What is "kidney pie"?

Kidney pie is a traditional British dish that is both hearty and flavorful. The pie features diced beef or lamb kidneys, which are cooked with a variety of vegetables, such as onions, carrots, and mushrooms, along with herbs and spices, such as thyme and bay leaves, to create a savory filling. The filling is then placed into a pastry crust and baked until the crust is golden brown and flaky on the outside, and the filling is tender and flavorful on the inside. The dish is often served with a rich and savory gravy, which adds even more depth of flavor to the already rich and hearty filling. Kidney pie is a classic comfort food that is often enjoyed during the colder months.
