Cooking with Fresh Herbs
Fresh herbs can change a simple garden harvest into a complete meal. A handful of basil can lift a tomato sauce, dill can transform cucumbers or potatoes, rosemary can flavour a tray of roasted vegetables, and parsley can bring freshness to soups, grains and sauces.
The most successful herb cooking begins with timing. Some herbs release their flavour slowly and tolerate long cooking. Others are delicate and are best added shortly before serving. Learning this distinction prevents fresh herbs from becoming either overpowering or almost undetectable.
Harvest Herbs at Their Best
Harvest culinary herbs when the leaves are healthy and dry.
Once morning dew or rain has evaporated, cut the stems with clean scissors or secateurs. In hot weather, harvesting during the cooler part of the day can reduce wilting.
For leafy herbs, regular picking encourages fresh growth and can delay flowering. Take small amounts from several parts of the plant rather than stripping one section completely.
Where practical, harvest only as much as will be used immediately. The interval between garden and plate is one of the main advantages of growing herbs at home.
Avoid harvesting leaves that are:
Diseased.
Mouldy.
Heavily damaged by pests.
Contaminated with animal waste.
Wilted beyond recovery.
Recently treated with a product that has a stated harvest interval.
Identify every herb confidently before eating it. Do not assume an unfamiliar plant is edible because it smells aromatic or resembles a culinary herb.
Wash and Prepare Fresh Herbs
Herbs can collect soil, insects and dust even when they appear clean.
Rinse them gently under clean, cool running water. Large bunches can be moved through a bowl of clean water and then given a final rinse.
Dry the herbs thoroughly with a salad spinner or clean cloth. Excess water dilutes dressings and sauces and can make chopped herbs cling together.
Remove:
Tough or woody stems.
Yellow leaves.
Flower stalks if they are coarse.
Damaged foliage.
Hidden insects.
Do not chop delicate herbs until shortly before use. Once cut, their exposed surfaces begin losing aroma and freshness.
Understand Soft and Woody Herbs
Culinary herbs can be divided loosely into two groups according to their texture and how they behave during cooking.
Soft Herbs
Soft herbs have tender leaves and stems. They are usually best added towards the end of cooking or used fresh.
Examples include:
Basil.
Parsley.
Coriander leaf.
Dill.
Chives.
Chervil.
Mint.
Tarragon.
Long cooking can dull their colour and reduce their fresh aroma.
Add soft herbs:
Shortly before serving.
After a dish has been removed from the heat.
To cold sauces and dressings.
As a generous finishing ingredient.
In repeated stages when both background and fresh flavour are wanted.
The tender upper stems of parsley and coriander can often be chopped with the leaves. Tougher lower stems can be added to stock or cooked sauces if their flavour is suitable.
Woody Herbs
Woody herbs have firmer leaves and tougher stems. They generally tolerate longer cooking and release their flavour gradually.
Examples include:
Rosemary.
Thyme.
Sage.
Bay.
Winter savory.
Oregano.
Marjoram.
Whole sprigs can be added early to soups, stews, sauces and roasting dishes, then removed before serving.
Strip leaves from coarse stems when the herb will remain in the finished dish.
Woody herbs can become dominant or bitter when used excessively. Begin with a modest quantity and add more if needed.
Add Herbs at the Right Time
The timing of an herb can matter as much as the quantity.
Add Early
Use robust herbs early when they need time to infuse a dish.
Suitable examples include:
Bay in soups and stews.
Rosemary with roasting vegetables.
Thyme in slow-cooked sauces.
Sage in braised dishes.
Oregano in long-cooked tomato mixtures.
Add Late
Add delicate herbs during the final minutes to preserve their aroma and colour.
Suitable examples include:
Basil in tomato sauce.
Dill in soups and cooked vegetables.
Parsley in stews and grain dishes.
Chives in egg and potato dishes.
Coriander leaf in curries and soups.
Tarragon in light sauces.
Add in Layers
Some dishes benefit from the same herb at more than one stage.
A small amount can be cooked into the base, followed by a fresh handful shortly before serving. This creates both depth and freshness.
Chop Herbs without Bruising Them
Use a sharp knife and a clean, dry chopping board.
A blunt knife crushes the leaves and leaves much of their flavour on the board. Gather the herbs loosely and cut them with controlled strokes rather than repeatedly pressing them into a wet paste.
Chop rosemary and sage finely because large pieces can be tough. Basil can be torn or sliced shortly before use. Chives are usually easiest to snip or slice into short lengths.
Mint can darken after chopping, so prepare it as close to serving as possible.
Cook with Basil
Basil is closely associated with tomatoes, but it is also useful with courgettes, aubergines, peppers, beans and many fruit dishes.
Add fresh basil near the end of cooking. Prolonged heat reduces its aroma.
Use it in:
Tomato salads.
Pasta sauces.
Soups.
Pesto.
Courgette dishes.
Bean salads.
Sandwiches.
Herb dressings.
Fruit salads.
Different basils can bring notes of lemon, spice, anise or cinnamon. Taste the variety before deciding how much to use.
Remove flower heads regularly if continued leaf production is wanted. The flowers are edible and can be used as a garnish when their flavour is pleasant.
Cook with Parsley
Parsley is one of the most adaptable garden herbs.
Flat-leaved and curly forms can both be used in:
Soups.
Stocks.
Sauces.
Salads.
Grain dishes.
Potato dishes.
Egg dishes.
Herb butters.
Stuffings.
Garnishes.
The tender stems contain considerable flavour. Chop them finely or add them earlier than the leaves.
Parsley combines well with garlic and citrus. It can also balance richer ingredients without dominating them.
Cook with Coriander
Coriander leaves have a distinctive flavour that can be lost through long cooking.
Add the leaves at the end of:
Curries.
Soups.
Bean dishes.
Rice dishes.
Salsas.
Chutneys.
Noodle dishes.
The tender stems can be chopped and used with the leaves. The roots are also used in some regional cuisines, but they must be cleaned thoroughly.
Allow some plants to flower if coriander seed is wanted. The fresh leaves and dried seeds have different flavours and should not be treated as direct substitutes.
Cook with Dill
Dill works particularly well with:
Cucumbers.
Beetroot.
Potatoes.
Beans.
Cabbage.
Eggs.
Yoghurt.
Fish.
Pickles.
Add the soft leaves late in cooking. The stems and flower heads can flavour tested pickle recipes when specifically called for.
Dill flowers attract beneficial insects in the garden, so allowing some plants to bloom can support both the kitchen and the growing space.
Cook with Mint
Mint can be sweet, sharp, cooling or strongly mentholated, depending on the variety.
Use it with:
Peas.
Potatoes.
Courgettes.
Cucumbers.
Beans.
Yoghurt.
Fruit.
Salads.
Grain dishes.
Drinks.
Spearmint-type varieties are generally more versatile for cooking than intensely mentholated mints.
Mint spreads vigorously in many gardens, making it a reliable source of leaves but also a crop that may need containment.
Add chopped mint near the end of cooking or use it fresh.
Cook with Chives
Chives provide a mild onion flavour and are best used fresh or added shortly before serving.
Use them in:
Egg dishes.
Potato salads.
Soups.
Soft cheeses.
Herb butter.
Dressings.
Sandwiches.
Savoury baking.
The flowers are edible and can be separated into individual florets. Their flavour is stronger than that of the leaves, so use them sparingly.
Do not use flowering heads that have become tough, dirty or heavily visited by insects without cleaning and inspecting them carefully.
Cook with Rosemary
Rosemary has a strong flavour and withstands long cooking.
Use it with:
Roasted potatoes.
Root vegetables.
Tomatoes.
Beans.
Bread.
Stews.
Grilled vegetables.
Suitable meat dishes.
Whole sprigs can be added during cooking and removed before serving. If the leaves will remain in the dish, chop them finely.
Rosemary stems can become hard and pointed. Ensure that woody pieces are removed from soups, sauces and baked dishes.
A little rosemary can flavour an entire tray of vegetables. Too much can produce a medicinal or bitter result.
Cook with Thyme
Thyme is versatile and generally less dominant than rosemary.
It works well in:
Tomato sauces.
Soups.
Stocks.
Stews.
Bean dishes.
Roasted vegetables.
Stuffings.
Mushroom dishes.
Savoury baking.
Young tender stems can sometimes be chopped with the leaves. Remove older woody stems before serving.
Lemon thyme adds a citrus note without introducing extra liquid.
Cook with Sage
Sage has a powerful, savoury flavour and should be used with restraint.
It combines well with:
Pumpkin and winter squash.
Beans.
Potatoes.
Onions.
Stuffings.
Butter-based sauces.
Rich vegetable dishes.
The leaves can be fried briefly until crisp, chopped into fillings or cooked whole to flavour a sauce.
Older leaves may be tough, so choose fresh, healthy growth for dishes in which the herb will remain visible.
Cook with Oregano and Marjoram
Oregano has a robust flavour suited to tomatoes, beans, peppers, courgettes and aubergines.
Marjoram is usually milder and sweeter.
Both can be used in:
Tomato sauces.
Roasted vegetables.
Bean dishes.
Flatbreads.
Marinades.
Stuffings.
Soups.
Oregano often develops a particularly useful flavour when dried, while fresh marjoram can be excellent when added near the end of cooking.
Cook with Tarragon
Tarragon has a distinctive anise-like character.
It works well with:
Eggs.
Potatoes.
Beans.
Carrots.
Mushrooms.
Vinegar-based dressings.
Mustard sauces.
Suitable poultry and fish dishes.
Use it sparingly until its strength is familiar. Add fresh leaves near the end of cooking.
Not every plant sold or grown as tarragon has the same flavour. Taste a small leaf before using a large quantity.
Make a Flexible Garden Pesto
Pesto does not have to be made from basil alone. Parsley, rocket, tender carrot leaves and other correctly identified edible greens can be used alone or in combinations.
Ingredients
2 packed cups clean, dry herb leaves or suitable edible greens
60 g nuts or seeds
1–2 cloves garlic
50 g finely grated hard cheese
120 ml oil, approximately
Salt and pepper to taste
Lemon juice to taste, optional
Method
Chop the nuts or seeds and garlic in a food processor.
Add the herbs and process in short bursts until finely chopped.
Add the cheese and enough oil to reach the preferred consistency. Season to taste and add a little lemon juice if wanted.
Avoid processing for longer than necessary, as heat and excessive blending can dull the fresh flavour.
Storage
Transfer the pesto to a clean container, cover and refrigerate immediately. Use it within four days or freeze it for longer storage.
Freeze small portions in suitable trays or containers, then transfer the frozen portions to clearly labelled freezer packaging.
Do not can pesto. Oil, garlic, herbs and cheese create a mixture for which ordinary water-bath processing is not a safe home-preservation method.
Make Herb Butter
Herb butter is a useful way to preserve small quantities of several herbs.
Soften butter and mix it with finely chopped clean, dry herbs. Add garlic, citrus zest or pepper if wanted.
Suitable combinations include:
Parsley and chive.
Sage and thyme.
Dill and chive.
Rosemary and garlic.
Basil and parsley.
Shape the butter into a log or divide it into small portions. Refrigerate for immediate use or freeze.
Use herb butter on vegetables, bread, potatoes, grains or suitable cooked proteins.
Label frozen portions clearly because different herb mixtures can look similar.
Make Fresh Herb Sauces
Fresh herbs can form the basis of uncooked sauces without requiring a fixed recipe.
Combine chopped herbs with ingredients such as:
Yoghurt.
Mustard.
Vinegar.
Citrus juice.
Capers.
Chopped pickles.
Garlic.
Chilli.
Oil.
Build the sauce gradually and taste as it develops.
Fresh herb sauces should be kept refrigerated and used promptly. Their short life is part of their character; they are intended to preserve freshness for a few meals rather than for an entire season.
Add Herbs to Salads
Herbs need not be restricted to small garnishes.
Parsley, mint, basil, dill and coriander can be used by the handful in mixed salads. They can provide much of the dish’s flavour and reduce the need for a complicated dressing.
Keep leaves whole or tear them gently where possible. Finely chopped herbs lose their texture quickly in wet dressings.
Add delicate herbs shortly before serving.
Use Herb Flowers
The flowers of many familiar culinary herbs are edible, including those of:
Basil.
Chives.
Dill.
Coriander.
Thyme.
Oregano.
Rosemary.
Sage.
Mint.
Their flavour may be similar to the leaves but stronger, milder or sweeter.
Use them sparingly in salads, herb butter and garnishes.
Only eat flowers from plants that have been positively identified as edible culinary herbs. Do not use flowers treated with unsuitable garden chemicals or collected from roadsides and other potentially contaminated places.
Freeze Fresh Herbs
Freezing usually preserves the character of tender herbs better than drying, although the leaves lose their fresh texture.
Wash the herbs, dry them thoroughly and remove coarse stems. Chop or leave them whole according to their intended use.
Freeze them:
In small freezer containers.
In labelled freezer bags.
In measured portions.
In water for adding to soups and stews.
As finished pesto.
Mixed into butter.
Frozen herbs are best added directly to cooked dishes.
Do not expect thawed basil, parsley or dill to behave like fresh garnish leaves. Their flavour can remain useful even though their structure collapses.
Further freezing guidance can be found in the Harvesting & Storage section.
Dry Herbs
Drying suits robust, relatively low-moisture herbs such as thyme, oregano, rosemary, sage and marjoram.
Basil, parsley, mint and dill can also be dried, although their flavour may change more noticeably.
Harvest healthy leaves, wash if necessary and dry them thoroughly. Use a dehydrator or another controlled drying method. Protect the herbs from dust, insects, moisture and excessive heat.
The leaves must be completely dry before storage. Pack them in airtight containers away from light and heat.
Keep dried leaves as whole as practical and crumble them when needed. This helps retain their aroma.
Label every container with the herb and drying date.
Further instructions on drying herbs are available in the Harvesting & Storage section.
Take Care with Herbs in Oil
Fresh herbs stored in oil can create conditions in which the bacteria responsible for botulism may grow.
Do not store homemade herbs in oil at room temperature.
Unless following a scientifically tested acidification procedure, refrigerate homemade herb-and-oil mixtures immediately and use them within four days, or freeze them for longer storage.
This includes:
Pesto.
Chopped herbs in oil.
Garlic and herb mixtures.
Fresh chilli and herb oil.
Dried tomato mixtures containing herbs or garlic.
Commercial shelf-stable herb oils are prepared using controlled processes that should not be assumed to occur in a home kitchen.
Oil may slow exposure to air, but it does not make fresh herbs safe for cupboard storage.
Use Herbs Before They Are Wasted
Small amounts of leftover herbs can be added to:
Soup.
Stock.
Omelettes.
Fritters.
Salad dressing.
Herb butter.
Pesto.
Cooked grains.
Bean dishes.
Roasted vegetables.
Mixed soft herbs can often be used together, but combine strong woody herbs more carefully.
If a bunch is beginning to wilt but remains sound, place the cut stems in water briefly or use the leaves in a cooked dish. Discard herbs that are slimy, mouldy or unpleasant-smelling.
Record Which Herbs Are Most Useful
It is easy to grow many herbs but repeatedly cook with only a few.
Your Growing Companion can help record sowings, plant locations and harvests. At the end of the season, consider:
Which herbs were used most often.
Which varieties had the best flavour.
Which plants produced too much or too little.
Which herbs dried or froze successfully.
Whether tender herbs need successional sowing.
Which perennial herbs should be divided or replaced.
This helps create a herb garden based on genuine kitchen use rather than novelty alone.
Let Fresh Herbs Do the Work
Herbs are most valuable when they become part of everyday cooking rather than an occasional decoration.
Harvest them regularly, wash and dry them carefully, and add them at the stage that best suits their character. Cook robust herbs slowly and finish dishes with tender leaves. Freeze or dry manageable quantities and treat every herb-and-oil mixture as a refrigerated or frozen food unless a tested method states otherwise.
A small selection of well-used herbs can bring variety to an entire season of garden produce.
