Frying Onions: A Quick And Easy Method

can you cook onions in a frying pan

Onions are a staple ingredient in many dishes, and cooking them in a frying pan can bring out their natural sweetness and a rich, deep flavour. The most common way to cook onions is to sauté them, which means frying them quickly over medium heat in a small amount of fat, such as olive oil or butter. Caramelizing onions is another popular method, where onions are cooked over low heat for an extended period, allowing their natural sugars to brown and give them a distinct colour, texture, and sweeter taste. Frying onions can be done in various ways, including pan-frying slices, deep-frying, and even microwaving, each resulting in different textures and flavours.

Caramelizing onions

First, peel and slice the onions. Aim for the slices to be as even as possible so that they cook at the same rate. You can cut them into long, thin slices, or cut the onion in half and make angled cuts into each half, aimed at the centre, without cutting all the way through.

Next, heat a stainless steel or cast-iron skillet on medium-high heat. Add butter and/or oil. For butter, a teaspoon per onion is sufficient, while for oil, two tablespoons for four onions is a good ratio. Once the butter has melted and the oil is shimmering, add the onion slices and stir to coat them evenly with the fat.

Spread the onions out in the pan and let them cook, stirring occasionally. Depending on your stovetop burner, you may need to reduce the heat to medium or medium-low to prevent the onions from burning or drying out. After 10 minutes, sprinkle some salt over the onions, and if desired, a teaspoon of sugar to help with caramelization. You can also add a little water to the pan to prevent the onions from drying out.

Let the onions cook for another 30 minutes to an hour, stirring every few minutes. You can let them stick a little to the pan to get some colour, but be sure to scrape the pan with a spatula to avoid burning. Once the onions are a rich, brown colour, you can add a splash of balsamic vinegar or wine to deglaze the pan and add some extra flavour.

Sautéing onions

Preparation:

First, peel the onion and slice it into thin slices. You can separate the slices into rings, or cut them into long, thin slices. A good technique is to sprinkle cornflour on the slices and toss them before frying, as this will give them an extra crisp texture without altering their flavour.

Choose your pan:

It is important to choose a pan that allows you to stir the onions easily while they are cooking. A large skillet or frying pan is a good option, and you can use stainless steel, cast iron, or non-stick varieties. Make sure the pan is warm before adding the onions, and that it is hot enough so that the onions do not steam instead of browning.

Cooking the onions:

Add oil or fat to the pan. Olive oil is a popular choice, but butter can also be used, or a combination of both. Heat the oil or butter over medium heat until it shimmers, then add the onion slices. Use a wooden spoon to spread them evenly in the pan. Sprinkle with a pinch of salt to draw out the liquid and encourage softening.

Stirring and browning:

Stir the onions frequently to prevent them from sticking to the pan and to ensure even cooking. The total cooking time will be around 10 minutes, and you should cook the onions until they are soft, golden, and browned in spots. It is important not to crank up the heat too high, as this can result in uneven results or burning.

Finishing touches:

Once the onions are softened and browned, they are ready to serve. Sautéed onions are often used as a topping for dishes such as burgers or pizzas, or added to sauces and stews. They can be stored in an airtight container in the fridge for up to four days and reheated in the microwave, or frozen for up to three months.

Sautéed onions are a delicious and versatile addition to many savoury dishes, and with these simple steps, you can easily incorporate them into your cooking.

Sweating onions

To sweat onions, heat up some oil in a pan to medium-low heat. Add the onions, season with salt and pepper, and stir or shake to prevent sticking or burning. The onions will get soft and then translucent. You can cover the onions with a cartouche to quicken the cooking process. Make a cartouche by folding a square of greaseproof paper in half into a triangle. Cut the triangle so that it is slightly larger than the width of your pan. Unfold the cartouche, crumple and dampen lightly with water. Place the cartouche on top of the onions with the lid on top and leave to sweat on a very low heat. After 10–15 minutes, the onions should be translucent and taste sweet.

If you want to cook onions until they are browned, this is called caramelising. Caramelised onions are cooked over a longer period, which allows them to release their natural sugars. This is what gives them their distinct colour, texture, and sweeter taste.

Frying onions in a microwave

Onions can be cooked in a frying pan to add a rich sweetness to almost any dish. They can be caramelized, sautéed, or fried. Caramelized onions are cooked over an extended period, allowing them to release their natural sugars, resulting in a distinct colour, texture, and sweeter taste. Sautéed onions take only a few minutes to cook and retain their sharp flavour. Fried onions, on the other hand, can be prepared with just onions and oil, sliced thinly and fried until golden brown.

However, frying onions in a pan can be tricky and may result in burning. An alternative method is to use a microwave, which requires less stirring and guesswork and produces consistent results. Here is a step-by-step guide to frying onions in a microwave:

Preparation:

First, slice the onions thinly and evenly. You can also cut them into long, thin slices. The key is to ensure that the onion slices are of uniform thickness.

Greasing:

Add oil to the sliced onions and grease them properly. You can also use butter instead of oil. Corn starch or corn flour can be added at this stage to give the onions an extra crisp texture.

Microwaving:

Spread the greased onion slices evenly in a microwave-safe bowl or plate. Place the bowl in the microwave and set the temperature to high. Microwave for 10 to 12 minutes, stirring the onions every 3 to 4 minutes to ensure even cooking. For one medium onion, a cooking time of 2 to 3 minutes is usually sufficient.

Cooling and Storage:

After microwaving, remove the onions from the microwave plate and place them on paper towels to absorb any excess oil and water. Allow the onions to cool completely before transferring them to an airtight container. Fried onions can be stored for up to 2 to 3 weeks and added to various dishes such as burgers, soups, salads, and pilafs.

Frying onions in the microwave is a convenient and mess-free way to achieve crispy and golden brown onions without the risk of burning. It is a safe and efficient method that produces consistent results every time.

Crispy fried onions

To make crispy fried onions, start by washing, peeling, and cutting the onions into evenly thin slices. The key to achieving the perfect crispiness is to ensure that the onion slices are of the same thickness. Once the onions are prepared, sprinkle corn flour on the slices and toss them to coat evenly. This step is optional but recommended for a crispier texture.

Next, heat oil in a deep pan until it is medium hot but not smoking. Be sure to use enough oil, as onions can get stuck to the pan if there is not enough oil or if the oil is not hot enough. Reduce the flame to medium, and add a few onion slices at a time to the pan, deep-frying them in batches. Fry the onions until they are golden brown and crispy, which should take around 2 to 4 minutes.

Once the onions are crispy, remove them from the oil and place them on a layer of paper towels to absorb any excess oil. You can then season the onions with salt and pepper to taste. Enjoy your crispy fried onions as a topping for casseroles, soups, salads, or any other dish you desire!
