Chef’s Tips
Use freshly shredded cheese for the best melt.
Add the lettuce and other fresh toppings only after baking.
If you like extra crunch, reserve some corn chips to sprinkle on top just before serving.
Homemade taco seasoning lets you control the spice level.
For a richer flavor, use a blend of cheddar and Monterey Jack cheese.
Common Mistakes to Avoid
Adding the fresh toppings before baking.
Using too much liquid in the beef mixture.
Overbaking the casserole.
Using stale corn chips.
Skipping the resting time before serving.

Replace the ground beef with ground chicken or ground turkey.
Use pinto beans instead of black beans.
Add diced bell peppers for extra vegetables.
