How To Use Red Onion

Red onions are ideal for including raw in salads or in cooked dishes where a sweet onion flavour is required such as salsa, stuffed onions, chicken or fish dishes or mixed vegetable stews. They can also be used as a garnish or included in homemade chutneys to serve with cold meats and cheese.

How To Prepare Red Onion

Cut a thin slice from the top of the onion. Peel the skin away and remove any soft outer layers. Hold the onion by the root and slice or cut in half and chop into even-sized pieces.

How To Cook Red Onion

Onions can be fried, roasted or steamed. To fry, heat 1 tbsp olive oil in a pan, add the prepared onion and cook for 5 -10 minutes, stirring occasionally until tender. To roast preheat the oven to 200°C, gas mark 6. Add 2 tbsp olive oil to a roasting tin and heat in the oven, add the unpeeled onions, season well and roast for 45 - 55 minutes or until tender. To steam, place whole, peeled onions or sliced onions in a steamer. Cook whole onions for 40 - 50 minutes and sliced onions for 15 - 20 minutes.

How To Store Red Onion

Keep in a cool, dry place for 1 to 2 weeks.
