“Why This Casserole is a Must-Try for Cheese and Mushroom Lovers”

  • Loaded with mushrooms, ground beef, and Swiss cheese, this casserole is packed with flavor and texture.
  • Creamy and comforting, it’s the ultimate comfort food for chilly evenings or lazy weekends.
  • The addition of Italian seasoning and Worcestershire sauce gives it an extra depth of flavor that’ll keep you coming back for more.
  • This casserole is incredibly versatile and can be easily adapted to your taste. Swap out the ground beef for turkey or chicken, or use different types of mushrooms to mix things up.

  • 1 (16 oz) package of potato dumplings or gnocchi (454g)
  • 8 oz baby portobello mushrooms, sliced (227g)

  3. Stir in minced garlic and cook for 1-2 minutes, or until fragrant, then season with Italian seasoning.
  4. Add ground beef and cook until browned, then drain fat, if necessary, and mix in Worcestershire sauce, cream of mushroom soup, and heavy whipping cream.
  5. Reduce heat to medium and continue cooking for another 3-5 minutes, giving flavors a chance to blend, then stir in potato dumplings and cook for another 5 minutes. (Note: if not enough space in skillet, combine in 9×13 and mix together.)
