I absolutely loved this, but the picky hubby strikes again . He complained about the sour cream, so I guess my only option is to ditch the recipe. I did the plain meat hamburgers, and used about 2T fresh parsley instead of the dried. I did question how much butter to use - finally settled on 3T, enough to cover the bottom of my skillet, melted.

The mushroom sauce is ADDICTIVE! I have been trying to find a copycat version of a mushroom burger at our local restaurant (White Spot); this turned to be completely different - It's far better! The sour cream made the difference (instead of say, just cream). I added about 1tbsp of black pepper and a hint of worstershire. My home-made patties are a little fancier, but I think plain hamburger patties would have worked even better - the mushroom sauce should be the centre of attention. Anyhow, great recipe, thank you!

Oh my - these were soo good and easy. I used reduced fat sour cream and canned mushrooms because it was all I had and it tasted just great. My DH loved it as well. I will definitely be adding this one to my rotation of recipes - thanks for a great recipe!
