By cultivating sprouts from alfalfa or lentils, you can significantly boost nutrient levels and add variety to your daily meals. Surprisingly delicious, these sprouts can be grown at home with minimal effort and basic materials. Discover the essential steps and detailed instructions on how to grow sprouts from beans, grains, seeds, and even how to cultivate your own vegetable sprouts. Check out Step 1 for more details.
Steps
Basic Instructions and Materials
Choose the type of seed to start with. Organic seeds, beans, or nuts can all be used to grow sprouts, following the same basic method. Ensure you select organic seeds or those free from pesticides to make the sprouts edible. Many seeds available on the market are treated with fungicides, pesticides, and other chemicals you wouldn't want to consume. Experiment with various seeds and beans to find out which sprouts you enjoy the most. The preparation and purchase of materials require only a small investment. Consider the following options:
- Seeds such as sesame, sunflower, buckwheat, or pumpkin
- Beans like mung beans, lentils, chickpeas, red beans, or peas
- Whole grains such as barley, corn, wheat, quinoa, amaranth, or rye
- Vegetable seeds like alfalfa, clover, radish, kale, cabbage, or fenugreek
Soak the seeds in a jar filled with filtered water overnight. Use enough water to fully cover the seeds and let them sink. Cover the jar with a breathable fabric, such as cheesecloth, mesh, or any material that allows airflow and absorbs water effectively.
- Any clean glass jar is ideal for sprouting seeds. Old mason jars or other reusable glass containers work perfectly. If your jar has a metal ring around the rim, you can use it to secure the mesh fabric. Alternatively, a rubber band, hair tie, or similar elastic can serve the same purpose.
- If you plan to grow vegetable sprouts like wheatgrass or pea shoots, you’ll need a planting tray, soil, and more time.
Drain the soaked seeds and rinse the sprouts twice daily. Typically, sprouts should be rinsed every morning and evening, then thoroughly drained to encourage germination without removing them from the jar.
- When growing bean sprouts, gently swirl them in water after a few days to separate the hulls and promote sprouting.
Maintain an optimal environment for sprouting. Control moisture by rinsing the sprouts regularly, but also ensure consistent temperatures to encourage growth. Keep the sprouts at a temperature between 10 - 20°C.
- If your home is particularly cool during certain times of the year, consider using a small heater. Placing an 8-watt reptile tank heater under the sprouting jar can help maintain warmth without overheating or damaging the seeds.
- Some sprouts, like radish sprouts, grow better in darkness initially but require light after germination to turn green and grow larger. Most sprouts thrive in normal daylight and room temperature conditions.
Use fresh sprouts immediately. Once satisfied with the sprout length, enjoy them in sandwiches, salads, or soups. Bean sprouts can be stored in the refrigerator for up to 5 days, but they will gradually turn brown and become slightly slimy, indicating it’s time to grow a new batch and discard the old ones.
- Different types of sprouts require slightly varying care and timing during soaking and germination. Some can continue growing in the jar for a few days to become taller and thinner, while others need to be transferred to a tray for better growth and flavor. Research specific sprout types for detailed instructions.
- Some sprouts need their hulls removed after a few days of germination. Swirl them in water to separate the hulls, then drain thoroughly.
Sprouts from Various Seeds
Start with a cup of your chosen seeds. Any organic, edible seeds are perfect for sprouting. Soaking helps the seeds shed their hulls and begin germination, resulting in a nutritious snack that’s similar to the original seeds but packed with more nutrients.
- Edible seeds like pumpkin, sunflower, and sesame are popular choices for sprouting.
- Vegetable seeds such as clover, alfalfa, radish, cabbage, fenugreek, or kale produce tender, nutrient-rich sprouts. These are commonly used in sandwiches, salads, and light dishes.
Soak the seeds in cold water for 4 – 6 hours. Measure the seeds into your sprouting jar, then add filtered water, covering the seeds by about 3 cm. If the seeds are dusty or dirty, rinse them before adding water.
- Soak the seeds at room temperature for 4 hours. Leaving them on the kitchen counter works well. Afterward, drain the water completely to allow the seeds to begin sprouting.
Let the seeds sprout for 12 – 24 hours. After draining, leave them undisturbed for about a day. The seeds will start to swell as they begin to grow, indicating successful sprouting. In a few days, they’ll be ready to eat!
- After a day, remove the seeds from the jar and place them on a paper towel to dry completely. Transfer them to a bowl or another container and store them in the refrigerator. They’ll stay fresh for several days and are ready to consume.
- Sesame seeds, for example, can become bitter if soaked for more than 6 hours. Remove them earlier and ensure they’re thoroughly drained.
Allow vegetable seeds to sprout for about 6 days. Vegetable sprouts take a bit longer to reach the desired length, typically around 5 days. They’re edible at any stage, but the sprouts become more tender and nutrient-rich after a few days. Continue rinsing them regularly and ensure they’re well-drained, preferably by inverting the jar to let excess moisture escape and keep the sprouts fresh.
- Use your eyes and nose to check the freshness of vegetable sprouts. They’ll start to turn brown and develop a slightly antiseptic smell when past their prime.
Consider eating nut sprouts directly. Nuts like almonds, chestnuts, and oil seeds are often soaked for a few hours to "activate" them, making them more nutritious. While the nutritional benefits of soaking nuts to trigger germination before eating aren’t fully proven, it’s an easy process to try if you’re curious.
- Soaked nuts may have enhanced nutritional value, but this doesn’t apply to roasted nuts.
Bean Sprouts
Choose one or more types of beans to sprout. Bean sprouts are perhaps the most popular and delicious type of sprout. They are nutrient-dense, flavorful, and packed with beneficial micronutrients. Common beans used for sprouting include:
- Lentils, especially green or brown varieties
- Chickpeas or garbanzo beans
- Mung beans, often sold as "bean sprouts" in stores
- Peas
Soak the beans in warm water. Start with about half a cup of dried beans (they will expand as they absorb water and shed their hulls). The water shouldn’t be too hot but warm to the touch, like a cup of tea that has cooled slightly. Soak the beans for at least 12 hours in a sprouting jar.
- Since beans expand significantly, ensure there’s enough space in the jar and that the water level is a few centimeters above the beans to fully submerge them.
Allow the beans to sprout for 3 days. Rinse the beans twice daily, inverting the jar to drain as the sprouts grow. Occasionally on the first or second day, gently shake the jar to remove the hulls. You can add a bit of water and swirl the jar to help separate them. Don’t worry if some hulls remain; they can be removed before eating if needed.
- Red beans, for example, may take up to 4 days to fully sprout and reach their best flavor. Give them extra time if necessary.
Drain the bean sprouts and store them in the refrigerator. Once the sprouting process is complete, remove the sprouts from the jar, dry them, and discard any remaining hulls. Alternatively, you can leave them as is (they’re edible but may have a slightly bitter taste). Bean sprouts can be stored in the fridge for about a week if kept dry and monitored.
- Bean sprouts are particularly delicious as a key ingredient in brothy soups, such as Vietnamese pho or other spicy dishes. They also pair well with salads and sandwiches.
Grain Sprouts
Choose a type of whole grain to sprout as a raw ingredient. Whole grains are difficult to digest without processing, which poses a challenge for raw food enthusiasts. However, sprouted grains are both digestible and nutritious. Without any cooking, you can enjoy grains like rye, wheat, barley, or corn without roasting or breaking down their micronutrients.
- Sprouted grains neutralize phytic acid, which aids digestion, and release vitamins and nutrients that raw grains lack. This makes sprouted grains ideal for oatmeal, baking, or grinding into flour.
- Hulled oats, like those sold for oatmeal, won’t sprout. To grow grain sprouts, you need whole, unprocessed, organic grains with their hulls intact. Other grains simply require soaking. For a quick and culturally inspired option, you can ferment oats with miso overnight.
Soak whole grains in warm water. Grains will triple in size during soaking, so it’s essential to use a jar or bowl large enough to accommodate this expansion. Soak the grains for about 6 hours, then drain thoroughly and let them sprout at room temperature for 2 days. Rinse the grains regularly and ensure they’re well-drained.
- Corn requires a longer soaking time, around 12 hours, before draining and beginning the sprouting process.
- Amaranth, quinoa, and millet, often mistaken for seeds or rice, are alkaline grains that sprout exceptionally well using this method.
- Barley doesn’t truly sprout, but you can stimulate the germination process, as in malting barley for brewing, by letting the grains "sprout" for about 12 hours. This initiates the process and begins hull separation.
Harvest the grain sprouts. Once the sprouts reach about 5-6mm in length, they’re ready to harvest. Give them a final rinse, then spread them on a towel to dry. Use them immediately or store them in the refrigerator.
To make flour from grain sprouts, you’ll need a food dehydrator and a grain mill. After sprouting, dehydrate the grains for 12 hours, then grind them into a fine, even flour. Sift the flour if desired. Store it in the freezer to maintain freshness, and use it like any other baking flour.
Growing Microgreens and Sprouts
Starting sprouts requires a bit more effort. The process of growing microgreens like wheatgrass, pea shoots, or sunflower sprouts is somewhat similar, though it involves more specialized equipment compared to kitchen sprouting. You can harvest multiple high-yield batches of greens, but it’s worth investing in the right setup if you want fresh wheatgrass or microgreens for your salads.
- Begin by soaking seeds, peas, or sunflower kernels in a jar and letting them sprout for a few days before thoroughly rinsing and transferring them to a tray.
- The sprouts need to develop roots about 1 cm long before moving them to the tray. This can take 3 to 4 days, depending on the growing conditions.
Prepare the seeding tray. Outdoor growing systems typically include trays for sprouting and growing, with mesh or drainage holes at the bottom to allow water to escape during regular watering. These are widely available at gardening stores, or you can create your own by drilling drainage holes in any tray large enough to hold 9 square centimeters of soil.
Fill the seeding tray with soil. Add a moderate amount of soil to the tray. You don’t need too much, as microgreens mostly grow above the surface rather than developing extensive root systems. However, ensure the soil retains enough moisture to prevent the greens from drying out.
- Moisten the soil thoroughly and let any excess water evaporate before transferring the sprouts.
- Place a small mat at the bottom of the tray to retain moisture from below, and mix in a small amount of mineral supplement—about 130 grams for a 25 x 25 cm tray—to encourage growth.
Plant the sprouts in the soil. Spread the sprouts evenly across the soil surface, ensuring they don’t overlap, as this can lead to mold. Use another tray or a simple cover like a cloth to shield the tray. Gently press the seeds into the soil to stabilize them, but avoid burying them too deeply. There’s no need to "plant" them traditionally.
Water the plants twice daily and place them in a low-light area. Cover the sprouts and check on them several times a day. Ensure they are adequately watered and well-ventilated to promote growth, and try to keep them at room temperature if possible. Starting the seed sprouts in a shaded indoor area like a storeroom can be an ideal spot.
Harvest the sprouts or grass in about 10 days. Wheatgrass will grow tall and vibrant green after a week, but allow a few extra days for the plants to reach their peak nutrient levels. Pea shoots will become lush and turn a rich green, tasting their best within 10 days. Trim the tops and let them continue growing if desired, or replant them to start your own crop.
Tips
- To grow plump bean sprouts, place a weight on top of the sprouts as they grow.
- Mixing slimy seeds like mustard or flax with 'regular' sprouting seeds such as mung beans and spelt wheat helps retain moisture and reduces the need for frequent rinsing. Mustard seeds also add a 'kick' to your sprouts. However, they can backfire if not used by the third day, as increased moisture may raise the risk of mold.
- Sunflower seeds can sprout with or without shells. Sunflower microgreens (delicious!) grow best from black-shelled seeds in about 10 days. Conversely, hulled sunflower seeds should only be sprouted for a day after soaking and are great in salads or pâtés.
- If sprouting seeds in jars or drinking glasses instead of specialized sprouting trays, a flour sifter or Swiss gold coffee filter is invaluable for draining and rinsing.
- Drinking the 'soaking' and 'rinsing' water can be quite pleasant and nutritious, especially when spiced with seeds like caraway.
- Consider purchasing an automatic sprout grower. They will water your sprouts automatically.
- Adding non-sprouting but aromatic seeds like caraway, dill, anise, or sesame can enhance the flavor of your product.
- Avoid using damaged, discolored, or deformed seeds as they yield inferior products. Do not plant too deep. The soil should be shallow enough for the seeds to sprout. Mist the soil lightly.
Warnings
- Avoid consuming sprouts if they develop mold due to poor drainage.
