A beef brisket is a cut of meat from the breast section of the cow, which is rich in a connective tissue collage causing the meat to be tough in nature. Whenever a beef brisket is used in most recipes, it usually needs a long slow cooking in order to have a tender cut of meat when its ready. Additionally, we want to ensure we use an appropriate temperature, not so high and not too low, in order to achieve the tenderness of the meat.

In this recipe, I used a 260°F (about 126°C) temperature and after three hours of cooking, it surely gave a really delicious cut of beef brisket.

Kitchen Utensils Needed

In this recipe, we will use the basic utensils you have in your kitchen such as the following:

  • 9x9 baking pan
  • knife
  • cutting board
  • spoon (for drizzling sauce)
  • small bowls for preparing dry and liquid ingredients
  • oven
  • aluminum foil
  • serving plate


  • 1 1/2 lbs. or 0.70 kg of beef brisket
  • 1/2 cup soy sauce
  • 1 tablespoon of sugar
  • 1/4 cup vinegar
  • 2 Thai peppers (optional)
  • 1 cup of water
  • 1 teaspoon of pepper
  • 2 1/4 teaspoons of salt
  • 4 cloves of garlic
  • 1 medium sized onion


  1. Preheat oven to 260°F or about 126°C. You want the temperature slightly above 250°F, but don't push it too high because it will make your brisket tough in the end, instead of being tender.

  2. Measure and prepare dry ingredients in small bowls - salt, pepper, and sugar. It may seem like an extra step, but it makes the prep more organized.

    Important Tips

    • Ensure the oven is pre-heated fully.
    • Do not open the aluminum foils to check during cooking.
    • Use a glass pan, so you can check the fluid level during the cooking process.
    • Use the right size pan so that the marinade slightly covers the meat. We used a 9x9 Pyrex glass cooking pan.
