When it comes to adding some green goodness to your soups, two popular choices often come to mind: kale and arugula. Both are nutrient-dense, delicious, and versatile, making them excellent additions to a variety of dishes. However, they have distinct differences in terms of taste, texture, and nutritional content. If you’re wondering whether you can use arugula instead of kale in soup, the answer is not a simple yes or no. It depends on several factors, including the type of soup, personal taste preferences, and the desired nutritional profile. In this article, we’ll delve into the world of kale and arugula, exploring their unique characteristics, uses, and potential substitutions in soups.
Understanding Kale and Arugula
Before we dive into the specifics of using arugula instead of kale in soup, it’s essential to understand the basics of these two leafy greens. Kale is a superfood that belongs to the Brassica family, which also includes cabbage, broccoli, and cauliflower. It’s known for its high nutritional value, including vitamins A, C, and K, as well as minerals like calcium and iron. Kale comes in several varieties, with curly-leaf, lacinato, and red Russian being some of the most common. Each type has its unique flavor profile and texture, ranging from mild and tender to bitter and chewy.
On the other hand, arugula is a peppery green that belongs to the same plant family as kale. It’s also known as rocket or roquette and is native to the Mediterranean region. Arugula has a distinctive, slightly bitter taste and a delicate, velvety texture. While it’s not as nutrient-dense as kale, arugula still packs a significant amount of vitamins A, C, and K, as well as minerals like calcium and iron.
Key Differences Between Kale and Arugula
When deciding whether to use arugula instead of kale in soup, it’s crucial to consider their differences in terms of:
- Taste and flavor profile: Kale has a milder, more earthy taste, while arugula has a peppery, slightly bitter flavor.
- Texture: Kale is generally chewier and more robust than arugula, which is delicate and tender.
- Nutritional content: Kale is higher in vitamins and minerals, particularly vitamins A and K, while arugula has a higher water content and lower calorie count.
- Cooking time: Kale typically requires longer cooking times to become tender, while arugula can be added towards the end of cooking time to preserve its texture and flavor.
Impact on Soup Flavor and Texture
The choice between kale and arugula can significantly impact the flavor and texture of your soup. If you’re looking for a heartier, more filling soup, kale might be the better choice. Its chewy texture and mild flavor make it an excellent addition to soups like minestrone, creamy broths, or stews. On the other hand, if you prefer a lighter, more refreshing soup, arugula could be the way to go. Its peppery flavor and delicate texture make it well-suited for soups like creamy tomato soup, chilled soups, or clear broths.
Substituting Arugula for Kale in Soup
Now that we’ve explored the differences between kale and arugula, let’s discuss the possibilities of substituting arugula for kale in soup. In general, arugula can be used as a substitute for kale in soups, but it’s essential to keep the following factors in mind:
- Adjust cooking time: Arugula has a shorter cooking time than kale, so add it towards the end of cooking time to prevent overcooking and bitterness.
- Balance flavors: Arugula’s peppery flavor can overpower other ingredients, so adjust the seasoning and spices accordingly to balance the flavor profile.
- Choose the right arugula variety: Baby arugula or wild arugula might be better suited for soups than mature arugula, which can be too bitter.
Some popular soups where arugula can be substituted for kale include:
- Creamy soups like potato soup or broccoli soup
- Chilled soups like gazpacho or cucumber soup
- Clear broths like chicken or vegetable soup
Optimizing Arugula in Soup
To make the most of arugula in your soup, consider the following tips:
- Add arugula in the last 5-10 minutes of cooking time to preserve its texture and flavor.
- Use a combination of arugula and other greens to create a balanced flavor profile and texture.
- Puree or blend arugula into the soup for a creamy, velvety texture and a deeper flavor.
Common Challenges and Solutions
When using arugula in soup, you might encounter some challenges, such as:
- Bitterness: Arugula’s peppery flavor can sometimes become bitter, especially if overcooked. To avoid this, add a squeeze of lemon juice or a splash of cream to balance the flavor.
- Texture: Arugula’s delicate texture can become mushy if overcooked. To preserve its texture, add it towards the end of cooking time or use it as a garnish.
By understanding the differences between kale and arugula and adjusting your cooking techniques accordingly, you can create delicious and nutritious soups that showcase the unique qualities of each green.

Will Arugula Change the Flavor of My Soup?
Arugula has a distinctive peppery flavor that can add depth and complexity to soups. If you’re used to using kale in your recipes, you may notice a difference in flavor when substituting with arugula. The peppery flavor of arugula can complement certain ingredients, like beans, vegetables, and lean proteins, but it may not be the best choice for every recipe. For example, if you’re making a creamy soup or one with delicate flavors, arugula may overpower the other ingredients. On the other hand, if you’re making a hearty, savory soup, arugula can be a great addition.
To minimize the impact of arugula’s flavor on your soup, you can start by using a small amount and adjusting to taste. You can also pair arugula with other ingredients that complement its flavor, such as garlic, ginger, or chili flakes. Additionally, consider the type of arugula you’re using, as some varieties may have a milder flavor than others. By experimenting with different recipes and flavor combinations, you can find the perfect balance of flavors to showcase the best of arugula in your soups.
Can I Use Arugula Stems in Soup?
Arugula stems are edible and can be used in soups, but they may require some extra preparation. Unlike kale stems, which can be tough and fibrous, arugula stems are typically more tender and can be used in a variety of dishes. To use arugula stems in soup, you can chop them finely and sauté them with other aromatics, like onions and garlic, to bring out their flavor. Alternatively, you can add them to the pot along with the other ingredients and let them simmer until they’re tender.
When using arugula stems in soup, keep in mind that they may add a slightly bitter flavor, which can be balanced by other ingredients. You can also use them in combination with other leafy greens, like spinach or collard greens, to create a hearty and nutritious soup. To get the most out of your arugula stems, be sure to chop them finely and cook them until they’re tender, as this will help to break down their cell walls and release their nutrients.
How Do I Prepare Arugula for Use in Soup?
To prepare arugula for use in soup, start by washing the leaves and stems thoroughly in cold water. Remove any tough or damaged leaves, and pat the arugula dry with a paper towel to remove excess moisture. Next, chop the arugula into the desired size, depending on the recipe and the texture you’re aiming for. For most soups, a rough chop or tear is sufficient, as the arugula will wilt and break down during cooking.
Once you’ve chopped the arugula, you can add it to your soup pot along with the other ingredients. If you’re using a particularly delicate recipe, you may want to add the arugula towards the end of the cooking time to prevent it from becoming too wilted. Alternatively, you can sauté the arugula with other aromatics, like garlic and onions, to bring out its flavor before adding it to the soup. By preparing your arugula properly, you can ensure that it adds the best possible flavor and texture to your soups.
Can I Use Frozen Arugula in Soup?
Frozen arugula can be a convenient and nutritious addition to soups, especially during the off-season when fresh arugula is not available. To use frozen arugula in soup, simply thaw it first by leaving it in room temperature or by thawing it in the refrigerator overnight. Once thawed, you can add the arugula to your soup pot along with the other ingredients, or you can sauté it with other aromatics to bring out its flavor.
When using frozen arugula in soup, keep in mind that it may have a softer texture and a less intense flavor than fresh arugula. However, it can still add plenty of nutrients and flavor to your soups. To get the most out of your frozen arugula, be sure to thaw it properly and squeeze out any excess moisture before adding it to your recipe. You can also use frozen arugula in combination with other leafy greens, like spinach or kale, to create a hearty and nutritious soup that’s packed with flavor and nutrients.
Are There Any Recipes Where Arugula is a Better Choice Than Kale?
While kale is a popular choice for many soups, there are certain recipes where arugula may be a better option. For example, if you’re making a light and refreshing soup, like a summer minestrone or a creamy broth, arugula’s delicate flavor and texture may be a better choice. Arugula is also a good option for soups where you want to add a peppery flavor, like a spicy black bean soup or a savory lentil stew.
In general, arugula is a good choice for recipes where you want to add a bright, fresh flavor and a delicate texture. It pairs well with ingredients like lemon, garlic, and cherry tomatoes, and can add a nice depth and complexity to soups. On the other hand, kale may be a better choice for heartier, more rustic soups, like stews and chowders, where its chewy texture and mild flavor can add body and substance. By choosing the right green for your recipe, you can create a delicious and satisfying soup that showcases the best of each ingredient.
