Are Egg Noodles and spiral pasta the same Thing?

The answer is no. Whilst egg noodles and spiral pasta are very similar, spiral pasta tends not to be made from egg. Noodles on the other hand have much more egg in them and the spiral shape makes them great for casseroles and stews.

If you have an egg allergy, you can switch out the egg noodles for an egg free spiral based pasta.
