Curing bacon at home takes about a week from start to first rasher, and almost all of that time is the fridge quietly doing the work while you get on with your life. The active part, rubbing the cure into a piece of pork belly, takes about ten minutes, and everything after that is waiting, rinsing and a few days of air drying.
What follows is what happens on each of those days, why the timing changes with the joint you have chosen, and how to tell whether your bacon has had enough time or too much.
How long does dry curing actually take?
Dry curing is a two-stage clock. First the cure sits on the meat in the fridge for the number of days given in your recipe booklet, drawing moisture out and preserving the pork. Then, after a rinse, the bacon air dries in the fridge for a few days, which firms the texture and concentrates the flavour. Add the two together and you are looking at roughly a week.
Follow the booklet timings rather than guessing, because the quantities and the days are matched to each other. Our Bacon Making Kit uses a traditional dry cure of salt and sugar with sodium nitrite (E250) and sodium nitrate (E251), which is what protects the meat while it cures, and three seasonings to flavour it, chilli and garlic, juniper and fennel, or pancetta. No smoker, no special equipment, and no cellar required.
It is worth saying plainly why home curing is worth a week of patience. Most supermarket bacon is wet cured and pumped with water, which is why it leaks and shrinks in the pan. Dry cured bacon is firmer, more flavourful and behaves itself over the heat.
What happens on each day of the cure?
The days look like this, whatever the exact numbers in your booklet say.
- Day one: the rub. The cure goes on, rubbed evenly over every surface of the pork belly, including the edges and any awkward folds. Even coverage matters more than force. Then it goes into the fridge, and the salt immediately begins pulling moisture out of the meat.
- The middle days: the fridge does the work. Liquid draws out of the pork and pools around it. This is exactly what should happen, and it is the sign the cure is working. The meat firms up noticeably over these days and its colour deepens.
- The last curing day: the check. By the end of the curing period the belly should feel distinctly firmer than the floppy raw joint you started with, with the thickest part no longer soft and yielding.
- Rinse day. Rinse the excess cure off thoroughly under cold water and pat the bacon completely dry. Rinsing is not optional tidying: it is how you control the saltiness of the finished bacon.
- Air drying: a few days. The rinsed joint hangs in the fridge to dry. Our trick is to hang it from the top shelf so it dangles into the door area where the tall bottles usually live, which tends to be the one spot with room to spare.
- Slicing day. By now the outside is dry to the touch and the joint is firm enough to slice cleanly. A sharp kitchen knife is all it takes.
Why does the timing depend on the joint?
Because curing works inwards from the surface, and thickness decides how far the salt has to travel. That is the whole reason our recipes use pork belly. Streaky bacon is pork belly and back bacon is pork loin, and belly is the thinner of the two, so it cures faster and more reliably in a domestic fridge.
You can make back bacon with the same cure and recipe using a 500g pork loin joint with the skin removed, and plenty of people do. Just accept that a thicker, denser joint is less forgiving than a belly, and follow the booklet rather than your instincts.
One small bonus if you trim skin off your belly: do not bin it. Toss bite-size pieces with salt and a splash of vinegar and roast them on a wire rack in a hot oven until puffed and crisp. Pork scratchings are the perfect thing to snack on while your bacon cures.
What if you cure it for too long, or not long enough?
Both are fixable, and both have a clear signature.
Too long, and the bacon comes out too salty. Rinse it more thoroughly after curing, and soak it in cold water for an hour to draw out the excess salt before it goes off to dry. Next time, do not exceed the curing time in the booklet.
Not long enough, and the bacon stays wet and floppy. Give it more time in the fridge so more moisture is drawn out, and check that the cure was rubbed in evenly, since a patch that missed the cure is a patch that never firmed up. Undercured bacon is the more common of the two problems, mostly because people are impatient, which is understandable when the house already smells of the idea of bacon.
Is home-cured bacon safe on this timescale?
Yes, when you follow the cure quantities and timings, use fresh pork, keep it refrigerated throughout and cook it before eating. The cure is what preserves the meat, so never reduce it to make the bacon less salty. If you want milder bacon, rinse and soak more thoroughly at the end instead, which changes the salt without changing the protection.
Store the finished bacon in the fridge and use it within the timeframe in the booklet, or freeze it. If you are freezing, slice it or cut it into lardons first and spread the pieces on a baking sheet to freeze before bagging them up, because freezing the joint whole means defrosting the whole thing every time you fancy a sandwich. And always cook it through before eating: dry cured bacon is preserved, not cooked.
Then comes the good bit. Because it is dry cured, it crisps up beautifully without leaking water or shrinking the way shop bacon does, and the first sandwich made from a joint you cured yourself is a genuinely smug moment. Everything except the pork is in the bacon kit, which is gluten free and lactose free, and hand-packed in Britain.
Bacon curing time FAQs
How long does bacon take to cure in the fridge?
Follow the days given in your recipe booklet for the curing stage, then allow a few more days of air drying afterwards. In total, expect around a week from raw belly to sliceable bacon.
Can you cure bacon for too long?
Yes, and the result is bacon that tastes too salty rather than bacon that is unsafe. Rinse it more thoroughly and soak it in cold water for an hour, and stick to the booklet timings next time.
Do you have to air dry bacon after curing?
It is the stage that firms the texture and concentrates the flavour, so we would not skip it. A few days hanging in the fridge makes the bacon noticeably better and much easier to slice thinly.
How do you know when bacon has finished curing?
It feels firm rather than floppy, especially at the thickest point, and it has visibly given up liquid. If it still feels wet and soft, it needs longer.
Does home-cured bacon need nitrites?
Our cure includes them, because they are what protect the meat while it cures and it is the safest, most reliable way to cure bacon at home. Our jerky and biltong kits use no cure at all, just seasonings.
