Pat the pork shoulder dry and cut it into 3–4 large pieces. Season all sides evenly with salt, black pepper, cumin, oregano, chili powder, and red pepper flakes.
4 pounds boneless pork shoulder, 1 tablespoon ground cumin, 2 teaspoons dried oregano, 1 tablespoon chili powder, ¼ teaspoon red pepper flakes, 2 teaspoons salt, 1 teaspoon black pepper
Heat olive oil in a skillet over medium-high heat. Sear the pork on all sides until nicely browned, about 2 minutes per side. Transfer the pork to the slow cooker.
1 tablespoon olive oil
Add the diced onion and minced garlic to the slow cooker. Pour in the orange juice, lime juice, and chicken broth.
1 large onion, 4 cloves garlic, 1 orange, 1 lime, 1 cup chicken broth
Cover and cook on low for 4–5 hours, or until the pork is very tender and shreds easily.
Shred the pork using two forks. For crispy carnitas (optional), spread the shredded pork on a baking sheet and broil for 5–7 minutes, turning once, until the edges are golden and crisp.
Spoon some of the cooking juices over the pork for extra flavor.
Serve warm in corn tortillas or bowls, topped with red onion, avocado, and fresh cilantro.
