Instructions
Step 1: Prepare the Beef - Trim excess fat from the steak and slice into thin strips against the grain. Sprinkle with salt and set aside.
Step 2: Sauté the Vegetables - Heat olive oil in a large skillet over medium heat. Add chopped onion and cook until translucent (3-5 minutes). Add minced garlic and sliced mushrooms, sauté until mushrooms are browned (5-7 minutes).

Step 5: Finish the Dish - Remove from heat, stir in sour cream and Dijon mustard. Season with salt and pepper to taste. Adjust consistency with more beef broth if needed.
Step 6: Serve - Serve over cooked egg noodles or rice, garnish with fresh parsley.
Notes
For the best flavor, choose a well-marbled cut of beef. Slice the beef thinly against the grain for tenderness. Adjust sauce thickness to your liking.
