Learn how to make Smoked Red Snapper on ANY grill or smoker!
Smoked Red Snapper Fillets are incredibly easy to prepare, whether you are using a pellet grill like a Traeger, Camp Chef, or Pit Boss, an electric smoker like a Masterbuilt, or just a conventional propane grill like a Weber.
Let’s go!
Seasoning your Red Snapper for Smoking
Red snapper holds up well to stronger flavors compared to more delicate fillets like tilapia and halibut.
You can go still gentle and delicate with a simple blend of salt, lemon pepper, thyme and garlic if that’s your thing.
You can brine or use an italian dressing marinade like we do on our smoked catfish fillets for 4-6 hours, or even overnight, to get even more depth of flavor before seasoning.
Our current favorite seasoning for smoked red snapper is Old Bay Blackening Seasoning.
It gives a nice kick in addition to the classic old bay flavors we love on seafood.
- A great mix of OLD BAY and authentic blackened flavors
- All Purpose seasoning perfect for seafood like shrimp, tuna or salmon; chicken and add Cajun flavor to everything you cook and eat.
Best Wood Choices for Smoked Red Snapper
Because we are only smoking the red snapper fillets for such a short period of time, you can really get away with any kind of smoking wood of your choosing.
If you want to keep it simple and straightforward, choose a lighter smoking wood. For smoked red snapper we especially like alder, oak, apple, or peach.
Want more smokey wood flavor? Go ahead and mix in some hickory or cherry.
- Contains most popular flavors- Apple, Mesquite, Hickory, and Cherry
- Works with electric and gas grills
Best Times and Temperatures for Smoked Red Snapper
What is the Best Temperature to Smoke Red Snapper?
We are going to set up the smoker for indirect cooking today a little higher than usual at 350°F.
When we are smoking fish, (unless we are looking to smoke small thin strips for preservation, like jerky where we dry out the protein on purpose at super low temps), long low and slow temps tend to dry out the fish before it cooks completely.
Fish also absorbs smoke much quicker than other proteins like pork and beef, so we don’t want it sitting on the moker for hours and hours.
Because we are setting the temperature higher, know that smoking over 300°F may burn any sugar in your traditional BBQ rub.
So for anything you are smoking above 300°F, stick to no sugar homemade blends or store bought no sugar rubs like Old Bay and another sugarless favorite of ours, Bad Byron’s Butt Rub.
Target Internal Temperature for Smoked Red Snapper
You HAVE to use a good instant read meat thermometer to know where the internal temperature is of your smoked red snapper fillets, especially because they will cook relatively FAST!
We are particular fans of this one from Thermopro because of its durability and affordable price.
We are targeting a final internal temperature of 145°F on the smoked red snapper to know that it is finished cooking.
How Long Does it Take to Smoke Red Snapper?
Some oilier fishes like our Maple Smoked Mackerel will take a couple hours to cook low and slow at 250°F
However, at 350°F, the typical red snapper fillet will only take about 30-40 minutes to cook and come up to 145°F internally.
This gives it enough of time to absorb a good amount of smoke and really develop some great flavors on the smoker, without taking up your whole day to cook.
But watch your internal temperature closely, smaller fillets may take less than 30 minutes to finish cooking!
Smoking Red Snapper with Cedar Planks, Grill Baskets, or Phat Mats
Option 1: Cedar Planks
You can experiment with smoking your red snapper on cedar planks for some added woods-ey flavor.
Check out our complete guide on how to grill with cedar planks HERE.
Make sure to soak the cedar planks in water for at least an hour before putting them on your grill or smoker so that they don’t char and burn.
This also helps release steam and flavor the red snapper fillets while they are smoking.
- Easy to use on gas & charcoal grills; large size
- Adds sweet-smoky flavor to your grilling favorites
- Great for beef, chicken, fish, pig, seafood or vegetables
Option 2: Use a Grill Basket or Grill Mat
Because red snapper fillets, and really any fish, are more delicate than other cuts of meat, you may be more successful if you place the fillets in a grill basket rather than directly on the grill grates of your grill or smoker.
We are particular fans of the ORDORA Portable Grill Basket because it comes with its own handle, making it much easier to manage and move lots of delicate food, even shrimp, scallops, and asparagus around with one quick motion.
Another option is to use a grill mat, which are becoming increasingly popular in many BBQ circles, especially for delicate veggies and small seafood like oysters.
Our personal favorite is the PhatMat Non Stick Grill Mat.
Just throw it down on your grill to keep your smoked red snapper (or any other food) from falling through.
It keeps your grates really clean, and when you are done, you just throw it right in the dishwasher!
- 🔥 GRILL LIKE A BOSS - Our heavy duty mesh design allows your barbeque masterpiece to fully absorb those awesome smoky flavors.
- 🔥 NO MESS - Never grill on a nasty grill grate again! These bbq mats for grill keeps all your barbecue creations from falling through the grates! Nonstick, easy clean up, reusable, washable and dishwasher safe!
Setting up your Smoker for Red Snapper
Vertical or Offset Charcoal Smoker
Fill your firebox or lower charcoal basin with a few handfuls of unlit charcoal and create a small hollowed out depression in the center where you can add your lit briquets.
If your smoker comes with a water pan, like the Weber Smokey Mountain, fill the water pan as well to help stabilize the temperature and add moisture to the cooking chamber.
Light a charcoal chimney about 1/4 way with charcoal and wait about 15 minutes for it to fully ignite.
You will not need too many briquets here because, like our Lemon-pepper Smoked Mahi Mahi, we are only smoking the red snapper for about 30-40 minutes at the most.
Fill your water pan first, then add the lit briquets to the center depression you created.
Keep the dampers about 1/2 way to 3/4 open until the cooking chamber temperature reaches about 325°F. Then slowly close them down until they are just barely open and you are maintaining a temperature of 350° F.
Place 1 chunk of your chosen smoking wood on top of your lit charcoal once the smoker is up to temperature and put your oiled and seasoned red snapper fillets on once the smoker is actively producing smoke.

Propane or Electric Smoker
Propane and electric options are some of the easiest smokers for beginners to start with.
Debating whether to buy a propane or electric smoker? Check out our COMPLETE Comparison Guide HERE.
For Propane: Open your gas valve and light the bottom burner. Adjust it to keep the temperature constant at 350° F.
Need a refresher? Check our our Complete Guide to How to Use a Propane Smoker HERE.
For Electric: Plug your electric smoker in, open the vents, and turn the temperature to 350° F.
While it comes up to temperature, add smoking wood chips, not pellets, to the smoking wood tray.
Fill the water tray if there is one.
Place your oiled and seasoned red snapper fillets either directly on the rack, or on your soaked cedar planks, in a grill basket, or on a Phat Mat, and close the door.
You will need to refill the wood chips every 30 minutes or so as they smolder out in the chip loader, whihc may only be one time, or not all if your red snapper fillets are very small.
Refilling wood chips is one of the major drawbacks, besides tray size, of electric smokers compared to pellet grills like Traegers and Pit Bosses.
However, we recently found a great solution.
If you are tired of having to reload fresh wood chips into our electric smoker, especially on longer cooks like pork butt and brisket, then check out this Masterbuilt Automatic Slow Smoker Attachment.
It basically burns new fresh wood chips at a constant rate, much like how a pellet grill works, freeing you up to do other things while getting your food nice and smokey!
- Continuous smoke when cold smoking or hot smoking up to 275˚F
- Ideal for smoking cheese, fish, bacon, and jerky
- Automatically heats wood chips with the push of a button
- Continuous wood feed system provides up to 6 hours of continuous smoke without reloading
Pellet Grill
Pellet grills like the ones from Traeger and Camp Chef are great for smoking red snapper.
Fill the pellet hopper with your choice of smoking wood pellets.
Plug in the pellet grill, turn it on and let it run through its start up process.
Then turn the temperature to 350°F.
When the pellet grill has come up to temperature, place your oiled and seasoned red snapper fillets in the pellet grill set up for indirect heat.
Never used a pellet grill like a Traeger or a Pit Boss before?

Gas or Charcoal Grill
On a gas or charcoal grill you will likely need to use a smoker box filled with wood chips, or a pellet tube smoker filled with wood pellets.
Think you need a fancy smoker to smoke food at home?
Think again. Great smoked food can be made right on your current gas or charcoal grill!
Check out this Step by Step Guide to Smoking on a Gas Grill HERE.
If you are unfamiliar with these gas grill smoking devices mentioned above, no worries, we have you covered!
You can read all about smoker boxes here, and see a selection of our favorite pellet tube smokers here.
Not sure which is best to use?
Check out this guide comparing smoker boxes to pellet smoker tubes.
In the case of smoked red snapper fillets, we would opt for just using the smoker box filled with some wood chips since we will be cooking for probably no longer than 45 minutes
Set up your gas or charcoal grill for indirect cooking with the burners or a small amount of lit briquets on one side and plan for your red snapper to be on the other side.
Once the temperature of your grill is around 350°F, place your smoker box or pellet tube smoker over the coals or lit burners and once smoke begins coming out, place your red snapper fillets on the opposite side of the heat.
Make sure to oil the grates on the indirect side well so that the smoked fish does not stick.
Monitor your Grill Temperature
Almost every grill and smoker will have some sort of temperature gauge on them.
Now, if you are using a pellet grill or electric smoker, you should be able to pretty accurately dial in your desired temperature of 350°F with the turn of a dial.
This is what makes them so convenient!
If, however, you are using a charcoal or propane grill/smoker, you can’t rely on the cheap lid mounted temperature gauge that come installed on them.
We have found these can sometimes be up to 30°F off from what the true actual temperature at the grill grate level.
This is unacceptable.
This is why you will always see competition cooks, and backyard chefs who know their stuff, using wireless digital probe thermometers to keep track of both their meat AND their cooking chamber.
And even if you have a fancy pellet grill like a Traeger or even an electric smoker, it can’t hurt to double check how accurate your temperature settings are to the true temperatures you are getting.
We are big fans of the ThermoPro Wireless Digital Meat Thermometer series.
- 300ft remote range and hassle-free setup: Wireless meat thermometer monitors your food and grill temp up to 300 feet away
- Dual probes for food and BBQ: Meat thermometer oven safe with highly accurate stainless steel food probe
- Food and ambient temp alarm: Set your desired food temp and HI/LOW temp range for your grill or smoker to know when to add more fuel
Best Ways to Serve Smoked Red Snapper
Your smoked red snapper fillets should be served immediately after removing them from the grill or smoker.
You can squeeze some lemon and serve over pasta or with some smoked vegetables, or just eat them as is!

Ingredients
- 2 lbs Red Snapper Fillets rinsed, patted dry, cut into (4) 8 oz portions

- ½ Lemon to squeeze over when finished (optional)
Cajun Blackening Rub
- 2 Tbsp Smoked Paprika
- 1 Tbsp Kosher Salt more or less to taste
- 1 Tbsp Onion Powder
- 1 tsp Garlic Powder
- 1 tsp Black Pepper
- 1 tsp cayenne powder (optional for heat)
- ½ tsp Dried Basil
- ½ tsp Dried Oregano
- ½ tsp Dried Thyme
Instructions
Prepare and Season the Red Snapper
- Divide the red snapper fillets into 8 oz portions. Rinse well and pat dry.
- Place the red snapper fillets on a cutting board and drizzle the olive oil over both sides of each fillet and rub to cover the surfaces.
- Combine the Cajun Blackening Rub ingredients in a small mixing bowl and then sprinkle over each side of the red snapper fillets.
- Place the fillets in a ziploc bag in the refrigerator while you prepare and preheat your grill or smoker.
Set up the Grill, Pellet Grill, or Smoker
- Light or turn on your smoker or pellet grill and set up the temperature to 350°F. If using a grill, set up the burners or charcoal on only one side for indirect cooking.
- Brush the grill grates with oil to keep the smoked red snapper from sticking or use an oiled grill basket to hold the fillets.
- Add your wood chunk(s) directly to the firebox or on top of the charcoal of a smoker, or use chips in a smoker box, or pellets in a tube smoker on a gas grill.
Smoke the Red Snapper
- Once smoke is being produced, put your red snapper filets in the smoker, or on the grill AWAY from the direct heat.
- Cook the red snapper fillets continuously at 350°F, flipping and rotating as needed, until they reach an internal temperature of 145°F. This should take about 30-40 minutes depending on the size of your fillets.
- Remove the smoked red snapper from the grill or smoker, optionally squeeze some lemon juice over the fillets, and serve immediately while hot.
I love blackened snapper but had never tried smoking it before. I did a little hotter than you say (because we we hungry haha) but still was good.
