Mrs Beeton’s famous Book of Household Management, published in 1861, included plenty of recipes for using up cold meat. Victorian cooks clearly had no plans to waste a single slice of Sunday’s joint.
A big roast feeds the table once, then quietly sets up the next day’s meals as well. Just chill leftovers within two hours, eat them within two days and reheat them only once.
That thrifty streak still makes sense when Monday rolls round and the fridge is full of foil parcels. Cold meat, stray potatoes and half a jug of gravy are not a problem to solve.
They're a head start on tea, and I love that idea more than I probably should. So which of yesterday's scraps is going to make tonight the best meal of the week?
1. Roast Beef Stroganoff
A dish with Russian roots turns out to be the slickest rescue for cold roast beef. The classic version uses quick-cooked strips of beef, and your Sunday leftovers are already cooked.
Start by frying sliced onions and chestnut mushrooms in butter until golden and slightly sticky. Add a spoonful of Dijon mustard, a pinch of paprika and around 150ml of beef stock, then let it bubble down a little.
Slice the beef thinly across the grain, because shorter fibres keep each bite tender. Stir it in for only a couple of minutes, since long simmering makes cooked beef tough and grey.
Take the pan off the heat before adding soured cream, or the sauce may split. Serve it over rice, buttered tagliatelle or even a pile of oven chips.
Make sure the beef is piping hot before it hits the plate. Tea on a Monday rarely tastes this smart for so little effort.
2. Bubble and Squeak
Few dishes are named after their own soundtrack, yet this one hisses and pops its way to fame. It's the godparent of every leftover roast idea, built on mash or crushed roast potatoes and cooked greens.
Cabbage is traditional, but sprouts, kale, carrots and peas all happily join in. Chop the veg small and squeeze out extra water, because wet greens stop the mix from browning.
Heat a splash of oil and a knob of butter in a frying pan over a medium heat. Press the mixture down firmly and leave it alone for a good few minutes.
That patience builds a deep brown crust, which is the whole point. Flip it in sections, scrape up the crispy bits, and fold them back through for extra crunch.
A fried egg and a splodge of brown sauce finish it nicely. Few plates feel more British, or more cheerful, on a grey start to the week.
3. Loaded Yorkshire Puddings
Edible bowls are rarely this useful, and a leftover Yorkshire pudding is basically a bowl waiting for a job. Fill it up and you've rebuilt Sunday in miniature.
Day-old puddings go soft in the fridge, so they need a blast to crisp up again. Pop them on a tray in an oven at 200°C for around five minutes.
Meanwhile, warm shredded meat, chopped roast veg and gravy together in a small pan. Heat it until it's steaming hot right through, then spoon it generously into each pudding.
Beef with horseradish is a classic pairing, though chicken with stuffing crumbs works just as well. A spoonful of cauliflower cheese makes a rich filling for anyone skipping meat.
Eat them fast, because gravy gets the upper hand on batter within minutes. Knives and forks are optional for the brave.
It's the closest thing to a Sunday roast you can have without peeling a single potato.
4. Lamb Shepherd's Pie
Shepherds look after sheep, which is exactly why this pie should be made with lamb. Leftover roast lamb gives it a deeper, richer flavour than raw mince often manages.
Shred or finely chop the meat, then cook it with softened onion, carrot and a little thyme. Add leftover gravy or some stock and a spoonful of tomato purée, letting it thicken nicely.
Floury potatoes such as Maris Piper or King Edward make the fluffiest mash. Beat them with butter, milk and a handful of mature cheddar for a crust that browns well.
Spread the mash over the filling and drag a fork across the top. Those ridges catch the heat and turn crunchy in the oven.
Bake at around 200°C for 25 to 30 minutes, until bubbling at the edges and piping hot in the middle. It even freezes well before baking, so a second pie could sort out next Monday too.
5. Chicken and Leek Pie
Leeks and chicken have been sharing pie dishes in Britain for a very long time, and leftovers make the job quicker. The roasting has already been done for you.
Soften sliced leeks in butter until silky, then stir in a tablespoon of plain flour. Pour in about 300ml of chicken stock and a splash of milk, stirring until thick and glossy.
Add shredded roast chicken and a little chopped tarragon or parsley. Let the filling cool before topping it, because hot filling turns pastry soggy and sad.
Ready-rolled puff pastry makes a quick lid, and brushing it with beaten egg gives a shiny finish. Cut a small slit in the top so steam can escape.
Bake at 200°C for around 25 minutes, until puffed and golden. Check the filling is piping hot in the centre before serving.
Mash and peas are the classic sidekicks, and nobody has ever complained about a pie on a Monday.
6. Roast Pork and Crackling Sandwich
Crackling is the first thing to vanish from a Sunday table, so hiding a few pieces is a smart move. Your Monday sandwich will thank you for the forward planning.
Slice the cold pork thinly and warm it gently in a pan with a splash of leftover gravy. That stops it drying out and gives the bread something tasty to soak up.
A soft white bap or a crusty roll works best here. Spread one side with apple sauce, because its sharp sweetness cuts through rich pork perfectly.
Crackling that has gone chewy can be revived in a hot oven or under the grill. Watch it closely, as it can catch quickly and spit hot fat.
A smear of sage and onion stuffing adds a herby layer if any survived. Serve a little pot of gravy on the side for dipping.
Messy fingers are part of the deal, and frankly worth it.
7. Roast Beef Hash
Hash comes from the French word hacher, meaning to chop, which tells you most of what you need to know. Chop, fry and enjoy the crispy reward.
Cut leftover roast potatoes into small, even cubes so they brown at the same speed. Fry them in a little oil in a hot frying pan, turning only now and then.
Add chopped onion and maybe some peppers once the potatoes start colouring. Diced roast beef goes in last, because it only needs heating until it's piping hot.
A dash of Worcestershire sauce brings a tangy, savoury kick. Season well, since cold potatoes soak up salt surprisingly fast.
Crack a couple of eggs into wells in the hash and cover the pan for a few minutes. The whites set while the yolks stay soft, giving you a ready-made sauce.
Breakfast, lunch or tea, it suits whichever slot Monday has free.
8. Chicken Arancini
Arancini means little oranges in Italian, thanks to their round shape and golden colour. Here they become a crafty home for the last scraps of roast chicken.
The secret is cold risotto, because warm rice is too soft to shape. Make a simple risotto with chicken stock and Parmesan, then chill it overnight.
Stir in finely chopped chicken and a little crumbled stuffing if you have some. Roll into balls and push a small cube of mozzarella into each centre.
Coat them in flour, beaten egg and breadcrumbs. Deep-fry in rapeseed oil at around 175°C until deep golden and hot right through.
Hot oil deserves respect, so use a deep, heavy pan and never leave it unattended. A cooking thermometer takes the guesswork out of it.
Rice that is cooked and cooled should be chilled quickly and eaten within a day. Serve with a simple tomato sauce for dunking.
9. Spiced Lamb Samosas
Folding a samosa feels like origami, only far tastier when you get it wrong. Leftover lamb takes to spices brilliantly, so the filling practically writes itself.
Fry a chopped onion with garlic, ginger, cumin, ground coriander and garam masala. Add finely chopped lamb, a handful of frozen peas and a little diced cooked potato.
Cook the mixture until fairly dry, since a wet filling makes soggy pastry. Let it cool fully before you start folding.
Filo pastry or spring roll wrappers save loads of time. Cut them into strips, add a spoonful of filling, and fold into tight triangles.
Brush with melted butter and bake at 200°C for around 20 minutes until crisp. A dip of yoghurt mixed with chopped mint and a squeeze of lime cools things down.
Filo contains wheat, so pick suitable wrappers for anyone avoiding gluten.
10. Turkey Curry
Boxing Day turkey curry is practically a national pastime, but roast turkey crowns aren't only for Christmas. Roast chicken works just as happily in this pot.
Build the sauce first, as the meat only needs reheating. Fry onion, garlic and ginger slowly until soft and golden, then add curry paste or your own spice mix.
Pour in a tin of chopped tomatoes or coconut milk and simmer for 15 minutes. That time lets the spices mellow and the sauce thicken properly.
Stir in chunks of cooked turkey and heat for around five to ten minutes. Make sure it's piping hot all the way through before serving.
Leftover roast parsnips or sprouts can go in too, adding sweetness and bite. Finish with chopped coriander and a squeeze of lemon.
Rice, naan or a stack of poppadoms complete the job. Leftovers have rarely sounded this far from the dining room.
11. Cheesy Chips And Gravy
Chips, cheese and gravy is a beloved chippy order across the north of England. Leftover roast potatoes make a crunchier version without any deep frying.
Cut the potatoes into thick chunks so more surface can crisp. Roast them at 220°C for 15 to 20 minutes, or use an air fryer, until craggy and golden.
Heat leftover gravy in a small pan until it's bubbling hot. Gravy containing meat juices should always be reheated properly, not just warmed.
Pile the potatoes into a bowl and scatter grated mature cheddar on top. Pour the hot gravy straight over so the cheese starts to melt.
A sprinkle of chopped spring onion adds freshness and a bit of colour. Eat it with a wooden fork from paper if you want the full seaside feel.
It's honest, unashamed comfort food, and Monday deserves exactly that.
12. Chicken and Vegetable Pasta Bake
Penne has a knack for catching sauce in its tubes, which makes it the hero of any good bake. Leftover chicken and veg simply hitch a ride.
Make a white sauce with 40g butter, 40g plain flour and around 500ml of milk. Whisk steadily over a medium heat until thick and smooth.
Stir in grated cheddar and a teaspoon of mustard for extra tang. Add shredded chicken and any chopped leftover veg, like broccoli, carrots or sprouts.
Cook your pasta for a couple of minutes less than the packet says. It will finish softening in the oven and won't go mushy.
Mix everything in an ovenproof dish and top with more cheese and breadcrumbs. Bake at 200°C for 20 to 25 minutes, until golden and bubbling.
Check the middle is piping hot before scooping. Seconds tend to be claimed quickly, so serve fast.
13. Stuffing and Pork Sausage Rolls
Sausage rolls disappear at parties at alarming speed, and these clever ones use up spare stuffing too. Sage and onion stuffing tastes right at home beside pork.
Mix around 400g of pork sausagemeat with crumbled leftover stuffing. Chopped roast pork can join in, adding texture and a meatier bite.
Lay the filling along a sheet of ready-rolled puff pastry. Roll it up, seal the edge with beaten egg, and cut into short lengths.
Brush the tops with more egg and add a few sesame seeds if you like. Bake at 200°C for 25 to 30 minutes until puffed and deep golden.
Raw sausagemeat needs to be fully cooked, so check there's no pink in the centre. Cranberry sauce or a sharp chutney makes a cracking dip.
They're just as good cold the next day, which makes Tuesday's lunchbox sorted.
14. Root Vegetable Gratin With Stilton
Stilton can only be made in Derbyshire, Leicestershire and Nottinghamshire, which gives this gratin a properly local swagger. It turns leftover roast roots into a dish worth sitting down for.
Slice leftover parsnips, carrots and potatoes into rough rounds. Layer them in a buttered ovenproof dish, mixing colours as you go.
Make a quick white sauce and crumble in about 100g of Stilton until melted. Mature cheddar works too if blue cheese feels too strong.
Pour the sauce over the vegetables and top with breadcrumbs and chopped walnuts. Leave the nuts off if anyone at the table has an allergy.
Bake at 190°C for around 25 minutes until golden and bubbling at the sides. The roasted veg are already sweet and caramelised, so the salty cheese balances them neatly.
Serve with leftover ham or a crisp green salad. Humble roots have never looked so pleased with themselves.
15. Roast Potato Fritters
Cold roast potatoes are a bit stiff in the fridge, but that firmness makes them brilliant for fritters. They hold together well and crisp up fast.
Roughly crush the potatoes with a fork, leaving some chunky bits for texture. Mix in softened leeks, chopped spring onion and any stray greens.
Bind with one beaten egg and a couple of tablespoons of plain flour. A little grated cheese or a pinch of smoked paprika adds a savoury lift.
Shape into small patties and chill for ten minutes if they feel loose. That rest helps them keep their shape in the pan.
Shallow-fry in rapeseed oil over a medium heat for three or four minutes each side. Drain on kitchen paper and serve with a poached egg or a dollop of soured cream.
These make Monday brunch look like you planned it all along.
16. Chicken Caesar Salad With Roast Potato Croutons
Caesar salad is said to have been created in Mexico in the 1920s by a restaurateur named Caesar Cardini. He probably never pictured roast potatoes stepping in as croutons.
Cube your leftover potatoes and toss them in a little oil and salt. Roast at 220°C for 15 minutes or so, until the edges turn crunchy.
Tear crisp Cos lettuce into a big bowl and add shredded cold roast chicken. Cold chicken is fine straight from the fridge, as long as it was chilled promptly after Sunday lunch.
Classic Caesar dressing uses raw egg yolk and anchovies. Choose British Lion eggs if serving pregnant guests, and skip the anchovies for anyone with a fish allergy.
Toss everything together, then pile on Parmesan shavings and the hot, crunchy potatoes. It’s the freshest finish to a weekend roast, and a fine reason to look forward to Monday.
