Beef Stroganoff

Step by stepInstructions

1. Pat the beef dry and season with salt and pepper.
2. Heat the butter and oil in a large skillet over high heat and sear the beef in batches until browned; transfer to a plate.
3. Reduce the heat to medium, add the onion and mushrooms, and cook until golden and their liquid evaporates, about 8 minutes.
4. Sprinkle with flour, stir for 1 minute, then whisk in the broth and mustard and simmer until slightly thickened, about 5 minutes.
5. Return the beef and any juices to the pan, stir in the sour cream, and heat gently without boiling for 3-4 minutes.
6. Season to taste, scatter with dill, and serve over noodles or kasha.
