What You’ll Need
Here’s what you’ll need to gather for this delicious casserole. Don’t worry, it’s all pretty standard fare, probably already lurking in your pantry!
- Lean Ground Beef (or Ground Chicken/Turkey): The leaner, the better, for less grease and a cleaner taste. About 1.5 pounds should do the trick.
- Onion (1 medium): Finely chopped, for a little bite and savory sweetness.
- Taco Seasoning Mix (2 packets): Your favorite brand, or unleash your inner chef and make your own!
- Black Beans (1 (15-ounce) can): Rinsed and drained. These hold their shape beautifully in the oven.
- Diced Tomatoes with Green Chilies (1 (10-ounce) can): Adds a touch of heat and a vibrant pop of color.
- Sour Cream (1 cup): For that essential creamy tang and richness.
- Fritos Corn Chips (1 large bag): The star of the show! These are non-negotiable for authentic Frito pie vibes.
- Mexican-style Shredded Cheese (2 cups): A generous amount for ultimate cheesiness.
- Your Favorite Toppings: Get creative! Guacamole, salsa, shredded lettuce, jalapenos, and more!
Step-by-Step Instructions
Let’s get cooking! This recipe is surprisingly simple. Follow these steps and get ready for a flavor explosion.
- Preheat & Prep: Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish. Chop your onion finely. If you’re using frozen ground meat, make sure to defrost it completely first.
- Brown the Meat: In a large skillet over medium-high heat, brown your ground beef (or chicken/turkey) until cooked through, breaking it up with a spoon as it cooks. Drain any excess grease. Tip: For even browning, don’t overcrowd the pan. Work in batches if needed.
- Sauté the Onion: Add the chopped onion to the skillet and sauté until softened, about 3-5 minutes. Tip: Don’t burn the onions! Keep a close eye and reduce the heat if necessary.
- Season and Simmer: Stir in the taco seasoning mix and cook for another minute, allowing the spices to bloom. Then, add the drained black beans and diced tomatoes with green chilies. Simmer for 5 minutes, allowing the flavors to meld.
- Assemble the Casserole: Pour about half of the Fritos into the prepared baking dish, creating a crispy base. Spread the meat and bean mixture evenly over the chips. Tip: Press gently to create an even layer.
- Top it Off: Spread the sour cream evenly over the meat mixture. Then, generously sprinkle the remaining Fritos over the sour cream, creating a crunchy top layer. Finally, cover everything with a mountain of Mexican-style shredded cheese.
- Bake to Perfection: Bake for 20-25 minutes, or until the cheese is melted, bubbly, and golden brown, and the casserole is heated through. Tip: Keep an eye on it – ovens vary, so adjust baking time as needed.
- Serve and Enjoy: Let the casserole cool slightly before serving. Garnish with your favorite toppings and dig in!
Tips for Success
Here are a few extra tips to ensure your Walking Taco Casserole turns out perfectly every time:
- Don’t overcook the meat: Overcooked meat can be dry and tough. Aim for a nice brown color and cooked-through texture.
- Use fresh or high-quality canned ingredients: The quality of your ingredients will directly impact the flavor of your casserole.
- Don’t skip the sour cream: It adds a wonderful creamy contrast to the crunchy chips and savory meat.
- Adjust the spice level: Add more or less taco seasoning to suit your preference. For extra heat, add a pinch of cayenne pepper or some chopped jalapeños.
- Let it rest: Allowing the casserole to rest for a few minutes before serving helps the cheese set and makes it easier to serve.
Variations to Try
Want to switch things up? Here are a few fun variations to experiment with:
- Vegetarian Version: Replace the ground beef with crumbled vegetarian crumbles or seasoned black beans for a hearty vegetarian option.
- Spicy Kick: Add a pinch of cayenne pepper or some chopped jalapeños to the meat mixture for extra heat.
- Different Beans: Feel free to experiment with other types of beans, such as pinto beans, kidney beans, or even a mix.
- Different Cheese: Monterey Jack, cheddar, or a Mexican cheese blend would all be delicious additions.
- Gluten-Free Option: Use gluten-free corn chips as a substitute for Fritos.

Storing and Reheating
Leftovers? Don’t worry, this casserole is even better the next day! Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply microwave individual portions until heated through, or bake in a preheated oven at 350°F (175°C) for 10-15 minutes, until heated and bubbly. The texture might change slightly upon reheating, but it will still be delicious.
Freezing is also an option. Allow the casserole to cool completely before wrapping tightly in plastic wrap and then aluminum foil. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating as directed above. For best results, add a sprinkle of extra cheese when reheating from frozen.
Frequently Asked Questions
Q: Can I use a different type of ground meat? A: Absolutely! Ground chicken or turkey work well as substitutes for ground beef. Just be sure to cook them until they are no longer pink.
Q: How long does the casserole last in the fridge? A: Stored properly in an airtight container, the casserole will last for up to 3 days in the refrigerator.
Q: Can I make this casserole ahead of time? A: You can assemble the casserole ahead of time and store it, uncovered, in the refrigerator until ready to bake. Add 5-10 minutes to the baking time.
Q: What if I don’t have Fritos? A: While Fritos are traditional, you can substitute with other corn chips, but the texture and flavor might be slightly different.
Q: Can I make this in a slow cooker? A: Unfortunately, this recipe isn’t suitable for slow cooking, as the chips would become soggy. It’s best baked in the oven for that perfect crunchy texture.
