Eggs perform the primary structural work in this formulation. As thermal energy transfers through the baking dish, egg proteins coagulate to form a solid matrix that binds the loose oats together. Visual cues dictate doneness here rather than internal temperature probes. Look for the edges to pull slightly away from the sides of the 9 x 13-inch pan. The center should offer firm resistance when pressed lightly with a fingertip, lacking any liquid shimmer. Baking for 35 to 40 minutes at 375 degrees Fahrenheit allows moisture evaporation to concentrate the sugars without scorching the dairy solids present in the butter and milk.
Fresh strawberries and bananas introduce distinct moisture levels compared to dehydrated counterparts. High water content in fresh produce releases steam during the bake, which hydrates the surrounding starches. This localized moisture prevents the oats from drying out. Preserved or dried fruit absorbs liquid rather than releasing it, requiring adjustments to the surrounding dairy ratios. Fresh strawberries also contain natural pectin, which thickens the surrounding juices as temperatures rise, yielding a cohesive casserole rather than a loose porridge.
