How Much Does Kale Shrink When Cooked? – Guide

Hello! Are you interested in learning about how much kale shrinks when it’s cooked? This article will provide you with all the information you need to know about kale and its shrinkage during cooking.

Kale is a popular leafy green vegetable that is packed with nutrients and is often used in salads and smoothies. While it is most commonly eaten raw, it is also delicious when cooked. However, many people wonder how much kale will shrink when cooked, and if it will affect its nutritional value. In this article, we will explore this question in detail.

What is Kale?

Kale is a type of leafy green vegetable that belongs to the Brassica family, which also includes other nutrient-dense vegetables like broccoli, cauliflower, and Brussels sprouts. It is a popular and highly nutritious vegetable that has gained a lot of attention in recent years due to its impressive health benefits. Kale is an excellent source of vitamins A, C, and K, as well as calcium, potassium, and antioxidants. It is also low in calories and high in fiber, making it a great addition to any healthy diet.

Understanding Kale Shrinkage

Kale, like many other vegetables, experiences shrinkage when cooked. This is due to the release of water from the vegetable’s cells during the cooking process. When heat is applied to kale, the water inside its cells heats up and turns into steam, which then escapes from the vegetable. As a result, the kale becomes smaller in size and denser in texture. Understanding this process is important when it comes to cooking kale, as it can affect the overall texture and flavor of the dish.

How Much Does Kale Shrink When Cooked?

Kale, like most leafy greens, tends to shrink in size when cooked due to the loss of moisture. However, the extent of the shrinkage depends on a number of factors, such as the cooking method, the duration of cooking, and the size of the kale pieces.

In general, kale can shrink by about 50-75% of its raw size when cooked. For example, one cup of raw kale may reduce to about 1/2 to 1/4 cup when cooked.

When kale is cooked using dry-heat methods like roasting or baking, the shrinkage is more pronounced, as the heat causes the moisture in the leaves to evaporate quickly. On the other hand, when kale is cooked in liquid, such as in soups or stews, the shrinkage is not as significant, as the leaves absorb some of the liquid, which helps to retain their volume.

It’s also worth noting that the type of kale can also impact the degree of shrinkage. For example, curly kale may shrink more than flat-leafed kale varieties like Lacinato kale.

Overall, while kale may shrink in size when cooked, it still retains its nutritional value, making it a great addition to any meal.

Tips for Cooking Kale

Kale is a versatile leafy green that can be prepared in many ways, from raw in salads to cooked in soups or sautéed as a side dish. Here are some tips to help you cook kale while minimizing shrinkage:

  1. Choose fresh kale: Look for kale leaves that are fresh and vibrant in color. Avoid wilted, yellowed, or brown leaves, which are an indication of age or spoilage. Fresh kale will shrink less when cooked compared to older, wilted leaves.
  2. Remove the stems: The tough, fibrous stems in kale can be bitter and may take longer to cook. Remove the stems by holding the leaf upside down and running a sharp knife along the stem, separating it from the leaf. You can use the stems in soups or stews.
  3. Blanch kale before cooking: Blanching kale in boiling water for 2-3 minutes before cooking can help reduce shrinkage. Blanching helps to soften the kale leaves and removes some of the air pockets, allowing them to cook more evenly and shrink less.
  4. Use a high-sided pan: When sautéing kale, use a high-sided pan to allow the leaves to wilt without overcrowding the pan. Overcrowding can cause the kale to steam rather than sauté, resulting in more shrinkage.
  5. Cook kale briefly: Kale should be cooked until it is just tender, about 5-7 minutes, depending on the cooking method. Overcooking will cause the kale to shrink more and lose more of its nutritional value.

By following these tips, you can cook kale while minimizing shrinkage and retaining its flavor and nutritional value.


In conclusion, kale is a nutrient-rich vegetable that can be cooked in a variety of ways. It does experience some shrinkage when cooked, but the extent of the shrinkage will depend on the cooking method used. Overall, it is still a great addition to any diet due to its many health benefits. By following some tips for cooking kale and being mindful of the cooking method used, you can minimize shrinkage and retain as much of its nutritional value as possible. So, don’t be afraid to experiment with kale in your cooking and enjoy all the benefits it has to offer!
