Ingredients & Their Purpose

For the Beef and Pasta Base:

• 1 lb beef sirloin or chuck steak, thinly sliced
  Adds a meaty, hearty base with rich flavor and satisfying texture.
• 1 lb spaghetti or linguine
  Acts as the perfect vehicle to carry the sauce; its long strands soak up the creaminess.
• 2 tablespoons olive oil
  Used to sauté the beef, helping it sear properly and develop flavor.

For the Creamy Mushroom Sauce:

• 2 tablespoons unsalted butter
  Creates a rich foundation for the sauce.
• 1 small onion, finely chopped
  Adds sweetness and depth to the sauce.
• 3 cloves garlic, minced
  Boosts the flavor profile with an aromatic punch.
• 8 oz mushrooms, sliced (cremini or white button)
  Brings an earthy note and adds texture to the sauce.
• 2 tablespoons all-purpose flour
  Thickens the sauce to coat the pasta evenly.
• 2 cups whole milk
  Adds creaminess and binds the sauce.
• 1 cup heavy cream
  Enhances richness and provides a velvety mouthfeel.
• ½ cup beef broth
  Infuses the sauce with extra umami and intensifies the beef flavor.
• 1 teaspoon Worcestershire sauce
  Gives depth and a subtle tangy-sweet finish.
• 1 teaspoon salt, or to taste
  Enhances all the individual flavors.
• ½ teaspoon black pepper
  Adds mild heat and balances the creaminess.
• ¼ teaspoon ground nutmeg (optional)
  Provides subtle warmth that complements creamy sauces.

For the Topping:

• 1½ cups shredded mozzarella cheese
  Melts beautifully for a gooey, cheesy top layer.
• ½ cup grated Parmesan cheese
  Adds salty sharpness and helps form a golden crust.
• ¼ cup breadcrumbs (optional)
  Adds crunch and a contrast to the creamy interior.

Step-by-Step Instructions

Step 1: Cook the Pasta

1. Bring a large pot of salted water to a boil.
2. Cook the spaghetti until al dente, about 1-2 minutes less than the package instructions.
3. Drain and toss with a splash of olive oil to prevent sticking. Set aside.

Step 2: Brown the Beef

1. Heat olive oil in a large skillet over medium-high heat.
2. Add the sliced beef in batches to avoid crowding the pan.
3. Sear until browned and just cooked through, about 3-4 minutes per batch.
4. Remove and set aside.

Step 3: Sauté the Vegetables

1. In the same skillet, melt butter.
2. Add onion and sauté until translucent, about 3 minutes.
3. Add garlic and mushrooms; cook until mushrooms are browned and tender, about 5 minutes.

Step 4: Make the Sauce

1. Sprinkle flour over the vegetables and stir to coat evenly.
2. Cook for 1-2 minutes to eliminate the raw flour taste.
3. Slowly whisk in milk, cream, and beef broth.
4. Stir in Worcestershire sauce, salt, pepper, and nutmeg (if using).
5. Simmer for 5-7 minutes until thickened to a creamy consistency.

Step 5: Combine and Assemble

1. Preheat oven to 375°F (190°C).
2. In a large mixing bowl, combine the cooked spaghetti, beef, and cream sauce. Mix thoroughly.
3. Transfer the mixture into a greased 9×13-inch baking dish.
4. Sprinkle the top evenly with mozzarella, Parmesan, and breadcrumbs (if using).

Step 6: Bake

1. Bake uncovered for 25-30 minutes, or until the top is golden and the casserole is bubbling.
2. Let rest for 10 minutes before serving for cleaner slices and better flavor development.
