Cooking lean white fish like cod in a rich dairy-based sauce requires managing moisture release to prevent the flesh from turning rubbery. Cod is composed of short muscle fibers called myotomes, which separate easily as proteins denature and tighten under heat. When submerged in a heavy liquid during baking, the thermal transfer rate changes significantly compared to dry-heat methods. Baking uncovered at 350 degrees Fahrenheit allows excess moisture from the zucchini and yellow squash to evaporate rather than pooling and diluting the sauce. Pureeing the roasted red peppers with garlic, basil, and olive oil before simmering creates an emulsified base that holds up to the addition of light cream and Parmigiano-Reggiano without breaking.
Proteins in cod begin contracting firmly at around 130 to 140 degrees Fahrenheit. Because the fish bakes atop a bed of squash matchsticks and underneath a blanket of dairy and pepper puree, it undergoes gentle, insulated cooking. The vegetables act as a thermal buffer, elevating the cod slightly off the bottom of the dish so circulating oven heat reaches all sides evenly. Removing the dish from the oven precisely when the internal temperature hits 135 degrees ensures the flakes remain opaque and juicy. If scaling the quantities up for a larger gathering, maintain the same layer thickness in the baking dish rather than crowding extra fillets vertically, which would drastically alter the 30-to-40-minute baking window.
