How To Make Instant Pot Tilapia Fish Tacos

STEP ONE: Place your frozen tilapia fillets on a sheet of aluminum. Sprinkle each fillet with taco seasoning. You can try our mild taco seasoning recipe here.

STEP TWO: Seal your aluminum foil from each side.

STEP THREE: Add 1½ cups of water to the bottom of your Instant Pot, then place the trivet inside. Set the wrapped tilapia fillets on top of the trivet.

STEP FOUR: Close the lid of your Instant Pot and set the valve to sealing by pushing away from you.

STEP FIVE: Set your Instant Pot to high pressure for 18 minutes.

STEP SIX: Once the cooking time is complete, turn the valve to venting, or towards you, for a quick release.

STEP SEVEN: Once the pressure gauge drops, unlock and remove the lid, then carefully remove the foil packet of tilapia.

STEP EIGHT: Open the packet and shred your tilapia, then place on your favorite taco shell (whether it be a low carb tortilla, lettuce wrap, flour tortilla, or corn!) Top with the aïoli sauce, cilantro, and anything else you would enjoy on your fish taco. Enjoy!

How To Make Garlic Aïoli Sauce

STEP ONE: In a small bowl, add the mayonnaise, minced garlic, lemon juice, lemon zest, and a dash of salt and pepper.

STEP TWO: Mix the aioli until well-combined.

STEP THREE: Cover and refrigerate until you’re ready to serve.

Toppings For Your Tilapia Fish Tacos

Half the fun of tacos is adding all of your favorite toppings! If you need a little inspiration, here are a few of my favorites:

• Cilantro
• Avocado Crema
• Chopped tomatoes
• Cabbage
• Shredded cheese
• Diced onion
• Jalapeño slices
• Avocado
• A squeeze of lime

Can You Make This Recipe With Fresh Tilapia Instead Of Frozen?

Absolutely! This recipe works just as well with fresh fish. It’ll cook up a little faster, too.

Follow the same directions to season the fish, wrap the fillets in tin foil, and prepare the Instant Pot.

Then, simply adjust the cooking time to 8 minutes. Once the cooking time is complete, do a quick release and follow the rest of the recipe as usual.

How Do I Safely Quick Release My Instant Pot?

When you let the pressure in the Instant Pot release on its own over time, this is called a “natural release.” To immediately remove the pressure, you can do a “quick release.”

To safely quick release the pressure in your Instant Pot:

• While wearing an oven mitt or heat resistant glove, turn the valve towards you to venting. Be careful not to burn your arm or hand as it will release a lot of steam very quickly.

• Make sure there is plenty of room for your pressure cooker to release the steam. If it’s under any cabinets, turn it so the steam is not trapped.

• If the valve is spraying water, try closing it for 15 to 20 seconds before opening it again. Repeat until the valve is no longer spraying.

• You’ll know it’s safe to unlock and remove the lid once the pressure gauge drops.

How To Warm Up Tortillas For Soft Tacos

Who doesn’t love warm tortillas for their tacos? While the fish is cooking, here’s how you can get the soft shells ready:

1. Preheat the air fryer to 350 degrees or the oven to 400 degrees.
2. Wrap the tortillas in foil.
3. Place in the air fryer for about 5 minutes or in the oven for about 10 minutes.
