1/2cupwhite wineif avoiding wine, replace with more broth
1 1/2cupsbeef broth
1 TbspWorcestershire sauce
3Tbspflour
1/2cupsour cream
Instructions
Start by heating 2 tablespoons of butter in a large skillet over medium-high heat. Season the beef with salt and pepper, then add it to the pan. Sear the beef on all sides until browned, about 4–5 minutes. Once done, remove the beef from the pan and set aside.
In the same skillet, add the remaining 2 tablespoons of butter. Toss in the onions and garlic, sautéing them for about 3–4 minutes until they become soft and fragrant. Then, add the mushrooms and cook for another 5 minutes, stirring occasionally until they’ve softened and released their moisture.
Pour the white wine into the skillet and scrape the bottom of the pan to release all the flavorful brown bits. Let the wine simmer for a few minutes until it reduces by half.
Sprinkle the flour over the onions, mushrooms, and garlic, stirring constantly for about 1–2 minutes. Slowly whisk in the beef broth and Worcestershire sauce, making sure there are no lumps. Bring the mixture to a simmer and let it cook for 5 minutes to thicken slightly.
Once the sauce has thickened, reduce the heat to low and stir in the sour cream. Continue to cook until the sauce is smooth and creamy.
Return the beef (along with any juices) to the skillet, stirring everything together. Let the stroganoff simmer for a few minutes until the beef is heated through and the flavors have melded.
