Step 1

Gather all of your ingredients to make your oven-baked walleye.

Step 2

Pre-heat the oven to 350° Fahrenheit.

Step 3

Using a standard baking sheet, cut a piece of foil that is double the size of the sheet pan.

Step 4

Cover the sheet pan with ½ of the foil so that the shiny side is down, and the dull side of the foil is up. The idea of this is to be able to fold the other ½ of the foil over the fish and seal to cook.

Step 5

Spread the olive oil on the sheet pan foil.

Step 6

Sprinkle some of the seasoned salt and pepper onto the oiled foil.

Step 7

Lay the walleye fillets in a single layer on top of the seasoned oil, making sure that you are doing this on the sheet pan.

Step 8

Lightly season the fish fillets one last time.

Step 9

Slice the onion into thin rings, separate the rings and place onto the top of the walleye fillets.

Step 10

Fold the foil over so that you are completely covering fish. Roll the foil ends together starting with the opposite side of the folded foil. Then roll both the end sides to completely sealing the fish into the foil pouch.

Step 11

With a sharp knife, gently poke a few holes into the top of the foil pouch. Make sure to not puncture the bottom of the foil.

Step 12

How Long to Bake Walleye?Place the sheet pan into the pre-heated oven and bake for 30 to 45 minutes.

Step 13

Check the oven baked walleye fish after 30 minutes to see if the fish is done. To do this, use a fork to try and flake the thickest part of the fish. You want the fish to flake easily and be white in color. If you see any translucent color or if the fillets do not want to flake apart easily, then put back into the oven and cook for 10 – 15 minutes longer.
