Preheat your oven to 375°F (190°C) so it's hot and ready when you're done preparing your enchiladas.
In a skillet over medium heat, brown the ground beef along with diced onions until they are translucent, which should take about 5-7 minutes.
Add minced garlic, cumin, and chili powder to the skillet; sauté everything together for another minute until fragrant.
Spoon generous portions of the beef mixture onto each tortilla, roll them tightly, and place seam-side down in a greased baking dish.
Pour the enchilada sauce over the rolled tortillas and then sprinkle shredded cheese on top for that delicious melt.
Bake uncovered in your preheated oven for 20-25 minutes until bubbly and golden brown on top.
