What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Shred the chicken while it's still warm – it pulls apart much more easily than cold chicken.
- 2Overlap the tortilla quarters slightly in each layer so there are no gaps, which helps bind the casserole together.
- 3Don't rush the onion-and-pepper sauté; well-softened vegetables build the sweet-savory foundation of the sauce.
- 4Let the baked casserole rest for 10 minutes before slicing – this allows the layers to set so it holds its shape.
- 5For a deeper smoky flavor, use fire-roasted diced tomatoes in place of fresh ones.
- 6If you prefer a thicker sauce, reduce the water to 1/4 cup and simmer the tomato mixture an extra 2-3 minutes.
