Season the beef cubes with salt and pepper. In a skillet over medium-high heat, brown the beef on all sides, about 2 minutes per side. If you're using a multi-cooker, use the "Brown" or "Saute" function to brown the beef in batches.
Transfer the seared meat to your slow cooker pot. Sprinkle onions, garlic, bay leaves, chili powder, cumin, and oregano over top. Add the broth and chipotles in adobo. Stir to combine.
Cover and set to slow cook on “High” for 4 hours or “Low” for 8 hours, until the beef is tender and shreds easily.
Remove the beef and chiles from the pot, leaving the liquid. Discard the bay leaves. Using two forks, shred the beef and chiles then return them back to the sauce. Serve topped with diced onions, cilantro, and lime.
