This article guides you through the basics of roasting spring onions, variations to suit every taste, tips for making the most of seasonal produce, and answers to common questions, all designed to inspire your springtime cooking.

Ingredients: What You’ll Need
Optional Additions

- Other herbs (dill, rosemary, or thyme)
- Scallions, leeks, or shallots for an onion trio
How To Roast Spring Onions: Step-by-Step Directions
- Preheat your oven to 350°F (or 375°F as some prefer for deeper caramelization).
- Prepare the onions: Trim the ends, remove tough outer layers, and slice in half lengthwise.
If bulbs are large, quarter them; if small, roast whole for best texture. - Arrange onions in a baking dish, cut sides down for even roasting.
- Sprinkle with fresh thyme leaves, salt, and freshly ground pepper.
- Dot with butter slivers, focusing on the bulb area for enhanced flavor.
- Roast for 35 minutes until onions are tender, browned, and caramelized.
Roasting time may vary (30–50 mins) depending on bulb size and oven temperature. - Transfer to a warm serving bowl and drizzle with any pan juices.
Optional: Squeeze fresh lemon juice over onions before serving.
