This pasta casserole is so rich it feels like a million bucks. Cooked spaghetti is layered with a creamy combination of ricotta, cream cheese and Parmesan and then topped with a savory meat sauce featuring a mix of beef and sweet Italian sausage and a final layer of ooey-gooey mozzarella. The result: A dish that tastes like deliciously meaty lasagna but twirls on your fork like spaghetti. It’s both comforting and a little luxurious, a perfect dish to bring to a potluck or to make ahead for a crowd.
Ensure all dairy and egg are at room temperature for the cheese sauce; this prevents clumping and creates a smoother, more homogenous mixture. When browning the beef and sausage, resist the urge to stir constantly; allowing the meat to develop a good crust before breaking it up will enhance its flavor significantly through the Maillard reaction. Cook the spaghetti strictly 'al dente' as it will continue to cook and absorb moisture in the oven, preventing a mushy texture. Lastly, the resting period after baking is crucial for the casserole to set, making for cleaner, more presentable servings.
