    Smoked Halibut with Garlic BBQ Marinade

    Jump to Recipe Print Recipe

    Learn how to make smoked halibut on ANY grill or smoker!

    Halibut is a deliciously flaky, delicate, whitefish that tastes GREAT when smoked.

    It's also incredibly easy to prepare and to smoke, 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.

    Seasoning the Halibut

    Halibut  is like a blank canvas when it comes to seasoning.

    You can go gentle and delicate with a simple salt, pepper, garlic, marinade lie in our recipe below.

    Mix the spices with some olive oil in a ziploc bag and let it marinate for about an hour while you get your smoker set up.  You can also add in some smoked paprika for color and depth of flavor.

    Alternatively, you can go a little bigger and use a spicier BBQ rub like our current favorite Three Little Pigs Kansas City BBQ Rub.

    Best Wood Choices

    Because we are only smoking the halibut fillets for such a short period of time, you can really get away with any kind of smoking wood of your choosing.

    pellets in a bucket

    If you want to keep it simple and straightforward, choose a lighter smoking wood like oak, apple, or peach.

    Middle of the road?  We really like hickory or cherry for smoking halibut.

    And if you want a full in your face mesquite flavor, well, use mesquite.  But prepared for it to possibly overpower a lot of the tilapia flavor.

    But if you want a more delicate flavor, then go lighter with some conventional wood choices.

    Remember that pellet grills only take wood pellets. Do not try feeding wood chips into a pellet grill.

    Electric smokers take wood chips, as do smoker boxes.

    If you are smoking on a charcoal grill or using a firebox on a pellet grill or gas grill, you will go for wood chunks.

    You can also experiment with cooking your halibut on cedar planks for some added wood flavor.

    Check out our complete guide on how to grill with cedar planks HERE.

    Best Temperature for Smoking Halibut

    We are going to set up the smoker for indirect cooking at 250-275°F.

    trager pellet grill set to 250 degrees

    Because halibut is so lean, anything lower tends to dry out the fish before it cooks completely.

    Anything higher and it cooks too fast to absorb any smoke flavor before its finished.

    Target Internal Temperature

    You HAVE to use a good instant read meat thermometer to know where the internal temperature is of your halibut filets, especially because they will cook relatively FAST!

    We are particular fans of this one from ThermoPro because of its durability and affordable price.

    Check Price on Amazon

    We are targeting a final internal temperature of 145°F on the halibut to know that it is finished cooking. 

    How Long Does it Take to Smoke Halibut?

    At 250°F, the typical halibut filet will take about 45-60 minutes to cook and come up to 145°F internally.

    This gives it plenty of time to absorb a good amount of smoke and really develop some great flavors on the smoker.

    Setting up your Smoker for Halibut

    Optional: Use a Grill Basket or Grill Mat

    Because halibut is more delicate than other cuts of meat, you may be more successful if you place the filets in a grill basket rather than directly on the grill grates.

    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 around with one quick motion.

    Another option is to use a grill mat, which are becoming increasingly popular in many BBQ circles.

    Our personal favorite is the Grillaholics Mesh Grill Mat.

    Just throw it down on your grill to keep your fish (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!

    Vertical or Offset Charcoal Smoker

    Read Char-Broil Reviews on Amazon

    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 ¼ way with charcoal and wait about 15 minutes for it to fully ignite.

    You will not need too many briquets here because we are only smoking the halibut for about an hour at the most.

    Fill your water pan first, then add the lit briquets to the center depression you created.

    Keep the dampers about ½ way to ¾ open until the cooking chamber temperature reaches about 225°F.  Then slowly close them down until they are just barely open and you are maintaining a temperature of 250° 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 halibut on once the smoker is actively producing smoke..

    Propane or Electric Smoker

    See Masterbuilt Reviews on Amazon

    Propane and electric options are some of the easiest smokers for beginners to start with.

    For Propane: Open your gas valve and light the bottom burner. Adjust it to keep the temperature constant at 250° 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 250° 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 halibut fillets on the rack and close the door.

    Pellet Grill

    Check out this Z Grills Pellet Grill on Amazon

    Pellet grills like the ones from Traeger and Camp Chef are great for smoking tilapia.

    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 250°F.

    When the pellet grill has come up to temperature, place your seasoned halibut directly on the grill grates or in a grill basket with the pellet grill set up for indirect heat.

    Never used a pellet grill like a Traeger or a Camp Chef before? 

    Read our ultimate guide to pellet grills to learn why they are so easy to use and how to set one up for success every time.

    Gas or Charcoal Grill

    Check out the Weber Spirit on Amazon

    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 our Ultimate 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!

    Read everything you need to know about smoker boxes here, and see a selection of our favorite pellet tube smokers here.

    In the case of halibut, we would opt for just using the smoker box filled with some wood chips since we will be cooking for no longer than 45-60 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 halibut to be on the other side.

    charcoal grill set up for indirect heat

    Once the temperature of your grill is around 250°F, place your smoker box or pellet tube smoker over the coals or lit burners and once smoke begins coming out, place your halibut on the opposite side of the heat.

    Make sure to oil the grates on the indirect side well so that the 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 250°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 of your smoker at the grill grate level is.

    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.

    ThermoPro TP08 300FT Wireless Meat Thermometer with Dual Probe

    If you're willing to invest in a really convenient thermometer, we recommend the MEATER wireless thermometer.

    It pairs with an app on your smart phone using Bluetooth to give you the internal temperature of your food, the ambient temperature of the cooking chamber, and even an estimated time when your food will finish cooking. We think of it as a GPS for food!

    Serving Suggestions

    Your smoked halibut fillets should be served immediately after removing them from the smoker.

    No need to rest or wait to eat!

    For drinks, a crisp white wine like chardonnay or riesling pairs nicely with the white fish if you kept the seasoning simple.

    If you went big and bold with a sweet and spicy BBQ rub like Three Little Pigs, you might do better pairing your halibut with a crisp beer like an American pale ale or a Belgian White Beer.
