I think Enchiladas made with Flour Tortillas are good. I also like Corn Tortillas but when I make Enchiladas at home I use Flour ones.
For chicken Enchiladas I do not make them with Sour Cream because nobody in my family likes Sour Cream. I also do not use canned Enchilada sauce because nobody likes that either.
I make a Chili Cheese sauce the kids would drink with a straw if I would let them.
For the chicken part, you cook/brown up some chicken breasts or some Chicken Strips and shred them, put them back in the pan with a 1/4 cup water and a few Tablespoons of Taco seasoning and cook that off.
I use shredded COLBY cheese. A lot of it. =) (we love Cheesy Enchiladas)
For the sauce I use Wolf brand Chili with no beans and Velveeta Cheese. I thin the Chili down with about a 1/4 cup water to 2 cans Chili and blend it smooth in the blender or food processor. We don't like the lumpiness of the chili.
Once it is blended smooth put it in a pan with about 1/3 of a large block of Velveeta cheese cubes and cook it until the Cheese is melted and the sauce looks kind of dark Orange.
I also make that Chili Cheese in place of Velveeta Rotel dip only I add the whole block of cheese and just one can of smooth Chili.
Anyway, I always micro the Tortillas for about 45 seconds before I start rolling them.
Place a few tablespoons of the shredded Chicken in the Tortilla, place a big handful of cheese along the chicken mixture and roll the Enchilada up. Line them along the inside of a 13X9 glass baking pan that has had some of chili cheese sauce poured into the bottom. After you finish rolling them all up dump the remaining chili cheese sauce on top and some more shredded cheese on top of the whole pan of enchiladas. (You can usually fit 8 big Enchiladas into a 13X9 pan) One Enchilada is very large and if you make rice or beans to go with it, one Enchilada should be a serving size for most grown ups, half for a small kid.
Bake that at 350 degrees for about 30 minutes.
Sometimes I like more sauce and use 3 cans of chili (big cans) but usually 2 is enough. If you buy the small serving size cans you will need 4 cans or maybe 5.
