Ready to dive into the leafy showdown of arugula vs watercress? Let’s explore these verdant virtuosos and discover which one might become your new favorite green.
Appearance and Taste
At first glance, arugula and watercress might seem like distant cousins in the leafy green family. Arugula boasts elongated, lobed leaves with a delicate, feathery appearance. Its color ranges from pale green to deep, forest hues, depending on its maturity.
Watercress, in contrast, sports small, round leaves clustered on thin, crisp stems. Its vibrant green color is often tinged with a hint of blue, giving it a distinctive look.
But it’s in the flavor department where these greens truly shine. Arugula packs a peppery punch that can range from mild to downright spicy. Its complex flavor profile includes notes of nuttiness and a subtle earthiness that lingers on the palate.
Watercress, not to be outdone, offers a crisp, refreshing bite with a peppery kick of its own. Its flavor is often described as slightly bitter and tangy, with a clean, almost aquatic finish that speaks to its semi-aquatic growing conditions.
Both greens add a zesty zing to dishes, but arugula tends to be more versatile in its intensity. Watercress, with its bolder flavor, often takes center stage in the dishes it graces.
Nutritional Powerhouses
Calorie and Macronutrient Content
When it comes to watching your waistline, both arugula and watercress are your allies. These greens are incredibly low in calories, making them perfect for bulking up meals without adding extra pounds.
Arugula clocks in at a mere 5 calories per cup, while watercress is even lighter at just 4 calories. Both are virtually fat-free, but don’t let that fool you – they’re packed with goodness.
Protein content is surprisingly decent for leafy greens. Arugula offers about 0.5 grams per cup, while watercress edges ahead with 0.8 grams. It’s not steak, but it all adds up!
Carbohydrates are minimal in both, with fiber being the star player. This fiber content aids digestion and helps keep you feeling full longer.
Vitamins and Minerals
Arugula and watercress are veritable vitamin mines. Both are loaded with Vitamin K, essential for blood clotting and bone health. Arugula takes the lead in folate content, crucial for cell growth and DNA formation.
Watercress, however, is the undisputed champion of Vitamin C, packing more of this immune-boosting nutrient than an orange, ounce for ounce. It’s also a rich source of calcium, outperforming many dairy products.

Culinary Uses
Raw Preparations
Arugula and watercress shine brightest in their raw form, adding a peppery punch and crisp texture to a variety of dishes.
In salads, arugula’s versatility is unmatched. It can stand alone as the base for a simple salad or mix beautifully with other greens. Try it with sliced pears, goat cheese, and a balsamic vinaigrette for a classic combination.
Watercress makes for a more assertive salad base. Its bold flavor pairs well with creamy dressings and robust ingredients like blue cheese or crispy bacon. A watercress and orange salad with a citrus vinaigrette is a refreshing treat.
Both greens make excellent additions to sandwiches and wraps. Arugula adds a gourmet touch to a simple turkey sandwich, while watercress can elevate a humble egg salad to new heights.
As garnishes, these greens are unbeatable. A handful of arugula can transform a plain pizza into a gourmet experience. Watercress makes a beautiful and flavorful topping for soups, adding a pop of color and a fresh, peppery note.
Cooked Applications
While often enjoyed raw, both arugula and watercress can be cooked to great effect, though their flavors mellow significantly with heat.
Arugula wilts beautifully when added to pasta dishes at the last minute. It’s also fantastic in omelets or frittatas, adding a subtle peppery note to egg dishes.
Watercress can be used similarly to spinach in cooked dishes. It’s delicious in stir-fries, soups, and even as a pizza topping. A classic watercress soup is a comforting and nutritious meal.
Both greens can be quickly sautéed with garlic and olive oil for a simple side dish. Remember, they cook down significantly, so use more than you think you’ll need.
Cooking does diminish some of the nutritional content, particularly vitamin C. However, it can make other nutrients more bioavailable, so don’t shy away from cooking these versatile greens.
Flavor Pairings
Arugula’s peppery, slightly nutty flavor pairs beautifully with a wide range of ingredients. It’s a natural match for:
- Citrus fruits (especially lemon and orange)
- Soft, creamy cheeses like goat cheese or burrata
- Nuts (particularly walnuts and pine nuts)
- Balsamic vinegar
- Prosciutto or other cured meats
Watercress, with its more assertive flavor, works well with:
- Eggs (in all forms)
- Smoked fish (especially salmon)
- Apples and pears
- Blue cheese
- Beef (try it in place of horseradish)
Both greens pair well with garlic, olive oil, and Parmesan cheese – the holy trinity of many Italian dishes.
For a unique twist, try arugula in a fruit smoothie for a peppery kick, or use watercress as a base for a zesty pesto. The possibilities are endless with these flavorful greens!
Practical Considerations
Buying and Storage
When selecting arugula, look for crisp, vibrant green leaves without any signs of wilting or yellowing. Avoid bunches with slimy or mushy leaves, as these are past their prime.
For watercress, seek out bunches with firm, dark green leaves and crisp stems. Avoid any that look yellowed or have slimy stems.
To keep your greens fresh, store them in the refrigerator. Wrap arugula loosely in paper towels and place it in a plastic bag. It should last about 5-7 days.
Watercress is a bit more delicate. Store it stem-down in a glass of water, like a bouquet of flowers, and cover the leaves loosely with a plastic bag. Change the water daily, and it should stay fresh for 3-5 days.
For both greens, wait to wash them until just before use to prevent excess moisture, which can lead to faster spoilage.
Serving Sizes
A typical serving size for both arugula and watercress is about 1 cup (loosely packed) for raw applications. This amount provides a good nutritional boost without overwhelming other ingredients in a dish.
For cooked applications, you might want to start with 2-3 cups raw, as these greens cook down significantly.
Incorporating these greens into your diet is easy. Add a handful to your morning smoothie, use them as a bed for grilled chicken or fish, or simply toss them into your regular salad mix.
Remember, while these greens are incredibly nutritious, they’re best enjoyed as part of a varied diet. Aim to include a rainbow of fruits and vegetables in your meals for optimal health benefits.
Cost and Availability
Arugula has become widely available in most grocery stores and is generally affordable. It’s often sold in bags or clamshell containers, pre-washed and ready to eat, which can be a time-saver.
Watercress can be a bit trickier to find and may be more expensive. Look for it in the produce section of well-stocked grocery stores or at farmers’ markets. Some stores carry hydroponic watercress, which tends to be cleaner and may last longer.
Both greens are generally available year-round, but their peak season is spring through fall. You might find better prices and quality during these times.
If cost is a concern, consider growing your own. Arugula is particularly easy to grow, even in small spaces or containers. Watercress requires more specific conditions but can be grown at home with a bit more effort.
Growing at Home
Cultivation Requirements
Arugula is a gardener’s dream – fast-growing and relatively low-maintenance. It prefers cool weather and can be planted in early spring or late summer for a fall harvest.
This hardy green thrives in well-draining soil rich in organic matter. It needs full sun to partial shade and regular watering to keep the soil moist but not waterlogged.
Watercress, true to its semi-aquatic nature, has more specific growing requirements. It needs constantly moist soil or, ideally, flowing water. Many home gardeners grow it in containers with no drainage holes, keeping the soil perpetually wet.
Unlike arugula, watercress prefers partial shade, making it a good choice for areas of the garden that don’t get full sun. It also appreciates cooler temperatures and high humidity.
Both plants can be started from seeds or small seedlings. Arugula will be ready to harvest in as little as 4-6 weeks, while watercress may take 6-8 weeks to reach a harvestable size.
Harvesting and Sustainability
Arugula can be harvested using the “cut and come again” method. Simply snip off the outer leaves about an inch above the soil, leaving the center to continue growing. This way, you can enjoy multiple harvests from the same plants.
Watercress is harvested similarly, by cutting the stems about 4 inches from the tip. Like arugula, it will regrow for multiple harvests.
Both greens are considered sustainable crops, especially when grown at home. They require minimal space and resources, and their quick growth means a small area can produce a significant amount of food.
From an environmental standpoint, growing these greens at home reduces transportation costs and packaging waste associated with store-bought produce. Plus, you have full control over any pesticides or fertilizers used.
For those without garden space, both arugula and watercress can be grown in containers on a balcony or even indoors on a sunny windowsill. It’s a great way to have fresh, nutritious greens at your fingertips year-round.
Conclusion
Arugula and watercress, while different in appearance and taste, are both nutritional powerhouses that can add a zesty kick to your meals. Arugula offers versatility and a milder flavor, making it an easy addition to a wide variety of dishes. Watercress, with its bolder taste and impressive nutrient profile, packs a more potent punch both in flavor and health benefits.
Ultimately, the choice between arugula and watercress comes down to personal preference and specific nutritional needs. Better yet, why choose? Incorporate both of these fantastic greens into your diet to enjoy their unique flavors and complementary health benefits. Your palate – and your body – will reap the rewards of these verdant victors.
