Instructions

  1. Combine the beef broth and dried porcini in a small saucepan.
  2. Bring to a boil, remove from heat, cover, and let steep for 30 minutes.
  3. With a slotted spoon, lift the porcini out of the broth, chop coarsely and set aside.
  4. Strain the broth through a sieve and set aside.
  5. Heat 1 tbsp of the oil and the butter in a large skillet (not a non-stick) over medium high heat.
  6. When the oil is hot, add the cremini mushrooms and saute, stirring often until they are browned, 5- 6 minutes.
  7. Transfer to a bowl.
  8. Season the beef strips generously with kosher salt and pepper and dredge in the flour.
  9. Add 2 tbsp oil to the pan and heat over medium-high heat.
  10. When oil is hot, add the beef, spreading it in a single layer.
  11. After about a minute, turn each piece to brown the other side.
  12. Don't overcook!
  13. Work quickly, the whole process only takes a couple of minutes.
  14. Remove beef to the same bowl with the cremini.
  15. (Work in smaller batches, if you prefer).
  16. Melt the remaining 3 tbsp butter in the pan over medium-high heat.
  17. Add the onion.
  18. Saute, scraping up the browned meat bits at the bottom of the pan.
  19. When the onions just start to brown (about 4- 5 min), pour in the reserved porcini soaking broth.
  20. Stir in the mustard, Worcestershire sauce, porcini, cremini and beef, along with any accumulated juices.
  21. Bring to a simmer while stirring.
  22. Cook just until the sauce thickens slightly, 1- 2 minutes.

  24. Taste, and adjust seasonings.
  25. Serve over cooked noodles, sprinkled with parsley.
