Cottage Pie

Ingredients

Equipment Needed

• •Wide, heavy-bottomed frying pan or casserole
• •Large ovenproof dish, roughly 25cm by 20cm
• •Potato masher
• •Large saucepan for the potatoes

Instructions

1. 1

   Brown the mince

   Get a wide, heavy pan properly hot with a glug of olive oil. Add the mince in two batches, spreading it out in a single layer and leaving it alone. Don't stir. Don't fuss. You want it to catch and colour on the bottom, not steam in a grey huddle. When it has a good brown crust underneath, break it up and turn it. This takes four or five minutes per batch. Tip it onto a plate and set aside.

   Two batches, not one. Overcrowding the pan drops the temperature and the mince stews rather than fries. The browning is where most of the flavour lives. Don't skip it.
2. 2

   Soften the vegetables

   In the same pan, add a little more oil if needed and turn the heat down. Add the onion, carrot, and celery with a pinch of salt. Cook gently for ten minutes or so, stirring now and then, until everything has softened and the onion has gone translucent and sweet. Add the garlic for the last minute. It should smell warm and round, not sharp.

3. 3

   Build the filling

   Stir the tomato purée into the vegetables and let it cook for a minute, darkening slightly and losing its raw edge. Sprinkle over the flour and stir it in. Return the browned mince to the pan with any resting juices. Pour in the stock and add the Worcestershire sauce, bay leaves, and thyme. Give it a good stir, bring to a gentle simmer, and let it bubble quietly with the lid slightly ajar for twenty-five to thirty minutes. The liquid should reduce and thicken until the filling is rich and saucy but not swimming. Season it well. Taste it. If it tastes like it needs something, it probably needs more salt.

   The filling should be savoury and deep, not watery. If it still looks loose after thirty minutes, take the lid off and let it reduce for a few minutes more. A wet filling makes a soggy top, and that is not what we are after.

   Make the mash

   While the filling simmers, boil the potatoes in well-salted water until they yield completely to a knife, with no resistance at all. Drain them thoroughly and let them sit in the colander for a minute to steam dry. Return them to the warm pan and mash with the butter and warm milk until smooth and giving. Season with salt, pepper, and a grating of nutmeg. The mash wants to be soft enough to spread but firm enough to hold its shape on top. If it's too stiff, add another splash of milk. If it's slack, you've gone too far with the liquid, but it will firm up in the oven.

   Floury potatoes are essential. Maris Piper or King Edward. Waxy varieties make gluey mash, and no amount of butter will fix that. The potato does the work here.

   Assemble the pie

   Set the oven to 200C/180C fan. Fish out the bay leaves and thyme stalks from the filling and spoon it into a large ovenproof dish, roughly 25cm by 20cm. Spread the mash over the top, starting at the edges and working inward so it seals against the sides of the dish. This stops the filling from bubbling over. Use a fork to rough up the surface. Those peaks and ridges are what turn golden and crisp. Dot a few small pieces of butter over the top if you like.

6. 6

   Bake until golden

   Bake for twenty-five to thirty minutes, until the mash has gone properly golden on top and the filling is bubbling up around the edges. You'll hear it before you see it, a gentle, sticky bubbling from inside the oven. Let it sit for five minutes once it's out. The filling needs a moment to settle, and it's too hot to eat straight away, though someone will always try.

Chef Tips

• •Don't buy lean mince for this. You want some fat in there, around 15-20% if you have the choice. The fat keeps the filling moist and carries flavour. If you trim all the fat away, you'll spend the rest of the recipe trying to put richness back in. Start with a good ingredient and the dish does most of the work for you.
• •Worcestershire sauce is a quiet miracle in a cottage pie. Not enough to taste it distinctly, just a splash to deepen everything around it. If you can identify the Worcestershire sauce, you've used too much. It should be a background note, not a soloist.
• •Make two and freeze one. A cottage pie assembled but unbaked, wrapped tightly and frozen, is worth more to your future self than almost anything else in the freezer. Cook it from frozen at 180C for about an hour, covering with foil for the first half so the mash doesn't catch before the filling heats through.
• •Leftover filling, if you've made extra, is very good on toast the next day. This is the kind of information that doesn't make it into most recipes but probably should.

Advance Preparation

• •The filling can be made a day ahead and refrigerated. It thickens as it cools, which makes assembly easier. The mash can be made a few hours ahead and reheated gently with a splash of milk before spreading.
• •Assembled but unbaked, the pie freezes well for up to three months. Wrap tightly in foil. Cook from frozen at 180C/160C fan for fifty minutes to an hour, covering for the first half.
• •Once baked, leftovers keep in the fridge for two days. Reheat portions in a moderate oven rather than the microwave. The mash stays better that way.
