  • 6 tortillas
  • 1/2 lb. Cheddar cheese
  • 1 (15 oz.) can Ranch Style or chili beans
  • 1 (10 oz.) can Ro-Tel tomatoes and chiles
  • 1 large chopped onion
  • 1 can cream of chicken soup

Instructions

  3. Spread the cream of chicken soup over the top layer.

Tips & Substitutions

For added flavor, consider sautéing the chopped onion with the ground beef. If you're looking for a healthier option, use ground turkey instead of beef or opt for whole wheat tortillas. You can also substitute black beans for the chili beans if desired. To enhance the spice level, add jalapeños or use a spicier variety of Ro-Tel tomatoes.

Serving Suggestions

Serve this delightful casserole with a side of Pat'S Favorite Spanish Rice for a complete meal. Fresh toppings like sour cream, avocado, or cilantro can enhance the dish. You might also enjoy pairing it with a crisp green salad or tortilla chips for a delightful crunch. This recipe is a fantastic choice for family gatherings or potlucks.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, place individual portions in the microwave for about 1-2 minutes or cover the casserole with foil and warm it in a 350°F oven for 20-25 minutes until heated through. Adding a little water can help keep it moist while reheating.

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes, you can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours before baking. Just be sure to cover it tightly with plastic wrap or foil to prevent it from drying out. When ready to bake, remove it from the fridge and allow it to sit at room temperature for about 30 minutes before placing it in the oven.

What can I use instead of cream of chicken soup?

If you want to avoid cream of chicken soup, you can use a homemade white sauce or a can of cream of mushroom soup as an alternative. Both options will still provide a creamy texture and rich flavor. For a lighter version, try substituting with a can of low-fat cream soup.

Can I freeze the Mexican casserole?

Yes, this casserole freezes well. To freeze, let it cool completely after baking, then wrap it tightly in plastic wrap and aluminum foil. It can be stored in the freezer for up to 3 months. When ready to eat, thaw it in the refrigerator overnight and reheat it in the oven or microwave.
