Here’s how to make a delicious Instant Pot Mahi Mahi Stew using fish, coconut milk, and chopped vegetables. This easy and healthy dinner recipe can be made in just 25 minutes. This is a great recipe for busy weeknights.

  • Total Time: 25 minutes
  • Yield: 4 1x


Units Scale
  • 2 Mahi Mahi fillets (about 10 ounces total), cut into bite-sized pieces
  • 2 bell peppers, cored and chopped into 1-inch pieces
  • 1 onion, chopped
  • 1 13.5ounce can full-fat coconut milk
  • 1 cup reduced sodium vegetable broth
  • 2 tablespoons coconut sugar
  • 1/2 teaspoon sea salt
  • 1/4 teaspoon ground black pepper
  • Cooked rice or cauliflower rice, for serving


  1. In the bowl of a 6-quart or 8-quart Instant Pot, combine the chopped fish, bell peppers, onion, coconut milk, vegetable broth, coconut sugar, sea salt, and black pepper.
  2. Lock on the lid and set the time to 5 minutes at high pressure.
  3. When the cooking time is up, use the quick-release to get rid of the pressure.
  4. Carefully remove the lid and stir the ingredients.
  5. Serve the Coconut Fish Stew hot, over your choice of cooked white rice, brown rice, or sautéed cauliflower rice. 


  1. You can use whatever white fish you like for this recipe including Mahi Mahi, halibut, cod, or even salmon. 
  2. You can use light coconut milk, if you prefer. 
  3. Leave out the coconut sugar if you are on a low-sugar, low-carb, or Whole30 diet. 
  4. Feel free to serve your cooked fish with a squeeze of fresh lemon juice, if desired.
  5. If you don’t have vegetable broth, feel free to use chicken broth or even a cup of water instead.
