Flavor Profiles
The flavor of arugula is characterized by its peppery taste, which can add a distinctive, slightly spicy character to dishes. Spinach, on the other hand, is known for its more earthy taste and is less pronounced compared to arugula. This contrast in flavor is key when considering arugula as a substitute for spinach in salads.
Texture and Appearance
Textures between arugula and spinach also vary. Spinach leaves tend to be somewhat softer and can range from smooth to slightly crinkly, and when raw, provide a tender quality to salads. Arugula leaves are typically crunchier with a more robust texture, contributing a different mouthfeel to salads. Visually, spinach leaves are broader with a more oval or almond shape, while arugula leaves are longer, narrower, and often exhibit curly edges.
Preparing Arugula for Salads
When substituting arugula for spinach in salads, proper preparation is crucial to ensure its peppery flavor and crisp texture stand out. This section will guide you through effective methods for cleaning and storing arugula, as well as techniques for slicing that optimize its unique properties in salads.
Cleaning and Storage
Cleaning:
Place the arugula leaves in a large bowl of cold water to loosen any dirt or debris.
Gently swish the leaves around and then let them sit for a few minutes to allow the grit to settle to the bottom of the bowl.
Carefully lift the arugula out of the water and repeat the process if necessary, using clean water each time.
Once clean, use a salad spinner to remove excess moisture or pat dry with paper towels.
Storage:
After drying, wrap the arugula gently in paper towels to absorb any remaining moisture.
Store it in an airtight container or resealable plastic bag in the refrigerator's crisper drawer.
The arugula should remain fresh for 3 to 5 days; inspect leaves before use and remove any that have wilted.
Slicing Techniques for Arugula
Arugula's robust flavor and texture can be incorporated raw into salads, where its crunch provides a satisfying contrast to other ingredients. Here are two techniques for slicing arugula effectively:
Stack and Roll Cut:
Stack multiple arugula leaves on top of each other and roll them tightly like a cigar.
Slice the rolled leaves perpendicularly with a sharp knife to create thin ribbons that will distribute evenly in the salad.
Rough Chop:
For a more rustic look, simply bunch arugula leaves together.
Use a sharp knife to cut them into bite-sized pieces, aiming for similar sizes for uniformity in the salad.
In any salad, dressing arugula with a simple vinaigrette made of olive oil and lemon juice brings out its natural flavors. A sprinkle of salt can enhance its taste without overpowering it.
Substitution Tips and Techniques
When replacing spinach with arugula in recipes, one must consider the distinct peppery flavor that arugula offers. The substitution can bring a new depth to dishes, whether they are served raw or cooked.
Substituting Arugula in Raw Dishes
Arugula can be easily incorporated into raw dishes such as salads, where its bold taste can stand out. In raw preparations, one should:
Replace spinach with arugula in a 1:1 ratio in salads for a peppery kick.
Balance the bitterness with dressings that have a sweet or creamy component.
For instance, a vinaigrette made with balsamic vinegar and honey pairs nicely with arugula's spicy notes. For salads containing fruits or nuts, arugula complements these toppings well.
Using Arugula in Cooked Recipes
Arugula wilts more quickly than spinach when heated, but it can still substitute well in certain cooked dishes. Here's how:
Add arugula at the end of the cooking process to prevent over-wilting; it's perfect for stirring into pastas or topping on pizzas. (What wine goes well with pizza?)
Use a lighter hand or pair with other greens like kale or Swiss chard if substituting in quantity-heavy recipes like quiches (What wine goes well with quiche?) and soups where the volume is critical.
Arugula's flavor diminishes somewhat with cooking, which can be useful for those preferring a milder taste. One might consider using arugula with a bit of spinach or chard to balance the flavor profile in dishes like pesto or smoothies.
Salad Dressing Combinations
The right dressing can elevate an arugula salad, balancing its peppery flavor with complementary tastes. This section suggests optimal dressing pairings for arugula salads and provides recipes for homemade dressings that enhance the leaf's distinct characteristics.
Best Pairings for Arugula Salads
Arugula's bold taste pairs well with dressings that have a slight sweetness or acidity to them, which helps in balancing the peppery nature of the leaves. Here are some recommended combinations:
Balsamic Vinaigrette: The sweet and tart profile of balsamic vinegar complements arugula excellently.
Lemon Juice and Olive Oil: A simple dressing that uses the brightness of lemon to lift the salad.
Honey and Mustard: The sweetness of honey and the tang of mustard create a balanced taste with arugula's spice.
To add texture and contrast, consider adding nuts such as walnuts, almonds, pine nuts, or sunflower seeds, which introduce a satisfying crunch. Incorporation of fruit like sliced strawberries can introduce a sweet note that plays off the peppery greens. Additionally, cheeses such as feta or parmesan offer a salty counterpoint to the salad's fresh flavors.
Homemade Dressing Recipes
Creating a homemade dressing allows you to tailor flavors to your preference and is often healthier than store-bought versions. Here are quick recipes that marry well with arugula salads:
Simple Lemon Vinaigrette
3 parts olive oil
1 part fresh lemon juice
Salt and pepper to taste
Optional: a teaspoon of honey for sweetness
Whisk ingredients together until well combined. Drizzle over arugula and toss to coat evenly.
Sweet Balsamic Reduction
1 cup balsamic vinegar
2 tablespoons honey
Simmer balsamic vinegar in a saucepan until reduced by half and mix in honey until dissolved. Let cool and drizzle over the salad to add a rich, sweet element.
Whether opting for the tang of citrus or the depth of balsamic, these dressings enhance the peppery bite of arugula with delicious counterbalancing flavors.
Incorporating Arugula Beyond Salads
Arugula's peppery flavor makes it a versatile ingredient that can elevate the taste of various dishes, ranging from sandwiches to pizzas, and can even be used as a garnish or incorporated into sauces.
Arugula in Sandwiches and Pizzas
When it comes to sandwiches, arugula can replace traditional lettuce to add a zesty twist. Its robust flavor pairs well with cold cuts, cheese, and even grilled vegetables. For example:
A turkey and Swiss cheese sandwich may benefit from the sharp contrast of arugula, adding depth with its slightly bitter taste.
A Caprese sandwich transforms when fresh arugula is layered in, complementing the mild mozzarella and tangy tomatoes.
For pizzas, arugula serves as a fresh, flavorful topping often added after baking to preserve its texture and flavor:
A classic Margherita pizza (What wine goes well with margherita pizza?) gains complexity with a handful of fresh arugula leaves scattered on top just before serving.
A pizza with prosciutto and figs becomes a gourmet dish when finished with arugula, enhancing the sweet and savory profile.
Using Arugula as Garnish or in Sauces
Arugula can be more than just a salad green; it serves as an eye-catching garnish that adds both color and a flavor punch:
Boldly place whole or roughly chopped arugula leaves on top of grilled steaks or fish to introduce a fresh element to hearty plates.
Sprinkle a pinch of delicate arugula over soups or stews for a sharp flavor contrast and a pop of green.
In sauces, arugula can easily be blended to infuse its distinct taste:
Pureeing arugula into a pesto sauce, possibly mixed with basil, creates a vibrant and peppery alternative to the traditional recipe.
Finely chopping arugula and incorporating it into a salsa verde brings a spicy edge that complements grilled meats and vegetables.
Health Benefits of Arugula Over Spinach
When considering substituting arugula for spinach in salads, it’s important to note the unique health benefits arugula provides. This leafy green is not only low in calories but also rich in certain phytochemicals that can contribute positively to one's diet.
Comparison of Nutrient Profiles
Arugula, although similar to spinach in that it's a nutrient-dense leafy green, has its own distinctive nutrient profile. A 100g serving of arugula contains approximately:
Calories: 25

Dietary Impacts of Arugula
Arugula is a cruciferous vegetable, like broccoli and kale, which means it is high in fiber and beneficial phytochemicals. Its glucosinolate content stands out particularly as they break down into isothiocyanates. These compounds have shown promise in research for their role in helping protect against certain types of cancers. Moreover, arugula can be an excellent addition to a diet for those managing their weight due to its low calorie and high water content.
The protein content in arugula is also noteworthy for a leafy green, and while it isn't as high in protein as spinach, it can still contribute to the overall protein intake in a balanced diet. Fiber content in arugula supports digestive health, while its peppery flavor adds a unique dimension to dishes without the need for additional calories or sodium.
Common Questions and Concerns
When substituting arugula for spinach in salads, individuals may have questions about allergies, dietary restrictions, and how to keep the greens fresh. The following subsections provide specific information related to these common concerns.
Addressing Allergies and Dietary Restrictions
Arugula belongs to the Brassicaceae family, commonly known as the mustard family, which is different from spinach's Amaranth family. This distinction is crucial for individuals with allergies, as one may react differently to the two families. For those following strict dietary plans, it's essential to note that baby arugula might be a milder alternative potentially suitable for sensitive palates, similar in delicacy to baby kale, which is often more acceptable for various diets in the USA.
When considering substitutes for dietary reasons, one could look towards microgreens, which provide a diverse flavor profile and are less likely to cause adverse reactions. Microgreens are young vegetable greens that are approximately 1–3 inches tall. They have an intense aromatic flavor, concentrated nutrient content, and come in a variety of colors and textures.
Shelf Life and Freshness Tips
Arugula generally has a shorter shelf life compared to spinach, and thus, understanding how to store it properly can extend its usability. For optimum freshness, arugula should be stored in a refrigerator within a breathable container and with a damp paper towel to help maintain moisture without causing sogginess.
Storage Tip Description Refrigeration Store arugula in the vegetable crisper drawer at a temperature below 40°F (4°C). Humidity Control Keep the greens in a container with a damp paper towel to balance moisture levels. Prompt Use Use within a couple of days after purchase for best flavor and texture.
It is pertinent that consumers are aware that arugula, especially the tender baby arugula, may not last as long as spinach, often wilting after a few days. When shopping, individuals should seek arugula with vibrant green leaves and without any signs of yellowing, which can indicate deterioration.
