4-5 pound grass fed beef brisket
1-2 Tbsp olive oil
3 large onions, sliced
5-6 garlic cloves, minced
1 sprig thyme
1 sprig rosemary
3-4 bay leaves
2 cups of beef stock
2-3 raw large carrots, peeled and cut into 1 1/2 inch pieces
Prepare the brisket for cooking. On one side of the brisket there should be a layer of fat, which you want.
If there are any large chunks of fat, cut them off and discard them. Large pieces of fat will not be able to render out completely. Using a sharp knife, score the fat in parallel lines, about 3/4-inch apart.
Slice through the fat, not the beef. Repeat in the opposite direction to make a cross-hatch pattern. Salt the brisket well and let it sit at room temperature for 30 minutes.
You’ll need an oven-proof, thick-bottomed pot with a cover, or Dutch oven, that is just wide enough to hold the brisket roast with a little room for the onions.
Pat the brisket dry and place it, fatty side down, into the pot and place it on medium high heat. Cook for 5-8 minutes, lightly sizzling, until the fat side is nicely browned.
(If the roast seems to be cooking too fast, turn the heat down to medium. You want a steady sizzle, not a raging sear.) Turn the brisket over and cook for a few minutes more to brown the other side.
When the brisket has browned, remove it from the pot and set aside. There should be a couple tablespoons of fat rendered in the pot, if not, add some olive oil. Add the chopped onions and increase the heat to high. Sprinkle a little salt on the onions. Sauté, stirring often, until the onions are lightly browned, 5-8 minutes. Stir in the garlic and cook 1-2 more minutes.
reheat the oven to 300°F. Use kitchen twine to tie together the bay leaves, rosemary and thyme. Move the onions and garlic to the sides of the pot and nestle the brisket inside.
Add the beef stock and the tied-up herbs. Bring the stock to a boil. Cover the pot, place the pot in the 300°F oven and cook for 3 hours. Carefully flip the brisket every hour so it cooks evenly.
After 3 hours, add the carrots. Cover the pot and cook for 1 hour more, or until the carrots are cooked through and the brisket is falling-apart tender.
When the brisket is falling-apart tender, take the pot out of the oven and remove the brisket to a cutting board. Cover it with foil. Pull out and discard the herbs.
At this point you have two options. You can serve as is, or you can make a sauce with the drippings and some of the onions.
If you serve as is, skip this step. To make a sauce, remove the carrots and half of the onions, set aside and cover them with foil. Pour the ingredients that are remaining into the pot into a blender, and purée until smooth.
If you want, add 1 tablespoon of mustard to the mix. Put into a small pot and keep warm.
Serve the brisket, sliced in 1/4-inch to 1/2-inch slices, against the grain of the meat, with the onions, carrots and gravy. Serve with mashed, roasted or boiled potatoes, egg noodles or polenta.
