I bought some fresh perch for the first time and came to cooks.com to see what I could make with it. I just made this dish for dinner and we all loved it!!! (my 13 year old daughter, my husband and myself) I followed the recipe ingredients exactly using olive oil to saute the onions and light mayonaise for the sauce. We will have this again! Very easy, and would be good to make for company as well. I served it with a salad and steamed broccolli and cauliflower. Enjoy!!!!

Wonderful recipe. I chose olive oil over butter or generic cooking oil. Suggestion: Add capers, as much as you like. I used semi-thawed frozen perch, so there was a lot of liquid -- serve with rice (I used basmati.) Oh, I love perch.
