Beef Stroganoff

Ingredients

For the beef:

• 1 1/2 pounds beef sirloin or tenderloin (cut into thin strips)
• 2 tablespoons vegetable oil
• Salt and black pepper (to taste)

For the sauce:

• 1 tablespoon unsalted butter
• 1 medium onion (finely chopped)
• 3 cloves garlic (minced)
• 8 ounces cremini or button mushrooms (sliced)
• 1 tablespoon all-purpose flour
• 1 cup beef broth
• 1 cup sour cream
• 1 tablespoon Dijon mustard
• 1 tablespoon Worcestershire sauce
• 1/4 cup chopped fresh parsley (for garnish)

For serving:

• 8 ounces egg noodles or rice (cooked according to package instructions)

Instructions

1. Prepare the Beef:

   1. Season the beef strips with salt and black pepper.
   2. Heat the vegetable oil in a large skillet or sauté pan over medium-high heat.
   3. Add the beef strips in batches to avoid overcrowding. Sear the beef until browned on all sides, about 2-3 minutes per side. Remove the beef from the skillet and set aside.

2. Make the Sauce:

   1. In the same skillet, add the unsalted butter. Once melted, add the chopped onion and cook until softened and translucent, about 3-4 minutes.
   2. Add the minced garlic and sliced mushrooms. Cook until the mushrooms are browned and any liquid has evaporated, about 5-7 minutes.
   3. Sprinkle the flour over the mushrooms and onions. Stir well to combine and cook for 1-2 minutes to eliminate the raw flour taste.
   4. Gradually add the beef broth while stirring to avoid lumps. Bring the mixture to a simmer and cook until slightly thickened, about 3-4 minutes.

3. Finish the Dish:

   1. Reduce the heat to low and stir in the sour cream, Dijon mustard, and Worcestershire sauce. Mix until smooth and well combined.
   2. Return the browned beef strips to the skillet, along with any accumulated juices. Simmer for 5-7 minutes, or until the beef is cooked through and the sauce is creamy and well incorporated. Adjust seasoning with additional salt and pepper if needed.

4. Serve:

   1. Serve the beef stroganoff over cooked egg noodles or rice.
   2. Garnish with freshly chopped parsley and additional sour cream if desired.
