Step 1

Make the spinach stuffing. Place the cream cheese, feta, and mozzarella into a medium mixing bowl. Roughly chop the baby spinach and add it to the cheese. Massage the spinach and cheese with your hands, until well combined (it should look like thick paste).

Step 2

Prep the salmon. Using a sharp knife, cut a pocket in the center of each salmon fillet.

Step 3

Season the salmon. Generously season the salmon fillets with the Cajun seasoning and brush them with olive oil on both sides.

Step 4

Stuff the salmon. Divide the spinach stuffing into four equal parts and spoon it into the salmon pockets.

Step 5

Bake the salmon. Bake the stuffed fillets in a preheated oven at 400ºF for 15-20 minutes, depending on how large your fillets are.
