To make roasted baby onions, peel and dry them, toss with a little oil and seasoning, then roast until tender and browned. Spread them in a single layer so they roast evenly rather than steam.
You can roast baby onions with their skins on, which helps keep them from drying out. Once they are cool enough to handle, slip off the skins; peel them before roasting if you want the seasoning to coat the onions directly.
Roasted baby onions usually take around 25–35 minutes in an oven at about 400°F (200°C), depending on their size and your oven. Turn them once and remove them when tender and lightly browned.
Roasted baby onions pair well with roast chicken, grilled meat, fish, and other roasted vegetables. You can also add them to grain bowls, salads, pasta, or stews for a sweet, savory onion flavor.
Baby onions and pearl onions are closely related small onions, but the names can describe different varieties and sizes. Recipes often use them interchangeably; choose onions of similar size so they cook at the same rate.
Roasted baby onions taste sweet because heat concentrates their natural sugars and creates browned, caramel-like flavors. Roast them until golden rather than deeply charred, since burning can make their sweetness turn bitter.
Yes, you can roast baby onions unpeeled and remove their skins after cooking. The skins protect the flesh from drying, but they are not pleasant to eat, so peel the onions before serving.
Store leftover roasted baby onions in a covered container in the refrigerator and use them within about 3–4 days. Let them cool promptly after cooking, and reheat only the portion you plan to eat.
Yes, roasted baby onions can be frozen, though they may be softer after thawing. Cool them completely, pack them airtight, and use the thawed onions in soups, sauces, or other cooked dishes.
Roasted baby onions become burnt or bitter when they cook too long, at excessive heat, or in a crowded pan that roasts unevenly. Spread them out, turn them during cooking, and take them out once tender and golden.

Roasted baby onions are small onions cooked until tender and lightly browned. Roasting softens their sharpness and brings out a gentle sweetness, with a tender centre and lightly caramelised edges.
They work as a warm side for meat, fish or roasted vegetables, and can also be folded into salads, grain bowls or an antipasto-style spread. They are low in calories and provide some fibre: a 100 g portion has 44 calories. Pair them with beans or whole grains for a more filling meal, or use them to add sweetness and texture to a simple salad.
Medium
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
