Common Questions
Can I make this ahead of time?
Yes, you can assemble the entire dish the night before. Cover it tightly and store it in the refrigerator. Bake it in the morning for an easy breakfast.
How do I know when it is done?
The center should feel firm and not jiggle when moved. The top will be a beautiful golden brown color. Let it rest so the custard sets fully.
Can I use frozen vegetables?
Fresh veggies work best for the right texture and moisture. If using frozen, thaw and drain them completely first. This prevents the casserole from becoming too watery.
I hope this hearty bake brings a little extra joy to your morning table. It is the perfect way to gather everyone together for a delicious meal. Happy cooking!
