Instant Pot Fish from Frozen

This Instant Pot steamed white fish recipe is the easiest way to cook fish. Not only is it easy, but it comes out tender, flaky, and perfect in less than 15 minutes. Oh and did I mention that you can cook cod, tilapia, or halibut this way from frozen? No need to plan ahead or defrost it before cooking.

Notes

  • Use your favorite white fish (cod, tilapia, halibut). It probably works with salmon too, I just haven't tested it for time)
  • If fish isn't done, set timer for a couple extra minutes to finish cooking. It usually gets up to pressure more quickly if it's just been used.
  • Herb Couscous recipe.
