Slow Cooker Carne Asada

Directions

1. In a large skillet, heat oil over medium high. Brown beef on all sides, set aside.
2. Add onion, garlic, thyme, oregano and bay leaves; season with salt and pepper. Cook until onion has softened, about 5 minutes. Stir in tomato paste.
3. Transfer beef to the slow cooker (cut the pieces to fit if necessary) with the onion mixture, tomatoes and their juices, chipotle and broth.
4. Cook on high for 12 hours.
5. Using tongs, transfer meat to a large bowl; shred with two forks, discarding any large pieces of fat or gristle. Return meat to pot, and simmer on high until sauce is thick, 30 to 45 minutes more. Season, if necessary, with salt and pepper. Use for tacos, or cover and refrigerate, up to 3 days.
