Homemade cheese and onion enchiladas are deliciously cheesy with rich flavor from the traditional corn tortillas and made-from-scratch red enchilada sauce.
Fill each tortilla with an even amount of the cheese mixture, spooning it down the center line of the tortilla. Fold the two unfilled sides to the center, overlapping them, and place the enchilada folded side down in the baking pan.
Pour the remaining sauce over enchiladas in the pan and bake for 30 minutes at 350°F. Top with cheese and reserved green onions and bake until cheese is melted over the top (about 10 more minutes).
