Enjoying Onions

Preparations of onions is rather simple. There are a few steps to take when doing so and some of them are the same regardless of what kind of dish you’re preparing and others need to be modified depending on what kind of dish you’re making.

Start by trimming the roots of the onions and then cut it in half. Peel of the outer brown layer of skin since it can’t be used in any way. Slice vertically and make sure you stop before the root so that it remains attached to the onion. Curl your fingers across the half of the onion and chop it next to your fingers.

Onions can then be used to be fried and prepared in a pan or added to a variety of different salads and quick and fresh meals. There’s nothing more you can do to prepare the onion other than add oils and other vegetable.

They can be kept in sacks as well and the key is for them to remain dry at all times.


There are countless recipes with onions and here are a few everyone can make.

-Preheat the oven to 200C/400F/gas mark 6. Rub the onions with a little olive oil (about 2 tbsp), then sprinkle with salt. Put the onions in a medium casserole or other ovenproof pot with a lid. Place the garlic head in the middle of the onions and drizzle with oil. Scatter the thyme sprigs over the onions, then add 75ml of the water to the pot. Cover and roast in the oven for 50-60 minutes, until the onions are lightly browned and soft enough so a knife slips easily into their centres. Set aside until cool enough to handle.

-Carefully lift the onions on to a cutting board, leaving the liquid in the pot. Scoop out a few layers from inside each onion and stuff them with 2 tbsp of sausage meat. Add the scooped-out onion to the casserole. (When you add the cream and water in the next step, the liquid should come a little less than halfway up the sides of the stuffed onions.)   Sign up for Word of Mouth: the best of Guardian Food every week.

– Squeeze the soft flesh of the garlic cloves into the casserole, and add the thyme leaves, cream, the remaining 225ml water and 1 tsp salt. Bring the mixture to a full boil, add the stuffed onions, sausage-side up, and baste them with the liquid for a minute or so.

4 Return the casserole to the oven for about 40 minutes, uncovered until the sauce is thick, but not gloopy. Baste the onions every 10 minutes or so, until cooked. Taste the sauce and add a little more salt, if you’d like. Bring the pan to the table, spoon a little of the sauce over the top of each onion, and dig in.
