How to grill catfish on a propane grill

Grilling catfish on a propane grill can be a delicious and simple way to prepare this fish. Here's a step-by-step guide on how to grill catfish by Papa Ken at Maine Grilling Products.


  • Catfish fillets
  • Olive oil or cooking spray
  • Seasonings (such as salt, pepper, paprika, garlic powder, or your favorite fish seasoning)
  • Lemon wedges (optional, for serving)



  1. Preheat the Grill:

    • Start by preheating your propane grill to medium-high heat, typically around 350 to 400 degrees Fahrenheit (175 to 200 degrees Celsius).
  2. Clean and Oil the Grill Grates:

    • Use a grill brush to clean the grill grates and remove any residue from previous cooking sessions.
    • Dip a folded paper towel in a small amount of oil (vegetable oil or olive oil) using tongs. Carefully rub the oiled paper towel on the grill grates to create a non-stick surface. This will help prevent the catfish from sticking to the grill.
  3. Season the Catfish:

    • Brush or spray both sides of the catfish fillets with olive oil or cooking spray to prevent them from sticking to the grill.
    • Season the catfish fillets with your choice of seasonings. You can keep it simple with salt and pepper, or use a combination of your favorite seasonings. Some people enjoy adding a little paprika, garlic powder, or lemon zest for extra flavor.
  4. Grill the Catfish:

    • If you are using a smoker box this is the time to add your favorite wood chips.  Place the seasoned catfish fillets directly on the preheated grill grates.
    • Close the grill lid and cook the catfish for about 4-6 minutes per side, depending on the thickness of the fillets. Catfish is done when it flakes easily with a fork and has a golden-brown grill marks. Be careful not to overcook, as catfish can become dry if cooked for too long.
  5. Optional Grill Mats (for delicate fillets):

    • If you're concerned about the catfish sticking to the grill or if the fillets are very delicate, you can use a grill mat.
    • Place the seasoned catfish fillets on the grill mat.  This will make it easier to handle and prevent sticking.
  6. Serve:

    • Once the catfish is cooked to your desired level of doneness, carefully remove it from the grill using tongs.
    • Serve the grilled catfish hot with lemon wedges for a burst of freshness, if desired.

Grilled catfish is a tasty and healthy dish that pairs well with a variety of sides, such as rice, vegetables, or a fresh salad. Enjoy your meal!  Papa Ken
