Before you start

Before starting, ensure the oven is fully preheated to 300°F (150°C). Prepare the workstation by clearing enough space to handle a large piece of meat and the baking dish. Have all ingredients measured and ready to go.

Remove the brisket from the refrigerator 30 minutes before cooking to bring it closer to room temperature, which helps the meat cook more uniformly throughout. Keep the sink and workspace clean, and be prepared to wash your hands thoroughly after handling the raw beef to maintain proper kitchen hygiene.

Ingredients at a glance (3)
  • 3 lb beef brisket, trimmed of excess fat
  • 1/2 cup unsalted butter, softened
  • 6 cloves garlic, minced

Instructions

Preparation

  1. Prepare the brisket
    Preheat the oven to 300°F (150°C). Pat the beef brisket dry with paper towels to ensure better preparation. Place the brisket into a large oval baking dish, ensuring it fits snugly without overcrowding.
    Look for The meat should be sitting flat in the dish.
    Tip Room temperature meat cooks more evenly, so take the brisket out of the refrigerator 30 minutes before cooking.

At the end of this phase, the brisket should be placed in the baking dish, looking ready for the butter. Ensure the meat is sitting flat in the baking dish and that you have a clean workspace before moving on to the butter application.

Applying Garlic Butter

  1. Prepare and add garlic butter
    In a small bowl, combine the softened butter and minced garlic until thoroughly mixed. Spread the garlic butter mixture generously over the top of the brisket. Cover the baking dish tightly with aluminum foil to trap moisture, which is essential for breaking down the connective tissue and ensuring the meat becomes tender during the long cooking process.
    Look for The butter should be spread in an even layer across the entire surface of the brisket.
    Tip Ensure the foil is sealed tightly around the edges of the baking dish to prevent steam from escaping.

The brisket should be covered in an even layer of the garlic butter mixture. Before sealing with foil, check that the edges of the baking dish are clear of butter to ensure a tight, secure seal that will keep the moisture inside during the long roasting time.

Roasting and Resting

  1. Slow roast and serve
    Roast the brisket in the preheated oven for approximately 4 hours. Check the internal temperature by inserting a probe into the thickest part of the meat. Once it reaches 145°F (63°C), remove from the oven. Let the brisket rest at least 3 minutes, ideally 15 minutes, before slicing against the grain to serve with the accumulated garlic butter juices from the bottom of the dish.
    Look for The brisket should be fork-tender and the juices in the dish should be glossy and fragrant.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Slicing against the grain ensures the meat remains tender and easy to chew.

The brisket is done when it is fork-tender and has reached an internal temperature of 145°F (63°C). The kitchen should smell deeply of roasted garlic and beef. After roasting, ensure the meat rests for at least 15 minutes before carving to allow the juices to settle.

Common mistakes

A common mistake is rushing the cooking process by increasing the oven temperature, which will result in tough, dry meat instead of the desired tender texture.

Another error is failing to seal the baking dish properly; steam is necessary for the breakdown of connective tissue, so ensure the foil is tightly crimped.

Finally, skipping the resting time before slicing can cause the juices to escape immediately, leaving the meat dry. Always let the brisket rest to preserve its natural moisture and achieve the best possible texture.

How to tell it’s done

To determine when the brisket is done, use a meat thermometer inserted into the thickest part of the roast. The brisket is ready when it reaches an internal temperature of at least 145°F (63°C). At this point, the meat should be exceptionally tender, yielding easily to a fork.

Allow the brisket to rest for at least 15 minutes after removing it from the oven. This resting period allows the juices to redistribute throughout the meat, ensuring each slice remains moist and flavorful when served.
