Pour the mixture into a greased casserole dish. Spread it evenly, allowing every bite to soak up the delicious flavors and ensuring an even cook.
Sprinkle breadcrumbs on top, if desired. This optional touch adds a delightful crunch that contrasts perfectly with the creamy filling, enhancing every mouthful.
Bake in the preheated oven for 30 minutes, or until heated through and the top is golden brown and bubbling. You’ll know it’s ready when the aroma fills your kitchen—pure comfort!
