My husband just loved this recipe, Nagako. He doesn't much care for onions, I only used one. I doubled the mushrooms, lemon juice & white wine. I also added 1 extra clove of garlic, a pinch each of parsley and rosemary and then 2 fresh snipped basil leaves at the end. I only thickened the sauce slightly, as we wanted enough to spread over rice. Served this with fresh steamed green beans, as well.

This was an "okay" dinner served over whole wheat couscous and some homemade tartar sauce. I *did* add about two tablespoons of butter to the final sauce to enrichen it with flavor - even so, I don't think I will keep it in rotation at our house.

This was very good...I used maui onions and it turned out better like onions though!

After cooking the fish with the sauce, you have to make and cook another newer and fresher sauce that you can pour on the fish so that the sauce will not be dark and overdone. The fish will taste better.

Oh my this was super tasty and fast. I did make some changes after reading other reviews. I doubled the liquid, (wine and lemon juice), used an 8 oz. pkg. of baby bella mushrooms, chopped in half for a deeper flavor and more texture, added a little butter to the olive oil, and probably 6-8 garlic cloves. Also threw in a good quarter cup of fresh chopped basil leaves, and finished with a fresh chopped tomato just before serving. This is a quality, healthy dish with deep flavor. By doubling the liquid, the cornstarch thickening was minimal - just enough to keep it from being watery. Served it over whole wheat cous cous cooked in salt free broth, and garden fresh green beans. The little leftovers from lunch today were even better. A real keeper.

This recipe is fantastic! I have also used it with Talapia. I'm always looking for fish recipes that my kids will like, and all four plus my husband loved this!

We loved this. I didn't have any mushrooms on hand, but it was still great and I used regular chardonnay, it was excellent!
