Cooking Steps
- In a large skillet, melt butter over medium-high heat, then sear the beef strips in batches until browned and set aside.
- Add chopped onion to the skillet and sauté until softened, then add sliced mushrooms and cook until tender.
- Stir in flour and cook for one minute, then gradually whisk in beef broth and bring to a simmer.
- Reduce heat to low, return beef to the skillet, and stir in sour cream and Dijon mustard.
- Season with salt and pepper to taste, then simmer gently for 10-15 minutes, or until the sauce thickens and flavors meld.
Notes
For best results, do not overcrowd the pan when searing the beef; sear in batches if necessary. Serve over egg noodles or rice.
