How to Cook Purslane

Reading time: 12 minutes

🌿 Introduction

Purslane (Portulaca oleracea L.) is a hardy succulent that often sprouts in gardens and sidewalk cracks but deserves a place in the kitchen. Its crisp, juicy leaves and stems carry a lemony, slightly salty flavor reminiscent of spinach and watercress. For centuries it has been eaten across Europe, the Mediterranean and Mexico where it appears raw in salads or cooked in soups, stews and omelets. Beyond its tart crunch, purslane is loaded with nutrients—its raw leaves are rich in vitamin A (1320 IU per 100 g) and vitamin E (12.2 mg per 100 g), giving it higher levels of these antioxidants than broccoli, tomatoes or lettuce. It is also one of the best vegetable sources of omega-3 fatty acids, delivering five to seven times more alpha-linolenic acid than spinach.

This guide explains how to select, prepare and cook purslane, offers recipe ideas, highlights nutritional benefits and cautions, and shows why microgreens are an extra-nutritious way to enjoy this underrated plant.

💧 Choosing and Preparing Purslane

Fresh purslane thrives in warm weather. Look for smooth, reddish stems that branch out with spatulate green leaves and small yellow flowers. Harvest or buy young plants; older leaves can become tough and sour. Because purslane grows close to the ground, dirt often collects in crevices, so rinse stems and leaves thoroughly in cold water. Trim away the fibrous taproot and discard any woody basal stems; the tender stems, leaves and flowers are all edible. For microgreens, sow seeds in trays, keep moist and harvest within 8–14 days when the cotyledons and first true leaves appear. These young shoots carry a bright citrus-like flavor and even higher concentrations of antioxidants than mature leaves.

🥗 Enjoying Purslane Raw

Purslane’s crunchy texture makes it ideal for raw dishes. In Mediterranean countries it is tossed with cucumbers and olive oil–vinegar dressing or mixed with yogurt and garlic for Turkish salads. Greek cooks fold purslane into salads with tomatoes, onions and feta, pairing its mild acidity with salty cheeses. Its tartness also shines in smoothies and fresh juices. Microgreens add a lemony zip to sandwiches or can be sprinkled over grain bowls for a nutritional boost. When served raw, purslane retains its vitamin C and B vitamins and provides a satisfying low-calorie crunch—100 g contains just 16 calories and 93 % water.

🌞 Steaming and Blanching

Light cooking softens purslane without completely altering its succulent character. Steaming for 3–5 minutes yields tender stems that resemble spinach; early American settlers often served steamed purslane with a pinch of salt and butter. Blanching in boiling water for one minute, then plunging into ice water, removes some of the oxalic acid (a compound that can contribute to kidney stones). Blanched purslane can be tossed with lemon juice and olive oil or stirred into warm potato salads. Because the leaves are high in pectin, they require little oil when sautéed and can help emulsify dressings.

🍳 Sautéing and Stir-Frying

Sautéing brings out purslane’s earthy notes. In Mexico, it is cooked with salsa verde and eggs (verdolagas con huevos) or braised with pork as in the classic dish carne de puerco con verdolagas. For a quick side, heat olive oil or butter, add chopped garlic, toss in washed purslane and sauté for 5–7 minutes until wilted. An Ecuadorian preparation braises purslane with garlic, tomatoes and hot chilies. Tender stems cook quickly, but larger stems should be trimmed or cooked longer. The moisture content (about 93 %) means purslane wilts faster than tougher greens and can thicken pan juices due to its mucilaginous properties.

🥘 Soups, Stews and Thickening

When simmered, purslane’s pectin and mucilage act as a natural thickener. Greek cooks fry purslane with olive oil, tomatoes, onions, garlic and oregano, sometimes adding feta cheese for a creamy stew. In Mexican cuisine, it is stewed with pork or beef, added during the last 10 minutes of cooking to preserve texture. The University of Wisconsin notes that cooked purslane becomes mucilaginous, making it useful for thickening soups and stews. A potato–purslane soup is an easy entry: sauté onions, add diced potatoes and broth, simmer until tender, then stir in chopped purslane and cook just until the greens wilt. The mucilaginous quality gives the soup body without added flour or cream.

🧠 Nutritional Benefits

Purslane’s nutritional profile rivals many cultivated greens. A 100-g serving provides 26 % of the daily value (DV) for vitamin A and 35 % for vitamin C. It contains significant amounts of vitamin E, B vitamins (thiamine, riboflavin, niacin, folate and others), and minerals such as potassium, magnesium, calcium and iron. The plant’s red stems and leaves accumulate omega-3 fatty acids, particularly alpha-linolenic acid (ALA) and small amounts of eicosapentaenoic acid (EPA)—rare among terrestrial vegetables. Proximate analysis shows that fresh purslane contains about 18 % protein, 44 % carbohydrates and 21 % dietary fiber by dry weight, along with phenolic compounds and flavonoids that give it antioxidant and anti-inflammatory properties. These nutrients may support heart health and immune function. Microgreens further concentrate phytonutrients; studies have found that 15-day-old purslane microgreens exhibit 24 % higher antioxidant capacity than mature plants.

⚠️ Health Considerations

Despite its benefits, moderation is crucial. Purslane contains high amounts of oxalic acid and nitrates. Oxalates can bind minerals like calcium and magnesium in the digestive tract, potentially reducing absorption and forming kidney stones in susceptible individuals.

A case report described a woman who developed acute kidney injury after consuming three-quarters of a kilogram of stir-fried purslane, highlighting the risk of excessive intake. People with a history of kidney stones should limit consumption and avoid eating large quantities at once. Blanching, boiling or pickling reduces oxalate content, and adding dairy such as yogurt or feta cheese may further reduce oxalate absorption.

🌱 Growing and Harvesting Tips

Purslane is a resilient annual that thrives in poor soil. It germinates quickly and can be harvested every 10–20 days. Identify it by its smooth, reddish, prostrate stems and spoon-shaped leaves; the bright yellow flowers produce shiny black seeds that self-sow readily. Avoid confusing purslane with similar-looking toxic plants; if in doubt, consult a local extension office. For microgreens, sow seeds densely in shallow trays under light; harvest after 8–14 days by snipping above the soil line. Microgreens require less space and deliver concentrated flavors and nutrients.

🌸 Conclusion

Purslane is more than a weed—it is an underappreciated culinary green bursting with nutrition and culinary versatility. Its crisp, lemony leaves can be eaten raw in salads, quickly steamed or blanched, sautéed with garlic and tomatoes, or simmered to thicken soups and stews. With ample vitamin A, vitamin C, vitamin E, omega-3 fatty acids and beneficial phytochemicals, purslane offers health benefits comparable to many cultivated vegetables. For those seeking variety, microgreens provide an easy, nutrient-dense garnish that grows in days. By understanding how to select, prepare and cook purslane and by consuming it in moderation, you can transform this hardy plant into a delicious part of your diet.
