This Slow Cooker Brisket turns a tough cut into melt-in-your-mouth tender slices with a rich miso and onion gravy. It takes about 15 minutes of prep – sear the beef and layer everything in the crock pot – then 5 to 6 hours on HIGH does the rest.

Beef brisket in a slow cooker is maybe the reason to own one. The beef cooks low and slow until it practically falls apart, with next to no effort from you.
What I love about this recipe – apart from how easy it is – is that the whole family loves it, fussy kids included. Fish sauce and a spoonful of miso give the gravy a deep, savory flavor without anyone guessing what is in it.
My husband and I serve it over cauliflower mash to keep it keto, while the kids eat theirs with mashed potatoes. I call that a win!
Why You’ll Love This Recipe
- Minimal hands-on time: about 15 minutes of searing and layering, then the slow cooker takes over.
- Tender but sliceable: cooked just long enough to slice neatly – or a little longer if you would rather shred it.
- Gravy built in: the onions and cooking juices turn into a rich, savory gravy with no flour needed.
- Low carb and gluten free: naturally keto friendly and dairy free too.
- Family friendly: serve it with mashed potatoes for the kids and cauliflower mash for the grown-ups.
Here’s What You’ll Need
You will need a 6-quart (5.7-liter) or larger slow cooker and a Dutch oven (casserole dish) or large skillet for searing. An instant-read thermometer takes the guesswork out of doneness, and an immersion blender is handy if you like a smooth gravy.
- Beef brisket: flat cut brisket is leaner and slices neatly. In the UK it is usually sold rolled and tied – remove the string before cooking.
- Avocado oil: or any neutral oil with a high smoke point, for searing.
- Fish sauce: adds savory depth without tasting fishy. Worcestershire sauce works too.
- White wine: for a little acidity to balance the rich beef.
- Chicken or beef broth: you only need a little – the brisket releases plenty of juices as it cooks.
- White miso paste: a small spoonful gives the gravy a big umami boost.
- Onions and garlic: they melt down and become the base of the gravy.
- Carrot, leek and celery: tied into a bundle with the herbs so they are easy to lift out at the end.
- Herbs: bay leaves, a rosemary sprig and parsley stalks to flavor the cooking liquid, plus chopped fresh parsley to serve.
Know your cut
Flat or point: which brisket to buy
Brisket comes from the lower chest of the cow, just behind the front legs, and it goes by the same name in the US and the UK. Brisket is made up of two muscles: the leaner flat (first) cut, which slices neatly and is what I use here, and the fattier point (deckle), which is better for shredding. It is a hard-working muscle full of connective tissue so it needs long, slow cooking to turn tender.
How to Make Brisket in the Slow Cooker
↓ For the full ingredients and detailed method, jump to the recipe card.
- Season the brisket with salt and pepper on both sides. Heat the oil in a large Dutch oven (casserole dish), add the brisket and sear for a few minutes on each side until nicely browned. You may need to cut your brisket in half if it is particularly big!
- Add the fish sauce, white wine, chicken or beef broth and miso paste to the slow cooker. Stir with a wooden spoon to dissolve the paste.
- Add the sliced onions, garlic, salt, pepper and bay leaves. Tie the leek, carrot, celery, rosemary sprig and parsley stalks together and add them to the crock pot – they will flavor the gravy.
- Place the brisket over the onions, fat side up. Cover and cook on HIGH for 5 to 6 hours (or LOW for 8 to 10 hours) without opening the lid. The brisket is ready when the edges fall apart when prodded with a fork but the middle still holds together. Cook it for longer and it won’t slice neatly – but you can shred it instead.
- Lift the brisket onto a cutting board. Slice against the grain and keep warm.
- Strain the juices in the slow cooker and discard the solids. Bring to a boil in a saucepan and simmer for 10 to 15 minutes until slightly reduced. Alternatively, discard the tied vegetables and bay leaves and blend the onions and cooking liquid with an immersion blender – no need to reduce. Taste and adjust the seasoning, if needed.
- Arrange the brisket on a platter, drizzle with the gravy and garnish with chopped parsley.
How to Tell When Brisket Is Done
Slow cookers vary, so go by feel rather than the clock. A fork should slide into the brisket with little resistance, and an instant-read thermometer should read around 200°F (93°C) in the thickest part. If it still feels tough, it needs more time, not less – put the lid back on and check again every 30 to 45 minutes.
Cook’s tip
Always slice against the grain
Look for the lines of muscle fiber running along the brisket and slice across them, about ¼ inch (5mm) thick. Slicing with the grain gives you chewy, stringy pieces, even when the beef is perfectly tender.
Serving Suggestions
Sliced brisket and gravy needs something to soak up all those juices.
- Mashed potatoes: my Slow Cooker Mashed Potatoes are completely hands-off, or try buttery Colcannon.
- Cauliflower mash: to keep it low carb, the way we eat it at home.
- Green vegetables: crisp Air Fryer Green Beans or steamed broccoli.
- Sunday roast style: add Air Fryer Yorkshire Puddings and plenty of gravy.

Storage and Reheating
- Fridge: cool, then store the sliced brisket in its gravy in an airtight container for up to 4 days.
- Reheat: warm gently in a covered pan on the stove, or in the oven at 325°F (160°C) covered with foil, until piping hot. Keeping the slices in the gravy stops them drying out.
- Freeze: freeze the slices in gravy for up to 3 months, then thaw overnight in the fridge before reheating.
- Leftovers: use them in sandwiches, pasta bakes or soup.

Notes
- Slice against the grain: cut across the muscle fibers, about ¼ inch (5mm) thick, for the most tender slices.
- Go by feel, not the clock: slow cookers vary, so the brisket is ready when a fork slides in easily – around 200°F (93°C) in the thickest part. If it still feels tough, give it longer.
- No wine: replace it with the same amount of beef broth, or use red wine instead of white.
- No fish sauce: Worcestershire sauce works well instead.
- No miso: you can leave it out – the gravy will just be a little less rich.
- Shredded brisket: cook for an extra hour or two, then shred with two forks and toss in the gravy.
- Oven or Instant Pot: try my Oven Braised Brisket or Instant Pot Brisket.
- Keto: the recipe is naturally low carb and gluten free – just check the labels on your fish sauce and broth.
- Slimming friendly tip: use low-calorie cooking spray instead of oil for searing.

Frequently Asked Questions
Both work. This recipe uses HIGH for 5 to 6 hours, which gives tender brisket that still slices neatly. On LOW, allow 8 to 10 hours. Try not to lift the lid, as every peek lets heat escape and adds to the cooking time.
It is not essential, but searing gives the beef a deeper, roasted flavor and adds color to the gravy. If you are short on time you can skip it and put the brisket straight into the slow cooker.
Tough brisket is almost always undercooked – the connective tissue needs time to melt. Put the lid back on and check every 30 to 45 minutes until a fork slides in easily. Slicing against the grain also makes a big difference.
No. You only need a small amount of liquid because the brisket and onions release plenty of juices as they cook, and those juices become the gravy.
No – thaw it in the fridge first. Frozen meat takes too long to reach a safe temperature in a slow cooker.
Yes, and it tastes even better the next day. Slice the cooked brisket, refrigerate it in the gravy for up to 4 days, then reheat gently until piping hot.
Troubleshooting
| Problem | Cause | Fix |
|---|---|---|
| Brisket is tough | Not cooked long enough | Cook longer, checking every 30 to 45 minutes until a fork slides in easily |
| Brisket falls apart when sliced | Cooked a little too long | Shred it with two forks and toss it in the gravy instead – perfect for sandwiches |
| Slices are chewy and stringy | Sliced with the grain | Slice across the grain, about ¼ inch (5mm) thick |
| Gravy is thin | The beef released lots of juices | Simmer to reduce for 10 to 15 minutes, or blend the onions into the liquid |
| Gravy is too salty | Fish sauce, miso and broth all add salt | Use low-sodium broth and taste before adding the extra salt |
| Leftovers dry out when reheated | Reheated without liquid | Reheat the slices in the gravy, covered |
