1-First, prepare all ingredients by dicing the onion, slicing the mushrooms, and mincing the garlic cloves to make cooking straightforward. This step helps streamline the process and ensures everything is ready when you need it.

2-Next, in a large skillet, heat 1 tablespoon of olive oil over medium heat.

3-Then, add the diced onion and sliced mushrooms, sautéing them until softened, which takes about 5 minutes. This builds a flavorful base for your ground beef stroganoff.

4-Once that’s done, stir in the minced garlic and cook for another minute to release its aroma.

5-Now, increase the heat to medium-high and add the 1 pound of lean ground beef. Break it apart as it cooks until it’s browned and no longer pink, about 7-8 minutes, and season with salt and pepper.

6-Sprinkle in the 2 tablespoons of flour and stir well, cooking for 2 minutes to remove any raw taste.

7-Gradually pour in the 1 cup of beef broth while stirring to avoid lumps, then add the 1 cup of heavy whipping cream. Bring it to a simmer and cook until the sauce thickens, around 5 minutes.

8-Finally, reduce the heat to low, stir in the 1/3 cup of sour cream and 1 tablespoon of Worcestershire sauce until everything is creamy and smooth.
