Potato casserole is one of those dishes for which appearance is very important.
If the food doesn't look appetizing, it's unlikely to be popular with guests.
And the hostess will be very upset. After all, an unsuccessful appearance does not always indicate that the casserole is really tasteless.
However, it is very easy to prevent failure. To do this, it is enough to properly "process" the surface of the dish before placing the filled baking dish in the oven.
What to grease the casserole with
You will need the most common chicken egg. The top layer of the casserole should be covered with a mixture of raw egg white and yolk.
But that's not all. The casserole needs to be sprayed with vegetable oil. You can use a special sprayer for this.
There is one more desirable action. The future dish should be sprinkled with breadcrumbs.
After baking for half an hour, you will get a casserole that is not only tasty, but also looks appetizing.
The crispy, golden-brown crust will attract the attention of all household members and guests sitting at the festive table.
