Step 4
Pour the mixture into the prepared dish, spreading it evenly. If desired, add a sprinkle of brown sugar on top for a caramelized finish.
Step 5
Bake for 35-40 minutes or until the top is golden and the center is set. Let it cool slightly before serving.
Storage Options
Leftovers can be stored in an airtight container in the refrigerator for up to five days. For extended storage, freeze portions in individual containers for up to three months. Reheat in the oven or microwave until warm before enjoying.
