FAQs

Can I make this ahead of time?

Yes, you can prep the layers and refrigerate overnight. Just start the slow cooker in the morning. It is a very family-friendly way to meal prep.

Will the tortillas get soggy?

The tortillas soften and absorb the delicious juices. They create a texture similar to soft noodles or tamales. Most people find this very satisfying.

How do I know it is done?

The casserole is done when the edges are bubbly. The cheese should be completely melted and golden. The flavors will be perfectly melded together.

I hope this meal brings a little extra joy to your table. You deserve a dinner that is both easy and amazing. Happy cooking!
