This Healthy Shepherd's Pie calls for olive oil instead of butter, extra-lean ground beef, lots of vegetables, and a cauliflower-potato mash topping for a lighter take on the classic that's still FULL of flavor!

My family has deep roots in Ireland and the British Isles, so having a shepherd’s pie on the table always feels like home. It’s true comfort in a one-dish meal, with savory meat and vegetables on the bottom and a crusty crown of mashed potatoes on top.

It’s also a dish that’s on the heavy side, something that might require a nap after eating. So I’ve retooled the recipe, making it healthier, yet every bit as comforting as you’d expect from a meat and potato pie.

HOW THIS PIE IS DIFFERENT FROM TRADITIONAL SHEPHERD’S PIE

The shepherd’s pie of my upbringing features a hefty portion of meat, with vegetables playing a supporting role, and a thick topping of buttery mashed potatoes. My updated version bumps up the ratio of vegetables to meat and calls for extra-lean ground beef, which is the leanest option in the butcher case.

For the mashed potatoes, the recipe swaps in olive oil for butter, which means more heart-healthy fats in every bite. The sum total of these swaps is a lighter dish with no shortcuts on flavor.

THE SPECIAL TOPPING: CAULIFLOWER AND POTATO MASH

One other change from traditional shepherd’s pie is the topping: It’s a blend of cauliflower and potatoes! This means fewer carbs and calories (for those of you tracking), but more importantly, the added health benefits of cauliflower.

The recipe calls for sharp or extra-sharp cheddar cheese, which plays off of the cauliflower and adds a pleasing crust when baked.

SUGGESTIONS AND SUBSTITUTIONS FOR SHEPHERD’S PIE

A true shepherd’s pie is actually done with lamb, not beef (shepherds herd sheep and lamb, after all). Cottage pie is the term traditionally applied to one made with beef.

Regardless of what you call it, you can make this with basically any type of ground meat you like, knowing that they range widely in fat content. Ground lamb, turkey, bison, venison, and beef—or half and half of any of the above—are all fair game.

Nothing beats fresh vegetables and cheese you’ve grated on the spot to make this recipe, but if you’re short on time, here are a few shortcuts:

Swap in frozen mixed vegetables for the carrots, celery, and peas. Use two and a half cups and add them to the dish when it instructs you to add the peas.

Use two and a half cups and add them to the dish when it instructs you to add the peas. Use pre-shredded sharp cheddar . Take a gander at the ingredients, since some brands use additives to keep the cheese from clumping. Less is more, if you ask me.

Every little bit counts when it comes to saving time. Plus, fussing with a bottle opener isn’t my favorite pastime. You don’t need fancy wine for this anyway, just something dry and drinkable.

MAKE-AHEAD TIPS FOR HEALTHY SHEPHERD’S PIE

There’s no doubt that shepherd’s pie involves labor. Luckily, you can do some of the prep in advance, so it goes more quickly come dinnertime.

Cut all of the vegetables ahead of time, including the onions, carrots, celery, and cauliflower. You can also peel and cut the potatoes, being sure to store them in a bowl covered with water to prevent them from greying. Keep all prepped vegetables in the fridge until ready to cook.

The dish is also one you can assemble completely and then refrigerate before baking. Once assembled, let it cool completely, wrap in plastic, and store in the refrigerator for up to two days. When it’s time to bake, put it straight from fridge to oven and tack an additional 10 to 15 minutes to the cooking time.

The finished dish keeps well for several days and reheats well in the oven or microwave.

HOW TO FREEZE HEALTHY SHEPHERD’S PIE

Once the shepherd’s pie is baked, cool completely and cover loosely with plastic wrap. Place it in the freezer until fairly firm, about two hours. Then, cover tightly with plastic wrap, followed by aluminum foil. Mark the date on the outside and store in the freezer for up to two months.

When ready to serve, remove the foil and plastic wrap. Use the foil you just removed to loosely cover the pie. Make sure that your casserole dish can go straight from freezer to oven; if not, set the casserole in the oven while the oven preheats so that the dish warms slowly.

Bake the casserole for an hour, or until the pie is hot all the way through. Remove the foil for the last 15 minutes to allow the top to brown.
