Air Fryer Frozen Tilapia
Ingredients


Tilapia Fish Fillets – This recipe is prepared with boneless tilapia fillets (fresh or frozen). You can also use tilapia steaks or tilapia loins instead of fillets. The time of cooking will be slightly more in this case.
You can replace tilapia with any other firm white fish (snapper, grouper, cod, halibut, pollock, etc.) if you wish to. Adjust cooking time for the steak’s or fillet’s size.
I like to use Tilapia because it’s not expensive, does not taste fishy, and I get frozen fillets easily.
For The Marinade – To marinate the fish, you will need lemon juice, unsalted butter, garlic, hot paprika (or use Kashmiri red chili powder), salt, and freshly cracked black pepper.
Use fresh garlic, which adds the most flavor and complements the butter well.
You can substitute butter with extra virgin olive oil for a healthier or dairy-free alternative.
If unsalted butter is unavailable, use salted butter with lesser salt in the marinade.
You can adjust the amount of lemon juice and paprika per your taste.
Use freshly squeezed lemon juice for the best taste.
Parsley – Finally, garnish it with some fresh parsley. You can also use fresh cilantro leaves instead.
Replace the seasoning with creole seasoning, taco seasoning, lemon pepper, or Italian seasoning for a taste change.
You can also add some grated parmesan cheese to the marinade.
Health Benefits Of Tilapia Fish
Tilapia is a low-fat, low-calorie fish that is rich in protein.
It is a good source of omega-3 fatty acids that benefit heart health.
Tilapia also contains several vitamins and minerals, including selenium, potassium, and phosphorus.
Side Effects Of Eating Tilapia
Eating fish that has not been raised in a clean environment has many side effects; the same goes for tilapia. Therefore, it is important to choose tilapia that has been raised in a clean environment and is free from harmful chemicals.
Tilapia may also contain harmful chemicals such as dioxins and polychlorinated biphenyls (PCBs). These chemicals can build up in the body and may cause health problems.
Eating large amounts of tilapia raised in an unhealthy environment may increase the risk of mercury poisoning. Mercury is a toxic metal that can damage the brain and nervous system. Pregnant women and young children are especially vulnerable to mercury poisoning. Therefore, it is important to limit your intake of tilapia if you are pregnant or breastfeeding.
Some people may be allergic to tilapia. If you experience any allergic reaction after eating tilapia, such as hives, difficulty breathing, or swelling of the face, lips, tongue, or throat, seek medical attention immediately.
How To Make Spicy Lemon Garlic Baked Tilapia
Preheat the oven to 350 degrees F (180 degrees C).
Rinse 8 oz (250 g) of tilapia fillets with water and pat them dry using a paper towel.
Line the tilapia fillets on a 9×13-inch baking tray.
Note – if using frozen fillets, thaw them before using them.

Stir together
- 1 tablespoon lemon juice
- 3 tablespoon melted unsalted butter
- 1 teaspoon minced garlic
- ½ teaspoon hot paprika (or Kashmiri red chili powder)
- ¼ teaspoon salt
- ½ teaspoon freshly cracked black pepper
in a small mixing bowl.


Pour the marinade evenly over the Tilapia fillets.
Arrange 3-4 slices of lemon over the fish.

Keep the tray in the middle rack of the oven and bake uncovered for 10-15 minutes or until the fish is white, opaque, flaky, and fork-tender.

Remove the tray from the oven and garnish the baked tilapia fish with pepper flakes, lemon slices, and chopped parsley (or cilantro), and serve hot.

Pro Tips By Neha
This recipe can be easily doubled or tripled.
Make sure to dry the fillets after rinsing them. You can dab them with a kitchen towel to remove the extra water.
Try to use same-size fish fillets for uniform cooking.
Do not overcook the fillets; they will turn chewy if overcooked.
There is no need to flip the fillets while cooking.
You can try swapping the butter with coconut oil, olive oil, etc.
This recipe can be made with chicken as well. The cooking time will be more, though.
Increase or decrease the amount of hot paprika to suit your taste. You can skip it, too, if you dislike spicy food.
You can swap tilapia with any white fish to make this recipe.
If you don’t like spicy, you can replace hot paprika with regular paprika.
If you like the fish tangier, you can use lime juice instead of lemon juice.
Frequently Asked Questions
If you can access fish caught, cleaned, and sold in under 48 hours, you can use the fresh fish.
I like to use frozen because, in most cases, it is processed and frozen almost immediately after it’s caught and is as good as the ones sold at the counter. Plus, you can pull a bag and defrost it, and it’s ready to cook; no need to preplan the shopping.
Put your frozen tilapia, still in its packaging or a plastic bag, in a big bowl and cover it with slightly cold water. Ice-cold water won’t defrost the fish quickly enough, but warm or hot water will mess with the fish’s texture. If the fish is bobbing around, use a weighted bowl to submerge it so that all parts defrost at the same rate.
When the tilapia is farmed properly it is quite healthy. It is high in omega-3 fatty acids and a rich protein source. Before buying the fish, read the label about the fishing practices, fish feed, etc.
The tilapia fillets may vary in size, so baking time slightly varies for everyone.
I bake the fish until the flesh turns white, opaque, and flaky, usually between 15-20 minutes at 350 degrees F (180 degrees C).
If you have a candy thermometer, you can check the internal temperature of fish, and it should be 145 degrees F (62 degrees C).
Check your fish filets after 12 minutes, and if the flesh doesn’t look white and flaky, keep it in the oven for some more time. Do not over-bake the fish; otherwise, it will become too dry and chewy.
This is a great recipe for BBQ. You can wrap the fillets individually in aluminum foil with some marinade and pop the foil packets in the BBQ for 15-20 minutes.
Flip it once midway to ensure the fish is cooked from all sides. If you are going outdoors for a BBQ, these packets are easy to carry.
Butter gives a very delicious taste to this dish, but if you are on a healthy regime, you can replace it with extra virgin olive oil or any other oil you choose. The taste will be very different, but I assure you it will still be delicious.
Serving Suggestions
My favorite way to serve this baked tilapia is over instant pot basmati rice, instant pot brown rice, or instant pot quinoa. Some roasted green beans, cherry tomatoes, Brussels sprouts, roasted zucchini, or roasted broccoli on the side, and you have a healthy dinner ready in no time.
A good option is a delicious pasta, spaghetti, or rice pilaf on the side.
Instant pot garlic mashed potatoes, are also a great side to serve with it.
You can also make tacos using this baked tilapia fillet recipe.
For a healthy meal, serve this oven-baked tilapia and a refreshing salad like this cucumber avocado salad or strawberry walnut salad.
Storage Suggestions
Once the baked fish cools down properly, you can store it in an airtight container in the fridge for 3 to 4 days.
To freeze, arrange the filets in a single layer on a tray and freeze until frozen solid. Then transfer the fillets in a zip lock back. Remove as much air as possible before sealing and freeze for up to a month.
To reheat, just pop the bowl in the microwave for a minute or pop the tray back in the oven for 5 minutes at 200 degrees F.
Thaw the fish if it’s frozen before reheating.

Hi! I just discovered your lovely recipe. Can I use regular butter instead of unsalted? I ran out…Many thanks and continued success!
Neha Mathur

Cecia

Neha Mathur
Yes sure, you can do.
Amanda
Made this tonight.. it had great flavor.. I tripled the recipe bc I had more fish and I used chrushed red pepper flakes instead of the chili powder
Welchella
Can you substitute olive oil for butter? If not, do you have an alternate to butter for use in this recipe? I am excited to try but can’t use butter. Thanks
Neha Mathur
Yes sure. You can do that.
Holly M
This was wonderful! It’s the first time I’ve ever baked fish and not had my house overwhelmed by fish smell! While it was baking, it just smelled of fragrant garlic (I doubled it) and mine cooked through right at 10 minutes.
I had a half a pint of grape tomatoes that were starting to go & needed to use them up. I sliced them in halves and sprinkled them all around the pan before baking. They cooked perfectly and added such a wonderful flavor! I also mixed cilantro with my parsley because I had some chopped. Mmmmmm!
I served mine with some curried couscous. It cooks in 5 minutes and is very light like the Tilapia.
Thank you for so much for the recipe and thank you everyone else for adding their own suggestions. I always read through the comment section first out of curiosity 🙂
Neha Mathur
Wow Holly. Your take on this recipe sounds fabulous 🙂
Alejandra Loyet
So delicious. I made this with a cauliflower mash and it paired so well.
Lauren
Could I use lime wedges instead of lemon? Is regular chili powder the same as red chili powder?
Neha Mathur
Yes sure, you can.
Melissa
Love it! The i didn’t have butter so I subbed extra virgin olive oil. The sauce was delicious. I had a little sample before pouring it over the tilapia and it could be used as a tangy salad dressing with a kick! Simple and delicious. Thank you!
Tricia
if your making it from frozen should I defrost first. Is overnight okay to defrost
Neha Mathur
You can defrost it overnight in refrigerator or on counter for a few hours.
Charles Bodnar
I just thawed out 2 Tilapia fillets and will follow your receipe exactly. Will let you know how it comes out. My wife is not a big fish fan so we will see what happens. Thank you CB
Natalie
I subbed the butter for coconut oil (since I didn’t have any butter) and it turned out super delicious!
Tamra
I just made this recipe and it was a hit. I added shrimp to mine and was enough with fish for 3 to 4 people. Next time I am going to add cherry tomatoes like the lady above. will make again.
Christa P
Perfect except for the sliced lemons… The sliced lemons give too strong of a flavor. The little bit of lemon juice in the recipe is good enough. I love the spice from the chili powder to combat the tangy lemon. And who doesnt love garlic ????. I baked on 450 for 8 mins.
Neha Mathur
You can skip adding it next time.
LPhillips
Great recipe! Kept the Tilapia from getting too dry. We’re thinking it’s a keeper. 👍🏻

Butter Butter 🙂 But honestly it tastes great with both, so feel free to use whatever you fancy.

I know this is a simple recipe but I have to say it was simply delicious! Easy, fast and I had everything in the house to make it. I used the chili powder instead of paprika as it says ok to substitute. I served it with steamed broccoli and rice. Poured that delicious juice from the pan over the rice. I will be making this recipe again.👍
Carolyn
This was delicious and easy to prepare. Even easier to eat!! Thank you!
Brenda Martin
The flavor of this recipe is delicious. I used smoked paparika instead of hot.

Santana
Tonight was my 1st time ever making fish. I used this recipe and I’m soooooo glad that I did.
It was delicious and super easy.
I will definitely be making this again.
Thanks!
ForeverMama
Very tasty fish indeed and used smoked paprika that wasn’t hot but compensated with a bit of red chilies. The paprika really made it stand out. Thanks so much for sharing your lovely recipe, Neha!
Janice
Hi! I made this recipe, but I didn’t have any paprika so I used chili lime and it turned out really good. We aren’t real spicy people and it gave it just enough kick to be yummy. Thanks for the easy to follow instructions!!!
Lynette aka breezermom
I love fish, lemon and garlic…..and have been known to make things a little too spicy for most people. So this recipe was a winner for me. I did use amberjack instead of tilapia because it just looked better at the fish market. But they taste very similar, amberjack has just a bit whiter flake and has larger filets than tilapia. Delicious!
Sheila
Perfection! I don’t have to search any further, this is my go-to recipe for tilapia!
