Frozen chicken breast is the backbone of a lot of freezers, and for good reason: it's convenient, great value in bulk, and it cooks just as well as fresh when you handle it properly. But people often buy frozen as if it were fresh, or fresh as if it were a chest freezer. This guide explains how our frozen chicken breast is packed and delivered, when to choose fresh or frozen, how to thaw it safely, and how to cook a frozen chicken breast.
Our frozen chicken breast packs
- 5kg Frozen Chicken Breast Fillets (£39.99): 5kg of frozen chicken breast fillets. According to the product page, it's available all week and typically dispatched within 2–3 working days.
- Misshaped Diced Chicken Breast 2kg (Previously Frozen) (£7.99): 2kg of skinless, boneless diced breast, previously frozen, with no added water, ready to portion.
If you'd rather have fresh, the Chicken Breast 1kg (£8.99) is a few dinners in the fridge, and the Fresh 5kg Chicken Breast Fillets (£19.99) is a bulk fresh bag to portion and freeze the day it lands.
How it's packed and delivered
Everything is packed at our butchery in Cornwall and delivered in a cold box. Frozen products may arrive at least partially defrosted after their journey; that's normal, and each product page says so. When your delivery arrives:
- Unpack straight away.
- Put anything you'll cook in the next day or so in the fridge.
- Refreeze or portion the rest. Check the product page, which states whether that item is suitable for refreezing.
Weekday delivery is free on orders over £85 and £6.95 under, with no minimum order.
Fresh or frozen chicken breast: which should you buy?
| Fresh | Frozen | |
|---|---|---|
| Best for | This week's dinners | Stocking up, meal prep |
| Shelf life | Use by the date on the pack | Months in the freezer |
| Price | Usually a little higher per kg | Usually lower per kg in bulk |
| Effort | Portion bulk fresh packs the day they arrive | Thaw what you need |
Quality isn't really the difference: cooked well, you'll struggle to tell them apart. Timing is. Match the pack to your week.
How to thaw frozen chicken breast safely
- In the fridge (best): on a plate or in a container on the bottom shelf, so juices can't drip onto other food. Individual breasts thaw overnight; a large block can take 24 hours or more.
- In cold water (faster): in a sealed bag, submerged in cold water, changing the water every 30 minutes. Cook it as soon as it's thawed.
- In the microwave: on the defrost setting, then cook immediately.
- Never on the worktop, where the outside can warm up while the inside is still frozen.
Once thawed, cook within 24 hours for the best quality. See buying chicken fillet in bulk for portioning tips.
How to cook a frozen chicken breast
We recommend thawing first, because it cooks more evenly and safely. If you do cook from frozen:
- Oven: bake at 200°C (180°C fan) for about 40–50% longer than a thawed breast, roughly 30–40 minutes, covered for the first half, until cooked through.
- In a sauce: simmer frozen diced chicken in a curry or casserole, stirring, until every piece is cooked through.
- Avoid: the slow cooker (it can keep frozen chicken in the danger zone too long) and frying whole frozen breasts, which burn outside before the middle is safe.
Whichever method, the FSA guidance is the same: chicken must be steaming hot throughout with no pink meat and clear juices. With a thermometer, 75°C in the thickest part.
Portioning a 5kg bag
If your 5kg bag arrives as a block, let it soften slightly in the fridge until you can separate the fillets, then:
- Bag them in portions (for example, 2 or 4 breasts).
- Squeeze out the air, label and date.
- Refreeze flat, if the product page confirms it's suitable.
Freezer burn and how to avoid it
Freezer burn shows as dry, pale or greyish patches on the surface. It isn't unsafe, but it makes the meat dry and tasteless in those spots. It happens when air reaches the chicken. To avoid it:
- Squeeze all the air out of freezer bags, or use a vacuum sealer.
- Wrap portions tightly before bagging.
- Keep your freezer at -18°C or below and don't leave the door open.
- Use older packs first: label and date everything so you can rotate.
If a breast has a little freezer burn, trim the affected area before cooking and use it in a sauce or curry.

Frozen chicken breast FAQs
Is frozen chicken breast as good as fresh?
Yes, if it's frozen and thawed properly. Thaw it in the fridge and pat it dry before cooking for the best results.
How long does frozen chicken breast take to thaw?
Overnight in the fridge for individual breasts, and 24 hours or more for a large block.
Can you cook chicken breast from frozen?
You can in the oven or in a sauce, allowing about 40–50% longer, but thawing first gives more even, reliable results.
Why does my frozen chicken arrive partly defrosted?
Frozen items travel in a cold box and may partially defrost in transit. That's normal; each product page explains what to do.
How long can you keep chicken breast in the freezer?
It's safe indefinitely at -18°C, but for best quality use it within about 6–9 months.
