How to Chop an Onion – into slices

If you haven’t already, please make sure you’re familiar with basic knife safety before starting this tutorial. (link) Please remember to give onions special consideration because of their shape, texture, and tendency to make your eyes water!

The chunks of onion from our previous tutorial (link) are great for slow-cooking, but if you want fried onions then I like slices best.

Just like before, we want to take off the skin, top and bottom from the onion. You can start in the exact same way – chop off the root and the top of the onion, making sure to keep your fingers out of the way.

(For slices, you might actually want to leave the root end on for now – try it both ways and see which you prefer!)

 

 

Once you have a flat surface at one end of the ball, you can rest it there to cut downwards, slicing your onion in half. Then deal with each half in turn, starting with a cut right down the middle.

When you’re chopping onions, it’s a lot easier and quicker to work with if all the layers stay stuck together. So, when you’re slicing, work from the thin end(s) into the middle. And if you need to turn the onion around to get to the other end with your dominant hand, try turning the chopping board instead.

Although very thin slices of onion are so impressive (I’ve always loved watching chefs cut off super thin slices at top speed!), slices about half a centimeter (1/4 of an inch) thick are great for everyday cooking.

 

 

 

 

These onion slices take about 15-25 minutes to fry, although it depends how soft you like your onions! Onions can be eaten raw, or very well-done, so it’s really a matter of taste. They’re a great accompaniment to fried meats like sausages or burgers, or (my personal favourite) fish. And they’re a great source of flavour in a stir-fry, which we’re working towards this month!

How to Make Pot Roast Vegetables

Whether you’re making Sunday lunch, Christmas dinner, or just a warm winter treat, pot roast vegetables are melt-in-the-mouth delicious!

You will need:

  • a sharp knife
  • a chopping board
  • an oven-proof dish
  • an oven
  • oven gloves

and the ingredients (for four people):

  • 4 medium carrots (about the length of your hand)
  • 2 medium onions
  • 4 potatoes (about the size of your fist)
  • ½ large or 1 small swede
  • 1 large or 2 small sweet potatoes
  • 1-2 parsnips
  • dried mixed herbs
  • salt
  • oil

 

Start by turning on your oven to Gas Mark 4, 180° (160° fan).

Chop your carrots, onions, potatoes, and swede into chunks. (You can find more detailed instructions here: carrots, onions, potatoes, swede)

Put your chopped vegetables into your oven-proof dish.

Add salt, oil, and herbs to the dish. You just need to cover the vegetables in the dish, like in the picture below.

Place the lid on your dish and put it into the oven. It will take about two hours to cook from here.

Chop your sweet potato and parsnip into chunks. (More detailed instructions here: sweet potato, parsnip)

After your dish has been cooking for about an hour, add your sweet potato and parsnip chunks. Give your veggies another good stir or shake together, but be careful – it’s hot!

After another hour in the oven, your dish will be ready to serve! Serve it alongside whatever source of protein you fancy – it goes fantastically with a huge range of meat and veggie options!

You can roast a huge variety of vegetables, this recipe is just the start! Feel free to play with the seasonings too – try adding pepper, or using sage, rosemary and thyme instead of a pre-made mix of dried herbs.

How to Make Sausage Casserole

Casserole is one of my favourite winter dishes. It does take a couple of hours in the oven, but it doesn’t take much preparation. This is a good, basic recipe to get you started with casseroles.

You will need:

  • a sharp knife
  • a chopping board
  • an oven-proof dish
  • a measuring jug
  • a kettle
  • an oven
  • oven gloves

and the ingredients (for four people):

  • 4 medium carrots (about the length of your hand)
  • 2 medium onions
  • 4 potatoes (about the size of your fist)
  • 1 large or 2 small sweet potatoes
  • 8 sausages (meat or vegetarian)
  • stock cube
  • frozen peas (I like petits pois)

 

Start by turning on your oven to Gas Mark 4, 180° (160° fan).

Chop your carrots, onions, and potatoes into chunks. (You can find more detailed instructions here: carrots, onions, potatoes)

Boil the kettle and make up about half a litre of stock. Different stock cubes vary, so make sure to read the instructions!

Put your chopped vegetables, and meat sausages if you’re using them, into your oven-proof dish. Pour in the stock. Your vegetables and sausages should be more or less covered by the liquid. If they’re not, add a little more hot water from the kettle.

Place the lid on your dish and put it into the oven. It will take about two hours to cook from here. Because of all the liquid, casserole is unlikely to burn. It’s best to stay where you can smell it, but you don’t need to watch it the whole time.

Chop your sweet potato into chunks. (More detailed instructions here: sweet potato)

After your dish has been cooking for about an hour, add your sweet potato chunks.  If you’re using vegetarian sausages add these too. You can stir everything together if you want, but be careful – it’s hot!

About five minutes before you want to serve your dish, take it out of the oven and stir in the frozen peas. The peas will cook from the heat in the dish, and then you’re ready to serve!

Sausage casserole is a complete meal by itself, but it also goes great with a nice brown bread to soak up all the gravy!

You can create a lot of yummy variations on a good sausage casserole. You can add all sorts of different root vegetables, herbs such as sage or rosemary, and spices such as paprika. You might also want to add salt – I haven’t included any in this recipe because the stock and sausages can be salty enough by themselves.

How to Chop an Onion – into chunks

If you haven’t already, please make sure you’re familiar with basic knife safety before starting this tutorial. (link)

Onions are full of flavour, which gets sweeter the longer you cook them. The chunks we’ll be chopping today are perfect for long, slow, cooking that brings out all the best in onions.

Onions can be a little tricky to chop, because of their round shape and smooth skin. I would recommend using a serrated knife to chop onions; if you prefer to use a smooth knife I would start each cut by piercing the onion with the tip of your blade.

Unlike carrots and potatoes, we don’t want to eat the skin of the onion. These dry, papery layers are best peeled off and discarded, and you can pull off any little rootlets from the bottom of the onion too. You might find that this is easier to do after you’ve started cutting the onion; as long as you take off the skin before cooking it doesn’t really matter!

The first two cuts are the trickiest – we want to chop the top and bottom off the onion. Make sure to hold the onion firmly on its side, but keep your fingers out the way!

You should now have a flat surface at the bottom of the ‘ball’, which you can rest the onion on to make the rest of the cutting safer. For these chunks, simply chop the onion in half straight down the middle. Cut each half in half again, then into quarters, and you’re done!

 

 

 

When you’re chopping or cooking onions, you might find that your eyes start to sting, burn, or well up. This is because sulphur-containing compounds that give onions a lot of their flavour can react with the water in your eyes to make sulphuric acid. If it becomes hard to see, it’s important that you don’t try and keep cooking – you’re likely to hurt yourself. You might find that washing your hands, knife or onion under clean water can help your eyes sting less; just make sure to pat everything dry before you go back to chopping.

 

These onion chunks are perfect for roasts, casseroles, and stews. They take about 2 hours to cook in an oven at Gas Mark 4 (180°C, 160°C in a fan oven). Once they’re cooked, onions become soft and the layers fall apart easily.
