Leaves: The Classic Peppery Green
Arugula leaves are the most widely consumed part of the plant, known for their distinct, peppery flavor profile. Younger, smaller leaves offer a milder, sweeter taste, while older, larger leaves develop a more pungent, almost bitter intensity. This versatility allows them to be used in many culinary applications.
Raw vs. Cooked Leaves
- Raw leaves: Best used in salads, on sandwiches, or as a garnish for pizzas and pastas. The peppery bite is most pronounced when the leaves are raw.
- Cooked leaves: Lightly sautéing the leaves mellows their peppery flavor, making them a great addition to sauces, soups, and pasta dishes. They wilt quickly, similar to spinach.
Flowers: The Delicate, Peppery Garnish
When the weather warms, arugula plants will bolt, shooting up a stalk with delicate white or pale yellow flowers, often with purple veins. These flowers are not only beautiful but also completely edible and add a subtle, nutty-peppery flavor.
How to Use Arugula Flowers
- Garnish: Sprinkle the flowers on salads, soups, or quiches for a decorative and flavorful touch.
- Flavoring: Incorporate them into egg dishes or use them to make flavorful vinegar infusions.
Seed Pods and Seeds: The Hidden Spice Source
After the flowers bloom, the plant produces elongated seed pods (siliquae). Both the young pods and the mature seeds can be used in cooking, adding a crunchy, peppery texture and flavor.
Using Arugula Seeds and Pods
- Young seed pods: These are crunchy and can be eaten raw, tossed into salads, or stir-fried.
- Mature seeds: Once the pods dry, the mature seeds can be harvested. In some culinary traditions, these seeds are pressed to make a pungent, mustard-like oil.
Stems: The Often-Overlooked Component
While usually discarded, the stems of the arugula plant are also edible, though their use depends on the plant's maturity.
How to Handle Arugula Stems
- Young stems: The stems on young arugula are tender and can be eaten along with the leaves without any special preparation.
- Mature stems: As the plant matures, the stems can become tough and fibrous. In this case, it is best to remove the thickest parts before use, though they can still be used in cooked dishes where they will soften.
The Roots: The Unsung Part
Unlike many root vegetables, arugula roots are not a primary culinary feature but are still technically edible. They have a similar peppery flavor to the leaves and are best used when the plant is young.
Comparison Table: Arugula's Edible Parts

| Leaves | Peppery, mildly bitter (young), pungent (mature) | Tender, crisp | Salads, sandwiches, pasta, pizza topping, soups | Most popular and versatile part of the plant. |
| Flowers | Mildly peppery, nutty | Delicate | Garnish for salads, soups, egg dishes | Adds visual appeal and subtle flavor. |
| Seed Pods (Young) | Peppery, crunchy | Crisp | Stir-fries, salads | A crunchy addition with a spicy kick. |
| Seeds (Mature) | Pungent, mustard-like | Small, hard | Pressed for oil, ground as a spice | Historically used for oil, especially in parts of Asia. |
| Stems | Peppery | Tender (young), tough/fibrous (mature) | Raw (young), cooked (mature) | Use younger stems; remove tougher stems from mature plants. |
Potential Health Benefits
Beyond their culinary uses, all edible parts of arugula are packed with beneficial nutrients. Arugula is a cruciferous vegetable, similar to broccoli and kale, and is rich in vitamins A, C, and K, as well as minerals like calcium and potassium. It also contains compounds that may offer antioxidant, anti-inflammatory, and even potential anti-cancer properties.
