How to Make Grilled Walleye with Blackened Seasoning
Preheat your grill to medium heat.
In a small bowl, combine the paprika, smoked paprika, garlic powder, onion powder, cayenne pepper, thyme, oregano, black pepper, and kosher salt.

Pat the walleye fillets dry with paper towels and lightly brush both sides with olive oil. Coat the fillets evenly with the blackened seasoning.
Place the seasoned walleye on a large sheet of heavy-duty aluminum foil. Add a few small pats of butter over the top of each fillet, then loosely fold up the edges of the foil to create a shallow packet while leaving the top slightly open so some of the smoky grill flavor can still circulate.

Place the foil on the grill and cook for 10 to 12 minutes, or until the fish flakes easily with a fork and reaches an internal temperature of 145 degrees F. Cooking time will vary depending on the thickness of the fillets.
Carefully remove the foil from the grill, squeeze fresh lemon juice over the fish, and serve immediately with Greek yogurt tartar sauce.

Pro Tips for Grilled Walleye

Storage
Store leftover grilled walleye in an airtight container in the refrigerator for up to 3 days.
To reheat, warm the fish gently in a skillet over low heat or in a 300 degree F oven until heated through. Avoid microwaving for too long, as the fish can dry out.
