Cottage Pie
Lean-mince, veg-loaded cottage pie using a sachet mix (or a quick homemade one). Cook it tonight in one large tray, or portion into individual foil trays and freeze uncooked for later.
Serves 4 · Cook 90 min

Ingredients
- 500g 5% lean beef mince
- 1 sachet cottage/shepherd's pie mix (Colman's or Schwartz), made up per packet (or the homemade mix below)
- 1 onion, grated or finely chopped
- 2 carrots, diced small (or 1 tin carrots, drained and chopped)
- 100g frozen peas
- 1 tbsp tomato purée (optional)
- Splash of Worcestershire sauce (optional)
- Pepper to taste (the sachet is salty enough)
- Splash of oil, for frying
- 900g potatoes (Maris Piper or similar), peeled and chunked
- 25g butter
- Splash of semi-skimmed milk
- Salt and pepper
- Optional: small handful of grated cheese for the top
- No sachet? Homemade mix: 1 tbsp plain flour, ½ beef stock cube in 300ml water, 1 tsp dried thyme, 1 bay leaf, ½ tsp garlic powder, a splash of Worcestershire (or soy/brown sauce) and plenty of pepper
Method
- Put the potatoes in a pan of cold salted water, bring to the boil and simmer 15–20 min until a knife goes through easily.
- Meanwhile, grate the onion (coarse side of a box grater) and dice the carrots small — or drain and chop the tinned carrots. Heat a splash of oil in a large pan over medium heat (hob 5–6) and cook the onion and carrot 4–5 min until softened and the raw onion bite has gone.
- Turn up the heat (hob 7–8), add the mince and brown it, breaking it up with a spoon — 6–8 min until no pink remains. Tip off any liquid.
- Stir in the tomato purée and Worcestershire sauce, if using, then add the sachet mix made up with the water the packet asks for. Bring to a simmer and cook 10–15 min (hob 4–5), stirring now and then, until thickened. Stir the peas through for the last 2 min. Season with pepper.
- No sachet? Instead of the sachet, stir the flour into the browned mince for a minute, then add the stock, thyme, bay leaf, garlic powder, Worcestershire and pepper. Simmer 10–15 min (hob 4–5) until thick — lid off for a few more minutes if it's loose — stirring the peas through for the last 2 min. Fish out the bay leaf, then taste: stock cubes are low-salt, so add a pinch of salt if needed.
- Drain the potatoes and let them steam dry in the colander for a minute. Mash with the butter, milk, salt and pepper until smooth.
- Let the filling cool 10–15 min so the mash sits on top rather than sinking in.
- Assemble in one large foil tray, or four individual foil trays to freeze: filling on the bottom, mash spooned over, roughed up with a fork. Cheese on top if using.
- To cook now: bake at 200°C fan for 25–30 min until the top is golden and the filling bubbles at the edges. Serve with green veg (broccoli, green beans or a pile of peas).
- To batch and freeze: use a quarter of the mix per individual tray (about 220g filling + 225g mash), but do not bake. Cool completely on the side (about an hour), cover tightly with foil, label with the date and freeze. Keeps 3 months.
- To cook a frozen portion: defrost overnight in the fridge, then bake at 200°C fan, foil off, for 30–35 min until golden, bubbling at the edges and piping hot in the centre. Don't cook from frozen (the top over-browns before the middle is hot), and foil trays are oven only.
