Cottage Pie

Cottage pie is what shepherd's pie is called when it is made with beef instead of lamb, and it is one of the cheapest ways to turn a single pound of ground beef into a full dinner. A savory beef and vegetable base gets topped with a thick layer of mashed potato and baked until the top is golden. No pastry, no pie crust, just a pound of beef and a pot of potatoes doing all the work for about $1.56 a serving.

1 How to make it

1

Boil the potatoes

Cover the diced potatoes with cold water in a pot, salt the water, and bring to a boil. Cook 12 to 15 minutes until a fork slides in easily. Drain well, since watery potatoes make a runny mash.

2

Brown the beef

While the potatoes cook, heat the oil in a large skillet over medium-high. Add the beef, onion, and garlic with a pinch of salt and cook 6 to 8 minutes, breaking up the meat, until browned and the onion is soft.

3

Build the filling

Stir in the Worcestershire sauce and tomato paste and cook a minute so the paste loses its raw edge. Pour in the beef broth and simmer 3 to 4 minutes until slightly thickened. Fold in the frozen peas and carrots, season with thyme, salt, and pepper, then spread the filling in a baking dish.

4

Mash the potatoes

Mash the drained potatoes with the butter and milk until smooth, and season with salt. A thicker mash holds its shape better on top of the filling than a thin one.

5

Top and bake

Spread or pipe the mashed potato evenly over the filling, all the way to the edges to seal it in. Rough up the surface with a fork for extra crisp ridges. Bake at 400 F for 20 to 25 minutes, until the top is golden and the filling bubbles at the edges.

6

Rest before serving

Let the pie sit for 5 minutes before scooping. The filling is molten straight from the oven and firms up slightly as it rests, which keeps each serving neat instead of runny.

2 Cheaper ingredient swaps

  • Ground turkey for beef. Turkey works the same way and can be cheaper some weeks. Add a splash of oil to the pan since it is leaner and browns drier than beef.
  • Frozen mixed vegetables for peas and carrots. Any bag of frozen vegetables works in the filling. Use whatever is already in the freezer.
  • Instant mashed potato flakes for fresh. A box of flakes prepared according to the package saves the boiling step on a busy night, though fresh potatoes are usually cheaper per serving.
  • Shredded cheddar on top. A handful of cheese sprinkled over the mash in the last 5 minutes of baking browns into a crust, if you have some to use up.

3 Budget tips

  • One pound of ground beef stretches across six servings here because the potato topping does half the work of filling the plate, which is the whole appeal of cottage pie.
  • Buy potatoes in the 5 or 10 pound bag. The per-pound price drops sharply over the small bags, and this recipe only needs 2 pounds of the bag.
  • Make the filling and mash separately the night before, then assemble and bake straight from the fridge, adding about 10 minutes to the bake time.

4 Storage, freezing & reheating

Fridge

Refrigerate leftovers covered or in an airtight container for up to 4 days. The flavor improves on day two once the filling has had time to set.

Freezer

Freeze the fully assembled, unbaked pie for up to 3 months. Bake from frozen at 375 F for about an hour, or thaw overnight in the fridge first and bake as directed.

Reheating

Reheat individual portions in a 350 F oven for about 15 minutes so the top re-crisps, or microwave for 2 to 3 minutes if you do not mind a softer top.

6 Frequently asked questions

What is the difference between cottage pie and shepherd's pie?

Traditionally shepherd's pie is made with ground lamb and cottage pie with ground beef. In American kitchens the names are often used interchangeably for the beef version, which is exactly what this recipe is.

Can I make cottage pie ahead of time?

Yes, and it is one of the better make-ahead dinners. Assemble the filling and mashed potato topping, refrigerate unbaked for up to a day, then bake straight from the fridge, adding a few extra minutes to the bake time.

Why is my cottage pie watery?

Usually undrained potatoes or a filling that was not simmered long enough to thicken. Drain the potatoes well before mashing, and let the beef broth reduce for a few minutes before topping with the mash.

How is the price per serving figured?

About $9.34 for the whole dish, split across six servings, which is roughly $1.56 each. The pound of beef and the potatoes are the two main costs, so a sale on either brings the number down further.
