Roasting asparagus is a great way to enhance its natural aroma and sweetness. At 350 degrees Fahrenheit, asparagus should be roasted for 15-20 minutes, or until tender and slightly crisp. However, thicker asparagus spears may need 20-30 minutes. To prepare the asparagus for roasting, simply wash the spears, trim off the tough ends, and coat them with a seasoning mixture of olive oil, garlic, salt, and pepper.

What You'll Learn
Trimming asparagus
The first method is the bend-and-snap method. This involves holding the asparagus spear horizontally and bending it until it snaps. The asparagus will naturally snap where it starts to get tough. This method is simple and doesn't require a knife. However, it can result in the loss of too much edible asparagus, depending on the thickness of the stalk, how it is bent, and how fresh it is.
The second method is the slice method. This involves using a chef's knife to cut off the ends of the asparagus spears. Line up all the spears in a row and slice off the ends simultaneously, cutting right above where the stalks turn from white to green. This method ensures that you don't lose too much edible asparagus, but it requires a knife and a cutting board.
The third method is a combination of the first two methods, known as the snap-and-slice or snap-and-cut method. First, snap off the end of one asparagus spear to find where the woody part ends. Then, line up the rest of the spears and slice them at the same point. This method ensures that you remove the woody part of the asparagus while also keeping the spears a uniform length.
Regardless of the method you choose, it is important to wash the asparagus before trimming to remove any dirt or impurities. It is also a good idea to sort through the asparagus and remove any stalks that look shrivelled or dark, as these may not be fit for cooking.
Once you have trimmed your asparagus, you can cook it in a variety of ways, including roasting, sautéing, or grilling. Roasting asparagus, in particular, is a great way to bring out its flavour and create a delicious side dish.

Firstly, it is crucial to prepare the asparagus properly. This includes washing the spears and trimming the tough, woody ends, which can be unpleasant to chew. By removing these ends, you ensure a more enjoyable texture and even cooking. It is also recommended to pat the asparagus dry after washing to prevent excess moisture from causing steaming during the roasting process.
The next step is to coat the asparagus with a seasoning mixture. Typically, this involves drizzling olive oil over the spears and tossing them to ensure an even coat. You can also add other seasonings like garlic, salt, and pepper to enhance the flavour. The olive oil helps the asparagus achieve a delicious caramelisation during roasting.
Once the asparagus is prepared and seasoned, it's time to roast them in the oven. Place the seasoned spears on a baking sheet and put them in the preheated oven at 350 degrees Fahrenheit. The roasting time can vary depending on the thickness of the spears, but it typically ranges from 15 to 20 minutes for thinner asparagus and 20 to 30 minutes for thicker spears. It's important to keep an eye on the asparagus to avoid overcooking, as it should be tender yet still crisp when done.
Finally, when the asparagus is roasted to your desired level of doneness, remove it from the oven and transfer it to a serving platter. You can finish it with additional seasonings, such as a sprinkle of lemon zest or grated Parmigiano cheese, to add a burst of freshness or a cheesy element. It's best to serve roasted asparagus immediately to enjoy the optimal flavour and texture.

Roasting time
The roasting time for asparagus at 350 degrees Fahrenheit depends on the thickness of the spears. For thin asparagus spears, roasting takes around 15-20 minutes, while thicker spears may need 20-30 minutes. It is important to ensure that the asparagus is tender yet still crisp when roasted. Overcooking the asparagus can result in sogginess.
To achieve the desired level of doneness, it is recommended to pierce the asparagus with a fork. If the fork can easily pierce the asparagus without it becoming mushy, then it is ready. Aim for a vibrant green colour with slightly caramelised edges for the optimal flavour and texture.
Additionally, it is worth noting that the roasting time may vary depending on the desired level of browning. For a more browned and charred appearance, a hotter oven temperature, such as 425 degrees Fahrenheit, is recommended, which may reduce the roasting time to around 10 minutes.
To ensure even cooking and the best flavour and texture, it is advised to select fresh, vibrant asparagus with tightly closed tips and firm stems. Proper trimming of the tough ends is also crucial, and an even coating of seasoning is essential for enhancing the flavour in every bite. Arranging the asparagus in a single layer on the baking sheet allows for proper air circulation and even roasting.
