🔪 Equipment Needed
- Large skillet or sauté pan
- Mixing bowl
- Measuring tools
- Spoon or spatula
- 9×13-inch baking dish
- Aluminum foil
- Oven mitts
👩🍳 Step-by-Step Instructions
Step 1: Preheat Your Oven
Preheat oven to 325°F (163°C) . Lightly grease a 9×13-inch baking dish with non-stick spray or oil.
Step 2: Cook the Beef Mixture
In a large skillet over medium heat:
- Brown ground beef until fully cooked — about 6–8 minutes .
- Add chopped onion and stir until softened — about 2–3 minutes .
- Stir in:
- Ro-Tel tomatoes
- Ranch Style beans
- Taco seasoning
- Cream of chicken soup
- Water or broth
- Simmer everything together for 5–7 minutes , stirring occasionally to blend the flavors.
Step 3: Layer the Tortilla Chips
Place half the crushed tortilla chips in the bottom of the prepared baking dish — just enough to create a crunchy base.
Pour half of the beef and bean mixture over the chips.
Repeat layers:
- Crushed chips → beef mixture → crushed chips → beef mixture
Finish with a final top layer of crushed chips — this gives that signature nacho crunch!
Step 4: Top Generously With Cheese
Sprinkle 2 cups shredded cheddar cheese evenly over the top — don’t be shy!
The cheese will melt beautifully into the hot layers below and give you that golden crust we all love.
Step 5: Bake Until Golden & Bubbly
Cover with aluminum foil and bake at 325°F (163°C) for 25 minutes .
Remove foil and bake an additional 10–15 minutes , until the cheese is bubbly and lightly golden.
Let rest for 5–10 minutes before serving — this helps everything firm up.
Step 6: Cool Slightly and Serve Warm
Once out of the oven, let cool slightly before slicing into squares or scooping.
Serve warm with a dollop of sour cream and a spoonful of salsa on the side.
Each bite is packed with meaty warmth , cheesy stretch , and spiced chip crunch — pure Mexican comfort in every mouthful!
