"I made this in the oven, and we loved it. I decided to try it in the Air Fryer, and the fish was equally good - dinner was ready a little faster and with fewer dishes to clean. Thanks for a great recipe!"
📋 TL;DR — Recipe Summary
- What: Tender, flaky baked blackened tilapia with a bold, spicy homemade seasoning made from common pantry spices.
- Why: A quick, easy fish dinner with minimal cleanup. No premade blackening seasoning needed.
- How: Brush fresh or thawed tilapia with oil, coat with seasoning, and bake in a hot oven until done.
🐟 Ingredients
- Tilapia fillets: Fresh or frozen and thawed.
- Olive oil: Or melted butter, to help the seasoning stick and keep the fish moist.
- Homemade blackening seasoning: Made with paprika, onion powder, garlic powder, thyme, oregano, cayenne pepper, salt, and black pepper. Adjust the cayenne to your preferred heat level.
- Cooking spray: A light spray helps prevent the seasoned surface from drying out while baking.
👨🍳 Quick Overview: Baked Blackened Tilapia in the Oven
1. Make the blackening seasoning, adjusting the cayenne pepper to your preferred heat level.
2. Pat the thawed tilapia dry, brush with oil, and coat both sides with the seasoning.
3. Place the fish on a prepared, oiled sheet pan and lightly spray with cooking spray.
4. Bake until nicely browned and flaky, reaching an internal temperature of 145°F for about 7–10 minutes, depending on thickness. Check early to avoid overcooking.
For more details, keep reading. See the recipe card below for complete instructions and to print.
🤔 Options, Variations, and Tips
- Cajun or Creole tilapia: Use your favorite Cajun or Creole seasoning instead of the homemade blackening rub.
- Adjust the heat: Increase or decrease the cayenne pepper to suit your taste. See the blackening seasoning section below for details.
- Frozen tilapia: Thaw overnight in the refrigerator for more predictable cooking. You can cook from frozen, but it takes longer. Always cook to 145°F.
- Prevent sticking: Use an oiled foil-lined baking sheet, parchment paper, or a silicone baking mat.
- Avoid overcooking: Tilapia dries out quickly. Check early with an instant-read thermometer.
🐟 Can I Substitute Other Fish for Tilapia?
Yes. Other mild white fish, such as cod, haddock, or halibut, work well with this blackening seasoning.
Cooking time will vary with the thickness of the fillets. Plan on about 10 minutes per inch of thickness, but always check for a final internal temperature of 145°F with an instant-read thermometer.
🔥 Blackening Seasoning—Adjusting the Heat
You can adjust the spiciness of homemade blackening seasoning with your choice of paprika and the amount of cayenne pepper.
Paprika: Regular sweet paprika is my preference. Smoked paprika adds a smoky flavor, while hot paprika adds extra heat.
Cayenne pepper: Adjust the amount to your taste. My approximate heat ratings for this recipe are:
- 1 teaspoon: Very hot (9/10)
- ½ teaspoon: Hot (7/10)
- ¼ teaspoon: Mild to moderately spicy (3–4/10)—my usual amount
- None: Little heat unless you use hot paprika.
🍽️ Serving Suggestions
Serve baked blackened tilapia with lemon or lime wedges and Homemade Tartar Sauce. Add a simple vegetable, rice, or potatoes for an easy dinner.
Fish tacos: This blackened tilapia makes terrific fish tacos. Serve in warm tortillas with guacamole and your favorite salsa. Mexican rice makes a great side.
Homemade Tartar Sauce
Quick and Easy Tartar Sauce uses only four ingredients you already have in your kitchen. A small homemade version that is better than the store-bought version.
🧊 Storage and Reheating
Blackened tilapia is best served fresh. Refrigerate leftovers in an airtight container for up to 3 days.
Reheat gently in the oven or microwave until hot. Avoid overcooking, which will dry out the fish.

Recipe Notes
Pro Tips
1. Extra seasoning: The blackening rub makes more than needed. Use only ¼ to ⅓ of the mixture per pound of fish. Store the unused seasoning in an airtight container.2. Adjust the heat: Start with ¼ teaspoon cayenne for moderately spicy fish. Use ½ teaspoon for hot or 1 teaspoon for very hot. Omit it for milder seasoning.
3. Other seasonings: Cajun or Creole seasoning may replace the homemade blackening rub.
4. Frozen tilapia: Thaw overnight in the refrigerator for the most predictable results. Cooking from frozen takes longer.
5. Other fish: Mild white fish, such as cod or haddock, can be substituted. Adjust cooking time for thickness.
6. Prevent dryness: A light spray of cooking oil over the seasoned fish helps keep the surface from drying out.
7. Nutrition: Nutritional information does not include the optional tartar sauce.

Katie Snuckums says
Thank you very much for this amazing recipe! As much as myself & my family enjoyed this unusual, but great recipe, I had trouble getting the top layer to form a crust. That was disappointing, but other than that, it was greatly flavorful!
Dan Mikesell AKA DrDan says
Hi Katie,
Welcome to the blog.
You won't get a crust so you can stop trying unless you want to modify the recipe. What you see in the pictures is just spices

Hello DrDan:
I am a baby boomer from Canadian Maritimes and I appreciate your publicity for my homeland. I have used your method for cooking fish many times since I discovered your recipe, and it gives wonderful results with tilapia and every other type of fish I've tried.
I have a favour to ask. I would like to get my millenial daughter hooked on your recipe to get her to eat more healthy but text and photos are not her style. Is there any chance of you adding a small video to your page for this recipe?

Ellie says
Thank you! Excellent!
I forgot about Pam, omitted cayenne (don't like it),halved dry ingredients, baked at 425 convection and was totally surprised how moist and tasty the pieces of tilapia turned out.
Who knew :-)
P.S. Beautiful pictures of your dog. My dog got baked tilapia too minus all the spices. He's still licking his chops lol. Thank you again :-)
Samantha Chase says
Love love!!! I added coriander, slap your momma, and magic shrimp seasoning. I also soaked my tilapia in butter for about 30 minutes before seasoning/cooking. Turned out AMAZING ( I always tweak recipes and I never really measure, just how I was taught ) but the base you have posted is wonderful, and I will be making this again. Btw kids loved it too. Also I added dill weed and Dijon mustard to the tarter sauce.
Laura says
Excellent recipe. Cooked on grill at 425.next time I'll leave it on a bit longer for the blackening effect, but the spices were perfect. We used the full amt of cayenne because we love spicy!!
Thank you!
Pat Dougherty says
Sounds great. I've tried cast iron on the stove, but the smoke alarm was not happy.
A couple of questions: Can I use un-oiled silicone baking pads instead of foil? If I'm doing a smaller quantity of fish, does the cooking time change?
Thanks!
DrDan says
Hi Pat,
Welcome to the blog.
So your questions. The silicon mat. Yes, but I think it needs a bit of oil. So a light spray of PAM in both sides of the fish would probably be better. But you can try without.
Cooking time would be unchanged for smaller quantities.

Krystal Alley says
Dr.Dan, will the recipe be messed up if I don't use the Cayenne pepper at all? My husband is allergic to it.
DrDan says
Hi Krystal,
Welcome to the blog.
There is a lot of tastes other than the cayenne so go ahead. Of course, there will be no heat.

Colleen says
Loved the recipe! I like seafood and I'm always looking for new fish recipes. Baking is way better than cooking on the stovetop. Less mess and more reliable (for me at least).
DrDan says
Hi Colleen,
Welcome to the blog.
I do love this recipe. The seasoning is just right. I have issues with stovetop fish, it is always fried, makes a mess and I always break the fish somehow. Plus I don't seem to get it done correctly. Baking or grill are much more reliable for me.
Thanks for the note.

Elizabeth G. says
Ohhh I'm excited to eat this blackened tilapia again tonight. It is VERY good! I've made your tartar sauce as well and it's just as good. My question is if I double the tartar sauce how long will it keep in the fridge?
DrDan says
I would only keep it for about 3 days just like most leftovers.
Thanks for the note.

Tammy says
I usually make our tilapia with fresh lemon and pepper, but didn't have any lemons. So I did a quick google search for recipes with Tilapia, and found yours. Very very good. Happy to not only stumble upon this recipie, but will notlw check out your others. Thanks!
Idriceanu says
Thank you ! Lots of great ideas, love it !!
Judy Uhl says
Made for dinner tonight and it smells delicious! Yummy. Used 1/4 tsp. Cayenne. Just right!
Donna says
I'm new to your cooking for 2 recipes (you had me at the oven baked Iowa pork tenderloin recipe a week or so ago! Will be trying that soon!). I haven't searched a lot, but this blackened tilapia recipe made me wonder if you had an oven baked blackened salmon recipe? I'm all about oven baking, too, as it's so much easier than standing over a stove and then cleaning up the grease spatters. Glad to have found a (former) Iowan providing recipes! (I'm nestled halfway between Cedar Rapids and Iowa City. Born and raised an Iowan... GO HAWKS! LOL!)
DrDan says
Hi Donna,
I do love the baked pork tenderloin. I always get disappointed anymore with the Iowa restaurant versions. They seemed better years ago. Also, I try to bake and not fry if I can. It probably helps that I use real tenderloin and HyVee "tenderloin" is really loin.
I don’t have much seafood on the blog. I'm from deep in farm country (Chariton) and if it didn’t moo, oink or cluck, you didn’t eat it. Having said that, I’m learning to love less “fishy” things like this recipe. About blackened salmon, no I have never done it but if you find “The 10-Minute Rule for Cooking Fish” which should help adapt this to salmon.
Nice to hear from somebody from Iowa. GO CYCLONES ;)
Kenneth says
Dr. Dan, I am not sure what to say other than excellent. I was looking for a fish recipe for fish tacos and found your blackened tilapia on a grill. However it was 1*F and my gill was covered in snow so I when noticed a link to the oven baked blackened tilapia I had to give it a try as my wife does not like me to blacken things on the stove top due to the mess and the smoke.
I had 1 lb of halibut fillets (3) just over an inch thick. I used your recipe as written with one change. I was out of cayenne powder so I sub'd 1 teas of NM chili powder. I cooked 6 minutes per side and it came out great. Cooked but still moist and flaky. We made fish tacos with flour tortillas, cole slaw, and your easy tarter sauce. My wife was suitably impressed. This is another recipe that goes in the "do it again" stack. Thanks from Alaska.
Teresa C says
Question: do I need to defrost the fish first?
DrDan says
Hi Teresa,
A general role is to double cooking time for frozen fish. I think that is a bit much for something this thin. I would thaw mainly since I don't think the seasoning would penetrate the fish well. Froze is usually vacuum packed so it won't take long in a pan of cool water.
