This is the third time I have made this dish and my husband and I love it. I am sure I will bake it again and again.

Delish who knew! I think the baking time can come down a little. I didn't have provolone I used mozz swiss and parm. YUM.
This was a hit with my kinda picky husband and stepdaughter! Followed the recipe with exception of the provolone as I didn't have any on hand. I subbed more mozzarella for the provolone. I used red fish and sea trout as that is what we had in the freezer from a prior fishing trip. Excellent! Smells divine while cooking - wait til the top of the cheese starts to brown before you take it out of the oven. Will make again!!
Oh my yum!!! This was amazing! I didn't change anything- I literally couldn't wait to eat this! I cook for one but I'm glad I made two servings! Definitely will make this again!
Just made it. Substituted the catfish for tilapia. Family loved it.
Delicious as my family are not fish lovers. I did the recipe the same but added garlic dill and seasoned pepper.
I think this is my new favourite 'go to' recipe for fish. Made this a few nights ago and absolutely loved how it turned out. I did have to make a change - the only cheese I had on hand was parmesan and cheddar but the cheddar substituted very well for the provolone and mozzarella - and the cod I had didn't have any skin. One other slight alteration: I sprinkled a tiny bit of smoked paprika on the fish before adding the rest of the ingredients. Oh The end result was one tasty meal VERY easy to make. Thanks so much for sharing this recipe!
Yes I made it. I used tilapia instead and had everything else in frig was very easy. Mom husband really enjoyed it.
I didn't have the provolone cheese so I made it without. It was delicious and can't wait to make it again.
