Instructions
- Preheat oven to 350°F (175°C) and grease a 9×13-inch baking dish.

- Add mushrooms and cook for 5 minutes until browned and moisture is released.
- Sprinkle in flour and stir for 1 minute. Gradually add beef broth, stirring to thicken.
- Reduce heat and stir in heavy cream, sour cream, and half the Parmesan. Season with salt and pepper.
- Return beef to the skillet and simmer for 2–3 minutes.

Notes
- Substitute sirloin with thinly sliced flank steak or ground beef for convenience.
- Add extra vegetables like peas, spinach, or bell peppers for added nutrition.
- Use half-and-half instead of heavy cream for a lighter version.
- The casserole can be assembled ahead and baked later.
- Let it rest for 5 minutes before serving for easier slicing.
