Leeks are delicious, versatile vegetables. If you are unfamiliar with leeks or simply want to know more about these amazing veggies, you’re in the right place!
Read on to learn all about leeks, how leeks taste, how to select them, store them, and prepare them for cooking. We’ll also give you suggestions for how to incorporate leeks in a variety of dishes.
What are leeks?
Leeks are a vegetable in the onion family. More broadly, they are an allium, which is a family of vegetables that also includes scallions, onions, chives, and garlic.
What do leeks look like?
Leeks look like oversized green onions. They are tall vegetables that start out as narrow white bulbs at the bottom of the plant near the root, transition to light green stalks, and fan out slightly into flat, dark green leaves at the top. Leeks vary in size from small to large—typically around 12-16 inches long with 1-2 inch diameter stalks, but can grow to 2-3 feet in length.
Are leeks good for you?
Leeks are nutritious vegetables with several health benefits. They are low in calories and carbs and are a good source of many nutrients, including vitamins A, C, and K as well as calcium, magnesium, potassium, and iron.
Leeks are also a good source of antioxidants, particularly flavonoids, which may help reduce the risk of chronic disease. Additionally, leeks are a good source of dietary fiber, which can help keep the digestive system healthy. Read more about their health benefits here.
What do leeks taste like?
Leeks are mild-flavored vegetables that taste similar to an onion, but sweeter with much less intensity. Their taste can vary depending on how they are prepared. Raw leeks are crisp with a slightly sweet taste and subtle earthy undertones whereas cooked leeks taste sweeter and more mellow, with a texture that is similar to cooked onions. A leek’s size also impacts its flavor—smaller leeks tend to have a milder taste than larger, older ones.
What part of the leek do you eat?
The white and light green parts are the most tender and have the best flavor. The dark green leaves of leeks can be eaten as well, but are a little tougher and more fibrous than the lighter parts, plus they can be bitter, so they are often discarded. However, many people chop them up and add them to soups or stews for added flavor, or use them to make homemade vegetable stock.
Can you eat leeks raw?
Yes, you can eat leeks raw. Raw leeks have a crisp texture and a slightly sweet flavor, similar to onion but milder. They can be sliced thin and added to salads or diced and used as a topping for soups or baked potatoes.
What do cooked leeks taste like?
Cooked leeks have a sweet and mellow flavor, making them a great addition to many dishes. When cooked, leeks are tender and have a slightly creamy, almost buttery texture. If you’re looking for a vegetable that will add flavor without overwhelming other ingredients, leeks are a great option.
Are leeks strong in flavor?
No, leeks are typically not strong in flavor. They have a mild taste that is similar to an onion, but sweeter. Smaller leeks tend to have a milder taste than larger leeks.
Leeks vs. Green Onions
Leeks and green onions are both members of the Allium family, which also includes garlic and shallots. They look similar, but a leek is much larger than a green onion, with thicker stalks and leaves.
As far as flavor, green onions are much stronger, with a sharp, almost fiery taste. In contrast, leeks taste milder with a hint of sweetness.
You can substitute leeks for green onions in most recipes, but keep in mind that using leeks will result in a much milder flavor.
How do you select leeks?
When selecting leeks, choose those that have firm white bulbs and stalks, and dark green leaves. Look for leeks that are crisp and brightly colored and avoid leeks that have any signs of wilting, bruising, browning, or yellowing.
How do you store leeks?
Leeks can be stored in the refrigerator for up to 2 weeks, depending on how fresh they are when purchased. It’s best to avoid trimming or washing leeks before storage. Simply seal them in a plastic bag or wrap them in plastic wrap and store them in the crisper drawer until ready to use.
Can you freeze leeks?
Yes, you can! Though fresh leeks are always the best option for cooking, freezing leeks will allow you to enjoy their flavor and texture year-round. Here’s how:
First, wash the leeks thoroughly to remove any dirt or sand. Next, cut off the root end and the dark green parts. Slice the leeks into thin rounds or chop them into small pieces, depending on how you plan to use them. Finally, spread the leeks in a single layer on a baking sheet and freeze them until solid.
Once frozen, transfer the leeks to a freezer-safe container or bag and they will keep for several months. When you are ready to use them, no need to thaw them before adding them to a recipe.
Because of the way leeks grow in sandy soil, they often have sand and dirt trapped in their many layers. For this reason, it is important to clean leeks thoroughly before cooking with them.
First, cut off the root end and the dark green leaves. Then, halve the leek lengthwise. From there, you can clean them using any of the following methods:
- Rinse each half under cold running water, fanning the layers to make sure you are thoroughly washing away any dirt or sand that may be hiding inside.
- Cut the leek into pieces (see below for a variety of ways to do this) and place in a colander. Rinse with cold water until clean.
- Cut the leek however you’d like and place the pieces in a bowl of cold water. Stir around a bit and then let sit for a few mins—the dirt and sand will sink to the bottom. Remove the leek pieces from the bowl and dry with a paper towel before using.
How to cut leeks
Cutting leeks is a simple process. Trim off the dark green tops and root end, leaving the stalk. You can save the leaves for use in vegetable stock or other dishes, or compost them.
Once the stalks are cut, you can chop them further depending on how you plan to use them. Here are a few ways:
Cut in half lengthwise
Simply slice the leek stalk in half on the long side. Leek halves are great for roasting, but they can also be grilled, boiled, or steamed.
Slice them into rounds
For this option, don’t cut the stalk in half—rather, start at one end of the cylinder and slice small circles. You can slice them very thinly for salad toppings, or thicker for sautéing or adding to soups or other dishes.
Cut them into half-moon shapes
Cut the leek in half lengthwise. Place each half flat side down and slice thinly. Thin half-moon slices are great raw as salad or baked potato toppings, but can also be added to soups or other cooked dishes.
Cut them into small pieces
Cut the leeks in half lengthwise, place flat side down, and cut into 2-3 inch pieces. You can add these to soups, or pan-fry, boil, braise, or steam them.
Slice them into thin strips
Cut the leek in half on the long side, then continue to slice lengthwise in small sections. This variation works great in stir-fries or sautéed as a side dish on its own.
Whichever way you decide to cut your leeks, make sure to thoroughly clean them before using.
Cooking with Leeks
Leeks are a wonderful addition to many dishes, adding both flavor and nutrition. They tend to take on the flavors of whatever they are cooked with, making them a versatile ingredient. They can be used in soups, stews, or other dishes, or simply sautéed and served as a side dish. Leeks are also a good alternative for those who don’t like the strong taste of onions, as they provide a milder flavor while offering a similar texture.
How to Cook Leeks
The easiest and quickest way to prepare leeks is to sauté them. Heat some olive oil or butter in a pan over medium heat and add chopped leeks. Cook for 5-7 minutes, stirring occasionally until they are softened.
Roasted leeks are also a great option. Place leek halves or pieces on a baking pan, drizzle with olive oil, and sprinkle with salt and pepper. Roast them at 425°F for about 20 minutes. You may need to shorten the cooking time for smaller pieces to avoid overcooking.
They can also be grilled, boiled, steamed, or braised.
Whichever method you use, make sure to keep an eye on the leeks while cooking. Do not overcook, otherwise, their texture will turn mushy rather than tender.
What to Make With Leeks
Leeks are a wonderful way to add flavor and depth to a variety of dishes. Here are some ideas for using leeks in your cooking:
One of the most popular ways to use leeks is in soup, often as the main ingredient (leek soup), but also as a complementary one. Leeks can be added to soups for extra flavor and nutrition—as rounds or half-moons, or larger chunks if you prefer. They add a delicious, mild flavor and are a good substitute for onions in many recipes.
Leeks are a particularly good choice for vegetarian soups (potato leek soup is a popular option), but can also be used in chicken or beef soups. You can also use the dark green parts of leeks to make homemade stock.
Leeks are a great addition to stir fry dishes, adding a mild onion flavor and crunchy texture. We like to add them as thin strips to maintain firmness and help avoid overcooking, but you can also add them in smaller pieces for a more tender taste and texture.
If you’re looking for a great way to switch up a classic stuffing recipe, swap onions for leeks. They will provide a slightly different flavor profile with a hint of sweetness.
Leeks are a great addition to risottos, adding both flavor and a bit of substance. They can be cooked with the rice, or mixed in after the main dish is done.
Leeks pair well with eggs and can be used in many different ways: sautéed and served as a side dish, added to omelets or scrambled eggs, or used in quiches or frittatas.
Leeks can add a delicate flavor and beautiful color to any pasta dish. They are also a great way to boost the nutritional value of pasta dishes without adding a lot of calories or carbs.
Leeks add a delicious flavor and a bit of crunch to pizza. Top cooked pizza with freshly sliced leeks, or add to your pizza before baking. Use roasted leeks for added flavor.
