Eileen's Tips for Success
- You can use parchment paper in your baking dish instead of greasing it for easy cleanup.
- I like to leave the lemon wedges in the baking dish while the fish cooks for even more flavor.
- I like to serve these cajun tilapia fillets over a bed of rice.
- The size of your fillets will affect your cooking times, so make sure to use a meat thermometer to check them for doneness.
- If using frozen fish, be sure to defrost the fish in the refrigerator before proceeding with the recipe.
