I make steak oscar frequently. We always have leftovers of steaks we have grilled. I have been using Knorrs bernaise mix for years. I was a finatic about making it from scratch till a friend introduced me to Knorrs. However, to cut down on calories and fat in the bernaise, I use non-fat milk, no butter, and a couple tablespoons (to your taste) of dried tarragon. It's really, really good and almost guilt free. I use shrimp, lobster or crab meat.....whatever I happen to have in the freezer and usually alway have blanced asparagus frozen. I serve it with long grain and wild rice and a nice light pear salad. It's one of our favorite meals and really sooo very easy, especially with the steak being already grilled.
I served this one night along with the Keg's mushrooms neptune and it was a great hit with my husband. The only thing I did different was I used rib eyes and added a few scallops to go with the crab meat!
Awsome!! Made this last summer and will be making it again!!
