Preheat and Prep: Start by heating your oven to 375°F (190°C). While the oven warms up, take your Shepherd’s Pie out of the freezer and remove any plastic wrap or coverings.
Set Up for Success: If your pie isn’t already in an oven-safe dish, go ahead and transfer it. Cover the dish with aluminum foil, making sure it’s loose. This little tent keeps the top from getting too brown too quickly.
Bake: Place your dish in the oven and let it bake for about 60-75 minutes. Make sure the pie is heated all the way through.
Final Touch: For that irresistibly crispy top, take off the foil in the last 10-15 minutes of baking.
Cool and Serve: Once the top is golden and gorgeous, take your pie out of the oven. Let it sit for a few minutes (it’s hot!), then dive in and enjoy!
