In addition to the time, the processing steps also significantly affect the dish’s taste. Don’t skip the instructions below to cook brisket with great texture and flavor in the oven. 


The number of ingredients you need will depend on the servings you need. Here are the main ingredients to get the standard beef brisket. 

  • Beef breast. 
  • Olive oil. 
  • Sauce or mustard to taste. 
  • Chili (sweet chili, paprika). 
  • Onion powder. 
  • Garlic powder.
  • Black pepper.
  • Spice.


Once you have all the ingredients ready, it’s time to cook delicious grilled brisket in the oven. Here is the standard processing procedure that you can refer to: 

  • Step 2: Material handling. Cut off the excess fat from the cleaned breast. Depending on your taste, you can altogether remove or keep the fat in the breast. Usually, you should only leave about ¼ of the fat in the breast. 
  • Step 3: Add seasoning. Put the ingredients in a pan and then spread a layer of olive oil over the barbecue. In this step, you also need to add onion powder, salt, pepper, and garlic powder to the meat. 

After seasoning, you should wait a few hours, even a day, to ensure the brisket absorbs the spices. In the meantime, you should store food in the refrigerator to prevent spoilage. 

  • Step 4: Prepare onions and peppers. You need to cut these ingredients into small pieces. You can also prepare more meat broth if you want the dish to be more flavorful. 
  • Step 5: Preheat the oven to 275 degrees F. Once the heating is complete, you can put the food in the oven. To prevent sticking, you can place a layer of aluminum foil on the tray before placing the meat. 
  • Step 6: After about 6 hours of cooking in the oven at 275 degrees F, you can remove the meat tray from the oven and check. Depending on the condition of the meat, you can place the tray back in the oven and continue cooking for about 1 to 2 hours. 
  • Step 7: After a long time in the oven at 275 degrees F, it’s time to take the meat tray out of the range. You should wait about 20 minutes for the dish to cool down before chopping the meat and enjoying it. 


Following the instructions above will ensure that you get evenly cooked dishes. However, to have perfect dishes, following the recipe is not enough. For great flavor and texture, you’ll need to know a bunch of tips below: 

  • Don’t get rid of all the fat in the brisket. Because the breast only consists of meat fibers, it will not be moist enough lacking in flavor. 
  • Maintain a constant temperature throughout the cooking process. Speeding the cooking process by suddenly increasing the temperature can cause the meat to lose its tenderness or even burn. 
  • Prepare the meat thoroughly before you season it. In particular, you should apply two tablespoons of olive oil to the meat after processing. 
  • Use aluminum foil to cover the oven lid. Aluminum foil has good water retention, which helps maintain excellent moisture for the meat while limiting the evaporation of the sauce. If you don’t want the meat to be too hard, in addition to using aluminum foil, you can add a little beef broth to the brisket.

Why cook Beef Brisket “low and slow” in the oven?

Why cook Beef Brisket "low and slow" in the oven

Low and slow is a beef processing technique that you should use. This cooking technique is simple: you just need to keep the oven temperature below 325 degrees F. 

Cooking tough meat for a long time will destroy the connective tissue in the meat, which in turn makes the meat tender. 

Besides, slow cooking will not affect the fat veins in the meat too much. As a result, when cooking meat from 250 degrees F to 325 degrees F, you will still retain the necessary amount of fat, ensuring the meat is always tender and attractive. 

Is beef brisket cooked in liquid or above the liquid?

The beef breast will not be liquefied when processing according to the above recipe. Instead, the slices of meat retain their shape but are still tender enough. 

If you want the brisket to be crumbly, you’ll have to accept the dry scrub that can soak into the sauce. However, the taste of the dish when prepared by new methods is also worth a try. 

Substitutions and variations for beef brisket

You can ultimately create your recipes depending on your taste or available ingredients. 

For example, if you don’t have enough ingredients like chili or onion powder, don’t worry. You can have delicious meat dishes with just salt and pepper. Or you can also go for some bolder creations. For example, you can replace the beef broth with chicken broth, even plain brine.
