer for 10 minutes.

For the Baked Cod:

While the soup is cooking, preheat oven at 400F. Coat Cod with avocado oil and season with salt. Place cod in oven and bake for about 10-12 minutes. When ready, take out of the oven and let it sit. In a bowl, plate onion, zucchini, and mushrooms first. Top with a Cod fillet and gently pour broth. Garnish with bonito flakes and toasted sesame seed oil.
