Smoky Braised Beef Brisket with Caramelized Onions

Brisket often gets a reputation for being dry because it’s a tough cut that requires long, low-temperature cooking to break down connective tissue and become tender. Without the right technique, that long cook can leave meat dry and chewy, despite generous sauces.

This method, inspired by a Cook’s Illustrated approach, solves that problem. The brisket is oven-braised in a sauce of wine, broth, and caramelized onions until very tender. After cooking, the brisket is chilled in its sauce so the meat can reabsorb liquid and stay moist.

The overnight soak plumps the slices and delivers a depth of flavor you won’t get from a quick saucing right before serving. It also makes the dish ideal for entertaining: most of the work is done the day before, leaving minimal prep on the day you serve it.

I grew up eating brisket at my grandmother’s house. Even when it was a bit dry, the smoky flavor always won me over — she used liquid smoke. In this recipe I add a couple teaspoons of liquid smoke along with smoked paprika and a touch of tomato paste for rich, smoky, umami notes that nod to that childhood flavor.

Ingredient notes

• 3–4 lb flat cut brisket: Use the flat (not the point) for uniform slices and even cooking. The flat is leaner and holds together well for braising and slicing.
• Seasoning: Salt, pepper, brown sugar, smoked paprika, crushed red pepper, liquid smoke (or substitutes listed below), fresh thyme and parsley, plus a splash of cider vinegar to brighten the sauce.
• Tomato paste: Adds umami and depth. Tomato paste from a tube is convenient because you can use only what you need.
• Broth: Chicken or vegetable broth works fine. Use a good-quality base for best flavor.
• Dry red wine: Choose a wine you’d enjoy drinking — a poor-quality wine will negatively affect the sauce, so omit it rather than use something unpleasant.

Additions and substitutions

• Liquid smoke alternatives: Use smoked salt, extra smoked paprika, or a little chipotle powder or peppers for smoky flavor (chipotle adds heat). Worcestershire sauce can also add depth, but you may want to reduce the brown sugar if you use it.
• Instead of wine: Replace wine with more broth if you prefer to skip alcohol.
• Onion varieties: Yellow onions are recommended for their balanced flavor, but any onion will work since they cook down for a long time.

Step-by-step photos and instructions

Line a 9×11-inch baking dish with two sheets of foil placed perpendicular so the ends hang several inches over the sides. After placing the brisket, you’ll use the overhang to fold the foil over and enclose the meat.

Halve the onions, remove skins, and slice crosswise into roughly ¼-inch slices.

Pat the brisket dry with paper towels.

Poke a few holes through the fat into the meat with a fork to help flavors penetrate.

Season both sides generously with salt and pepper.

Sear the brisket in hot oil until a light brown crust forms on both sides, then transfer to a plate.

Remove excess fat from the pan if needed. Lower heat to medium, add the onions, brown sugar, and a pinch of salt, and cook until soft and golden, about 10 minutes.

Add garlic, tomato paste, smoked paprika, and crushed red pepper and cook, stirring, for a couple of minutes.

Stir in the flour and cook for two minutes to remove the raw flour taste.

Slowly add the wine, then the broth and liquid smoke. Bring to a boil, scraping up brown bits, and simmer until the liquid thickens slightly.

Add thyme to the sauce, pour it into the foil-lined dish, and nestle the brisket fat-side up into the sauce.

Fold the foil over the brisket to enclose it, and bake at 300°F (148°C) for about 3–3½ hours, until a fork slides in with little resistance.

Remove the pan from the oven, carefully open the foil, and let the brisket cool at room temperature for about 30 minutes.

Lift the brisket from the pan and strain the sauce into a bowl. Remove thyme stems and place the cooked onions in a covered container in the refrigerator.

Remove the foil liner and return the brisket to the baking dish. Pour the sauce over the meat, cover, and refrigerate for at least 12 hours (up to 3 days).

About 45 minutes before serving, preheat the oven to 375°F (190°C). Skim hardened fat from the sauce surface and warm the sauce in a saucepan. Add cider vinegar and the reserved onions, then taste for seasoning.

Slice the brisket about ½-inch thick, place the slices back in the baking dish, and pour the warmed sauce over them.

Cover loosely with foil and bake for about 25 minutes until heated through. Garnish with chopped parsley and serve.

Serving suggestions

My favorite sides for this brisket are buttermilk whipped potatoes and brown-buttered carrots — both pair beautifully with the rich, savory sauce. Warm dinner rolls or flaky buttermilk biscuits are also excellent on the table.
