Ingredients

• 1 Tbsp olive oil
  
• 1 lb lean ground beef
  
• 1/2 medium onion, diced
  
• 1 lb mushrooms, sliced
  
• 2 garlic cloves, minced
  
• 2 Tbsp all-purpose flour
  
• 1 cup beef broth
  
• 1 cup heavy whipping cream
  
• 1/3 cup sour cream
  
• 1 Tbsp Worcestershire sauce
  
• 1/2 tsp salt, adjust to taste
  
• 1/2 tsp ground black pepper, adjust to taste

Instructions

1. Heat a heavy, deep pan over medium-high and add the olive oil. Add the ground beef and cook while breaking it into small pieces. Mix in the diced onion and minced garlic, cooking until the onion softens and turns golden.
2. Stir in the sliced mushrooms and continue cooking for about 5 minutes, or until they become tender. If the mushrooms release excess liquid, allow it to cook off.
3. Sprinkle the flour over the mixture and stir until it is fully blended in, breaking up any lumps as needed.
4. Pour in the beef broth, heavy whipping cream, Worcestershire sauce, salt, and black pepper. Bring the mixture to a gentle simmer, then lower the heat and let it cook for about 5 minutes.
5. Take the pan off the heat and stir in the sour cream. Adjust seasoning if desired. Serve over noodles, rice, or potatoes.
