Ingredients Equipment Method Notes

Ingredients
  

  • 1.5 lb beef sirloin or chuck, thinly sliced against the grain
  • 8 oz egg noodles, uncooked
  • 8 oz cremini or button mushrooms, sliced
  • 1 medium yellow onion, finely diced (about 1 cup)
  • 3 cloves garlic, minced
  • 2 cups beef broth, low sodium preferred
  • 1 cup sour cream
  • 4 oz cream cheese, softened
  • 2 tbsp Worcestershire sauce
  • 2 tbsp all-purpose flour
  • 2 tbsp olive oil
  • 1 tsp dried thyme
  • 1 cup shredded mozzarella cheese
  • 2 tbsp fresh parsley, chopped (for garnish)
  • salt and black pepper to taste

Equipment

  • Large skillet
  • pot (for noodles)
  • 9x13-inch casserole dish
  • Mixing bowls
  • Whisk and spatula

Method
 

  1. Preheat the oven to 350°F (175°C) and grease a 9×13-inch casserole dish.
  2. Boil the egg noodles for 2 minutes less than package directions, drain, and set aside.
  3. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Season beef with salt and pepper and cook in batches for 2–3 minutes until browned. Transfer to a plate.
  4. Add remaining oil to the skillet. Cook mushrooms undisturbed for 2–3 minutes until browned. Add onions and cook 3–4 minutes until soft, then stir in garlic and cook 30 seconds.
  5. Sprinkle flour over the vegetables and stir for 1 minute. Gradually whisk in beef broth, scraping up browned bits. Add Worcestershire sauce and thyme, then simmer 3–5 minutes until thickened.
  6. Remove skillet from heat, cool slightly, then stir in sour cream and cream cheese until smooth. Return beef and juices to the skillet and season with salt and pepper.
  7. Combine noodles with beef mixture and transfer to casserole dish. Top with mozzarella cheese.
  8. Cover with foil and bake 20 minutes. Remove foil and bake another 10–15 minutes until bubbly and golden.
  9. Let rest 5–10 minutes before serving. Garnish with fresh parsley and enjoy warm.

Notes

Slice beef thinly for the best texture. Double the batch for freezing or large gatherings. Serve with a fresh green salad or steamed veggies for a balanced meal.
