Collapse ▲April is peak asparagus season! It’s also one of the first spring vegetables to be ready for harvest. Asparagus is crisp and tender when cooked and is easy to grill at family cookouts thanks to its long and sturdy shape. Generally, thinner spears are more delicate and tender; thicker spears have stronger flavor and hearty texture. Thicker spears can be sliced on the diagonal into smaller pieces to cook more quickly. This popular vegetable comes in green, white, and purple colors. Green – the most common type. White – covered with soil as it grows to keep green pigments from developing. Considered a delicacy and may cost more than green. Purple – has more sugar and less fiber than green. The skin is burgundy or purple but the flesh is pale green to creamy white. Cooking may cause more green color to show. Less commonly available and may cost more than green. Asparagus benefits include its low caloric value and its high vitamin, mineral, and antioxidant content. Asparagus is a great source of fiber, vitamin K, and folate! Fiber is beneficial to gut health and may help lower blood cholesterol. Vitamin K assists in blood clotting, which helps us heal from cuts and wounds. Folate helps in making new cells in our bodies, which is why it’s so important during pregnancy. Just half a cup of cooked asparagus contains

For fresh asparagus, choose bunches with stalks that are bright green or purple-tinged with firm stems. Avoid limp or wilted stalks. Thicker stalks have a stronger asparagus flavor while thin stems are more tender and sweeter. When looking at the spearhead, look for heads that are tight, like on the left side of the photo, and not “ferned out”. Refrigerate asparagus for up to four days by wrapping ends of stalks in wet paper towel and placing in plastic bag. Asparagus can be enjoyed raw or cooked, and it’s often a star ingredient in soups, stews, salads, and other dishes. Asparagus cooks quickly. Cook it until just barely tender. Thicker stalks take longer to cook. Overcooked or reheated cooked asparagus may become bitter and stringy or mushy.
❁ Boil or blanch in enough water to cover the stalks.
❁ Steam over boiling water.
❁ Sauté or stir-fry in a small amount of oil or fat.
❁ Roast or grill until lightly browned.
