Ingredient Notes
What are Ranch Style beans? Ranch Style beans are pinto beans cooked in a rich, Tex-Mex seasoned sauce with chili spices and onions. They add incredible flavor and texture to this casserole. If you can’t find them, substitute 1 can of pinto beans (drained) plus ½ teaspoon of chili powder and ¼ teaspoon of cumin.
What kind of tortilla chips? Any sturdy tortilla chips work. Restaurant-style or thick-cut chips hold up better to the layers than thin, crispy chips. You can use plain or lightly salted chips.
What is Rotel? Rotel is a brand of canned diced tomatoes with green chilies. It adds a mild heat and tangy flavor. If you can’t find it, substitute 1 can of diced tomatoes (undrained) plus ¼ cup of chopped green chilies.
What kind of cream of chicken soup? Use unsalted cream of chicken soup to control the salt level. Regular cream of chicken soup works too, but reduce or omit additional salt.
What kind of cheese? Sharp cheddar provides the most flavor. Colby Jack or a Mexican cheese blend also work beautifully. Freshly shredded cheese melts better than pre-shredded.
What kind of taco seasoning? Any standard 1-ounce packet works. Use mild, original, or spicy depending on your preference.
Do I need to drain the Rotel? No. Undrained Rotel adds liquid and flavor to the meat mixture.
Step-by-Step Instructions
Step 1: Preheat and Brown the Meat
Preheat your oven to 325°F (163°C) .
In a large skillet over medium heat, brown 1 pound of lean ground beef. Drain off excess fat.
Step 2: Make the Meat Mixture
Stir into the browned beef:
-
1 can Ranch Style beans (undrained)
-
1 can Rotel diced tomatoes & green chilies (undrained)
-
1 small onion, chopped
-
1 package taco seasoning
-
1 can unsalted cream of chicken soup
-
½ cup water
Simmer over medium-low heat until everything is well combined and heated through, about 5–7 minutes.
Step 3: Prepare the Casserole Dish
Grease a 9×13-inch baking dish.
Step 4: Layer the Casserole
First layer: Spread a layer of crushed tortilla chips evenly over the bottom of the dish.
Second layer: Spoon half of the meat/bean mixture over the chips.
Third layer: Sprinkle half of the shredded cheddar cheese (about 1 cup) over the meat.
Repeat layers: Add another layer of crushed chips, the remaining meat mixture, and the remaining cheese.
Step 5: Bake
Cover the casserole dish with foil. Bake for 20 to 30 minutes, until bubbly and hot throughout.
Step 6: Serve
Remove the foil and let the casserole rest for 5 minutes before serving. Serve with sour cream and salsa on the side.

Add Vegetables
Add to the meat mixture:
-
1 cup frozen corn – Adds sweetness
-
1 (4-ounce) can diced green chilies – Extra mild heat

1 (15-ounce) can black beans, drained and rinsed – For extra protein and fiber

Use Rotel with habanero (if you can find it)

Frequently Asked Questions (FAQs)
Can I use a different bean?
Yes. Black beans, pinto beans, or kidney beans all work. If not using Ranch Style beans, add ½ teaspoon of chili powder and ¼ teaspoon of cumin to the meat mixture.
Can I use a different soup?
Yes. Cream of mushroom soup or cream of celery soup both work. The flavor will be slightly different but still delicious.
Can I make this vegetarian?
Yes. Omit the ground beef. Add an extra can of beans (black beans or pinto beans) and 1 cup of frozen corn. Use vegetarian taco seasoning and cream of mushroom soup (or substitute with a plant-based version).
