Creamy Beef Stroganoff with Mushrooms: Restaurant Flavor in Your Kitchen!

Heat oil or butter in a large skillet over medium-high heat. Add the sliced beef and cook until browned on all sides. Remove beef from the pan and set aside.

In the same pan, add onions and sauté until translucent. Add mushrooms and cook until softened and lightly browned.

Sprinkle the flour over the mushrooms and onions, stirring constantly to avoid lumps. Cook for about 1 minute.

Slowly pour in the beef broth while stirring to create a smooth sauce. Bring to a simmer and let it thicken.

Return the cooked beef to the pan. Stir in the mustard and sour cream, mixing well to combine. Heat gently, but do not boil, to prevent sour cream from curdling.

Season with salt and pepper to taste. Cook for another 2–3 minutes until everything is heated through.
