Step 1

Preheat your oven to 325F and season your roast generously on both sides with salt, pepper and the taco seasoning. Place the chuck roast into a Dutch Oven along with the orange juice, beef stock and onions. Secure the lid on the dutch oven and transfer into the oven to bake for 3.5 - 4 hours.

Step 2

After 3.5 - 4 hours, remove the roast from the oven and it should easily shred it into large chunks using two forks. If it's not quite falling apart, place it back into the oven for an additional 30 minutes with the lid on.

Step 3

Increase the oven heat to 425F. Toss the shredded pieces of meat with the onions and a sprinkle of more taco seasoning onto a baking sheet and place it back in the oven, uncovered, for 15-25 minutes until it starts to caramelize and get crispy on some parts.

Step 4

Make the guacamole while the roast is getting caramelized.

Step 5

Char your tortillas over an open flame and assemble your tacos by adding a dollop of guacamole, a large spoonful of the shredded meat, and your favorite taco toppings or salsa.
