Recipe Information
Ingredients
- 2 cups leftover roast beef
- 3 cups egg noodles (uncooked)
- 2 tablespoons butter
- 1 small onion (diced)
- 2 cloves garlic (minced)
- 2 tablespoons all-purpose flour
- 1.5 cups beef broth
- 1 cup sour cream
- 2 cups frozen mixed vegetables (thawed)
- 1.5 cups shredded cheddar cheese
- 0.5 teaspoons salt
- 0.25 teaspoons black pepper
- 0.5 cups breadcrumbs
- 1 tablespoon olive oil
Instructions
Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish and set it aside.
Cook the egg noodles according to package instructions until al dente. Drain and set aside.
In a large skillet, melt the butter over medium heat. Add the diced onion and cook for 3-4 minutes, or until softened. Add the garlic and cook for 1 additional minute.
Sprinkle the flour over the cooked onion and garlic. Stir well and cook for 1-2 minutes to make a roux.
Gradually whisk in the beef broth, stirring constantly to avoid lumps. Cook for 2-3 minutes until the mixture thickens.
Lower the heat and stir in the sour cream, salt, and black pepper. Mix well until smooth.
Add the chopped leftover roast beef, thawed mixed vegetables, and cooked egg noodles to the skillet. Toss everything until evenly coated in the creamy sauce.
Pour the mixture into the prepared casserole dish and spread it out evenly. Sprinkle the shredded cheddar cheese over the top.
In a small bowl, combine the breadcrumbs and olive oil. Stir to coat the breadcrumbs, then sprinkle them evenly over the cheese layer.
Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and the top is golden brown.
Remove from the oven and let the casserole cool for 5 minutes before serving.
Serve warm and enjoy this comforting meal with a side salad or crusty bread, if desired.
