Ground beef is the most common choice because it’s easy to cook quickly and is usually the most affordable option. However, you can certainly make this easy beef enchiladas recipe with a shredded roast or leftover steak! You don’t need much, maybe a cup or two, and be sure to chop up steak pieces nice and small so they mix into the filling better. And since the meat is already cooked, sauté the onion and garlic first, then stir in the beef until warmed.
