Frequently Asked Questions About Baby Purple Onion
What is the difference between a baby purple onion and a regular purple onion?
A baby purple onion is sold at a smaller size and may be harvested young; it is not necessarily a separate onion species. Its compact size makes it convenient to roast whole, pickle, or serve as a small garnish, while flavor varies by variety and growing conditions.
Can you eat a baby purple onion raw?
Yes, a baby purple onion can be eaten raw. Slice it thinly for salads, sandwiches, tacos, or burgers; if its bite is too sharp, soak the slices briefly in cold water and drain them before serving.
How should you store baby purple onions?
Store whole baby purple onions in a cool, dry, well-ventilated place away from sunlight. Keep them separate from damp produce, and refrigerate a cut onion in a sealed container, using it within a few days.
Are baby purple onions good for pickling?
Yes, baby purple onions are well suited to pickling because their small size makes them easy to leave whole or halve. Cover prepared onions with a vinegar-based brine and refrigerate; use a tested canning recipe if you want shelf-stable pickles.
Do baby purple onions make you cry when you cut them?
Yes, baby purple onions can make your eyes water when cut. A sharp knife, chilling the onion before slicing, and good ventilation can reduce exposure to the compounds that irritate the eyes.
Can you cook baby purple onions, or are they only eaten raw?
Baby purple onions can be cooked as well as eaten raw. Roast, grill, or sauté them to soften their texture and bring out sweetness; small onions can be cooked whole, though larger ones may need extra time.
Do you need to peel baby purple onions?
Yes, peel a baby purple onion before eating it. Remove the dry outer skin, rinse the onion under clean running water, and trim the ends with a clean knife.
Can you freeze baby purple onions?
Yes, you can freeze baby purple onions, but thawed onions become softer and are better for cooked dishes than fresh salads. Peel and chop them first, pack them airtight, and add them straight from the freezer to soups, sauces, or casseroles.
What can you make with baby purple onions?
Baby purple onions work in salads, relishes, skewers, and roasted vegetable dishes. Their small size also suits whole-onion roasting or grilling; pair them with hearty savory foods, or slice them into sandwiches for a crisp, sharp accent.
Can baby purple onions cause bloating or heartburn?
Yes, baby purple onions can cause gas, bloating, or heartburn in some people, and raw onion may be more bothersome. Try a smaller serving or eat it cooked, and avoid it if you know it triggers your symptoms.

What is Baby Purple Onion?
Baby purple onion is a small, purple-skinned onion, with the same familiar savoury character as larger onions. It can be eaten raw or cooked: slice it into salads and sandwiches, serve it alongside grilled food, or roast it whole until tender. In Turkey, small onions also work well in meze and pickles; elsewhere, they are an easy addition to everyday salads, tacos or burgers.
Raw, it is crisp and pleasantly sharp; cooking softens its bite and brings out a sweeter flavour. It provides fibre and purple plant pigments, while 100 g contains 40 calories. Pair it with fresh herbs and lemon for a bright salad, or roast it with just a little oil for a simple side.
