  • 2 tbsp 2 tbsp Dijon mustard
  • 2 tbsp 2 tbsp finely chopped fresh parsley

  1. Season the fish with salt and pepper. Fry in butter for a couple of minutes on both sides.
  2. Boil the broccoli in a pot with lightly-salted water until fork-tender. Drain. Keep warm.
  3. Melt the butter for the sauce in a saucepan over medium heat. Add the remaining ingredients and let simmer for a couple of minutes.

    Yet another fabulous diet doctor recipe! I love this site. I used Annie's horseradish mustard instead of the dijon and grated fresh horseradish.
  2. Carol
    My cowboy sauce did not come together. It still tasted really good! I whisked and whisked, but it would not get creamy like a sauce. I wonder what I did wrong?
  3. Duncan
    Had the same issue as Carol. Followed exactly but the sauce absolutely refused to come together. Looked nothing like the photo .....

    To get the sauce to come together like that, I had the idea to start with a hollandaise sauce base. So i began with a room temperature egg yolk (not in recipe) and the 1Tbl. vinegar (from the recipe) in a metal bowl set on top a pot of simmering water, and whisked the butter in, gradually in small cubes. Once all the butter was all whisked in, I added the other ingredients (already prepped) gradually (except the horseradish which I wasn't in the mood for!) with the whisk. It turned out beautiful and was delicious on both my salmon and asparagus. The sauce left in the pan did break while we were eating dinner, so I would start with 2 egg yolks next time. But we gobbled it up anyway! Kids weren't impressed, but it meant more for us :)

    Dear DD,
    The recipes for cowboy sauce are different.
    The cowboy sauce with salmon has the Dijon sauce and vinegar but thefowboy sauce (on its own) doesn’t. Was that deliberate?

    (It’s incredibly delicious w the Dijon and vinegar).

    The thyme amount was a little overpowering, but otherwise the dish came out great.

    My sauce split but it came back together when I added a little more water and whisked again. I whisked with a fork in the end as the oil was splashing everywhere. It was so delicious with the salmon and broccoli and really satisfying. Thanks Diet Doctor!

    Ok this was delicious and filling. To overcome the sauce separating, I used my stick blender and whizzed it into an emulsion which held together beautifully. Whisking did nothing!

    I had the same problem with the sauce not coming together. I've tried whisking, stick blender, begging. Nothing worked. My wife however decided to add heavy whipping cream. That did the trick.
  10. Karen
    The trick that worked for me is very low heat on the butter. Don’t let it bubble or brown. Great recipe!

    My sauce didn’t come together well. My butter burned while cooking the fish. But I still liked the taste it just didn’t look pretty.
