My mom has been making this for years since adapting it from The Good Housekeeping Cookbook "Eleven-Layered Casserole" (who would think that would be the name of the best mac&cheese ever?) from 1963, edited by Dorothy B. Marsh. Here is her adapted recipe:
Ellen's Macaroni & Cheese
Ingredients:
8 oz. elbow macaroni, cooked
2 cups shredded cheddar cheese
1/2 tsp. salt
1/4 tsp. pepper
1/2 tsp. oregano
almost all of 1 can of evaporated milk (or about 9 oz.)
1 small onion, sliced (for flavor, not necessarily to eat)
about 1/4 cup parmesan cheese, grated
Directions:
1. Pre-heat oven to 375 degrees.
2. Layer ingredients as follows:
1/2 macaroni
1/2 cheddar cheese
1/2 onion slices
1/2 spices
1/2 evaporated milk
3. Repeat
4. Top with parmesan cheese
5. Cover and bake for 20 minutes
6. Uncover and bake for additional 10 minutes
7. Enjoy the tastiness!
