Ingredients
  

  • Ingredients:
  • 1 ½ pounds beef sirloin or tenderloin thinly sliced into strips
  • Salt and pepper to taste
  • 2 tablespoons all-purpose flour optional, for dredging
  • 3 tablespoons butter divided
  • 1 tablespoon olive oil
  • 1 medium onion finely chopped
  • 3 cloves garlic minced
  • 10 ounces cremini or button mushrooms sliced
  • 1 cup beef broth
  • 1 tablespoon Dijon mustard
  • 1 tablespoon Worcestershire sauce
  • ¾ cup sour cream full-fat preferred
  • 1 tablespoon fresh parsley chopped (for garnish)
  • Egg noodles rice, or mashed potatoes, for serving

Instructions
 

  • Instructions:
  • Prep the Beef:
  • Lightly season the beef strips with salt and pepper. If desired, toss them in a little flour to help the sauce thicken later.
  • Sear the Beef:
  • In a large skillet over medium-high heat, melt 1 tablespoon of butter with the olive oil.
  • Add the beef in a single layer (do it in batches if needed) and sear quickly on both sides until just browned.
  • Remove the beef from the skillet and set aside.
  • Cook the Vegetables:
  • In the same skillet, add the remaining 2 tablespoons of butter.
  • Add the onions and sauté for about 3 minutes until softened.
  • Stir in the garlic and cook for another 30 seconds until fragrant.
  • Add the sliced mushrooms and cook for 5–7 minutes, stirring occasionally, until they are browned and their moisture has evaporated.
  • Make the Sauce:
  • Pour in the beef broth, scraping up any brown bits from the bottom of the pan (this adds a ton of flavor!).
  • Stir in the Dijon mustard and Worcestershire sauce.
  • Let the sauce simmer for about 5 minutes to reduce slightly.
  • Finish the Dish:
  • Reduce the heat to low. Stir in the sour cream gently, making sure the sauce does not boil (to prevent the sour cream from curdling).
  • Return the seared beef and any juices back into the skillet.
  • Simmer for another 2–3 minutes, just until everything is warmed through and the beef is tender.
  • Serve:
  • Spoon the Beef Stroganoff over cooked egg noodles, rice, or mashed potatoes.
  • Sprinkle with fresh parsley for a burst of color and flavor.
