Lifting the lid on how to be slow cooker savvy...

"Slow cookers use very little electricity and - even when I didn’t have a working oven - it meant that I could prepare the day’s main meal in the morning while everyone was still in good form, all ready for the 5pm small-child-horrors," says Caroline.

There’s a nip in the air - the perfect opportunity for steaming bowls of veggie soup, warming dishes of lamb curry and lots of gloriously cosy casserole cooking. I could say that this is the time of year when I pull out the slow cooker - but that would be a lie. My slow cooker, one of them at least, has had a permanent position next to my cooker for 10 years now. I use it all year round, from poaching chicken in the summertime, making nutty granola for Christmas gifts, hot chocolate for winter afternoons or spiced apple butter from seasonal gluts. It’s an all-year-round workhorse that has more than earned its place in my kitchen.

That slow cooker is a 3-litre cheapie, picked up second-hand for a tenner from classified ads website Gumtree back in 2010. It didn’t get much use initially but in 2011 I realised what it was for. That year we had to move house with a toddler and my rapidly growing bump while renovating our nineteenth century cottage. Meanwhile the Kiwi in the house was setting up a company, which involved his business partner living with us for half the week, so I very quickly learned how to use the slow cooker to feed everyone on a very tight budget with the minimum of effort.

Slow cookers use very little electricity and - even when I didn’t have a working oven - it meant that I could prepare the day’s main meal in the morning while everyone was still in good form, all ready for the 5pm small-child-horrors. I was officially in love and have remained so ever since. For a small amount of work, there’s a big pay off. Coming home after a busy day to the rich, savoury aroma of dinner cooking is an instant mood-enhancer. It’s a no-fuss way of cooking, easy and economical for mid-week dinners and a hands-off way of feeding a crowd. Get slow cooker savvy with a few hard-learned tips and tricks from my experience.

Size matters 

Slow cookers vary in price, from simple €20, 4-setting (on-low-high-warm) models to all bells and whistles multi-cookers that have lots more functions - and cost much more. You don’t need sear functions - that’s what a regular hob is for - but timers and delay functions can be useful, depending on the way that your day works and when you want to use the slow cooker. 

Size-wise, a 3-litre or 3.5-litre slow cooker is perfect for four people and it’s also big enough for a loaf of bread, a small joint of beef or lamb or - just about - a whole chicken.

A few years ago, I also picked up a larger model at a German discounter. Twice the size of my original, it’s perfect for when there’s extra family and friends around. While the smaller one is great for cooking curries for our family of four, or rice pudding for smallies coming in after school, that monster makes short work of a hefty 2kg brisket, pork shoulder or large leg of lamb.

What types of meat to use 

There’s one simple rule of thumb: the cheap cuts are the best slow cooking cuts. Cooking at a low temperature over a prolonged period of time renders even the most unpromising pieces of meat into something tender and luscious. Think pork shoulder for the easiest pulled pork, lamb hearts (cook them in a tagine, shred before serving and no one will be any the wiser!) and shanks, beef cheeks - the low, slow cooking renders these particularly unctious - shin, oxtail and brisket. Chicken thighs work better than breasts and black pudding melts down to enrich any sauce, which is especially good if you’re trying to bulk up a bean casserole on a budget.

Five top tips 

1. Read: if you’re a newbie, get a good slow cooker recipe book. Slow Cooked by Miss South (Ebury Press) looks outside the ordinary for some brilliant and economical dishes, and British writer Sara Lewis (Hamlyn) has a handful of great slow cooker books that won’t see you wrong.

2. Prep: to brown or not to brown? Frankly, if I’m organised enough to chop onions in the morning before work I’m doing really well. I’m not going to be digging out the frying pan as well. Browning meat and veg can add an extra layer of flavour - but it’s definitely not essential. Especially not at 7am. Save these recipes for days when you have more time.

3. Ingredients: this is where simple, inexpensive ingredients can really shine. Cheap cuts of meat, root veg and pulses are great slow cooker staples. Season aggressively and add lots of flavour with spices - slow cooker tagines, dals and curries all get the thumbs up in my house.

Very important: don’t be tempted to use too much liquid or you’ll water down the flavours.

4. Cook: leave it alone. The slow cooker works by turning liquid into steam which condenses on the lid and falls back into the pot. Every time you open the lid to see what’s happening, you’re allowing steam to escape and slowing down the cooking time. A watched pot, and all that. Observe through the lid.

5. Finish: if your dish is too watery, cook on high with the lid off and allow the extra liquid to evaporate, or thicken with cornflour mixed with a little water. Be sure to taste before serving and season appropriately. 

Good last minute flavour enhancers to stir in include: marmite, balsamic vinegar, pomegranate molasses or a simple squeeze of lemon juice. Final touches like chopped herbs, a drizzle of yoghurt, or crunchy croutons will elevate a brown, boring-looking dish from good to great.

After-school slow cooker rice pudding

Best made in a small-ish slow cooker (3-litre or 3.5-litre for preference) or it will cook too fast. I normally put this on before we leave the house at 9am and the girls fall on it at 3pm. 

Ingredients (Serves 2 starving children.)

A knob of butter 

75g  pudding rice 

500ml milk 

1 tablespoon brown sugar 

1/2 teaspoon vanilla extract


  • Butter the inside of a slow cooker bowl generously. Pop in the pudding rice, milk, brown sugar and vanilla. Stir.
  • Replace the lid and cook on low for 6 hours, or until the rice is soft and has absorbed the milk. Stir again, adding an extra splash of milk if needed. Serve with a dab of jam

or some dark chocolate grated on top.

Slow cooked butter beans 

Fancy a Sunday morning brunch treat? Set the slow cooker going before you go to bed and wake up to this feast, which tastes great with any combination of toast, bacon, sausages and eggs. It makes a big pot of beans but any leftovers are gorgeous on baked potatoes and also freeze well.

Ingredients (Serves 6-8)

500g dried butter beans 

2 onions, sliced 

3 cloves garlic, finely chopped 

3 cloves 

2 bay leaves 

2 tablespoons tomato purée 

1 tablespoon cider vinegar 

3 tablespoons molasses 

1 tablespoon Dijon mustard 

2 teaspoons smoked paprika 

Freshly ground black pepper, sea salt 


  • Bring the butter beans to the boil on the hob for 10 minutes, drain and place in the slow cooker pot.
  • Add the onions, garlic, cloves and bay leaves. Measure the tomato pureé, vinegar, molasses, mustard and paprika into a jug, add 250mls of water and whisk well. Tip over the beans, add another litre of water to the pot (that’s 1.250mls in total), pop on the lid and cook for 8 hours on low until the beans are tender.
  • If there’s too mu

ch liquid, cook for the last hour on high with the lid off. Taste and season - beans need a lot of salt - and serve.

Cinnamon pecan granola 

I like my granola with lots of nuts and no dried fruit. I make this in batches for family at Christmas time. They’re very good at handing back the jars for refills.


375g rolled oats 

125g pecans 

50g brown sugar 

1 teaspoon cinnamon 

¼ teaspoon salt 

120ml olive oil 

120ml maple syrup 

1 teaspoon vanilla extract 


  • Measure the oats, pecans, brown sugar, cinnamon and salt into the slow cooker bowl. Add the olive oil, maple syrup and vanilla and mix everything together thoroughly. Cover the top of the bowl with a clean, dry tea towel and put the lid on, slightly askew to allow for air circulation.
  • Cook on high for 2-2½ hours, stirring every 30 minutes, until toasted and golden. Spread on a baking tray to cool and crisp. Store in an airtight jar or container.
  • Spiced apple butter Apple butter - essentially super-concentrated stewed apples - is the best way of using up autumn apples. I spread it on scones instead of jam, serve with cheese or use it to glaze pork chops. I make this in my large 6.5-litre slow cooker. Makes approximately 1.5kg.
  • 3 kg apples, peeled, cored and sliced 100g demerara sugar 1 teaspoon ginger ¼ teaspoon salt 1 cinnamon stick 2 star anise 3 cloves 1 tablespoon cider vinegar Add all ingredients, apart from vinegar, to the bowl of a large slow cooker. Cook on low for 10-12 hours until the fruit is dark brown and disintegrating.
  • Remove whole spices and purée app

les using an immersion blender. Stir in vinegar. Pour into jars, cool and store in the fridge.

A few things that you never knew you could make in a slow cooker

Stock: the easiest way to get the most from leftover bones. Throw the bones in the slow cooker with some veg, a bay leaf and just cover with water. Leave cooking on low for 8 hours - or longer, if you’re after what’s now called bone broth, although there’s not much point than cooking for more than 24 hours. Strain and freeze or use immediately in soup, risotto or for adding an extra layer of goodness to a rice or grain dish.

Bread: seeing as we’re all experts at making bread now, here’s a new twist. Take your favourite simple white yeast bread recipe, knock it back after the first proving, shape it into a ball and place, on a sheet of greaseproof paper, into a slow cooker on high for 2 hours or until it is cooked through.

The loaf will be still rather palid so brown it in a 220C oven for 5-7 minutes and allow - if you can! - to cool before slicing and devouring.

Homemade dulce de leche: this rich caramel is the ultimate hands off recipe. Just take a full, unopened tin - or two - of condensed milk, submerge in water in the slow cooker, making sure that there’s at least 2cm of water above the tin, and cook at high for 8 hours. Make sure you allow the tin to cool before opening. Use in a banoffi pie, drizzled over pancakes or swirled into brownies before baking.

Christmas pudding: prep your Christmas treat without any fear of the pan boiling dry - I do so hate the smell of melted plastic pudding bowls. Steam the pud, with enough boiling water to come halfway up the sealed bowl, for 10 hours on high. To reheat on the big day, repeat the steaming for 4 hours on low, or until heated through.

Mulled apple juice: a slow cooker can both mull apple juice and keep it warm over a prolonged period of time for a delicious non-alcoholic tipple. Tip a bottle of your favourite local apple juice (The Apple Farm and Ballyhoura Apple Farm are both good) into the slow cooker pot, add 1 cinnamon stick, 3 cloves - or your favourite mulling spices - and a sliced orange. Heat on low for 3 hours and serve. Also works with cider or wine.
