Notes

  • If the mushrooms and onions soak up too much of the moisture in the pan, add additional Worcestershire sauce 1 teaspoon at a time to avoid them drying out.
  • Do not replace the sweet yellow onion with white or red. A sweet yellow onion is the perfect onion for this dish - white or red onion will change the flavor completely.
  • I use white mushrooms in this recipe, but I also enjoy using shiitake mushrooms or baby Portobello mushrooms. Use whichever you prefer, just make sure they're sliced to relatively the same size!
