This Mexican casserole layered with tortillas has the heft of Italian lasagna and is just as tasty.
The lasagna can be assembled up to 1 day in advance. Cover with foil and refrigerate. With dish still covered, increase initial baking time by 5 to 10 minutes.
To make this recipe as Sarah does in her video, decrease the oven temperature to 375 and bake for 35 to 40 minutes.
