Ingredients

Why this recipe works

The method of layering dry pasta directly with the sauce allows the noodles to absorb the flavors as they cook in the oven. This technique ensures the pasta remains perfectly al dente while becoming infused with the creamy sauce throughout the baking process.

Using a wide, shallow baking dish increases the surface area for the crumb topping. This maximizes the amount of golden, crunchy texture in every serving, which is the hallmark of a great tetrazzini. The even distribution of heat ensures the casserole cooks uniformly from edge to center.

Notes and substitutions

Choose a high-quality creamy white sauce or a classic béchamel to serve as the foundation of this dish.

The sauce should be thick enough to coat the pasta but thin enough to allow for proper hydration during the baking time. Ensure the ham is diced into uniform cubes for even distribution.

The choice of buttery crackers significantly impacts the final crust. Classic round buttery crackers are ideal, but any high-fat cracker will provide the necessary richness.

Ensure the baker is deep enough to prevent the sauce from bubbling over while providing enough space for the ingredients to expand.

• cooked ham: Use leftover shredded rotisserie chicken or diced turkey breast as a lean alternative for the ham.
• buttery cracker crumbs: Substitute with panko breadcrumbs mixed with two tablespoons of melted butter for a similar crunchy texture.
