Ingredients
Method
- Place sliced beef in a bowl. Toss with flour and salt until lightly coated.
- Heat a large skillet over medium heat. Melt butter. Add beef in a single layer and cook undisturbed for 2 to 3 minutes until browned. Turn and cook another 2 minutes. Transfer beef to a plate.
- In the same skillet, add chopped onion and sliced mushrooms. Cook for about 5 minutes until softened and lightly golden.
- Return beef and juices to the skillet. Stir in garlic powder, cream of mushroom soup, water, and tomato paste. Mix until smooth and simmer gently for 5 to 6 minutes until thickened.
- Remove skillet from heat. Slowly stir in sour cream until fully combined and creamy.
- Serve immediately over warm cooked egg noodles.
Notes
For deeper flavor, deglaze the skillet with a splash of beef broth after browning the meat and scrape up any browned bits before adding the soup.
To prevent curdling, temper the sour cream by mixing it with a few spoonfuls of hot sauce before stirring it into the pan off the heat.
You can substitute ground beef for a budget-friendly option. Brown and drain excess fat before adding the sauce ingredients.
