Season the brisket on both sides with thyme, rosemary, garlic powder, salt, and pepper.

Turn the stove onto medium heat and pour olive oil into cast iron pan.

Once the olive oil is hot place the brisket on the cast iron pan, let brown and flip brisket, and brown the other side. DO NOT COOK!

One brisket is brown on both sides remove from cast iron pan and add garlic and onions, cook until translucent.

Once the onions and garlic are done add the brisket back to the pan and cover tightly with tinfoil.

Place cast-iron skillet in the oven for 300F for 2 to 3 hours.

When the brisket is done cooking remove from oven and remove the tin foil. Let the brisket rest for about 30 minutes.

Thinly slice the brisket against the grain and place back in the braising liquid in the cast iron skillet for about 5 minutes. Enjoy!
