This Mexican casserole brings together all the bold flavors of a classic taco night in one easy, comforting dish that’s perfect for feeding a crowd or meal prepping for the week. It layers seasoned ground beef, ranch style beans, tangy tomatoes, and crunchy tortilla chips under a blanket of melted cheddar cheese, creating a hearty, satisfying meal that always hits the spot.

I first made this recipe when I wanted to use up leftover taco fixings, and my family has asked for it repeatedly ever since. The combination of crispy chips softened by the rich meat mixture is pure comfort.

Ingredients

  • One pound lean ground beef: for a juicy, flavorful base choose fresh meat with good marbling
  • One can Ranch Style beans: which add creaminess and a subtle spiced flavor
  • Tortilla chips: around ten to twelve ounces crushed for that irresistible crunchy layer opt for thicker chips so they don’t get mushy
  • One can Ro-tel tomatoes: to bring a little heat and acidity pick regular or mild depending on your spice preference
  • One small onion: chopped finely to build sweetness and depth
  • Two cups shredded cheddar cheese divided: offers the gooey, melty texture sharp cheddar works best for punchy flavor
  • One package taco seasoning: to infuse the meat with traditional Tex-Mex spices
  • One can cream of chicken soup: to add creaminess and help bind everything together
  • Half a cup water: which helps simmer the mixture to the right consistency
  • Sour cream and salsa: for topping and an added cool, fresh contrast

Step-by-Step Instructions

Sear the Ground Beef:
Cook one pound of lean ground beef over medium-high heat in a large skillet until browned through and no pink remains. Drain off excess fat to keep the dish from becoming greasy but retain flavor.
Combine with Beans and Veggies:
Add one can of Ranch Style beans, one can of Ro-tel tomatoes, one chopped small onion, and taco seasoning to the beef. Stir in one can of cream of chicken soup and half a cup of water carefully. Lower heat to medium-low and simmer gently until everything is well combined and heated through.
Prepare the Casserole Base:
Preheat your oven to 325 degrees Fahrenheit. Grease a 9-by-13-inch casserole dish to prevent sticking and make cleanup easier.
Layer the Ingredients:
Start by spreading a layer of crushed tortilla chips on the bottom of the dish. Spoon half the meat and bean mixture evenly over the chips. Sprinkle with half the shredded cheddar cheese. Repeat the layering with the remaining tortilla chips, meat mixture, and cheddar cheese.
Bake Until Bubbly:
Cover the casserole with foil and bake for twenty to thirty minutes. You want the cheese melted and bubbling but not burnt.
Rest Before Serving:
Remove casserole from the oven and let it sit for five to ten minutes. This resting time allows the layers to settle and makes slicing easier. Serve topped with dollops of sour cream and fresh salsa for bright flavor contrast.

My go-to favorite is the Ranch Style beans—they add a distinct flavor that elevates the whole casserole. One family dinner, my son said it was the best thing he had eaten all week, and that made me feel proud and eager to make it again and again.

Storage Tips

This casserole keeps well covered in the fridge for up to four days. Reheat in the oven or microwave until warmed through, adding a little extra cheese on top if you like. You can also freeze individual portions wrapped tightly; thaw overnight in the fridge before reheating.

Ingredient Substitutions

Ground turkey or chicken works just as well if you want a leaner option. Black beans or pinto beans can replace Ranch Style beans for a different but still delicious twist. Use a can of diced tomatoes with green chiles if you cannot find Ro-tel. Swap cream of mushroom or cream of celery soup if you prefer a different flavor profile or need a vegetarian version using meatless crumbles.

Serving Suggestions

Pair this casserole with a simple green salad or Mexican street corn for extra veggies. Add a wedge of lime on the side to brighten the flavors. Serve with warm flour or corn tortillas for scooping up every last bite.
