How Long to Cook a Half Brisket

A half brisket is one section of a whole beef brisket, usually the leaner flat or the fattier point, cooked here low and slow with broth, onions, and simple seasonings. For a 4-pound (1.8 kg) piece, plan on about 4 hours in a covered 300°F (150°C) oven, then rest it before slicing; tenderness, not the clock alone, tells you when it is ready.

Ingredients

1 half brisket, about 4 lb (1.8 kg), flat or point cut
2 tsp kosher salt (about 12 g; use less if using fine table salt)
1 tsp coarsely ground black pepper (about 2 g)
1 tsp smoked paprika (about 2 g)
1 tbsp neutral cooking oil (15 ml), such as canola or vegetable oil
2 medium yellow onions, peeled and cut into thick wedges (about 300 g)
4 garlic cloves, lightly crushed (about 12 g)
2 cups low-sodium beef broth (475 ml)
2 tbsp tomato paste (30 g)
1 tbsp Worcestershire sauce (15 ml)
2 tsp apple cider vinegar (10 ml)
2 bay leaves
1 tsp dried thyme (about 1 g), or 3 small fresh thyme sprigs

Instructions

Trim and season the brisket. Pat the meat dry with paper towels. Trim away any hard surface fat and leave a layer about ¼ inch (6 mm) thick where possible; that thin cap helps protect the meat during the long cook. If the brisket has a very thin tail, tuck it under or tie the piece loosely with kitchen twine so it cooks more evenly. Combine the salt, pepper, and smoked paprika, then rub the mixture over all sides. Set the brisket aside while you prepare the other ingredients. This takes about 10 minutes of the 25-minute prep time.
Heat the oven and brown the meat. Set a rack in the middle of the oven and heat it to 300°F (150°C). Warm the oil in a heavy Dutch oven or other oven-safe pot with a tight-fitting lid over medium-high heat. When the oil shimmers, add the brisket and brown it for about 5–6 minutes on each broad side, then briefly brown the edges. Transfer it to a plate. Avoid crowding or moving it constantly; a deep brown surface adds savory flavor, but the meat does not need to cook through at this point.
Build the braising liquid. Lower the heat to medium. Add the onion wedges and cook for about 3 minutes, turning once, until their edges begin to color. Stir in the garlic and tomato paste and cook for 1 minute. Pour in the broth, Worcestershire sauce, and vinegar, scraping the browned bits from the bottom of the pot. Add the bay leaves and thyme. The liquid should come partway up the brisket when it is returned to the pot, not cover it completely.
Braise until tender. Put the brisket back in the pot, fatty side up if it has a fat cap. Cover tightly and place it in the oven for about 4 hours. Begin checking at 3 hours 30 minutes, but keep the lid on between checks so the pot does not lose heat and moisture. The timing is an estimate: a thinner flat may finish sooner, while a thicker or especially firm piece may need longer. If the liquid is at a vigorous boil, lower the oven temperature slightly; it should simmer gently. Add a little hot broth or water if the pot looks nearly dry.
Check both safety and tenderness. Insert an instant-read thermometer into the thickest part without touching the pot. USDA FSIS gives 145°F (63°C) with a 3-minute rest as the safe minimum for a whole cut of beef; for tender brisket, continue cooking well beyond that point, usually until it is around 195–205°F (91–96°C) and a probe or thin skewer slides in with little resistance. Temperature is a guide, and the easy probe test matters because brisket connective tissue softens at different rates. If it still feels tight, cover it and cook in 20-minute increments, checking again each time.
Rest, slice, and serve. Move the cooked brisket to a cutting board and tent it loosely with foil. Rest for 30 minutes so the juices settle. Meanwhile, skim excess fat from the pot juices and taste the liquid; remove the bay leaves and adjust salt and pepper if needed. Find the direction of the meat fibers and slice across them into slices about ¼ inch (6 mm) thick. For a point cut with very loose grain, cut it into manageable sections first, then slice each section across its own grain. Spoon warm onions and juices over the meat.

Tips

Use tenderness rather than a strict minutes-per-pound rule. Brisket shape, thickness, cut, pot fit, and oven accuracy all affect the finish time. A narrow 4-pound piece can cook faster than a thicker piece of the same weight. Start checking at the time in the recipe and allow extra time if the probe still meets resistance.
Choose the cut you prefer. The flat is leaner and gives neat slices; take care not to overcook it until it dries out. The point has more fat and connective tissue, so it is richer and may need a little longer. This method works for either, but do not assume two pieces of identical weight will finish together.
Make sensible swaps. Use low-sodium chicken broth if beef broth is unavailable; the flavor will be milder. If you do not have Worcestershire sauce, use an equal amount of soy sauce, knowing it will taste saltier and less tangy. Regular paprika can replace smoked paprika, but it will lack the gentle smoky note.
Keep the pot covered. A tight lid traps steam and prevents the braising liquid from evaporating too quickly. If your lid is loose, place a layer of foil over the pot before setting the lid on top. Do not add a large amount of extra liquid; braising is not the same as boiling the meat.

Serving Suggestions

Serve the sliced brisket with the softened onions and a ladle of the strained or unstrained cooking juices. Mashed potatoes, buttered egg noodles, rice, or roasted potatoes are good choices for catching the sauce. For a lighter plate, add green beans, roasted carrots, cabbage, or a crisp green salad. A soft roll can be used to make a sandwich with the meat and onions, especially if you reduce the pot juices briefly on the stovetop for a more concentrated spooning sauce.

If you are serving the brisket as part of a meal, slice only what you expect to eat right away and keep the rest in larger pieces with some cooking liquid. Larger pieces stay moister during storage and reheating than a full container of thin slices. Put the warm sides and brisket on the table separately so diners can choose how much sauce they want.

Variations

Red-wine braise: Replace ½ cup (120 ml) of the broth with dry red wine. After browning the onions, pour in the wine and scrape the pot; let it bubble for about 2 minutes before adding the remaining broth and other liquid ingredients. The sauce will have a deeper, slightly fruitier flavor.

Tomato and herb version: Add one 14½-ounce can (411 g) of diced tomatoes, drained, and use 1½ cups (355 ml) broth instead of 2 cups. Add ½ tsp dried oregano (about 0.5 g). This produces a more tomato-forward sauce and is especially good with potatoes or polenta.

Barbecue-style finish: Follow the recipe through the braise, then brush the rested brisket with 2–3 tbsp (30–45 g) of your preferred barbecue sauce. Broil briefly on a foil-lined tray until the glaze is bubbling, watching closely so the sugars do not burn. This adds a sticky surface while keeping the braised interior tender; it is a different finish from traditional smoked brisket, not a substitute for smoking flavor.

Slow cooker adaptation: Brown the meat and onions in a skillet, then transfer them with the remaining ingredients to a slow cooker. Cook on low until the brisket is probe-tender, commonly about 8–10 hours for a 4-pound piece, but use tenderness rather than time alone. Slow cookers vary, and the usual oven timing in this recipe does not transfer directly.

Storage and Reheating

Refrigerate brisket within 2 hours of cooking. Store it in a shallow, covered container with enough strained cooking liquid to moisten it; it keeps for 3–4 days in the refrigerator. For longer storage, freeze it with some of the liquid in a freezer-safe container for about 2–3 months for best quality. Thaw frozen brisket in the refrigerator rather than on the counter.

Reheat slices gently in a covered pan with a splash of broth or cooking juices over low heat, or warm them in a covered oven-safe dish at 300°F (150°C) until steaming throughout. Reheat leftovers to 165°F (74°C), checking the center with a food thermometer. Avoid prolonged high heat, which can make the lean flat dry. If reheating a large piece, allow more time than for individual slices and keep it covered.

Frequently Asked Questions

How long does a 4-pound half brisket take in the oven?
At 300°F (150°C), allow about 4 hours covered, plus 12 minutes for browning, about 5 minutes for the onions and aromatics, and 30 minutes to rest. The total in this recipe is about 5 hours 12 minutes including preparation. Begin checking early and add time in 20-minute increments if the meat is not probe-tender.

How long should I cook half a brisket per pound?
There is no dependable single minutes-per-pound figure because thickness and cut matter as much as weight. As a loose planning estimate, a covered brisket at 300°F (150°C) often takes around an hour per pound, but a broad, thin piece can finish sooner and a thick one can take longer. Use the thermometer and tenderness checks rather than relying on arithmetic alone.

Should half brisket be cooked covered or uncovered?
For this oven-braised method, keep it covered for most of the cooking so the meat stays in a moist environment and the liquid does not evaporate quickly. If you want a more browned or glazed surface, uncover it only near the end or use the barbecue-style broiler finish. An uncovered brisket for the entire cook is more likely to dry out in this recipe.

What internal temperature makes brisket tender?
The USDA FSIS safe minimum for a whole cut of beef is 145°F (63°C) followed by a 3-minute rest, but brisket is generally still tough at that temperature. For a braised brisket, a reading around 195–205°F (91–96°C) is common when the connective tissue has softened; confirm by checking that a probe slides into the thickest part with little resistance.

Can I cook a half brisket the day before serving?
Yes. Cool and refrigerate it promptly, within 2 hours, with the meat covered in some cooking liquid. The next day, remove any firm layer of fat from the chilled liquid if desired, then reheat the brisket covered until it reaches 165°F (74°C). It is easier to slice cold, but warm it gently after slicing so it does not dry out.

What if my half brisket is smaller or larger than 4 pounds?
A smaller piece may cook more quickly, but do not reduce the oven temperature; begin checking tenderness earlier. A larger or thicker piece may need additional time, so keep it covered and check every 20 minutes once it is near the expected finish. Scale the seasonings and braising liquid modestly, while ensuring the liquid comes partway up the meat in the pot.
