📝 Instructions

10 steps

1. In a large skillet, heat the butter and olive oil over medium heat until the butter melts.

2. Add the diced onion and cook for 3-4 minutes, stirring frequently, until softened.

3. Add the minced garlic and sliced mushrooms. Cook for 5-6 minutes until the mushrooms are tender and have released their moisture.

4. Sprinkle the flour over the vegetables in the skillet and stir to coat. Cook for 1-2 minutes to remove the raw flour taste.

5. Gradually pour in the beef broth while stirring constantly to create a smooth sauce. Bring the mixture to a gentle simmer and cook for 3-4 minutes, allowing it to thicken slightly.

6. Stir in the sour cream, Dijon mustard, and paprika. Mix until the sauce is smooth and creamy.

7. Add the thinly sliced leftover roast beef to the skillet. Stir to coat the beef in the sauce and heat through for 2-3 minutes. Avoid overcooking to keep the beef tender.

8. Season the stroganoff with salt and black pepper to taste.

9. Serve the stroganoff over cooked egg noodles. Garnish with freshly chopped parsley if desired.

10. Enjoy your comforting and delicious Leftover Roast Beef Stroganoff!
