Common Mistakes to Avoid

Using too much liquid.
Extra broth can make the casserole mushy.

Skipping seasoning.
Tex-Mex dishes rely on spices, so don’t go shy here.

Not covering during the first bake.
Covering helps the rice cook evenly.

Adding cheese too early.
Otherwise it can burn before the casserole finishes cooking.

Alternatives & Substitutions

Swap the protein.
Ground turkey or lean beef works well instead of chicken.

Use brown rice.
Just increase cooking time slightly.

Add extra vegetables.
Bell peppers, zucchini, or jalapeños add great flavor.

Want extra creaminess?
Mix in a little Greek yogurt before baking. IMO it makes the texture amazing without adding much fat.
