Brisket and a homemade simple, tomato-based sauce slow cooker together in this tender beef recipe. Make this brisket in your slow cooker or Instant Pot.

If this recipe looks similar it’s because I pretty much took my slow cooker holiday brisket recipe and converted the sauce to be healthier, sans the bouillon granules. Removing this and using garlic salt inadvertently makes this recipe paleo and whole30 compliant.
Brisket, A Tough Cut Of Beef
Brisket is a popular cut of beef for braising or slow cooking for a reason. Beef brisket is a cut of meat from the breast of a cow. It’s a tough cut of meat to cook with but the great thing about the slow cooker or pressure cooker (Instant Pot) is that even the toughest cuts will be cooked to melt-in-your-mouth tender. I purchase my brisket with the fat already trimmed. Please note that depending on the size & shape of brisket, you may have to cut it into pieces to get it to fit into the appliance.

To Sear Or Not To Sear
That is the question. For the Instant Pot, it’s an included instruction. For the slow cooker, searing your meat before adding it to the slow cooker is listed as optional. I chose to pan sear my brisket beforehand. I will always leave this as a recommended but optional step. I have made plenty of briskets and roasts in the slow cooker without searing them beforehand and they came out just fine.

Make This Ahead of Time
Slow cooker or Instant Pot brisket can not only be made the day ahead of time and reheated, some might argue that it’s actually better that way. After it cools, I put the entire slow cooker or Instant Pot base right in the refrigerator. The next day, you will be able to easily remove the fat that has hardened. This is also a good time to slice against the grain if you’re going to do so because the meat is easier to cut cold. To reheat, add the brisket back into the slow cooker or Instant Pot and reheat on the warm setting. If you’re using a Crock-Pot brand of slow cooker, did you know that the base is oven safe? Yup, you can pop the entire base in the oven for temperatures up to 400 degrees.

Serving The Brisket
Brisket is a cut of beef that is traditionally served by slicing against the grain. It can also be shredded too. If I’m eating the brisket the day I cook it, the meat is usually so tender that it falls apart I take it out the slow cooker. When that happens, I just shred it down. When I make the brisket a day ahead & cool it overnight in the frig, I usually slice the brisket against the grain. The meat is cold & firm which makes it’s easy to cut. Same taste regardless of how you serve it.
I use a 6-quart slow cooker or Instant Pot to make this recipe.
