6 Tbsp butter
1 pound of top sirloin or tenderloin, cut thin into 1-inch wide by 2 1/2-inch long strips
1/3 cup chopped shallots (can substitute onions)
1/2 pound cremini mushrooms, sliced
Salt to taste
Pepper to taste
1/8 teaspoon nutmeg
1/2 teaspoon of dry tarragon or 2 teaspoons of chopped fresh tarragon (optional)
1 cup of sour cream at room temperature
Melt 3 Tbsp of butter in a large skillet on medium heat. Increase the heat to high/med-high and add the strips of beef. You want to cook the beef quickly, browning on each side, so the temp needs to be high enough to brown the beef, but not so high as to burn the butter. You may need to work in batches. While cooking the beef, sprinkle with some salt and pepper. When both sides are browned, remove the beef to a bowl and set aside.
In the same pan, reduce the heat to medium and add the shallots. Cook the shallots for a minute or two, allowing them to soak up any meat drippings. Remove the shallots to the same bowl as the meat and set aside.
In the same pan, melt another 3 Tbsp of butter. Increase heat to medium high and add the mushrooms. Cook, stirring occasionally for about 4 minutes.
Remove mushrooms and reduce heat to low. Add the sour cream and stir in the beef and shallots, and mix throughly. Don't let the mixture simmer or boil or the sour cream will curdle
Serve over egg noodles (I used whole wheat).
Make 2 servings.
