What Is Asparagus?

Asparagus is a green vegetable that belongs to the lily family. It is native to Europe but now widely cultivated around the world. Asparagus grows best in cool climates during the spring season, when it produces tender and succulent shoots that are rich in vitamins and minerals.

Factors Affecting Cooking Time

The cooking time of asparagus depends on several factors, including:

  • Thickness: Thicker asparagus spears will require more time to cook than thinner ones.

5 Tips For Cooking Asparagus

Here are some tips for achieving perfect roasted asparagus every time:

  • Preheat your oven – Before you start roasting your vegetables, preheat your oven at 400°F (205°C) for 10-15 minutes. This ensures that your veggies will cook evenly while preventing them from becoming soggy or overcooked.
  • Choose the right baking sheet – Use a rimmed baking sheet for roasting your vegetables instead of a flat one because rimmed ones prevent any olive oil from spilling over the edges of the tray.
  • Drizzle olive oil evenly – Spread out your asparagus spears in a single layer and drizzle them with olive oil, turning them to make sure they are evenly coated.
  • Season with salt and pepper – Sprinkle your asparagus with salt and pepper or any other desired seasoning.
