Basil Microgreens: Varieties, How to Grow Them and Uses
Basil microgreens are young basil plants harvested after the cotyledons have opened and around the time the first true leaves begin to appear. They grow more slowly and stay shorter than many popular microgreens, but reward the extra patience with distinctive flavours and colours.
Basil seeds also behave differently once watered. They develop a sticky, gel-like coating called mucilage, so they should be sown dry rather than soaked beforehand. Careful moisture control is then essential for even germination and healthy growth.
This guide compares Italian, Red Opal, Lemon and Cinnamon basil microgreens, including their flavour, appearance and growing parameters. You will also learn how to sow, water and harvest them and how to deal with common growing problems.
1. What are basil microgreens?
The term basil microgreens describes a stage of growth between sprouts and mature basil. At this point, the seedlings have developed their first seed leaves, known as cotyledons, and may also be starting to produce their first true leaves.
Microgreens are different from sprouts. Sprouts are eaten at an earlier stage, often including the seed and root, while microgreens are grown in a substrate or another suitable system and cut above the growing surface. This distinction is also recognised in the FDA’s guidance on sprout production.
Basil develops more slowly and remains shorter than many common microgreen crops. Its seeds are also mucilaginous: once moistened, they form a sticky, gel-like coating. This is a normal characteristic of the seed, but it affects how basil should be sown and watered. Even moisture is important, while soaking the seeds beforehand can make them clump together and become difficult to spread evenly.

2. Basil microgreen varieties compared
The four basil varieties differ most clearly in flavour and appearance. Italian has the most familiar basil character, Red Opal brings purple-red colour, while Lemon and Cinnamon offer more distinctive aromatic profiles. The table provides a quick comparison before we look at where each variety works best.
Growing times are approximate and may vary with temperature, light, moisture and the chosen harvest stage.
Of the four varieties, Italian basil microgreens provide the most classic basil profile. Their intense, refreshing flavour is easy to recognise, making them a versatile option for professional kitchens as well as home growers.
The crop develops white stems and green leaves, giving it the familiar fresh appearance associated with basil. It is sown at 20 g per 10x20 tray and is classed as medium in difficulty.
Italian basil works particularly well with tomatoes, pasta and salads. It can also be scattered over pizza after baking, when the leaves retain their colour, texture and fresh flavour, or used as a simple garnish for savoury dishes.
Colour is the main reason to choose Red Opal, making it an excellent option for growers looking for purple basil microgreens. Light pink stems support purple-red leaves, although some natural variation between greener and more deeply coloured leaves may occur as the crop develops.
The flavour remains recognisably basil-like but is sweeter than that of the Italian variety. This makes Red Opal useful when you want a garnish to provide strong visual contrast without taking the dish in a completely different flavour direction. It stands out particularly well against pale ingredients, green salads and open sandwiches.
Lemon basil microgreens take the flavour in a lighter direction. Their sweetness is accompanied by a clear citrus note, while white stems and green leaves with a subtle lemon tint give the crop a fresh, delicate appearance.
That profile suits fish and seafood especially well. Lemon basil can also add a fresh finish to light salads, cold drinks and desserts without the heavier character of classic basil. For plating, use it where both a green garnish and a brighter, citrus-led aroma will complement the dish.
Cinnamon basil microgreens combine basil with notes of mint and fresh cinnamon. The result is herbal and aromatic rather than similar to dried cinnamon spice.
This variety contains approximately 950 seeds per gram, compared with 700 for the other three. Its recommended sowing density is therefore lower, at 15 g per 10x20 tray. That difference is worth checking before sowing rather than applying the same rate to every basil variety.
Its distinctive profile works with drinks, fruit and desserts, as well as selected Asian-inspired dishes. The green leaves can also be used decoratively where a less conventional basil aroma is welcome.
3. How to grow basil microgreens step by step
Basil needs more patience than many faster-growing microgreens. Its seeds form a gel-like coating when wet, the seedlings stay relatively low, and moisture must be managed carefully throughout germination. The exact growing time still depends on the variety, conditions and chosen harvest stage.
What you need
Before sowing, prepare:
- seeds intended for microgreen production;
- a clean growing tray with drainage and a bottom tray;
- your chosen growing medium or a proven hydroponic system;
- clean water and a fine mister for the initial watering;
- suitable light and good air circulation;
- kitchen scales and the sowing data for your chosen variety.
Start with clean equipment and a growing surface that is evenly moist but not waterlogged. If you use a hydroponic setup, follow the instructions for that particular system rather than transferring soil-growing advice directly to it.
Do not soak basil microgreen seeds
Do not soak basil seeds before sowing. When each seed comes into contact with water, it produces a sticky, gel-like coating known as mucilage. This is a natural feature of basil and other mucilaginous seeds, but soaking them in a container makes the seeds stick together and become difficult to spread.
Instead, distribute the dry seeds directly over the prepared surface. Aim for even coverage, then mist them carefully so that the water activates the coating without washing the seeds into clusters. During germination, keep the gel layer from drying out. At the same time, avoid adding so much water that the seeds sit in puddles.
You can see this process in more detail in our guide to the 📚gel-like coating around mucilaginous microgreen seeds. We also explain how basil differs from varieties that benefit from soaking in 📚which microgreen seeds to soak before sowing.
Sow at the rate for your variety
Weigh the seeds rather than estimating the amount by eye. For the current MP SEEDS varieties, the recommended rates are:
- Italian: 20 g per 10x20 tray;
- Red Opal: 20 g per 10x20 tray;
- Lemon: 20 g per 10x20 tray;
- Cinnamon: 15 g per 10x20 tray.
These figures apply specifically to a 10x20 tray. If your tray has different dimensions, use the MP SEEDS sowing density calculator to adjust the amount to its growing area.
Spread the seeds as evenly as possible, paying particular attention to the edges and corners. Do not treat a rate such as 4 g or 1 oz found elsewhere as a universal standard for basil. Tray dimensions, growing systems, seed sources and production goals differ, so the relevant data should always be matched to the specific variety and setup.
Germination and blackout
Once sown, the seeds need close contact with the moist growing surface. Keep the conditions stable and warm enough for basil, without allowing the tray to flood or dry out. Avoid relying on a fixed temperature range unless it has been confirmed for the current seed lot and production method.
Italian, Red Opal, Lemon and Cinnamon basil have a confirmed blackout period of 4–6 days. Check the tray during this stage rather than relying only on the calendar, as germination can progress differently under different conditions.
Blackout supports germination and can help the naturally short seedlings develop slightly longer stems. This does not mean that one particular weighting method is required in every setup. The aim is to create suitable germination conditions, not to keep the crop covered for as long as possible. Extending blackout unnecessarily may weaken the crop, while standing water and insufficient airflow can increase the risk of poor results.

Light, watering and airflow
After blackout, move the tray under suitable, evenly distributed light. Uneven coverage can cause the seedlings to lean towards the light source and make the crop less uniform.
Once the roots are established, water carefully from below if the tray and growing system allow it. This helps keep unnecessary moisture off the leaves and delicate stems. Add enough water to keep the growing medium moist, then check that it is not remaining saturated. Basil needs consistent moisture, but a permanently waterlogged tray does not provide suitable conditions for the roots.
Air should also be able to move around the short, dense crop. The purpose is gentle, continuous circulation rather than a strong stream directed at the seedlings.
When growing basil microgreens hydroponically, water management and feeding should follow the instructions for the chosen system. MP SEEDS recommends Red Opal as a suitable option for hydroponic growers, although this does not mean it is the only basil variety that can be grown in this way.
When and how to harvest
For the four varieties covered here, the current total growing-time range is 14–28 days. Use it as a planning guide rather than a fixed harvest date. Look at the crop itself: its stage of leaf development, colour, overall condition and flavour will tell you more than the number of days alone.
Harvest with a clean, sharp tool, cutting the stems just above the growing surface. Basil microgreens stay low, so leave enough clearance to avoid picking up particles of the growing medium with the crop.
Whenever possible, harvest the leaves dry. If washing is necessary, use water that is safe for food handling and dry the microgreens thoroughly before placing them in storage. Excess moisture left on the harvested crop can reduce its quality.
4. Common problems when growing basil microgreens
Basil can react quickly to uneven moisture, particularly during germination, when the gel coating must remain moist without becoming waterlogged. Use the table to identify possible causes, but assess the entire tray before deciding what went wrong.
5. How to use and store basil microgreens
Basil microgreens are best used as a fresh finishing ingredient. Adding them near the end of preparation helps preserve their delicate texture, colour and aroma. Their small size makes them easy to distribute across a dish, but the right variety depends on the flavour you want to emphasise.
Italian has the most classic basil microgreens taste of the four varieties. Use it with tomatoes, pasta, salads and sandwiches, or scatter it over pizza after baking. It can also finish soups just before serving, providing fresh basil character without prolonged exposure to heat.
Red Opal has a sweeter basil profile, but its purple-red leaves make appearance just as important as flavour. It works well where the garnish needs to contrast with pale ingredients, green salads, open sandwiches or softly coloured soups. A small amount can introduce colour without changing the overall direction of the dish.
For fish and seafood, Lemon provides a lighter option. Its sweet, citrus-led aroma also suits salads, cold drinks and desserts. Use it where a fresh green finish and a bright aromatic note complement the other ingredients.
Cinnamon moves in a warmer direction, combining basil with notes of mint and fresh cinnamon. Try it with fruit, desserts and drinks or as a finishing herb for selected Asian-inspired dishes. Its flavour is herbal rather than comparable to dried cinnamon spice, so tasting it alongside the finished dish is the best way to judge the amount.
Harvest basil microgreens as dry as possible. Place the crop in a clean container and keep it chilled. Avoid adding wet leaves directly to storage, as retained moisture can reduce quality. If washing is necessary, use water suitable for food handling and dry the microgreens thoroughly before packing them. Storage time varies with the condition of the crop, moisture and handling, so test it under your own production conditions rather than relying on a fixed shelf life.
6. Basil microgreens nutrition: what does research show?
[product id="40, 86"]
Research into basil microgreens has identified nutrients, pigments and antioxidant compounds in the harvested plants. However, basil microgreens nutrition is not identical across every crop. Results can vary with the variety or basil type, lighting and other growing conditions.
Studies comparing different basils suggest that green, red or purple, and lemon types may differ in their profiles of pigments and other bioactive compounds. Findings from one cultivar or production method should not therefore be applied automatically to every basil microgreen.
Discussions of basil microgreens benefits should remain proportionate to the evidence. Detecting a nutrient or antioxidant compound in a laboratory analysis does not demonstrate that eating the crop will prevent or treat disease.
7. Frequently asked questions
Are basil microgreens easy to grow?
Basil microgreens are slower and slightly more demanding than many popular microgreens. Their mucilaginous seeds, sensitivity to moisture and naturally low growth can make sowing and harvesting less straightforward. Once you establish a repeatable method for controlling moisture, blackout and airflow, however, the crop becomes much easier to manage.
Is micro basil the same as regular basil?
Micro basil comes from the same type of plant as regular basil but is harvested at a much earlier stage. It is smaller and more delicate, with a shorter production time than mature basil. It is usually added as a fresh garnish, and the exact flavour profile depends on the variety.
Do you soak basil microgreen seeds?
No. Basil seeds form a sticky, gel-like coating when they come into contact with water. Soaking causes them to clump together, making even sowing difficult. Spread the dry seeds directly over the growing surface, then mist gently and keep the coating moist during germination.
How long do basil microgreens take to grow?
The Italian, Red Opal, Lemon and Cinnamon varieties covered in this guide have an approximate total growing time of 14–28 days. The actual harvest date depends on the variety, conditions and preferred stage of development, so assess the leaves, colour, condition and flavour rather than relying only on the calendar.
Can you grow basil microgreens hydroponically?
Yes, basil microgreens can be grown hydroponically when the chosen system provides suitable moisture control, hygiene and airflow. Follow the instructions for your particular setup.
Which basil microgreen variety should I choose?
Choose according to flavour, appearance and growing system. Italian offers the most classic basil character, while Red Opal adds purple-red colour. Lemon brings a sweet citrus note, whereas Cinnamon combines basil with mint and fresh cinnamon tones.
8. Conclusion
Choose Italian basil microgreens for a classic, intense flavour, Red Opal for purple-red colour, Lemon for a fresh citrus note or Cinnamon for its distinctive basil, mint and cinnamon profile. Whichever variety suits your menu, remember three essentials: do not soak the seeds, follow the sowing rate recommended for that variety, and keep the growing surface consistently moist without waterlogging it.
