Cut the chuck roast into smaller chunks
Season with salt/pepper/ and garlic powder
Turn instant pot on sauté function and add olive oil to coat the bottom
Place chunks of beef one side first to brown. Then flip to brown the other side Only flipping once or twice just want all sides browned.
Once all sides brown set instant pot aside.
Now using a blender combine all of the ingredients except for the chicken broth. Once the other ingredients are completely combined, add chicken broth and blend again.
Retrieve the instant pot (or crock pot with the beef) add the bay leaves, half of an onion and pour the sauce over the beef.
Ensure that all of the pieces are covered by the sauce.
Turn the instant pot on slow cook function for 4 hours. Or if slow cooking for 6-7 hours.
In the instant pot, once the 4 hours are up, check the texture of the beef. If it is still tough, you can turn the instant pot on “meat/stew” function and allow to natural release. Or manual for approximately 25 min.
You want the beef to be tender and able to be pulled apart (like strings)
Once the roast has reached the desired texture (tender and easily torn apart) take the beef chunks out of the sauce leave the bay leaves and onions.
Shred the beef apart with a fork and knife. (You want this beef shredded- not in small chunks)
Enjoy as a taco, a rice bowl, or over nachos!
