1-First Steps: Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish or line it with parchment for easy cleanup. Bring a large pot of salted water to a boil and cook 8 oz (225 g) elbow macaroni until just al dente, about 6 7 minutes, then drain and rinse under cold water.

2-While the pasta cooks, finely chop 1 small onion and mince 2 cloves garlic. For adaptations like vegan or gluten-free, use plant-based pasta or gluten-free elbows as needed. This prep work sets the foundation for the rest of the recipe.

3-Browning the Protein: In a large skillet, heat 1 tbsp oil over medium heat and cook 1 lb (450 g) ground beef until browned, about 6 8 minutes. Season with 1 tsp salt, 1/2 tsp black pepper, and 1 tbsp Worcestershire sauce. Drain excess fat if using lean proteins, or sauté plant-based crumbles until warmed.

4-Making the Cheese Sauce: In a medium saucepan, melt 2 tbsp butter over medium heat. Whisk in 2 tbsp all-purpose flour and cook for 1 2 minutes. Gradually add 1/2 cup (120 ml) milk and another 1/2 cup (120 ml) milk or stock, simmering until thickened. Stir in 2 cups shredded cheddar cheese until smooth.

5-Combining and Baking: Mix the drained macaroni, browned meat, and cheese sauce in a large bowl. Add 2 beaten eggs (or flax slurry for vegan), 1/2 cup breadcrumbs, and 2 tbsp chopped parsley. Transfer to the baking dish and bake at 375°F for 40 45 minutes until golden.

6-Rest the casserole for 10 15 minutes before serving. This guide incorporates the provided directions, ensuring a hearty meal in about 1 hour and 15 minutes total.
