History and Fun Facts About Mexican-Inspired Casseroles

Casseroles as we know them became popular in American kitchens during the mid-20th century, when one-dish meals were seen as convenient, thrifty, and family-friendly.

As Mexican and Tex-Mex flavors grew in popularity across the U.S., home cooks began layering tortillas, rice, beans, salsa, and cheese into baked casseroles that blended comfort food with bold seasoning.

This creamy Mexican chicken & rice casserole continues that tradition, taking advantage of rotisserie chicken for speed and combining pantry staples like beans and corn into something that feels hearty, homemade, and vibrant.

The Role of Each Ingredient

• Mexican-style rice lays the flavorful, seasoned foundation of the casserole.

• Rotisserie chicken adds tender, juicy protein without extra cooking.

• Salsa blends into the rice, giving tang, spice, and moisture.

• Sour cream adds creaminess and balances the seasoning.

• Taco seasoning infuses the rice mixture with Tex-Mex flavor.

• Black beans provide hearty texture and plant-based protein.

• Corn adds sweetness and a pop of color.

• Mexican cheese blend melts into a gooey topping that pulls everything together.

Substitution Tips and Advice

You can swap in Spanish rice, instant white rice, or even leftover rice seasoned with taco spices if you don’t have boxed Mexican rice on hand.

 Rotisserie chicken can be replaced with shredded cooked chicken breasts or thighs, or even taco-seasoned ground beef for a different flavor profile. 

For a vegetarian version, skip the chicken and add extra beans, zucchini, or bell peppers.

Cheese is flexible too — cheddar, Monterey Jack, or pepper jack all work beautifully.

Time and Money-Saving Tips

Buy pre-pulled rotisserie chicken from the deli section to skip shredding it yourself. 

Make the rice ahead of time and store it in the fridge to save 15 minutes on prep. 

You can also assemble the casserole in the morning and bake it in the evening, letting the flavors meld together.

Storage and Make-Ahead Instructions

Refrigeration: Store leftovers in an airtight container in the fridge for up to 4 days. Reheat in the microwave or oven until warmed through.

Freezing: Wrap the casserole tightly in foil and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Make Ahead: Prepare the rice mixture and layer the casserole up to a day in advance. Cover tightly and refrigerate, then bake when ready to serve.
