How would you like to make a brisket taste like authentic smoked brisket while using your oven? You can get that savoury, crispy flavour and texture with just oven cooking the brisket, but you have to know how long to cook a brisket in the oven.

The length of time you cook your brisket really affects the flavour and texture. Cooking a brisket for too long will dry it out and make it a little tough. It also means the juices will dry out, so it won’t be as flavourful and tender as it could be.

If you don’t cook it long enough, your brisket may be too soft and might not have the right texture you are looking for.

Knowing how long to cook brisket in oven is essential for the tastiest, tenderest, juiciest brisket.

What Is the Right Temperature to Cook Your Brisket at?

One of the most important parts of how to cook your brisket is knowing the right temperature to cook it at. How long to cook a brisket in oven at 275 degrees Fahrenheit?

If that’s the temperature you want to go with, it will take a while to cook the brisket, and you need to know how long it takes. At this temperature, it can take anywhere from 6 to 8 hours. This is considered a slow cooking method, but that’s great if you want a very tender and juicy brisket.

You can cook your brisket at 350 degrees Fahrenheit, if you would rather. Of course, the cooking duration changes with the temperature. How long to cook brisket in oven at 350 Degrees Fahrenheit? This will take about four hours at this temperature.

However, there’s something you need to know about cooking your brisket and getting the right flavour and texture.

Changing the Temperature

One of the cooking tips experienced chefs always use for how long to cook beef brisket in oven is that you change the temperature partway through. So, if you are cooking at 350 degrees Fahrenheit, this is just the initial temperature.

What you’ll need to do is after the first hour change the temperature down to 300 degrees Fahrenheit. This is when you add beef stock if you’re making a saturated beef brisket. Cook at 300 degrees Fahrenheit for the remaining 3 hours, or until the brisket becomes tender enough that you can stick your fork in it easily.

Other cooking temperatures come with similar requirements for changing the temperature partway through. How long to cook brisket in oven at 325 degrees Fahrenheit? You start at the 325 and cook for an hour and 10 minutes. Then, reduce the temperature to 250 degrees Fahrenheit and cook for another 45 minutes per pound.

You don’t always need to change the temperature, however. You can simply cook the brisket at a set temperature and cook it per pound. How long to cook a brisket in the oven at 250 degrees Fahrenheit?

You can cook it for an hour and 15 minutes per pound. Cook it in foil to ensure the juices stay trapped inside. Then, open the foil and cook for another 45 minutes to ensure the brisket is cooked all the way through.

Now you know how long to cook brisket in oven per pound. You can use this same method for how long to cook a 14-lb. brisket in the oven or whatever size brisket you have.

Serving the Brisket

When serving your brisket, be sure to let it rest after it comes out of the oven. When you slice it, make sure to cut against the grain. What this does is give you a tender cut of meat that isn’t so tough and difficult to chew through.

Rewarming the Brisket

The best way to reheat brisket is to use the oven. You can you preheat the oven to 350 degrees and put your cold brisket into aluminium foil. The brisket warms quickly and will only need to cook in the oven for about 15 minutes.

You may need to cook your brisket for longer if the pieces are very thick or if you’re putting a lot of pieces into the oven at once. If cooking lots of pieces or larger slices, you can cook for up to 20 minutes to rewarm them. The foil wrapped brisket can lay on the oven rack directly or can be placed on a baking sheet.

It’s always best to use all the brisket after the initial cooking process, because reheating the brisket is what causes it to lose the crispy texture on the exterior.

Brisket Cooking Tips

I’ve answered, “How long does it take to cook a brisket in the oven?”, and now I want to share a few tips on cooking the brisket.

It’s best to cook the entire brisket and not slice it up before you cook it. What this does is ensure that you get a crusty top for the meat and a juicy overall brisket. When you cook the brisket as a whole, the juices from the fatty part will seep down into the rest of the brisket, making it tender and moist.

I think it is best to choose a brisket that has some fat on it. This will make for a juicier and tastier brisket overall. You can usually pick from a few different cuts of brisket, and I suggest choosing the fattier one with more marbling.

There are a number of ways you can cook the brisket, and I’ve covered how to cook it in the oven and how long we should cook it for, but traditional brisket is made in a smoker. Not everybody has a smoker on hand, so knowing how to cook it in the oven can be helpful. However, if you want that traditional brisket taste and experience, a smoker is essential.

I would also suggest seasoning your brisket before you bake it in the oven. The rub or seasoning mix that you use is up to you, but make sure you coat at least the top of the brisket before cooking it. This is a meat that benefits from a savoury seasoning, and you can use a pre-made rub or mix it up yourself using spices and seasonings.

For best cooking results, use a few layers of foil on your brisket. This works better than just a single layer of foil because it traps the juices and flavour in and prevents anything from seeping out. It also allows the oils and fats from the brisket to permeate from the top down to the bottom, keeping your brisket moist and flavourful.
