Preheat your oven to 375°F (190°C).

In a large skillet over medium heat, add the ground beef along with diced onions. Cook for about 5-7 minutes until the beef is browned.

Stir in minced garlic, cumin, and chili powder. Cook for an additional minute.

Lay a tortilla flat and spoon a portion of the beef filling onto the center. Roll tightly and place seam-side down in a greased baking dish.

Pour the enchilada sauce evenly over the top, covering each enchilada generously.

Sprinkle shredded cheese over the enchiladas, then bake uncovered for 20-25 minutes until bubbling and golden.

Let cool for a few minutes before serving. Garnish with fresh cilantro or sliced jalapeños if desired.
