Can I prepare these potatoes ahead of time?
Yes. Assemble the stuffed potatoes up to 24 hours ahead, cover tightly, and refrigerate. Add 10–15 minutes to baking time when cooking from cold.
What's the best way to get crispy potato skins?
Brush the halved potatoes with oil, place cut-side down on a baking sheet, and bake at 400°F for 15–20 minutes before filling to crisp the exterior.
Can I use ground turkey or lamb instead of beef?
Yes. Ground turkey works well for a leaner option; ground lamb is traditional for shepherd's pie and adds deeper flavor.
How do I know when the filling is cooked through?
The ground beef should be fully browned with no pink, and the beef broth should reduce until slightly thickened, about 8–10 minutes after simmering.
Can I freeze these after assembly?
Yes. Wrap individually in foil or place in an airtight container for up to 2 months. Bake from frozen at 350°F for 35–40 minutes, covered, until heated through.
