Maturity and Harvest Times
- Growing Time: Yellow onions grown from sets mature faster than those grown from seeds. Expect to see fully mature bulbs in about 90-100 days, depending on growing conditions.
- Signs of Readiness: When the tops start to yellow and fall over naturally, this is a sign the bulbs are reaching maturity. Once most tops have fallen, carefully lift the onions from the soil using a garden fork to avoid damage.
- Curing: To ensure proper storage, cure the onions by laying them out in a warm, dry, and well-ventilated area (such as a shaded porch or garage) for 1-2 weeks, allowing the outer skin to harden and the necks to dry thoroughly.
Cooking Applications
Yellow onions are a culinary staple for their slightly sweet, robust flavour that mellows with cooking. They’re incredibly versatile, working well in almost any recipe. Here are a few popular uses:
- Soups & Stews: Yellow onions provide the perfect savoury base for soups and stews, adding depth and sweetness as they caramelize.
- Roasting & Grilling: Roasting brings out the onion’s natural sugars, creating a slightly sweet flavour that pairs wonderfully with root vegetables or meats.
- Sautéing & Caramelizing: Yellow onions caramelize beautifully, making them perfect for French onion soup, sauces, or as a topping for burgers and steaks.
- Everyday Cooking: From stir-fries to casseroles and salads, yellow onions are your go-to choice for everyday recipes.
Ideal Storage Conditions
Properly cured yellow onions can be stored for up to 6-8 months, making them a fantastic option for long-term pantry staples. Here’s how to store them for maximum freshness:
- Temperature & Humidity: Store in a cool, dark, and dry place with temperatures around 1-4°C (34-40°F). Ideal locations include cellars or basements. Avoid storing onions in plastic bags, as this traps moisture and may lead to rot.
- Air Circulation: Onions need good airflow to stay fresh, so consider storing them in mesh bags, paper bags, or baskets to prevent any buildup of moisture.
- Avoid Proximity to Potatoes: Storing onions near potatoes can accelerate sprouting due to ethylene gas, so keep them separate for the best results.
