Quick Shepherd's Pie Stuffed in Crispy Potato Skins

These Shepherd's Pie Potato Skins use edible potato bowls instead of a regular casserole pan. Microwaving the whole potatoes saves time while you simmer the lamb or beef on the stove. Once you pack the vegetables and meat inside, they just need 15 to 20 minutes at 350°F (180°C) to bake.

Potato Shells & Mash

You need four large potatoes for this recipe. You must prick the whole potatoes multiple times with a fork before you start. This lets steam escape during cooking. You will microwave the potatoes on high for five minutes, turn them over, and microwave them for another five minutes. A knife inserted into the center should meet no resistance. You can bake the whole potatoes in the oven for 40 to 50 minutes at 350°F (180°C) instead of using the microwave.

You need to let the cooked potatoes rest off the heat for a few minutes. You should protect your hands with a folded kitchen towel when handling them. You will cut off the tops and scoop out the center of each potato. Leave a border of about 0.2 inch (0.5 cm) around the inside. This thick edge maintains structural integrity so the shell holds its shape.

You place the scooped out potato flesh in a bowl. You add the milk, butter, and salt. You mash the mixture until it is smooth and reaches your preferred texture.

Beef or Lamb Filling

Traditional Shepherd's pie uses ground lamb. You can substitute ground beef, which turns the meal into a Cottage pie. You heat olive oil in a pan over medium high heat and sauté diced onion and minced garlic until soft. You turn the heat up to high and add your chosen meat. You cook and break up the meat for three minutes until it carries a brown color.

You sprinkle flour over the meat and stir the mixture to combine. This flour thickens the liquid later. You pour in the beef stock, water, frozen mixed vegetables, dried thyme, dried oregano, salt, and pepper. Frozen mixed vegetables like corn, peas, and carrots save preparation time compared to fresh produce. Fresh chopped vegetables can replace the frozen mix if you prefer. You stir the sauce well and simmer it for two minutes until it looks thick and glossy.

Assembly & Baking

You spoon the meat mixture directly into the empty potatoes. You should pack the meat filling tightly into the hollowed potato halves before adding the topping. Let the meat form a small heap at the top of the shell.

Cover the meat by piping the mashed potato through a pastry bag fitted with a wide star nozzle, or simply portion it out with a spoon. Run a fork across the topping to build small ridges, which will turn brown and get crispy as the meal bakes. You can sprinkle some parmesan over the mash to provide an extra crunch. Because this process usually produces more mashed potato than the shells can hold, you can dish out the remaining amount on the side of the completed plates.

You place the assembled potatoes on a baking tray. You bake the fully assembled skins to develop the flavor of the filling, rather than just broiling the top. You pull them out of the oven when they catch some golden color on the peaks. The assembled skins can brown under a broiler instead of baking if your time is limited.

Storing leftovers

You should freeze the potato skins only after baking them. If you cover unbaked assembled skins with plastic wrap, the wet mashed potato will stick to the covering. You can store the baked skins in an airtight container. You thaw frozen skins completely before reheating. You can reheat them in the oven to restore a crispy top, or reheat them in the microwave for a faster meal.
