When I need a quick but satisfying dinner, this is the recipe I make. Thinly sliced steak and mushrooms in a creamy, savory sour cream sauce, all on the table in under 30 minutes.
Heat 2 tablespoons of oil in a large deep pan over medium-high heat. Brown the beef in batches for 1 minute on each side until lightly browned. Remove to a plate.
Add the remaining 2 tablespoons of oil to the pan. Cook the onions, garlic, and mushrooms for 8-10 minutes until softened, and most of the moisture is evaporated.
Stir in the flour until evenly distributed in the mushroom mixture.
Add the beef broth, Worcestershire sauce, and Dijon mustard. Scrape up any browned bits from the bottom of the pan. Simmer for 1-2 minutes until slightly thickened. Remove from the heat.
Pour the sour cream into a separate bowl. Slowly whisk a few tablespoons of the hot beef broth into the sour cream, then stir it back into the pan (this prevents the sour cream from curdling).
Return the beef and any juices to the pan. Taste and season with salt and black pepper. Serve immediately over egg noodles!
Notes
Steaks to use: In addition to ribeye, top sirloin and striploin are good options. Cut them thinly against the grain to ensure they're tender.
