Swapping heavy cream for half-and-half in this baked casserole introduces excess water that prevents the dairy proteins from coagulating into a stable custard. Achieving the correct thermal density requires understanding how high-fat dairy interacts with whipped eggs during the secondary 20-minute bake at 350 degrees Fahrenheit. Without a minimum of 36 percent butterfat content from heavy cream, the custard separates, leaving a watery pool at the base of the casserole dish instead of a velvety binder.
Brussels sprouts contain high levels of sulfur compounds that release pungent aromas when overcooked. Roasting them cut-side down in olive oil at 400 degrees Fahrenheit for 20 minutes caramelizes the exterior sugars via the Maillard reaction, neutralizing bitter notes before the vegetables encounter the dairy. Salting the sprouts prior to this initial roast draws out surface moisture, allowing the olive oil to conduct heat efficiently against the sheet pan.
Selecting cheeses with low moisture content prevents unwanted greasiness as the fats render under broiler heat. Sharp cheddar melts smoothly due to its emulsified protein structure, whereas aged varieties like parmesan demand a 1:1 grating ratio with a high-moisture melting cheese like mozzarella to avoid clumping. Storing leftovers in an airtight container within the refrigerator for up to three days preserves the structural integrity of the bacon crumbles, though reheating should occur gently in a 300-degree oven to prevent the cheese oils from breaking.
