This is a simple recipe from the 70s that turns up in quite a few old spiral-bound church cookbooks.
For some reason, I only think to make it during Christmas/New Years'.
French's Fried Onion Quiche
1 9-inch deep-dish pie crust
1 1⁄2 cups shredded cheese swiss, cheddar, a blend, etc...
1 (3 ounces) can French-fried onions
3 eggs slightly beaten with a fork
1 1⁄2 cups milk, evaporated milk, or part heavy cream
Salt and pepper to taste and a big pinch of cayenne pepper
Preheat oven to 375-400 and par-bake pie shell for 5 minutes. Add the grated cheese and onion rings to the pie shell. Combine eggs milk and seasonings, pour over the other ingredients, and bake for 45-50 minutes until a knife inserted in the center comes out clean. Let stand for 15 minutes and serve.
These days I skip the pie crust and bake it in a round non-stick cake pan that has been sprayed with PAM.
