Directions
<ol class="no-list-style"> <li class="MethodStepper"> <h4 class="step-title">Step 1</h4> Preheat your oven to 190°C (375°F). Lightly grease your baking dish with cooking spray or a thin layer of oil to prevent sticking. </li> <li class="MethodStepper"> <h4 class="step-title">Step 2</h4> Heat a large skillet over medium-high heat. Add the ground beef and cook until it begins to brown, about 5 minutes, breaking it into small crumbles with a wooden spoon. The fine texture will ensure even distribution of flavor throughout the casserole. </li> <li class="MethodStepper"> <h4 class="step-title">Step 3</h4> Add the diced onion and minced garlic to the beef and continue cooking until the onion is translucent and the beef is completely browned, about 3-4 minutes more. Drain excess fat if needed – leaving a little will help keep the casserole moist. </li> <li class="MethodStepper"> <h4 class="step-title">Step 4</h4> Sprinkle the taco seasoning over the meat mixture and stir to coat evenly. Add the diced tomatoes with their juice and simmer for 2-3 minutes, allowing the flavors to meld and the sauce to thicken slightly. The acidity in the tomatoes will tenderize the meat and add depth to the flavor. </li> <li class="MethodStepper"> <h4 class="step-title">Step 5</h4> Stir in the drained black beans and corn kernels, heating through for about 2 minutes. The combination of protein-rich beans and sweet corn creates a balanced filling with varied textures. </li> <li class="MethodStepper"> <h4 class="step-title">Step 6</h4> Spread half of the lightly crushed tortilla chips in an even layer on the bottom of your prepared baking dish. The chips will soften slightly during baking but maintain some crunch, mimicking the texture of a walking taco. </li> <li class="MethodStepper"> <h4 class="step-title">Step 7</h4> Spoon half of the meat mixture over the chips, then sprinkle with one-third of the grated cheese. Repeat with another layer of chips, the remaining meat mixture, and another third of cheese. </li> <li class="MethodStepper"> <h4 class="step-title">Step 8</h4> Cover the baking dish with aluminum foil and bake for 15 minutes. The foil prevents the top from browning too quickly while allowing the flavors to meld together. </li> <li class="MethodStepper"> <h4 class="step-title">Step 9</h4> Remove the foil, sprinkle the remaining cheese over the top, and return to the oven uncovered for about 10 minutes, until the cheese is completely melted and beginning to bubble and brown at the edges. This creates that irresistible golden cheese crust. </li> <li class="MethodStepper"> <h4 class="step-title">Step 10</h4> Let the casserole rest for 5 minutes before serving – this brief resting period allows the layers to set slightly, making it easier to serve intact portions. </li> <li class="MethodStepper"> <h4 class="step-title">Step 11</h4> Serve warm, allowing everyone to top their portion with shredded lettuce, diced tomatoes, avocado, green onions, and a dollop of sour cream. For extra crunch, offer additional tortilla chips on the side. The contrast of the warm casserole and cool, fresh toppings creates the complete walking taco experience! </li> </ol>
