How To Make Instant Pot Fish Tacos?
Here is a step-by-step guide for your Instant Pot Tilapia Fish Taco recipe.

Step One: First, place your frozen tilapia fillets on top of a sheet of aluminum. Sprinkle each fish fillet with taco seasoning. Seal your foil packet from each side.

Step Two: Place 1 & 1/2 cups of water in the bottom of your Inner pot. Place the trivet inside your Instant Pot. Place your tilapia fillets on top of the trivet. Pressure cook your frozen Tilapia fish on high pressure for 18 minutes.

Step Three: While your fish is cooking, make your aïoli sauce. Combine the mayonnaise, minced garlic, lemon juice, lemon zest, and a dash of salt and pepper. Set aside and refrigerate until ready to serve.

Step Four: Once cooked, do a quick pressure release and remove the tilapia fish from the inner pot.

Step Five: Shred your tilapia fillets, and place tilapia pieces (taco filling) on your favorite taco shell whether it be a low-carb tortilla, lettuce wrap, flour tortilla, or corn!

Step Six: Top it with the aïoli sauce, cilantro, and any other toppings you would enjoy on your fish taco such as tomatoes, cabbage slaw, avocado etc!

Expert Tips For Making Tilapia Tacos
- Fishy Taste: If you are worried about your fish tasting too fishy, you can use a little lemon juice for your fish. Simply sprinkle a few drops over each fillet before adding taco seasoning.
- Using A Basket: If you prefer using a steamer basket for tacos, you can simply place your frozen fish foil packet on top of the steamer basket and cook as usual. The result should be just as flavorful and delicious!
How To Store Fish Taco Mixture
- Refrigeration: Cool the fish tacos mixture to room temperature before storing. Place it in an airtight container in the refrigerator within 2 hours of preparation. Enjoy within 1-2 days for optimal freshness.
- Freezing (for Filling Only): If you’ve made an extra batch, freeze just the fish mixture in a freezer-safe bag or container. Label with the freezing date, and store for up to 1-2 months. Thaw in the refrigerator before reheating.
- Reheating: When ready to enjoy, gently reheat the refrigerated fish mixture on the stovetop or in the microwave. For frozen mixtures, thaw overnight in the refrigerator and reheat thoroughly.
These simple steps keep your fish tacos mixture fresh and flavorful, ready for a quick taco night encore!
What To Serve With Fish Tacos?
These tacos are perfect as the main course, but if you have hungry kids like I do, you’ll need a couple of sides. Here are my favorites:
- Cilantro Lime Rice: Light and zesty rice that balances the flavors of fish tacos.
- Black Beans: Simple and savory, they add a filling component to the meal.
- Guacamole and Chips: Creamy avocado dip with tortilla chips for a fresh, crunchy side.

- Cabbage Slaw: Crisp, tangy slaw with a vinegar or lime dressing enhances the texture of tacos.
- Refried Beans: Creamy beans with a hint of spice are a classic pairing.
