I use a recipe from Betty Crocker that is fabulous. Much better than just using beef and sour cream.
I use Cambell's beef consomme, undiluted. The flavor is a bit "je ne sais quoi" than beef broth. Probably saltier. I use two cans to get plenty of sauce. I use sirloin tip, and I keep packages of it cut up in my freezer so I can make Mongolian beef or beef Stoganoff whenever I want. It is more tender than stew meat, and doesn't take as long to cook. My technique is a bit different from the recipe in the book, too. Hmm, sounds good for dinner tonight.
1 1/2 lbs beef, cut into slices
2 T butter
2 cans Cambell's beef consomme, undiluted
1/3 cup red wine if available
2 T catsup
1 clove minced garlic
1 medium onion
8 oz mushrooms, sliced (optional)
6 heaping Tablespoons flour
1/2 cup sour cream (don't use fat free)
noodles of choice
Melt better in large, deep skillet. Add onions and garlic, saute until wilted. Add mushrooms (if using), saute until tender. Add beef and saute until meat is cooked. Reserve 2/3 cup of the consomme, stir the remaining consomme, wine and catsup into the skillet. Heat to boiling, cover and simmer for about 10 minutes, or until the noodles are ready.
Shake the reserved consomme and the flour in a tightly covered containter. Stir the flour mixture slowly into the meat mixture. Heat to bubbling, stirring constantly for about 1 minute. It should thicken very nicely. Reduce heat to low, and add about 1/2 cup sour cream (if you like more, you can use more, but I find more than this amount is overwhelming). Serve beef over hot noodles.
Better Homes and Gardens has a Beef Stroganoff recipe that is more involved and doesn't sound as good. I think it may be more bland.
When I was in college, the dining hall served Beef Stroganoff. It was mystery meat mixed with sour cream. Yuck. What a let down after eating the above recipe for 15 years.
