Cottage Pie for Busy Parents

Cottage pie is the kind of dinner that seems to have been designed with tired parents in mind. You can make it on Sunday, keep it in the fridge, and slide it into the oven on Tuesday while you sort out bath time. It feeds a crowd, reheats well, and almost every child likes mashed potatoes.

A quick note on names: in Britain, cottage pie is made with ground beef, while shepherd's pie is made with lamb. The two are often confused, especially outside the UK, but the difference is simple to remember once you know that shepherds look after sheep.

Where the vegetables hide

The filling starts like a good Bolognese, with onion, carrot and celery cooked slowly in a little oil. Grate the carrot rather than dicing it and it melts into the sauce, which is helpful if you have a child who picks out anything orange. A handful of frozen peas stirred in at the end adds color and sweetness. Mushrooms, finely chopped, bulk up the meat without changing the flavor much.

The sauce gets its depth from tomato paste, Worcestershire sauce and stock. Let it bubble until it is thick rather than soupy. A runny filling will seep up through the potato and turn the top soggy.

For a slightly different approach, the version from Easy Recipes is worth comparing, especially if you want to see how a British home cook handles the gravy and the ratio of meat to mashed potatoes.

The mashed potato topping

Use floury potatoes such as russets, which turn light and fluffy. Waxy potatoes give a gluey topping. Drain them well, let them steam dry for a minute, then mash with butter and warm milk. Some families stir in an egg yolk for a golden finish, or sprinkle grated cheddar on top. Either way, rough up the surface with a fork; the ridges catch the heat and become crisp.

A make-ahead plan

Here is one way to split the work over a week:

• Weekend: make the filling and the mashed potatoes, assemble the pie in a baking dish and let it cool completely.
• Fridge: cover tightly and keep for up to three days.
• Dinner night: bake straight from the fridge, adding 15 to 20 minutes to the time, until bubbling at the edges and hot in the middle.

Cottage pie also freezes well. Assemble it in a foil or freezer-safe dish, wrap it well and label it. Thaw it overnight in the fridge before baking. Individual portions in small containers are a lifesaver for nights when one parent is working late and the other is feeding the kids early.

Serve with steamed broccoli or green beans. A little extra ketchup on the side is not traditional, but it is very common at family tables, and we will not judge.
