This sliced beef brisket is slow-roasted with onions, garlic, broth, and a smoky spice rub until the connective tissue softens and every slice is tender. The covered oven method is dependable and produces its own rich pan gravy.
The two details that matter most happen after cooking: rest the brisket long enough for the juices to settle, then slice across the grain. Those steps turn a tough cut into neat, juicy slices.

Tender Oven-Roasted Sliced Beef Brisket
Ingredients
Instructions
- Heat the oven to 300°F. Pat the brisket dry. Combine the salt, pepper, paprika, garlic powder, onion powder, and thyme, then rub the seasoning over every side.
- Heat the oil in a large Dutch oven or roasting pan over medium-high heat. Brown the brisket for 4 to 5 minutes per side, then transfer it to a plate.
- Spread the onions and garlic in the pan. Whisk together the broth, Worcestershire sauce, tomato paste, and optional brown sugar; pour the mixture around the onions.
- Return the brisket fat-side up. Cover tightly and roast for 4 to 5 hours, until a thermometer or skewer slides into the thickest part with little resistance, generally around 195 to 205°F.
- Transfer the brisket to a board, tent loosely with foil, and rest for 30 to 45 minutes. Skim excess fat from the pan juices and simmer the liquid until lightly thickened.
- Identify the direction of the grain and slice the brisket across it into 1/4-inch slices. Spoon the onion gravy over the meat and serve.

Flat Cut or Point Cut?
The flat is leaner, evenly shaped, and easiest to slice for a platter or sandwiches. The point has more internal fat and a richer flavor but tends to pull apart rather than form uniform slices. A whole packer brisket contains both muscles and may take considerably longer to cook.
How to Prepare Brisket for Slicing
Trim hard exterior fat and leave an even ¼-inch cap to protect the meat. Before seasoning, notice which direction the grain runs; after roasting, the bark can make it harder to see. You can cut a small corner perpendicular to the grain as a reminder.
Brisket Temperature: Safe Versus Tender
USDA guidance sets 145°F with a 3-minute rest as the minimum safe temperature for whole beef roasts. Brisket, however, remains chewy at that point. For a sliceable but tender texture, continue slow cooking until roughly 195–205°F and, more importantly, until a probe enters with very little resistance.
Why Brisket Can Turn Out Tough
- It was removed before the collagen had enough time to soften.
- The pan was not sealed tightly and lost too much moisture.
- The oven temperature was too high, tightening the meat before it tenderized.
- The brisket was sliced with the grain instead of across it.
- It was cut immediately instead of resting.
How to Slice Beef Brisket
Use a long, sharp slicing knife. Position the brisket so the visible muscle fibers run left to right, then cut straight down from front to back so each slice shortens those fibers. Aim for ¼-inch slices for a tender flat; make them slightly thicker if the meat is beginning to crumble.
Make-Ahead Brisket
Brisket often tastes even better the next day. Cool it in the cooking liquid, refrigerate overnight, remove the solidified fat, and slice the cold meat. Arrange the slices in a baking dish with the strained liquid, cover, and reheat at 325°F until hot.
Serving Ideas
Serve sliced brisket with mashed potatoes, roasted carrots, green beans, coleslaw, macaroni and cheese, pickles, or crusty rolls. Leftover slices make excellent sandwiches, tacos, hash, or noodle bowls.
Storage and Reheating
Refrigerate brisket with some of its juices in an airtight container for up to 4 days. Reheat covered at 300–325°F or very gently on the stovetop. Freeze sliced brisket in gravy for up to 3 months and thaw overnight in the refrigerator.
Frequently Asked Questions
How much brisket should I buy per person?
Plan on about ½ pound of raw boneless brisket per adult. The meat loses substantial weight as fat and moisture render during cooking.
Should brisket be sliced hot or cold?
For immediate serving, slice it warm after a 30–45 minute rest. For the neatest make-ahead slices, chill it in the cooking liquid and cut it cold before reheating.
Why did my brisket fall apart?
It likely cooked beyond the ideal point for slicing or was cut too thin while very hot. Thicker slices and a longer rest help it hold together.
Can I use a slow cooker?
Yes. Cook the seasoned brisket with the onion mixture on low for 8–10 hours, or until probe-tender. Rest it before slicing across the grain.
