You first need to find a small glass dish that can fit in the Instant Pot.
Once you find the dish, pour in the Cherry Tomatoes.
Cut your Alaskan Cod fillet into small pieces. Three small pieces should be fine.
Put the fish pieces over the top of the Cherry Tomatoes.
Add in seasonings, such as salt and pepper.
Add in the two tablespoons of butter. Drizzle some Olive Oil on the top if you wish.
Add one cup of water inside of the Instant Pot. Put the trivet inside of the pot.
Put the glass dish on the top of the trivet. Close the Instant Pot lid and seal the valve.
Put your Instant Pot on "Manual" high pressure and set the timer for five minutes. If it is still frozen cod, set the timer for nine minutes.
Allow pressure to release naturally after the time is up.
