Braised Brisket for Passover

Preheat oven to 325°F. Season both sides of brisket with salt and pepper. Place a roasting pan across 2 burners on medium-high. Heat 3 tablespoons oil in pan. Add brisket; sear until browned, 4 to 5 minutes per side. Transfer to a plate.

Reduce heat to medium. Add onion and minced garlic to pan; cook, stirring often, until onion is soft, about 4 minutes. (Add more oil to pan if needed.) Stir in tomato paste, and cook for 1 minute more. Stir in wine, and cook, scraping any browned bits from bottom of pan.

Add stock and bay leaves, and bring to a boil. Add brisket to pan, and cover with foil. Transfer to oven, and roast until meat is very tender, about 2 hours. Flip meat over. Add head of garlic. Cover, and roast for 30 minutes more.

Add remaining vegetables to brisket, cover, and roast until meat and vegetables are tender, about 1 hour.

Transfer vegetables and garlic to a platter and meat to a cutting board, reserving pan sauce. Tent meat with foil; let rest.

Let sauce stand in pan for 15 minutes, then skim fat from top. Place pan across 2 burners over medium-high heat; cook until sauce is reduced by slightly more than half, about 20 minutes. (You should have about 2 cups.) Stir in vinegar.

Thinly slice brisket against grain. Arrange slices on a platter with vegetables. Season with pepper, and drizzle with some sauce. Serve immediately with remaining sauce.
