Can You Grill Frozen Fish?

Yes, you can grill frozen fish! Here's how we do it in Minnesota.

  1. We get a box of frozen fish fillets. These fillets are individually frozen so they are pretty easy to reach in and grab a couple of pieces for the grill.
  2. If there's any freezer ice on them, we rinse the fish off. The first time I did this, I placed them on a wooden cutting board and started to rinse them. What I wasn't expecting was as the fish were rinsed, they refroze to my cutting board, so then I had to run water across them, and loosen them from my cutting board with a knife.

The rest of the instructions are below.

2 fillets, feeds two


  • 2 frozen fish fillets
  • 2 tablespoons Old Bay seasoned salt
  • 2 tablespoons spray butter
  • 2 tablespoons olive oil


  1. Rinse ice crystals off fish. Spray them with butter. Place a thin layer of olive oil on a piece of aluminum foil, then sprinkle the foil with some Bay seasoned salt and place your fish fillets on top of the salt. Sprinkle the top of the fish with the seasoned salt, as well.
  2. Sprinkle some lemon juice across the fillets and grind some peppercorns across the top.
  3. Turn your grill to high heat and place your fish fillets on the foil, on the grill. Set your timer for 20 minutes, and keep the grill closed while you're cooking.
  4. When the moisture cooks out of the fish, keep cooking until the moisture around the fish has hardened into a crispy, dried mass. The fish is now done.

Frozen Is Just as Good as Fresh

We have tried to use the frozen fish in our air fryer with little success, and we have deep-fried the pieces with some success; but when I found out that I didn't have to thaw the pieces before I put them on the grill, I was elated but skeptical.

After I got them rinsed off and I put olive oil on the aluminum foil, I sprayed them with I can't Believe it's Not Butter and put a generous amount of Old Bay seasoning on them. I have a pepperball grinder and sprinkled freshly ground peppercorns across them and squirted lemon juice on them.
