A simple, fuss-free casserole perfect for busy mornings and special occasions like Father’s Day. Prepped overnight for a creamy, flavorful breakfast with layers of bread, eggs, cheese, and savory sausage or veggies.
Use day-old bread for best texture. Room temperature eggs mix more evenly. Let casserole rest after baking for easier slicing. If casserole is too wet after baking, bake an additional 5-10 minutes. Vegetarian and gluten-free substitutions are easy. Butter the baking dish well to prevent sticking.
