I'm so excited to share this Whole30 Instant Pot seafood gumbo with you! It comes bursting with flavor and delicious ingredients like sea bass filets, bell peppers & shrimp! It's the perfect one pot meal to add into your rotation and is dairy free, paleo and low carb.

An easy seafood gumbo recipe made in the famous Instant Pot
I feel like I am always one of the last people to jump on the "trending" bandwagon, and that has been made evident by how long it has taken me to finally start using my Instant Pot.
I bought it nearly two years ago, but it's been sitting in my cabinet collecting dust with the exception of a few bone broth making sessions. I'm the worst.
I'm happy that I finally took it out of the cupboard and decided to make this easy seafood gumbo recipe inside of it. You really can't go wrong with making gumbo, as there are so many different types of protein you can add inside depending on your taste preferences.
I found that adding in the sea bass was the perfect way to get in an extra dost of omega-3's, coupled with wanting to support sustainable seafood practices. I highly recommend getting on the gumbo train because it's a delicious and joyous ride.
Another way to customize this recipe would be to add cooked cauliflower rice or white rice inside of the gumbo.
I decided to leave it out because I knew there would be days I'd want to eat it sans the rice, but a traditional gumbo recipe would have rice inside of the stew. You really cannot go wrong either way!

Do I need to use sea bass in this gumbo recipe?
Sea bass is not a fish that is easy to find from a sustainable source, so if you can get your hands on some, please do! 🙂 By the way, did you know that sea bass has the highest amount of omega-3's found in any white fish?
Hey, why wouldn't we want to support our brains and cardiovascular health?!
I love how meaty the texture is, while the flavor remains buttery... sea bass reminds me a bit of grouper or halibut, but it isn't overfished like they are.

Can I make this gumbo on the stovetop instead?
Absolutely. I've provided instructions on how to do so in the notes section! 😉
The fact that I made this easy seafood gumbo recipe in such a quick amount of time and in one pot is so dang impressive.
I thought that the shrimp and fish would come out dry and overcooked, but I was boldly mistaken- and thank goodness for that!
My husband let it be known *after trying this gumbo* that he thought it tasted very healthy.
Immediately, I felt pretty offended and alarmed by this statement, but he told me to rest assured that it was actually a good thing.
Usually eating a seafood gumbo will leave you feeling quite heavy and groggy afterwards. Guess what thought? You will NOT feel any of those feelings *or any other unpleasantries* after chowing down on a bowl of this gumbo.

How to make Instant Pot Seafood Gumbo
Season the barramundi with some salt and pepper, and make sure they are as evenly coated as possible. Sprinkle half of the Cajun seasoning onto the fish and give it a stir- make sure it is coated well and set aside.
Put the ghee in the Instant Pot and push "Sauté". Wait until it reads "Hot" and add the barramundi chunks. Sauté for about 4 minutes, until it looks cooked on both sides. Use a slotted spoon to transfer the fish to a large plate.
Add the onions, pepper, celery and the rest of the Cajun seasoning to the pot and sauté for 2 minutes until fragrant. Push "Keep Warm/Cancel". Add the cooked fish, diced tomatoes, tomato paste, bay leaves and bone broth to the pot and give it a nice stir. =
Put the lid back on the pot and set it to "Sealing." Push "Manual" and set the time for just 5 minutes! The Instant Pot will slowly build up to a high pressure point and once it reaches that point, the gumbo will cook for 5 minutes.
Once the 5 minutes have ended, push the "Keep warm/Cancel" button. Cautiously change the "Sealing" valve over to "Venting," which will manually release all of the pressure. Once the pressure has been release (this will take a couple of minutes), remove the lid and change the setting to "Sauté" again.
Add the shrimp and cook for about 3-4 minutes, or until the shrimp have become opaque. Add some more sea salt and black pepper, to taste. Serve hot and top off with some cauliflower rice and chives.

Get creative with protein swaps in this seafood gumbo!
Gumbo goodness- say that 12 times over and over again. It sounds pretty catchy, actually. I'm seriously so darn happy the weather is slowly but surely cooling down here in Southern California.
I'm a huge fan of all of the coolness the Fall and Winter months bring to the table. That means that I get to make and eat all of the soups and stews.
In fact, I'm probably going to end up matching this seafood gumbo again next week and throwing it into the freezer. Why not?!
As I mentioned before, you can get as creative as you'd like with this gumbo goodness. If you're not into shrimp, I'd recommend replacing it with some compliant sausage of some sort.
That's what usually comes inside of traditional gumbos, and there is great reason for that. Let's get to it, shall we?

- If you're going to make this recipe on the stove top, start by browning the sea bass in a large saucepan and transfer it to a plate with a slotted spoon. Add the onions, peppers, and celery, and cook for approximately 5 minutes. Add the browned fish, tomatoes, broth, and bay leaves into the saucepan and bring to a simmer. Let this stand and cook for about 30 minutes. Add the shrimp just a few minutes before you plan on serving the gumbo. Simply add them to the stew and cook for 3-4 minutes until they are opaque throughout. Season with salt and black pepper, to taste. Serve warm.

Hi!
If you're adding rice directly into the recipe, do you just add it when you add all the other ingredients, or should you cook it first and mix it in at the end?
May be a silly question, but I wasn't sure.
Thanks!
saz says
Also (sorry), how much rice is appropriate to add to this recipe's proportions?
Good question!!!! If you are adding rice, I'd add already cooked rice! I'd add maybe 3 cups total!
Lr says
I added a box of rice and broth in the amount required and it boiled it right up!
Kris says
What is a good replace fish for sea bass?
Any white fish would be okay!
Elisha says
My family loved this recipe. I halved it and it was enough for my family of five With leftovers! We aren’t heavy eaters though. One small modification is that I didn’t have tomato paste so I used the full 28 ounce can of crushed tomatoes and let it simmer down Just a bit after the last step. I also used cauliflower rice in each bow which thickened it up a bit. Great recipe. Loved it!
Cathy Williams says
In your ingredients you list "bone broth". Hate to be picky but is that beef or chicken bone broth? Please, no rude comments about I should know what Monica means.
Hi there. Aw, you are so sweet. I typically use chicken, but you can honestly use either... even chicken broth!
Christie Smith says
I’m so thankful I came across this recipe! My hubby and I have enjoyed this seafood gumbo several times. Very tasty, and healthy. I’ve also added scallops to the recipe.
That is GENIUS. I may need to try it with scallops, too! 🙂
Danielle says
When do you add the scallops? Same time as fish or shrimp?
Hi there. Scallops aren't a part of the recipe, but if you want to add them, you should add them the last few minutes as they cook VERY quickly.
Aaron McCracken says
Absolutely excellent. We used fish stock instead of bone broth, cod instead of sea bass (availability), and I would recommend adding andouille sausage. Loved it and it is now part of our monthly menus
Yay, Aaron. That makes me so happy!!! Feel free to rate the recipe (using the star system on the recipe card itself)... it helps myself and my readers out tremendously. Oh, and do let me know what you make next! 🙂
Aaron McCracken says
You should definitely try some carnitas in the instant pot. They are my second favorite thing to make (gumbo first). I’m looking for an all instant pot recipe for lengua tacos now so if you happen to make one please let me know
Jenn says
I made this tonight and it was a hit! I’m new to using the Instant Pot so followed your instructions precisely and it turned out delicious.
That makes me so happy to hear! I'd love if you could rate the recipe (using the star system on the recipe card) if you have a moment. It helps me and my readers out tremendously. That Instant Pot is a game changer, huh? 🙂
mARY c says
Is there something I can use instead of bone broth? I am pescatarian,
You can absolutely use veggie broth!
Brenda Russell Payne says
Wow!! This is so good!! I added a few things as I thought it needed a little depth of flavor. I used a few dashes of chili powder, smoked paprika, fresh basil, onion powder, garlic powder and a few red pepper flakes. It was a hit. Will certainly be in the dinner rotation from now on!!
I love, love, love that you made it your own!!! Sounds fabulous with those additions.
Num Yummy Butter says
We made this tonight and it was *perfect*. CostCo was out of sea bass so we used scallops instead, but this turned out absolutely amazing! Thanks for sharing, this is definitely going into our low carb comfort food rotation.
I LOVE THAT. Oh my gosh, scallops? THat's definitely more luxurious than my recipe. SO happy you enjoyed it-- I have a low carb cheeseburger soup that is fabulous as well 🙂

I've recently switched to a pescatarian diet, and my parents were skeptical of preparing a meal that they could share with me that adhered to my restrictions (especially with them both being southern, and meat being a staple within any gumbo/seafood recipe...I compromised by offering some cornbread on the side). I found this recipe and offered to make it with their new Instant Pot, and it was a HIT! This is so packed with flavor and is absolutely delicious. They were talking about it days later. This gumbo is so good that I've scoured the internet to find it again so I can prepare it for myself and my boyfriend this evening. Thanks so much for this recipe!
This makes me so, so happy to hear. I'm so happy you loved it! 🙂
