Water spinach, botanically known as Ipomoea aquatica, is a staple in many Asian cuisines, from Filipino adobo to Malaysian stir-fries. Its unique combination of crunchy hollow stems and delicate, silky leaves when cooked makes it a favorite for many chefs. However, depending on location and season, it can sometimes be difficult to source. The good news is that several common leafy greens can step in to fill the gap, offering a similar taste, texture, or versatility. Choosing the right one depends on your specific recipe and desired outcome.
Understanding Water Spinach
Before diving into alternatives, it's helpful to understand what makes water spinach distinct. Its flavor is mild and slightly sweet, with a subtle nutty undertone when sautéed with ingredients like garlic. The texture is a key feature: the stalks remain crisp even after a quick stir-fry, providing a satisfying bite, while the leaves wilt down into a silky softness. Most substitutes will excel in one of these areas but may require some adjustment to cooking time to match the overall experience. For instance, you might use different parts of a vegetable or vary the cooking time to better mimic the dual-texture nature of water spinach.
Top 7 Substitutes for Water Spinach
- Regular Spinach: A common and accessible option, regular spinach is a good stand-in for the leaves of water spinach. It wilts quickly and has a mild flavor profile that pairs well with similar seasonings. However, it lacks the distinct crunchy stems, so the final texture will be different. It's best used in stir-fries or soups where the silky leaf texture is the main goal.
- Bok Choy: Also known as Chinese white cabbage, bok choy offers a great compromise between the crispy stems and tender leaves of water spinach. The stalks are crunchy and firm, while the leaves are tender and mild. Baby bok choy, in particular, has a mild, sweet flavor that works well in quick-cooking dishes. Ensure you separate the leaves from the stalks and add the stalks to the pan first to account for the difference in cooking time.
- Sweet Potato Leaves: A very close and authentic substitute for water spinach, especially in Southeast Asian cooking. The young, tender sweet potato leaves and shoots have a taste similar to conventional spinach and a comparable texture when cooked. They are a great choice for stir-fries and soups and capture that slight viscosity sometimes found in cooked water spinach.
- Watercress: For a peppery kick, watercress is an excellent alternative. While its flavor is more pronounced than water spinach, it has a good bite and wilt-down ability when cooked. This option is perfect for dishes where you want to add an extra layer of flavor and is often used as a substitute in Filipino cuisine for soups like sinigang.
- Swiss Chard: Belonging to the same family as spinach, Swiss chard is another contender. Its large, textured leaves become mild and soft when cooked, while the thick, crunchy stalks hold their shape well. This makes Swiss chard an excellent option for mimicking the two-part texture of water spinach. Use it in sautéed dishes or braises.
- Kale: While heartier and more fibrous than water spinach, kale can work as a substitute, especially baby kale. In cooked dishes, lacinato or dinosaur kale softens nicely. For salads or raw applications, baby kale is more tender, but massaging mature kale with oil can tenderize it. For stir-fries, chop the kale finely and cook it a little longer than you would water spinach to achieve a softer texture.
- Amaranth Greens: Popular in many parts of the world, amaranth greens have a tender texture and mild flavor that can substitute for water spinach leaves. They cook down very quickly, so they are best added towards the end of the cooking process in stir-fries or soups. Some varieties have reddish stalks and are often called keerai in Indian cuisine.
How to Choose the Right Substitute
Choosing your substitute depends heavily on the recipe and the desired outcome. For quick stir-fries where crispness is important, bok choy or the stems of Swiss chard are best. For soups and stews where a soft, wilted green is needed, regular spinach or sweet potato leaves are perfect. If you're looking for an authentic flavor profile in Southeast Asian cooking, sweet potato leaves are arguably the closest match. Consider the flavor intensity; watercress will introduce a peppery taste, while bok choy and sweet potato leaves are milder.

Can Frozen Greens Replace Water Spinach?
While fresh is always preferable for texture, frozen greens like spinach can be used in some applications, particularly long-simmering dishes like stews or sauces. However, their texture will be very soft and lack the crispness of fresh water spinach stems. They are not recommended for quick stir-fries where the crunchy stems are a highlight.
Consider the Season and Availability
Water spinach is often available year-round in many regions, though it peaks in summer. If it's out of stock at your usual store, check with local Asian markets, as they are more likely to carry it. Otherwise, rely on the substitutes listed here. Bok choy, spinach, and Swiss chard are widely available, while sweet potato leaves and amaranth greens might be found at specialty grocers or farmer's markets.
