Yellow Onion: Good all-around, general use onion. Good for Caramelizing, and just about any onion need.

Sweet Onions (Vidalia): A particularly mild version of a yellow onion, grown around Vidalia, Georgia. Crunchy and sweet! Walla Walla is another brand of sweet onion, grown in Washington, USA. Can be eaten like an apple tbh. REALLY GOOD for people who are sensitive to the strong flavor of onion.

White Onion: A little sweeter and milder than the yellow onion, but not as sweet as a sweet onion. Good for dicing and serving raw if you don't have red onion. Yellow and White onions are pretty much interchangeable.

Red Onion: Great Raw! Have a bit of spice to them, and make a very interesting savory flavor when cooked. (Red onion skins can be made into a dye!)

Green Onions/Scallions: Immature onions with white bottoms and green tops. Usually diced/sliced and used raw as a garnish or a mild raw onion flavor. Can be used to replace raw onion in bulk for a milder alternative.

Chives: Tinier, punchier alternative to green onions/scallions. While in the same Allium family as the rest of these, they never get bigger than their little grassy figure. Teeeeny tiny! Great for adorable garnishes and just a hint of onion in a salad. Not good for cooking with, they get bitter fast.

Shallots: Garlicky! Kinda a halfway point between 'onion' and 'garlic'. They stay small when fully matured, and have quite a bite when used raw. Cooked, they become mellow and have a less-intense garlic-onion flavor. Often used in sauces where you want a little onion and garlic flavor, but subtly. They're REALLY good roasted.

Leek: Basically like a giant green onion, except they're always like that. Can be used in place of Onion in nearly any recipe that doesn't require caramelization. Fun slice shape! Gentle onion flavor without a lot of bite. Best when cooked, not raw imo.
