Evaporated milk does the heaviest lifting in this recipe by providing concentrated dairy solids without introducing excess water that causes separation during prolonged heating. Skim evaporated milk works identically to whole varieties in protein structure, preventing the custard from breaking while simmering. Par-cooking the pasta for exactly five minutes leaves the interior firm, ensuring the tubes absorb excess liquid without dissolving into starch paste as the slow cooker cycles through its heat phases.
Whisking the eggs, milk, melted butter, and seasonings thoroughly before adding the solids ensures uniform coagulation. Pouring cold butter directly into chilled eggs causes solidification, so cool the fat to room temperature first. Cooking starts at high heat for 30 minutes to jumpstart the thermal transfer, then drops immediately to low for two to two and a half hours. Watch for a set center to signal doneness.
Freshly shredded blocks melt more smoothly than pre-bagged alternatives dusted with cellulose powder. Preserved cheeses rely on anti-caking agents that hinder emulsion formation in slow-cooker custards. Sautéing breadcrumbs separately in olive oil just before serving adds necessary crunch to offset the soft, rich pasta beneath.
