<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 your 23 x 33cm baking dish. This ensures your casserole won't stick and makes cleanup easier.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>In a large skillet over medium-high heat, brown the ground beef for about 5-7 minutes, breaking it up with a wooden spoon as it cooks. Drain excess fat if necessary – leaving a little fat will help carry flavor, but too much will make your casserole greasy.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Add the diced onion to the skillet and cook until softened, about 3-4 minutes. Then add the minced garlic and cook for another 30 seconds until fragrant. Be careful not to burn the garlic as it can become bitter.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Stir in the taco seasoning, making sure all the meat is evenly coated. The spices need to bloom in the hot pan to release their full flavors, so let them cook for about 1 minute while stirring.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Add the diced tomatoes with their juice and the tomato sauce to the skillet. Stir to combine and let the mixture simmer for 5 minutes until slightly thickened. The acidity in the tomatoes will help tenderize the meat while adding depth of flavor.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>While the meat sauce is simmering, open your tin of refrigerated biscuit dough and cut each biscuit into quarters. The pieces should be bite-sized to ensure they cook through properly.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Transfer the meat mixture to your prepared baking dish, spreading it in an even layer. Then gently fold the quartered biscuit pieces into the meat mixture, pushing them down slightly but allowing some to remain partially visible. This creates the signature "bubble-up" effect as they bake.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Combine both types of grated cheese and sprinkle evenly over the top of the casserole. The combination of cheeses creates the perfect melt and flavor – the cheddar provides sharpness while Monterey Jack offers exceptional melting properties.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Bake uncovered in your preheated oven for 25-30 minutes, until the biscuits have puffed up and turned golden brown, and the cheese is completely melted and bubbly. The internal temperature should reach at least 74°C (165°F) for food safety.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Remove from the oven and let the casserole stand for 5 minutes before serving. This resting period allows the molten cheese to set slightly and makes serving cleaner and easier.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Top with your choice of fresh garnishes – diced tomatoes, green onions, cilantro, avocado, sour cream, or black olives. The contrast of the hot casserole with cool, fresh toppings creates a delightful eating experience with multiple textures and flavors.</li></ol>
