Questions & Replies

  1. This looks fantastic but can it be made in advance and cook later?


  1. This was absolutely DELICIOUS!! I didn't expect it to be so tasty and the fish just melted in our mouths. Brilliant. Will most absolutely be making this often!!!
  2. I have been using this recipe for a number of years and I added French fried onion rings to the mix and on top 5 minutes before the casserole was done. Delicious!
  3. Did not make any changes. It was perfect.
  4. We really liked it. I didn't use onions. I sprinkled roasted garlic powder on the fish before I poured the sour cream mixture over it. Will make this again.
  5. 5 stars due to the surprisingly yummy taste for such little effort and few ingredients. The only change I made was using lime juice instead of lemon. And I had a frozen fish fillet that had been in my freezer WAY to long... if this recipe could made that not just palatable but super tasty, it's a keeper for me!


  1. This was very good and easy to make. I substituted lime juice for the lemon juice.
