Begin by Heating the Pan: Place a deep, sturdy pan on the stove and warm it over medium-high heat, adding a drizzle of olive oil.
Cook the Beef: Add the ground beef to the pan. Use your spoon to break it apart, ensuring it cooks into small, even pieces.
Add Onions and Garlic: Introduce diced onions and minced garlic to the pan with the beef. Continue cooking until the onions become soft and take on a golden-brown hue.
Incorporate Mushrooms: Now, stir in the sliced mushrooms, and continue to sauté the mixture for an additional 5 minutes.
Thicken with Flour: Sprinkle flour over the mixture, stirring well to ensure it's evenly distributed and smooth out any clumps that form.
Pour in Liquids and Seasonings: Gradually add in the beef broth and whipping cream, followed by a tablespoon of Worcestershire sauce, and season with half a teaspoon each of salt and black pepper. Stir and let the mixture come to a gentle simmer.
Simmer to Merge Flavors: Reduce the stove's heat to a lower setting and allow the concoction to simmer softly for around 5 minutes.
Final Touch of Sour Cream: Take the pan off the heat and blend in the sour cream, mixing thoroughly to ensure a consistent sauce. Taste and adjust the seasoning as desired.
Ready to Serve: Your Ground Beef Stroganoff is now ready to be served. Spoon it over a bed of cooked noodles, rice, or potatoes and enjoy this hearty and flavorful meal.
