Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 180°C (350°F) and lightly grease your baking dish with a bit of olive oil or cooking spray.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Cook the pasta in a large pot of salted boiling water until just al dente, about 2 minutes less than package instructions. The pasta will continue cooking in the oven, so slightly undercooking it now prevents mushiness later. Drain and set aside.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Heat the olive oil in a large skillet over medium-high heat. Add the ground beef and cook until browned, about 5-7 minutes, breaking it up with a wooden spoon as it cooks. The caramelization of the meat creates rich flavor compounds that will enhance the overall taste of your casserole.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Add the diced onion and bell pepper to the skillet with the beef and cook until softened, about 3-4 minutes. Then add the garlic and cook for another minute until fragrant. Be careful not to burn the garlic as it can become bitter.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Stir in the tomato paste and cook for 1-2 minutes to deepen its flavor (this helps develop umami notes). Then add the chopped tomatoes, beef stock, Worcestershire sauce, Dijon mustard, dried oregano, and paprika. Season with salt and pepper to taste.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Bring the mixture to a simmer and cook for about 5 minutes until slightly thickened. The reduction concentrates flavors and ensures your casserole won't be watery when baked.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Remove from heat and fold in the cooked pasta, ensuring it's well coated with the sauce. The pasta will absorb some of the sauce as it bakes, developing more flavor throughout.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Transfer half of the mixture to your prepared baking dish, then sprinkle with half of both cheeses. Add the remaining pasta mixture and top with the remaining cheese. The layering of cheese creates pockets of melty goodness throughout the casserole.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Sprinkle the breadcrumbs evenly over the top of the casserole - these will create a delicious textural contrast to the creamy interior.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Bake in the preheated oven for 25-30 minutes, or until the cheese is melted and bubbly and the top is golden brown. If needed, switch to the grill (broiler) for the final 2-3 minutes to achieve the perfect golden top.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>Allow the casserole to rest for 5-10 minutes before serving. This resting period allows the casserole to set slightly, making it easier to portion and serve.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>Garnish with freshly chopped parsley before serving. For an authentic cheeseburger experience, consider offering small bowls of typical burger accompaniments like diced pickles, extra ketchup, or mustard for people to add as desired.</li></ol>
