Made with tender sirloin steak, fresh mushrooms, and a creamy sauce served over egg noodles. This classic dish is easy to make and tastes great when you start with fresh ingredients and add a few touches like white wine and sour cream for added flavor. This dish will not disappoint!
Slice steak and pat dry as needed. Season both sides with salt and pepper as much as desired.
Over medium-high heat, melt 2 tablespoon of the butter in a large skillet. Once butter is bubbling, add steak in a single layer in the pan. Sear for 2-3 minutes until browned before flipping over and searing the other side. Move steak to a plate once cooked.
Reduce heat to medium. Without cleaning the pan, add remaining butter and onions. Cook for 2-3 minutes or until the onion are lightly browned. Add sliced mushrooms and cook until the mushrooms are soft and browned. About 4 minutes. Stir as needed to cook evenly. Add white wine to the hot pan. Bring to a boil. Scrape all the brown bits into the liquid — this will add lots of flavor!
While mushrooms are cooking, whisk together the beef stock, Worcestershire sauce, flour, and garlic until well combined and not lumpy.Pour mixture into the pan and bring to boil. Stir until thicken, about 5 minutes.
Add cooked steak back to the pan along with the sour cream and stir until combined and completely heated through but not boiling.
Serve hot over a bed of warm, cooked egg noodles. Sprinkle with Italian parsley for garnish and enjoy immediately!
Notes
Depending on the size of your pan, you may have to cook the steak in batches. Thinly slice the onions so that they cook and soften quickly.
