A steak pie is a traditional British dish that combines steak with any number of other ingredients, such as potatoes, cheese, herbs and other meat or organs. Once the steak and other ingredients are cooked together to form a stew-like dish, pastry dough is used to cover and seal the ingredients for baking into a pie. There are premade pies on the market and whether you are reheating a homemade pie or heating frozen pie for the first time, adhering to a few heating techniques will help you turn out a ready-to-eat steak pie.
Preheat your oven to 175 degrees Celsius (350 degrees Fahrenheit). Use an oven to heat a steak pie rather than a microwave. A microwave will likely moisten the pastry dough, which could cause the pie to get soggy, whereas an oven will help crisp the dough.
Remove the pie from its packaging if it is a frozen pie. Whether you are reheating a homemade pie or heating a frozen pie, place the pie in an oven-safe baking dish.
Bake the steak pie in the oven between 20 and 30 minutes. One indication the pie is done will be that the crust will start to brown. If you have a meat thermometer, you can further ensure the steak inside of the steak pie is hot enough when its internal temperature reads above 62 degrees Celsius (145 degrees Fahrenheit).
Remove the steak pie from the oven and serve immediately.
