This is a very good dish. Increase the chili powder to taste. I had only 6 tortillas and could have used more. One change I would make is to substitute sour cream for the ricotta cheese. But, of coarse, ricotta is much lower in fat.
Note, these are not enchiladas as such, but a casserole made with typical enchilada ingredients, and very tasty.
A nice satisfying stew. I really liked this. And except for a tiny ½ teaspoon of potato flour it is pretty much devoid of starch, so it’s a good paleo choice. With extra time, it would work well in a slow-cooker. Actual preparation prior to simmering only takes 15 minutes or so.
