Ingredients

Why this recipe works

The method of simmering the beef directly in the marinara sauce ensures that the meat absorbs all the flavors of the tomatoes and herbs. This creates a cohesive, rich foundation for the casserole, preventing the meat from feeling like a separate element. By using jumbo pasta shells, you create little vessels for the sauce to hide in, ensuring every forkful is perfectly balanced with sauce, meat, and tender pasta.

Baking the assembled dish in a glass container allows for even heat distribution, which is essential for achieving a perfect golden crust without drying out the pasta.

The combination of mozzarella and cheddar is strategic: mozzarella is prized for its meltability and stretch, while cheddar provides the necessary fat and flavor depth to balance the acidity of the marinara. This pairing ensures the final dish is visually appealing, aromatic, and perfectly browned.

Notes and substitutions

For the best results, use a high-quality marinara sauce that has a balance of sweetness and acidity. If the sauce is too thick, add a quarter cup of water or beef broth to loosen it before pouring it into the baking dish. The ground beef should be lean enough to avoid excess grease but fatty enough to provide flavor; an 85/15 or 90/10 blend is ideal for this type of baked pasta dish.

A standard glass baking dish works best for this recipe because it holds heat well and presents beautifully. Ensure the oven is fully preheated before putting the dish inside to ensure the cheese melts quickly without the pasta becoming overcooked.

If you prefer a crunchier top, you can place the casserole under the broiler for the last minute of cooking, but watch it very closely to prevent the cheese from burning or becoming rubbery.
