Winter soups from the freezer: batch, label, reheat
There is a particular kind of relief in opening the freezer on a dark January evening and finding a container of soup you made weeks ago. It takes planning on a calm Sunday, and it pays you back on every cold, rushed weeknight. Here is how to do it without ending up with a stack of unlabelled mystery tubs.
Pick soups that freeze well
Some soups are made for the freezer. Others change texture and need a little help.
Freeze beautifully:
- Lentil, split pea and bean soups
- Tomato soup, roasted pepper soup
- Squash, carrot and parsnip purées
- Chicken, beef or vegetable broths
- Minestrone-style soups, if you add the pasta later
Freeze with care:
- Cream and milk-based soups can separate. Freeze the base, then add the cream when you reheat.
- Potatoes turn grainy in chunky soups. Purée them in, or add fresh potatoes later.
- Pasta and rice go soft. Cook them fresh and add them to the reheated pot.
- Fresh herbs and lemon juice lose their lift. Add them at the end.
Make the batch
A good batch is 4 to 6 litres, which fills a large pot and gives you a handful of meals. Cook the soup a little more thickly than you would eat it, since you can thin it with stock when reheating and it takes up less freezer space.
Season lightly. Flavours often concentrate when reheated, and you can always add salt, pepper or acid at the table.
Cool it quickly and safely
This is the step people skip, and it matters. Hot soup left to cool slowly on the counter spends too long in the temperature range where bacteria grow.
- Do not put a full, steaming pot straight into the fridge.
- Divide the soup into shallow containers or wide bowls so it cools faster.
- Set the containers in a sink of cold water or ice water, stirring now and then.
- Once it is no longer steaming, move it to the fridge. Aim to have it fully chilled within a couple of hours of cooking.
- Freeze once it is cold.
Leave a bit of room at the top of each container, since liquid expands as it freezes. Glass jars need extra space and should be straight-sided, not shouldered, or they can crack.
Portion and label
Freeze in sizes you will actually use. Single servings (about 350 to 400 ml) suit lunches. Larger containers of about 1 litre feed two to three people at dinner. Freezer bags laid flat make thin slabs that stack neatly and thaw quickly.
Label every container with masking tape and a marker:
- Name of the soup
- Date it was made
- Any note, such as “add cream” or “add pasta”
If you do not label, you will find a tomato soup and a red lentil soup that look identical and taste nothing alike.
Use within a few months
For best flavour, most homemade soups are good for about three months in a standard freezer. They stay safe longer if kept constantly frozen, but they tend to lose quality. Keep a short list on the freezer door of what is in there, and cross off as you go.
Thaw and reheat
The safest way to thaw is in the fridge overnight. For a quick fix, put the sealed bag in a bowl of cold water, or heat gently from frozen in a pot with a splash of water to prevent sticking.
When reheating:
- Bring the soup to a steady simmer, so that it is steaming hot all the way through.
- Stir often, especially with thick purées, which can spit.
- Thin it with stock or water if it has thickened.
- Taste and adjust. A squeeze of lemon, a spoon of yoghurt, fresh herbs or a drizzle of good oil wakes up a thawed soup.
- Reheat only what you plan to eat. Do not refreeze soup that has been thawed and heated.
What can go wrong
- Grainy texture. Usually from dairy or potatoes. A quick blitz with a hand blender often fixes it.
- Watery soup. Simmer uncovered for a few minutes to reduce it.
- Bland flavour. Salt, acid and fresh herbs are the answer, not more spices.
- Freezer burn. Press out the air from bags, and use containers that close tightly.
A small habit for a long winter
Making one extra pot each time you cook soup is enough. In a month or two you will have a shelf of dinners waiting for you.
