<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 190°C (375°F) and lightly grease a 23 x 33cm (9 x 13-inch) baking dish. Position a rack in the middle of the oven to ensure even heat distribution throughout the casserole.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Heat the olive oil in a large skillet over medium-high heat. Add the diced onion and cook for 3-4 minutes until translucent. Add the minced garlic and cook for another 30 seconds until fragrant, being careful not to let it burn (burnt garlic can add bitterness to your dish).</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Add the ground beef to the skillet, breaking it up with a wooden spoon. Cook until no longer pink, about 5-7 minutes. The fine texture of ground beef allows it to absorb flavors beautifully, so ensure it's broken into small, even pieces for the best flavor distribution.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Add the diced red bell pepper and cook for 2 minutes until slightly softened. Stir in the taco seasoning, salt, and pepper. The seasoning will bloom in the hot fat, releasing more intense flavor than if added to a liquid base.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Pour in the diced tomatoes with their juice and tomato sauce. Add the black beans and corn kernels, stirring to combine everything thoroughly. Simmer for 5 minutes until slightly thickened. The moist filling will soften the tortillas during baking, creating delicious textural contrast with the crispy edges.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Begin assembling your casserole by placing 4 tortillas in the bottom of your prepared baking dish, tearing them if needed to create an even layer with slight overlaps. The overlapping ensures there are no gaps for the filling to fall through while serving.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Spread one-third of the beef mixture over the tortillas, then sprinkle with one-third of the combined cheeses. The cheese between layers acts as a binding agent that helps hold servings together when cut.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Repeat the layering process twice more: tortillas, beef mixture, cheese. Finish with the remaining cheese on top. Be sure to spread the filling evenly, pushing it slightly toward the edges for the most attractive presentation when served.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Cover the baking dish with aluminum foil and bake for 20 minutes. The foil traps steam, helping to soften the tortillas and meld the flavors together. Then remove the foil and bake for an additional 10-15 minutes until the cheese is bubbly and golden brown at the edges.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Remove from the oven and let stand for 5-10 minutes before serving. This resting period is crucial as it allows the layers to set, making it easier to cut clean portions while allowing the flavors to further develop.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Serve warm, garnished with your choice of toppings such as sour cream, diced avocado, fresh cilantro, and lime wedges. The cool, creamy toppings provide a delightful contrast to the warm, spicy casserole. Enjoy your homemade Taco Tortilla Casserole!</li></ol>
