Slow-Cooked Brisket with Onion Gravy
Why this recipe works
- Deep savoury base: Browning the brisket and softening the onions before slow-cooking builds a richer gravy with more depth than simply adding everything raw.
- Classic comfort pairing: Tender sliced beef, onion gravy, mashed potatoes and carrots give the dish a familiar, satisfying Sunday-dinner feel.
- Good for planning ahead: Brisket reheats well in its gravy, which helps keep the slices moist and makes leftovers practical for another meal.

Timing notes
- Rest before slicing: Let the brisket rest for the full 10 minutes so the meat firms slightly and slices more neatly.
- Finish the gravy last: Reduce the strained cooking liquid shortly before serving so the gravy stays glossy and hot.
Texture tips
- Slice across the grain: Cutting the brisket across the grain shortens the meat fibres and makes each slice easier to eat.
- Adjust the gravy: If the gravy becomes too thick, loosen it with a splash of hot water and warm it gently until smooth.
Make-ahead tips
- Reheat in the gravy: Warm the sliced brisket gently in the onion gravy to help prevent the meat from drying out.
- Freeze with the sauce: Freeze the brisket and gravy together for best texture, then defrost overnight in the fridge before reheating.
Ingredient notes
- Choose brisket for slow cooking: Brisket has enough connective tissue to become tender and flavourful during a long, gentle cook.
- Fresh or dried thyme: Fresh thyme gives a softer herbal note, while dried thyme is more concentrated and should be added with the bay leaves.

Ingredients
Brisket and gravy
Mash and carrots
Instructions
- Heat the vegetable oil in a large frying pan over medium-high heat. Season the brisket all over with the black pepper, then brown well on all sides, 8 to 10 minutes in total.
- Thinly slice the onions. Add them to the pan and cook over medium heat until softened and lightly golden, 8 to 10 minutes, scraping up any browned bits.
- Sprinkle over the plain flour and cook for 1 minute, stirring so it coats the onions. Gradually whisk in the beef stock until smooth, then stir in the Worcestershire sauce.
- Pour the onion and stock mixture into the slow cooker, then add the bay leaves and thyme. Nestle in the brisket, cover, and cook on low for 3 hours, or until the meat is very tender when pierced.
- About 35 minutes before serving, peel the potatoes and cut into even chunks. Put into a saucepan, cover with water, bring to the boil, then simmer until tender, 18 to 20 minutes.
- Peel the carrots and cut into thick batons. Simmer in a saucepan of water until tender, 10 to 12 minutes, then drain and keep warm.
- Lift the brisket onto a board and rest for 10 minutes. Strain the cooking liquid into a saucepan, pressing the onions to extract their flavour, then simmer for 5 to 8 minutes until glossy and lightly thickened; discard the bay leaves and thyme sprigs.
- Drain the potatoes and mash until smooth. Slice the brisket across the grain and serve with the onion gravy, mashed potatoes, and carrots.
Recipe notes
Tips
- For the neatest slices, rest the brisket for the full 10 minutes, then cut across the grain with a sharp knife.
- If the gravy is thicker than you like, whisk in a splash of hot water and warm through gently.
- If serving anyone who is pregnant, elderly, or immunocompromised, make sure the brisket is cooked until piping hot throughout and the gravy is simmered thoroughly before serving.
Substitutions
- Replace Beef stock with chicken stock for a lighter gravy.
- Replace Fresh thyme with 1 tsp dried thyme, added with the bay leaves.
- Replace Plain flour with cornflour: mix 2 tbsp cornflour with 2 tbsp cold water, then whisk into the simmering cooking juices until thickened.
Storage
- Refrigerate up to 3 days
- Cool brisket and gravy quickly, then refrigerate in a sealed container. Reheat brisket slices in the gravy in a saucepan over low heat until piping hot; add a splash of water if needed. Freeze brisket and gravy together for best results; defrost overnight in the fridge before reheating.
