Lemon Pepper Grilled Catfish
Whether you have some fresh-caught catfish waiting in the freezer, or you’re looking to branch out and try something new, this lemon pepper grilled catfish recipe is a perfect place to start.
Can You Grill Catfish?
Catfish is an excellent fish to cook on the grill. It’s a sweet and rather mild fish that absorbs other flavors easily. Keep in mind farmed catfish tastes much milder than wild-caught catfish. Wild catfish can be fishy and even a bit muddy.
With this in mind, this recipe rubs the fish in a flavorful lemon pepper mayo and cooks the catfish on a cedar plank to infuse it with all the good BBQ flavors possible. This recipe can be cooked on any grill you have available, including a gas grill or pellet grill. I quite like the flavor added by cooking on a charcoal grill.
This grill catfish recipe is a great recipe to try if you’ve never tried catfish before. The flavors are fresh and traditional, so you can rest assured that your entire family will at least TRY dinner.
This lemon pepper catfish is a classic in terms of flavor, but grilling it on a cedar plank adds a smoky element that turns it up a major notch. It’s a great way to cook up some fish from a recent fishing trip or to try out something new.
How to Grill Catfish
It doesn’t get much easier than this grilled catfish. This catfish cooks in less than 30 minutes, and if you’re in a rush, you can quickly soak the planks and get right to it! Dinner will be ready before you know it.
- Soak. Fully submerge the cedar planks in water and soak for at least 45 minutes (or up to 2 hours) prior to cooking. For some added fun, add a few cups of wine, stock, or liquor to the water.
- Season. Make the mayonnaise-based paste (ingredients in the printable recipe card below) in a small bowl. Use the backside of a spoon to evenly spread the rub over both sides of the catfish.
- Grill. With your favorite grill preheated to 400 degrees F, place the planks directly on the grill grates, close the lid, and cook for 15-20 minutes.
- Serve. Once the fish is fully cooked, remove it from the grill and top with parsley and parmesan cheese (the cheese is optional, but it really finishes this fish). Serve immediately and enjoy your gorgeous grilled catfish.
How Long to Grill Catfish
This catfish takes around 15-20 minutes to fully cook with the grill preheated and running steady at 400 degrees F.
When cooking fish (or any cut of meat for that matter), I prefer to monitor my meal by temperature instead of time. This way, I can ensure that the meat is cooked to the perfect doneness every time. Catfish is safe when cooked to 145 degrees F using a reliable thermometer. As you are nearing the 15-minute mark, take the temperature of your fish and remove it once the temp reaches 145 degrees F.
Notes for Grilling Catfish
Before you jump into the recipe below, I have a few important notes you shouldn’t forget when making this catfish.
- Soak the cedar planks. Soak the planks for at least 45 minutes before grilling. Right before placing the fish on the planks, cook on the grill for just a minute to dry the surface.
- Skip the skin. Skinless catfish works best for this recipe as the filet can absorb some of the flavors from the cedar planks while it cooks on the grill.
- Save some lemon wedges for serving. Fresh lemon is the perfect complement to the smoky catfish, and a fresh squeeze of lemon finishes this recipe off perfectly.
