- 1 cup beef broth

Instructions for Beef Tetrazzini Casserole
1. Cook the Egg Noodles
- Bring a large pot of salted water to a boil. Add the 12 ounces of egg noodles and cook according to the package directions until al dente. Drain and set aside.
2. Cook the Beef
- In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Add the thinly sliced beef sirloin and cook for 4-5 minutes, until browned. Season with salt and pepper to taste. Remove the beef from the skillet and set aside.
3. Sauté the Vegetables
- In the same skillet, add the 2 tablespoons of butter. Once melted, add the chopped onion, minced garlic, and sliced mushrooms. Cook for about 5-6 minutes, until the onions are soft and the mushrooms are tender.
4. Make the Sauce
- Sprinkle the ¼ cup all-purpose flour over the sautéed vegetables and stir to combine, cooking for about 1-2 minutes to remove the raw flour taste.
- Gradually add the 1 cup beef broth and 1 cup heavy cream, stirring constantly to create a smooth sauce. Bring the mixture to a simmer and cook for 3-4 minutes, until it thickens slightly.
- Stir in the ½ cup sour cream, 1 cup grated Parmesan cheese, and ½ cup grated mozzarella cheese, stirring until the cheese is fully melted and the sauce is creamy. Season with salt and pepper to taste.
5. Combine and Assemble
- Preheat your oven to 350°F (175°C).
- In a large bowl, combine the cooked egg noodles, beef, and creamy mushroom sauce. Toss everything together until evenly coated.
- Transfer the mixture into a greased 9×13-inch baking dish.
6. Bake the Casserole
- Bake the casserole in the preheated oven for 20-25 minutes, or until bubbly and golden on top.
7. Garnish and Serve
- Once the casserole is baked, remove it from the oven and sprinkle with freshly chopped parsley for garnish.
- Serve hot and enjoy!
