Slow Cooked Beef Brisket: Oven, Smoker & Slow Cooker Guide

Quick answer: brisket rewards low-and-slow cooking. For an oven roast, cook at around 150–160°C until tender. For a smoker, hold around 110–120°C and cook until the brisket is probe-tender. For pulled or very soft brisket, the internal temperature is usually around 90–95°C, but tenderness matters more than the number alone.

Which cut should you use? For traditional oven cooking, our rolled brisket roasting joint is easy to handle. For smoking, choose a packer cut brisket. We also sell a flat cut brisket for slow roasting and braising.

How to Slow Roast Beef Brisket in the Oven

1. Take the brisket from the fridge and season generously with salt and black pepper.
2. Preheat the oven to 150–160°C.
3. Sear the brisket in a hot pan if you want extra colour and flavour.
4. Place it in a roasting dish with onions, carrots, garlic and a little beef stock.
5. Cover tightly with a lid or foil to retain moisture.
6. Cook slowly until the meat is tender enough to pull apart easily with a fork.
7. Rest for at least 20–30 minutes before slicing or pulling.

How Long Does Brisket Take in the Oven?

Cooking time depends on the size and shape of the joint, so use time as a guide rather than a finish line. A smaller rolled brisket may be tender in around 3–4 hours, while a larger joint can need considerably longer.

If the brisket still feels firm when pierced with a skewer or temperature probe, keep cooking. Properly slow-cooked brisket should feel soft and offer very little resistance.

Slow Roast Brisket Recipe

Ingredients

• 1 beef brisket joint
• Salt and black pepper
• 2 onions, roughly chopped
• 2 carrots, roughly chopped
• 3–4 garlic cloves
• 500ml beef stock
• Optional: a glass of red wine or dark ale

Method

2. Place the vegetables in the base of a roasting dish and sit the brisket on top.
3. Add the stock and optional wine or ale around the meat.
4. Cover tightly and cook at 150–160°C until tender.

6. Rest before slicing across the grain.

How to Smoke a Brisket Low and Slow

A full packer brisket is the classic BBQ choice because it includes both the flat and the fattier point.

1. Trim any very thick or hard external fat if necessary.
2. Season with a simple rub of salt, black pepper, garlic and paprika, or your favourite beef rub.
3. Set the smoker to around 110–120°C.
4. Cook slowly, maintaining a steady temperature.
5. Once the bark is well developed, you can wrap the brisket in butcher paper or foil if preferred.
6. Continue cooking until it is probe-tender, commonly around 90–95°C internal temperature.
7. Rest for at least 1 hour before slicing.

Can You Cook Brisket in a Slow Cooker?

Yes. A rolled or flat brisket works very well in a slow cooker. Brown the meat first if possible, then add onions, garlic and enough stock to create a moist cooking environment. Cook on low until the meat is tender enough to pull apart easily.

Should Brisket Be Sliced or Pulled?

That depends on the finish you want. For neat slices, cook until tender but still holding together. For pulled brisket, continue until the collagen has softened and the meat separates easily. Always slice brisket across the grain.

Brisket FAQs

What temperature should brisket be cooked to?

For a soft, pull-apart result, brisket is commonly ready around 90–95°C internally. Use tenderness as the final test because different joints can finish at slightly different temperatures.

Why is my brisket tough?

Brisket usually stays tough if it has not cooked long enough for the collagen to soften. Keep it covered and continue cooking gently until it becomes tender.

Does brisket have to be slow cooked?

Brisket is naturally rich in connective tissue, so slow cooking is the easiest way to produce a tender result.

What is the best brisket for smoking?

A full packer cut brisket is the traditional choice for smoking. It includes both the leaner flat and the fattier point.
