Key Ingredients:
Ground Beef – Provides a hearty, savory base with rich umami flavor, making the casserole filling and satisfying. Lean beef keeps it lighter while still delivering depth.
Ranch Style Beans – Adds creaminess, protein, and a smoky-sweet note that enhances the Tex-Mex profile. They bind the filling together for a cohesive texture.
Ro-tel Tomatoes – A mix of diced tomatoes and green chilies that infuses brightness, acidity, and a subtle heat, balancing the richness of the beef and cheese.
Cheddar Cheese – The melty, golden topping that ties everything together. It provides gooey indulgence and sharpness, making each bite irresistible.
Tortilla Chips – Crushed at the bottom and layered throughout, they absorb the sauce while adding crunch, creating contrast against the creamy filling.
Onion & Taco Seasoning – The flavor builders. Onion brings natural sweetness, while taco seasoning layers in cumin, paprika, and chili powder for bold, authentic taste.
Cream of Chicken Soup – Gives the casserole a creamy body, enriching the texture and adding a subtle, savory undertone that enhances all the other flavors.
Expert Tips:
Enhance the seasoning layers – Don’t just rely on taco seasoning; bloom it in the skillet with the beef and onion to unlock its oils and deeper flavors before adding liquids. This gives the casserole a richer, more complex taste.
Prevent soggy chips – To keep the tortilla chips from becoming overly mushy, layer them just before baking and avoid adding too much liquid to the filling. You want them to soften slightly but still retain texture.
Caramelize your onions – Instead of simply softening the onions, cook them a little longer until they caramelize slightly. This adds a sweet-savory depth that balances the spiciness of the Ro-tel tomatoes.
Use two cheese layers strategically – Place one layer of cheddar in the middle so it melts into the filling, creating gooey pockets, and the other layer on top for that bubbly golden crust.
Adjust spice to your liking – Add fresh jalapeños, chipotle powder, or smoked paprika for extra heat and smokiness. For a milder version, use mild Ro-tel or even substitute with plain diced tomatoes.
Rest before serving – Allow the casserole to sit for at least 10 minutes after baking. This lets the layers firm up, making it easier to cut and serve while preventing it from collapsing into a mushy mix.
Brighten at the end – Add a squeeze of fresh lime juice or sprinkle of cilantro right before serving to cut through the richness and bring a fresh, zesty contrast.
Easy Mexican Casserole
Ingredients
Ground beef – 1 pound lean, browned and drained
Ranch Style beans – 1 can (undrained)
Tortilla chips – 1 bag (10–12 oz), lightly crushed
Ro-tel tomatoes – 1 can (diced tomatoes with green chilies)
Onion – 1 small, finely chopped
Cheddar cheese – 2 cups shredded, divided for layering
Taco seasoning – 1 package
Cream of chicken soup – 1 can
Water – ½ cup
Toppings – Sour cream and salsa, for serving
Instructions
Preheat the oven:
Set your oven to 325°F (165°C).
Lightly grease a 9×13-inch casserole dish and set aside.
Cook the beef:
In a large skillet over medium heat, brown the ground beef until no longer pink.
Drain off any excess fat.
Build the filling:
Stir in the Ranch Style beans, Ro-tel tomatoes, chopped onion, taco seasoning, cream of chicken soup, and water.
Let the mixture simmer over medium-low heat for a few minutes until well combined and heated through.
Assemble the casserole:
Spread a layer of crushed tortilla chips across the bottom of the prepared dish.
Add a layer of the meat and bean mixture, then sprinkle with half of the shredded cheddar cheese.
Repeat the layers with the remaining chips, meat mixture, and cheese.
Bake:
Cover the dish with foil and bake for 20–30 minutes, or until hot and bubbly.
Rest and serve:
Remove from the oven and let the casserole rest for 5–10 minutes before serving.
Top with sour cream and salsa for extra flavor.
Important Notes When Making Easy Mexican Casserole:
Ground beef substitutions – While lean beef works best to keep the dish hearty yet not overly greasy, you can swap with ground turkey or chicken for a lighter option, or use chorizo for a bolder, spiced flavor. If using fattier beef, make sure to drain excess grease to avoid an oily casserole.
Beans matter – Ranch Style beans give this dish its signature Tex-Mex character, but you can use black beans, pinto beans, or refried beans for a slightly different flavor and texture. Always taste the filling before layering, since different beans bring varying salt levels.
Soup as a binder – The cream of chicken soup not only adds richness but also helps bind the filling. You may substitute cream of mushroom or cream of celery soup if you prefer a deeper umami note or need a poultry-free option.
Cheese quality counts – Shred cheddar cheese from a block rather than using pre-shredded, as it melts more smoothly and creates that gooey, indulgent texture. Mixing in Monterey Jack or Pepper Jack can add extra creaminess or spice.
Chip layering tip – Lightly crush tortilla chips to medium-sized pieces—too fine and they turn to mush, too large and they won’t absorb enough flavor. Balance is key for texture.
Bake covered, finish uncovered – Covering with foil keeps moisture in and prevents the top from burning. For the last few minutes, uncover the dish to allow the cheese to bubble and brown beautifully.
Serving and sides – Let the casserole rest 5–10 minutes before slicing to avoid a runny serving. Pair with a simple green salad, guacamole, or Spanish rice to complete the meal.
Storage and reheating – Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the oven at 325°F until warmed through to preserve texture, or microwave individual portions for convenience. This casserole also freezes well for up to 2 months—wrap tightly and thaw in the fridge overnight before reheating.
How To Enjoy Easy Mexican Casserole After Cooking:
Right After Baking
Let it rest first – Allow the casserole to sit for 5–10 minutes once it’s out of the oven. This helps the layers set, making it easier to slice and serve without falling apart.
Serve hot and bubbly – The melted cheese and flavorful filling are best enjoyed while warm, when the chips are still slightly crisp around the edges.
Serving Suggestions
Classic toppings – Add a dollop of sour cream and a spoonful of salsa for a cool and tangy contrast to the rich, cheesy casserole.
Fresh garnishes – Sprinkle with chopped cilantro, sliced green onions, or diced avocado to add brightness and freshness.
Extra heat – For spice lovers, drizzle with hot sauce, add pickled jalapeños, or spoon on some pico de gallo.
Balancing sides – Pair with a crisp green salad, Mexican rice, or black beans to round out the meal.
How to Enjoy in Portions
Family-style – Bring the casserole dish straight to the table and let everyone serve themselves. This makes for a fun, communal dining experience.
Plated individually – For neater presentation, cut into squares or rectangles and serve each portion topped with your choice of garnish.
Leftovers
Reheat properly – Warm leftovers in the oven at 325°F until hot, which helps restore the texture of the chips. For quick reheating, use the microwave, but expect softer chips.
Transform them – Wrap reheated portions in a tortilla for a quick burrito, or spoon over tortilla chips to create nachos.
Freezer Enjoyment
Make-ahead meal – If frozen, thaw overnight in the fridge, then reheat covered in the oven until hot. This makes it a perfect weeknight or meal-prep option.

Frequently Asked Questions:
Can I make this casserole ahead of time?
Yes. You can fully assemble the casserole (without baking), cover it tightly with foil, and refrigerate it for up to 24 hours. When ready to serve, bake it as directed, adding 5–10 extra minutes since it will be chilled.
Can I freeze the casserole for later?
Absolutely. Assemble the casserole, wrap it tightly with foil and plastic wrap, and freeze for up to 2–3 months. To bake, thaw overnight in the fridge and then cook as directed. You can also bake it straight from frozen, but extend the baking time by 20–25 minutes.
What kind of beans work best if I don’t have Ranch Style beans?
If Ranch Style beans aren’t available, you can substitute with pinto beans, black beans, or even kidney beans. Just be sure to taste and adjust the seasoning since Ranch Style beans are slightly sweet and smoky.
How can I make this casserole spicier?
To add extra heat, you can use spicy Ro-tel tomatoes, add diced jalapeños, mix in hot sauce, or sprinkle crushed red pepper into the meat mixture.
What side dishes go well with Mexican Casserole?
This casserole is hearty on its own, but it pairs beautifully with a side salad (like Mexican street corn salad), cilantro-lime rice, or refried beans. A squeeze of lime over the top also enhances the flavors.
How do I keep the tortilla chips from getting too soggy?
To avoid overly soggy chips, lightly crush them instead of making fine crumbs. Also, bake the casserole uncovered for the last 5 minutes to let excess moisture evaporate and crisp up the top layer.
Can I use ground turkey or chicken instead of beef?
Yes. Ground turkey or chicken both work well. Since they’re leaner, you may want to add a splash of olive oil during cooking and increase the taco seasoning slightly for extra flavor.
How do I ensure the casserole doesn’t dry out while baking?
Covering the dish with foil during baking helps lock in moisture. If it still looks dry, you can add a bit more water, broth, or even an extra spoonful of cream of chicken soup before layering.
What’s the best way to melt the cheese evenly?
For smooth, even melting, sprinkle cheese between the layers instead of only on top. Use freshly grated cheddar cheese if possible—it melts better than pre-shredded cheese, which often contains anti-caking agents.
Can I add vegetables to the casserole without changing the texture too much?
Yes. Sautéed bell peppers, zucchini, or corn can be added to the meat mixture. Make sure to cook off excess moisture first so the casserole doesn’t become watery.
