Braised Oven Brisket with Onion Gravy
Not rated yet. Be the first.
Make it the day before and you get to sit down with everyone else. We brown it hard, braise it covered with onions and wine, then slice it cold and warm it in its own gravy.
The short version
Brown a 4-pound brisket flat, cook down onions with tomato paste and wine, cover and braise at 325°F for about 3½ hours until fork-tender. Rest, slice against the grain and serve with the reduced pan sauce. Best made a day ahead.
What makes ours better
what we fixed so you don’t have to
-
Brown it hard first. A dark crust on both sides builds the deep beefy flavor that the whole braise is built on. Don't rush it.
-
Cook the tomato paste with the onions. Letting the paste darken for a minute turns it from raw and tinny to sweet and savory, and it thickens the gravy.
-
Slice it cold, reheat it in the sauce. Cold brisket slices cleanly across the grain instead of shredding, and it soaks up the gravy as it warms. It also means no stress on serving day.

Steps
nobody opens the oven door. looking at you, Dad.
-
Heat the oven, season the meat
Set a rack in the lower third of the oven and heat it to 325°F. Pat the brisket dry and rub the salt and pepper all over it.
-
Brown both sides
Heat the oil in a large Dutch oven or heavy roasting pan over medium-high heat. Brown the brisket for 5 to 6 minutes per side until deep brown, working in the pan it fits in. Move it to a plate.
If the pot smokes hard, lower the heat. Burnt bits will turn the gravy bitter.
About 12 min. Cook mode has a timer for this step.
-
Cook the vegetables
Reduce the heat to medium. Add the onions, carrots and celery, scraping up the browned bits, and cook, stirring often, 10 to 12 minutes until soft and golden. Stir in the garlic and tomato paste and cook 1 minute, until the paste darkens a shade.

-
Add the liquids
Pour in the wine and simmer 2 minutes, scraping the bottom. Add the broth, Worcestershire, vinegar, brown sugar, thyme and bay leaves, and bring to a simmer.
-
Cover and braise
Set the brisket back in the pot, fat side up, with the onions around it. The liquid should come about halfway up the meat. Cover tightly (foil under the lid helps) and braise for 3 to 3½ hours, until a fork twists in with almost no resistance.
Don't peek too often. Every lid lift lets out the steam that is tenderizing the meat.

-
Cool in the sauce
Take the pot from the oven and let the brisket sit in the liquid for 30 minutes. For the best slices, cool completely, then chill overnight in the pot.

-
Slice against the grain
Lift the brisket onto a board. Find the direction the muscle fibers run and slice across them, about ¼ inch thick. Skim the fat from the sauce, discard the thyme stems and bay leaves, and boil the sauce 10 minutes or so, reducing it by about a quarter, until it coats a spoon. Taste and add salt.
-
Warm and serve
Slide the slices back into the sauce, cover, and warm on the stove or in a 350°F oven for 20 to 25 minutes until hot through. Serve with plenty of sauce.

Good to know
the stuff I’d tell you over the phone
- A flat ("first cut") is leaner and slices neatly. The point ("second cut") is fattier and more forgiving; use a 4-pound point and expect the same time.
- The fat cap keeps the meat moist. Trim it to about ¼ inch rather than all the way off.
- Serve over mashed potatoes or egg noodles to catch the gravy, with carrots and roasted potatoes added to the pot for the last hour if you like.
- Storage. Fridge, sliced in the sauce, 5 days. Freezer, 3 months. Reheat covered in a 325°F oven until hot through.
Questions, answered
the questions my cousins text me
How long does brisket take in the oven?
About 3 to 3½ hours at 325°F for a 4-pound flat. It's done when a fork twists in easily; it should reach roughly 200°F inside. A bigger or thicker piece takes longer.
Should I cover brisket in the oven?
Yes. A braise needs a tight cover to trap steam and keep the meat from drying out. Use a lid, and put foil under it if the lid doesn't fit snugly.
Why is my brisket tough?
Almost always it needs more time, not less. Brisket is tough until the collagen melts. Cover it again and give it another 30 minutes. Slicing with the grain also makes it chewy.
Can I make brisket the day before?
Yes, and you should. Chill it in the sauce overnight, slice it cold, and reheat in the sauce. It's easier to slice and the flavor deepens.
How do I slice against the grain?
Look for the lines running through the meat and cut perpendicular to them. A brisket's grain can change direction, so you may need to turn the piece halfway through.
