• 4 large organic carrots, peeled and cut into 2-inch chunks
• 3 stalks organic celery, cut into 2-inch chunks
• 8 cloves garlic, smashed
• 0.33 cup organic tomato paste
• 2.5 cups rich organic beef bone broth
• 3 tbsp organic coconut aminos
• 2 tbsp raw unfiltered apple cider vinegar or red wine vinegar

Step-by-Step Instructions

1. Season the Brisket: In a small bowl, mix smoked paprika, garlic powder, onion powder, dried oregano, coarse sea salt, and black pepper. Rub the seasoning paste firmly into all sides and crevices of the beef brisket.
2. Hard Cast-Iron Sear (Maillard Flavor Invariant): Heat 2 tbsp beef tallow (or ghee) in a large 6-quart to 8-quart enameled cast-iron Dutch oven over MEDIUM-HIGH heat. Sear the brisket fat-cap side DOWN first for 5 to 6 minutes until a deep, dark caramelized crust forms. Flip and sear the other side for 4 minutes. Transfer seared brisket to a large platter.
3. Caramelize the Onions: Reduce heat to MEDIUM. Add sliced yellow onions to the hot rendered beef drippings. Cook for 8 to 10 minutes, stirring occasionally, until deeply golden-brown and sweet. Add smashed garlic cloves and tomato paste; stir constantly for 2 minutes to caramelize the tomato paste.
4. Deglaze the Pot: Pour in the vinegar, coconut aminos, and beef bone broth. Use a wooden spatula to scrape up every bit of browned beef fond stuck to the bottom of the Dutch oven. Stir until the braising liquid is smooth and fragrant.
5. Assemble & Slow Braise: Scatter carrots and celery into the pot. Nestle the seared brisket fat-side UP directly on top of the bed of caramelized onions and vegetables. Tuck fresh rosemary sprigs, thyme sprigs, and bay leaves into the liquid around the beef. (Liquid should reach roughly halfway up the sides of the brisket).
6. Bake to Melting Tenderness: Cover tightly with the heavy Dutch oven lid (or double layer of foil). Transfer to a preheated 300°F (150°C) oven. Braise undisturbed for 3 to 3.5 hours (or slow cook on LOW for 8 hours) until the brisket is fork-tender and yields with zero resistance.
7. Rest, Slice & Serve: Transfer brisket to a carving board and tent loosely with foil for 15 minutes. Slice across the grain into 0.25-inch thick slices. Skim excess fat from the pan juices if desired, discarding bay leaves and herb stems. Arrange brisket slices over a platter with tender carrots and ladles of rich caramelized onion gravy. Serve immediately!
