Instant Pot® Mediterranean Cod – Instantly Delicious

When I was little, my yiayia used to make what she called, Greek Fish.  Sadly, I do not have her recipe. I do remember that she cooked whitefish in a tomato-based sauce, and it was delicious.  Over the years, I have tried to recreate her recipe and  I feel like the recipe I am going to share is the closest I have come.  I rarely use theInstant Pot® for fish because it is an expensive ingredient and I would hate to waste it on a bad recipe. Now that I have had success with fish in the Instant Pot®, I plan to branch out and try more ideas.
For this recipe, I used frozen cod. We are landlocked, so when I can’t get to the fish market for fresh fish, I prefer using frozen.  Cod is a little sturdier than other whitefish, which can fall apart if overcooked. If you have access to quality fresh cod, it would be even better – the time just needs to be reduced slightly. ​I created the sauce using the saute function.  This allowed me to reduce some of the liquid and concentrate the flavors before adding the fish. Once finished reducing, I simply added the frozen fish pieces, covered them with sauce, and cooked on high pressure for 5 minutes.  If you use fresh fish, reduce the time to 3 minutes. You will know it is cooked, when it flakes easily.
Mediterranean-style Cod in the Instant Pot®
Serves 6

6 pieces of frozen or fresh cod (about 1.5 pounds)
3 tablespoons butter
1 lemon, juiced
1 onion, sliced
1 teaspoon salt
1/2 teaspoon black pepper
1 teaspoon oregano
1- 28 oz. can diced tomatoes


1. Set the Instant Pot® to saute. Melt the butter. Add remaining ingredients, stirring to combine. Saute for 8-10 minutes.

2. Arrange the fish portions in the sauce, using a spoon to cover each piece with some of the sauce.  Lock the lid making sure the valve is in the sealing position.  Set the Instant Pot® to manual-high pressure for 5 minutes (3 for fresh fish).  When finished, do a quick pressure release by setting the valve to venting. Serve immediately with plenty of sauce.

Do you need to thaw the frozen fish or do you put it in the instant pot frozen?

I used pretty thick fish but it got overcooked. I would reduce to 4 mins next time. Also it would be good to post total cooking time, as I mistakenly did not account for the pressurizing time, which I think was around 5 minutes or so.

Made this tonight using Costco frozen cod. Turned out great. I cooked x5 minutes on high pressure, wasn’t done. I did 2 additional 3 minute cooking cycles and it was perfect. The fish was really thick which was probably why I had to cook it longer. Super easy recipe. Thanks
