Common Mistakes to Avoid

- Ignoring ingredient quality: Using low-quality canned soup or cheese can affect the dish’s overall flavor. Opt for fresh ingredients when possible.

- Not seasoning properly: Skipping or skimping on fajita seasoning can lead to blandness. Be generous with spices for a flavor-packed casserole.
- Skipping the resting time: Cutting into the casserole immediately after baking can make it fall apart. Allow it to rest for a few minutes before serving to set properly.
- Using the wrong pasta type: Substituting orzo with larger pasta may result in uneven cooking. Stick with orzo for the best consistency in this recipe.
