Variations: Add crispy bacon for smoky flavor, swap in Gruyère and Parmesan for a three-cheese luxury version, stir in sautéed jalapeños for gentle heat, or fold in diced ham for a hearty main dish. Troubleshooting: Avoid curdling by letting pasta cool before adding custard; prevent dryness by keeping the egg-to-dairy ratio generous. Make-ahead: Assemble a day in advance, refrigerate, and add 15–20 minutes to bake time. Storage: Keeps 3–4 days refrigerated, reheats best covered in the oven at 325°F. Scaling: Double easily in two dishes or a roasting pan for large gatherings.
