If I split into 8×8 pans, what would you recommend for bake time?
We use a no-boil, overnight recipe for lasagna that works very well and we like the concept so will have to give this tasty sounding Mexican dish a try.
Can this be cooked right away without refrigerating overnight?
I haven’t tried that, so I can not say. Letting the pasta sit overnight in the liquid softens it.
If you try it, let us know how it turns out.
I was leary about using pasta, but it was amazing! Everyone loved it! Such an easy recipe.
This recipe sounds wonderful! I probably would add a can of Ro-Tel to give it a kick. Do you think it needs to be drained? Thanks!
I added drained Rotel and it was amazing!
SO glad you enjoyed it! Love the addition of Rotel
