For Assembly:

The Step-by-Step Method: Building Layers of Goodness
Prep Time: 30 mins | Cook Time: 25-30 mins | Serves: 6-8

Step 1: Cook the Pasta
Bring a large pot of generously salted water to a boil. Cook the Stellini pasta according to package directions until al dente (firm to the bite). Drain and rinse with cool water to stop the cooking process. Drizzle with a little olive oil to prevent sticking.

Step 2: Build the Meat Sauce
In a large skillet over medium-high heat, brown the ground beef, breaking it up with a spoon. Drain any excess grease.
Add the diced onion and cook for 4-5 minutes until softened. Add the garlic and cook for 1 more minute until fragrant.
Stir in the marinara sauce, oregano, and red pepper flakes. Simmer for 10-15 minutes to allow the flavors to meld. Season with salt and pepper.

Step 3: Create the Luxurious Béchamel
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes, until it forms a smooth paste (a roux) and smells slightly nutty.
Gradually pour in the warm milk, whisking constantly to prevent lumps.
Continue to cook, whisking, until the sauce thickens enough to coat the back of a spoon (about 5-7 minutes).
Remove from heat and stir in the nutmeg, salt, and white pepper.

Step 4: The Grand Assembly
Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish.
In a large bowl, combine the cooked Stellini pasta with the meat sauce and half of the béchamel sauce. Stir until everything is evenly coated.
Pour this mixture into the prepared baking dish and spread it evenly.
Pour the remaining béchamel sauce over the top and spread it into a smooth layer.
Sprinkle the shredded mozzarella and grated Parmesan cheese evenly over the top.

Step 5: Bake to Bubbly, Golden Perfection
Bake, uncovered, for 25-30 minutes, or until the cheese is completely melted, bubbly, and has golden brown spots.
If you desire a more deeply browned top, broil for the final 1-2 minutes (watch closely!).

Step 6: The Crucial Rest
Remove the casserole from the oven and let it rest for 10-15 minutes before serving. This allows the sauces to set, making it easier to slice and serve neatly.
Garnish with fresh basil or parsley before serving.
