Classic Cottage Pie

Ingredients

• 850 ml beef stock
• 1 .14 kg minced beef
• 2 cloves, minced
• 3 tbsp plain flour
• 1 tbsp tomato puree
• 3 carrots, diced
• black pepper
• thyme
• 2 onions, finely chopped
• 1 tbsp olive oil
• 3 tbsp olive oil
• 3 celeries, chopped
• 4 tbsp Worcestershire sauce
• 2 bay leaveses
• 1 potato, peeled and chopped
• 225 ml milk
• 25 g butter
• 200 g cheddar, grated
• Buttered peas and greens, to serve
• Dressed green salad, to serve

Method

1. Heat 1 tbsp olive oil in a large heavy pot over medium-high until it shimmers. Season the mince generously with salt and pepper, then brown in two batches — don't crowd the pan. All at once and the pan crowds, water comes out, and you've boiled the meat instead of browning it. You want a deep mahogany crust and proper stuck bits on the base of the pot. Lift each batch out with a slotted spoon and set aside.
2. Drop the heat to medium and add the remaining 3 tbsp oil. Tip in the onions, carrots and celery with a good pinch of salt and cook gently for 20 minutes, stirring now and then, until everything is soft and sweet and just starting to catch gold at the edges. The salt pulls the water out so the veg sweetens rather than steams.
3. Stir in the garlic and cook just until fragrant — 30 seconds, no more. Burnt garlic turns the whole dish bitter. Add the flour and tomato purée and stir for 2 minutes until everything is coated in a rusty paste — this cooks the raw flour out so the gravy tastes of beef, not paste.
4. Pour in the stock and Worcestershire sauce, scraping the brown stuck bits off the bottom of the pot — that fond is half the flavour of the finished pie. Return the beef along with the rinsed red lentils, tuck in the bay leaves and thyme, and bring to a gentle simmer.
5. Simmer uncovered for 45 minutes, stirring occasionally, until the sauce has thickened to a glossy, spoon-coating gravy and the lentils have melted into the meat. Fish out the bay and thyme stalks. Taste, season, taste again — adjust the salt and pepper now, not at the table.
6. While that's going, put the potatoes in a large pan and cover with cold water. Salt the water generously — it should taste like the sea. Bring to the boil and cook for 15–18 minutes until a knife slides through cleanly. Drain and let them steam-dry in the colander for a couple of minutes — wet potatoes make sad mash.
7. Tip the potatoes back into the pan. Warm the milk and butter together briefly, then pour over the potatoes and mash until smooth. Stir through three-quarters of the cheddar, a grating of nutmeg, and a good pinch of salt and pepper. Taste the mash — it should be properly seasoned on its own, before it ever meets the gravy.
8. Heat the oven to 220°C / 200°C fan / gas 7. Tip the beef into an ovenproof dish (or two smaller ones), spread the mash over the top in confident sweeps, then drag a fork across to rough up the surface — those ridges are what go crisp and golden. Scatter with the remaining cheddar.
9. Bake for 25–30 minutes, until the top is deep golden and the gravy is bubbling up around the edges. Let it sit for 5 minutes before serving — it'll be lava-hot.
10. Spoon onto warm plates straight from the dish, finish each portion with a crack of black pepper and a generous scatter of fresh chives over the bronzed, bubbling crust.
