Ingredients For Roasted Spring Onion With Tarragon Recipe
Spring onions: These are young onions with a mild flavor, perfect for roasting.
Olive oil: Adds richness and helps in caramelizing the onions.
Salt: Enhances the natural flavors of the ingredients.
Black pepper: Adds a touch of heat and depth.
Tarragon: A fresh herb that brings a unique, slightly anise-like flavor to the dish.
Technique Tip for This Recipe
When roasting spring onions, ensure they are evenly spaced on the baking sheet to allow for proper caramelization. This prevents steaming and ensures each onion develops a rich, golden-brown color. Additionally, tossing the onions halfway through the roasting process can promote even cooking and enhance their natural sweetness.

How To Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover roasted spring onions on a baking sheet. Cover them with aluminum foil to prevent them from drying out. Heat for about 10-15 minutes or until they are warmed through. This method helps maintain their caramelized texture and flavor.
Stovetop Method: Heat a non-stick skillet over medium heat. Add a small amount of olive oil or butter. Place the roasted spring onions in the skillet and cook for about 5-7 minutes, turning occasionally, until they are heated through. This method can add a slight crispiness to the onions.
Microwave Method: Place the roasted spring onions on a microwave-safe plate. Cover them with a damp paper towel to retain moisture. Microwave on medium power for 1-2 minutes, checking halfway through to ensure they are evenly heated. This is the quickest method but may result in a softer texture.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the roasted spring onions in the air fryer basket in a single layer. Heat for about 5 minutes, shaking the basket halfway through to ensure even heating. This method can help retain some of the original crispiness.
