01 - Preheat oven to 375°F.
02 - Heat olive oil in a large skillet over medium heat. Add chopped onion and cook until softened, about 3 minutes. Add minced garlic and cook for an additional minute.
03 - Add beef, ground cumin, chili powder, smoked paprika, salt, and black pepper to the skillet. Sear the beef on all sides for about 5 minutes.
04 - Pour in beef broth, cover, and simmer over low heat until beef is tender and shreddable, approximately 25 minutes. Add extra broth if needed to maintain moisture.
05 - Remove beef from the skillet and shred with two forks. Return shredded beef to the skillet and mix well with the onions and spices.
06 - Warm tortillas to make them pliable for rolling.
07 - Spread 1/2 cup of green enchilada sauce evenly on the bottom of a 9x13-inch baking dish. Fill each tortilla with shredded beef, roll tightly, and arrange seam-side down in the baking dish.
08 - Pour the remaining green enchilada sauce evenly over the filled tortillas. Sprinkle shredded cheese on top.
09 - Bake in preheated oven for 20 minutes until cheese is melted and bubbly.
10 - Sprinkle chopped cilantro and sliced jalapeño over the enchiladas. Serve with sour cream if desired.
