Step 1

Preheat oven to 350° F/180° C. Generously oil a 9"/23 cm square pan with sides about 2"/5 cm with 1 tablespoon of the oil. See note.

Step 2

Boil water in the large pot and cook the noodles to al dente. This generally takes only about 5 minutes. When done, rinse the noodles with cold water in the colander and set them aside.

Step 3

While the water is boiling for the noodles (or while the noodles cook), heat the remaining 2 tablespoons of olive oil. Add the sliced onion and cook slowly on medium low heat for about 10-12 minutes until beginning to turn golden brown. Stir occasionally with a silicone or wooden spatula. Then add the garlic and continue cooking for 45 seconds - 1 minute. Set aside.

Step 4

Mix the dairy ingredients, Worcestershire and hot sauces, half the cheese, and the onion. Stir. Add the noodles and stir until well combined.

Step 5

Pour the thick mixture into the oiled pan and sprinkle the remaining cheese on top. Bake 35-45 minutes, until the top begins to brown.
