Method
- Brown the Beef: Preheat a heavy, deep pan or Dutch oven over medium-high heat with the olive oil. Add the ground beef and stir, breaking it down into tiny pieces.1 Tbsp olive oil, 1 lb lean ground beef
- Aromatics: Add the diced onions and minced garlic to the beef. Saute the mixture until the onion is translucent and the beef is golden brown.1/2 medium onion, 2 cloves garlic
- Cook the Mushrooms: Add the sliced mushrooms to the skillet. Saute for about 5 minutes or until the mushrooms have softened. If the mushrooms release a lot of liquid, continue cooking until the juice evaporates.1 lb mushrooms
- Thicken the Sauce: Sprinkle the all-purpose flour over the meat and mushroom mixture. Stir constantly for about a minute to incorporate the flour and remove any lumps.2 Tbsp all-purpose flour
- Simmer: Pour in the beef broth, heavy whipping cream, Worcestershire sauce, salt, and black pepper. Bring the mixture to a gentle simmer. Turn the heat to low and let it simmer for about 5 minutes to allow the sauce to thicken and the flavors to meld.1 cup beef broth, 1 cup heavy whipping cream, 1 Tbsp Worcestershire sauce, 1/2 tsp salt, 1/2 tsp ground black pepper
- Final Touch: Remove the pan from the heat. While stirring constantly, slowly add in the sour cream. Stir until the sauce is smooth and creamy. Taste and adjust seasoning if necessary.1/3 cup sour cream
Notes
To prevent the sauce from curdling, always remove the pan from the heat before stirring in the sour cream. Using 90% lean ground beef is ideal as it prevents the sauce from becoming overly greasy.
