Preparation Steps

• In a large skillet, heat vegetable oil over medium-high heat. Add ground beef and cook until browned, breaking it up with a spoon. Drain off any excess grease.
• Add chopped onion and sliced mushrooms to the skillet. Cook until softened and lightly browned, about 5-7 minutes.
• Stir in minced garlic, salt, and pepper. Cook for 1 minute more until fragrant.
• Sprinkle flour over the beef mixture and stir to combine. Cook for 1-2 minutes.
• Gradually whisk in beef broth and Worcestershire sauce. Bring to a simmer and cook, stirring occasionally, until the sauce has thickened, about 5-7 minutes.
• Remove the skillet from the heat. Stir in the sour cream until well combined and creamy. Do not boil after adding sour cream.
• Serve hot over egg noodles or rice. Garnish with fresh parsley if desired.
