Vidalia Onion Pie
serves 8
Vidalia onions are Georgia's most famous taste. This sweet onion is grown in southeast Georgia (Vidalia, GA), just a few miles west of Savannah. They can be stored in a cool dry place to use throughout the year.

3 Cups thinly sliced Vidalia onions
3 Tbs. butter, melted
One 9-inch prebaked deep dish pie shell
1/2 cup milk
1 1/2 cups sour cream
1 tsp. salt
2 eggs, beaten
3 Tbs. all purpose flour
4 slices bacon, fried crisp and crumbled

Preheat oven to 325 degrees. Saute onion in butter until lightly browned. Spoon into pie shell. Combine milk, sour cream, salt, eggs and flour. Mix well and pour over onion mixture. Garnish with bacon. Bake for 30 minutes or until firm in center. Pie has taste and texture of a quiche.

Mona's Notes: I couldn't find true Vidalia onions in town so I used sweet onions.

This is really a great dish. Brad took one bite and said it was great, of course we are tremendous onion fans. It was really simple to make, just a few tears were shed during the slicing of that many onions and the sauteing caused a little eye irritation. I had a very little bit of bacon fat left in the pot after crisping the bacon, so I left it in along with the butter to saute the onions in. This would be a very good dish to bring to a pot luck type of dinner too. Definitely a repeat performer at our house! Yum.

The texture is definitely quiche like, but the taste is like super cheesey! must be the sour cream?
