What to pair onions with?
Onions can be paired with roast beef, roasted chicken, rice and stir-fries. They are a perfect addition to soups, stews, sauces, and casseroles. Onions can also be used to top pizzas or as a stuffing for mushrooms or bell peppers. Sautée onions with zucchini, tomatoes, eggplants and bell peppers for a ratatouille!

Preparing onions

Here are simple steps to prepare onions:
Peel the onion (using a sharp knife, cut off the root end and the top of the onion, remove the papery outer layer as well). Depending on the recipe, you may need to chop the onion into small pieces, slice it into thin strips, or dice it into medium-sized chunks.

  • For chopping, make vertical cuts from the top of the onion to the root end, without cutting all the way through. Then, make horizontal cuts in the onion, again without cutting all the way through. Finally, make downward cuts, chopping the onion into small pieces.
  • For slicing, cut the onion in half from root to top and then slice each half into thin strips. For dicing, make vertical and horizontal cuts as for chopping, but then turn the onion 90 degrees and make downward cuts.

Yellow Onions: These are the most common onions, with a golden-brown skin. They have a mild and sweet flavor that makes them ideal for soups, stews, and sauces.
Red Onions: Red onions have a crisp and slightly sweet flavor. They are best used raw in salads, sandwiches, or as a garnish for tacos and other Mexican dishes.
White Onions: White onions are sharp and pungent in taste. They are great for pickling or caramelizing and are often used in Mexican cuisine.
