Ingredients and Preparation
- Heat oil in a large skillet over medium heat. Add the beef and sauté for 3-4 minutes, until browned on all sides. Remove from skillet and set aside.
- Add onion to the skillet and sauté for 3-4 minutes, until translucent. Add the mushrooms and cook for another minute, until soft.
- Add the beef back to the skillet, and mix in the salt, pepper, tomato paste, and water. Cover and cook over low heat for about 4 minutes. Mix in crème fraiche and cook for another minute. (If using sour cream, mix in at the very end—do not continue to cook.)
- Drizzle with lemon juice and then sprinkle with parsley.
