An easy casserole version of a classic, this Beef Stroganoff Casserole is a meal the whole family is sure to enjoy!


  • 8 ounces wide egg noodles
  • 2 tablespoons olive oil
  • 1 small onion, chopped
  • 3 cloves garlic, minced
  • 1 (8 ounce) package sliced fresh mushrooms
  • 1 pound sirloin steak, cut into strips
  • 2 teaspoons salt, divided
  • 2 teaspoons ground pepper, divided
  • 2 tablespoons worcestershire sauce
  • 1 cup beef broth
  • 3/4 cup all-purpose flour
  • 1 cup milk
  • 1 cup sour cream
  • 1 cup crispy fried onions


  1. Preheat oven to 350°F. Lightly grease a 9×13-inch baking dish and set aside. Cook egg noodles according to package directions and keep warm while you prepare the meat sauce. I used beef broth to boil my noodles for a little added flavor.
  2. In a large skillet, heat the olive oil over medium-high heat and then add the onion, garlic and mushrooms. Saute for 8-10 minutes or until mushrooms are tender. Add the steak and sprinkle with 1 teaspoon salt and 1 teaspoon pepper. Continue to cook until beef is completely browned. Stir in worcestershire sauce and beef broth. Let simmer over low heat while you prepare the thickening ingredients.
  3. In a medium bowl, whisk together the flour, 1 teaspoon salt and 1 teaspoon pepper. Whisk in milk until well combined. Stir flour mixture into meat mixture. Add sour cream and stir until completely combined.
  4. Transfer cooked noodles to the bottom of the prepared baking dish. Top with creamy beef mixture. Sprinkle with crispy fried onions.
  5. Bake in the middle rack of the oven for 30 minutes. Let cool a few minutes before serving.
