01 - Heat olive oil in a large pot over medium-high heat. Add beef and brown on all sides for approximately 5 minutes. Remove meat and set aside.
02 - In the same pot, sauté diced onion until translucent, about 4 minutes. Add minced garlic, cumin, smoked paprika, dried oregano, salt, and black pepper. Cook for 1 minute until fragrant.
03 - Return beef to the pot and pour in beef broth. Cover and simmer on low heat for 1 hour or until beef is tender and easily shredded. Shred meat using two forks and return to the pot with juices.
04 - Preheat broiler. Arrange tomatillos, poblano peppers, and jalapeño on a baking sheet. Broil for 6–8 minutes, turning once, until skins are charred and vegetables are softened.
05 - Transfer charred vegetables to a blender. Add cilantro, garlic, chicken broth, salt, and lime juice. Blend until completely smooth.
06 - Preheat oven to 375°F.
07 - Warm tortillas slightly to prevent cracking. Spread ½ cup of green sauce evenly over the bottom of a 9×13-inch baking dish.
08 - Fill each tortilla with 2–3 tbsp of shredded beef and a sprinkle of cheese. Roll up tightly and place seam-side down in the prepared dish.
09 - Pour remaining green sauce evenly over the assembled enchiladas. Top with remaining shredded cheese.
10 - Bake for 20–25 minutes until cheese is fully melted and sauce is bubbling around edges.
11 - Top enchiladas with sour cream, fresh cilantro, and diced red onion before serving.
