Spaghetti squash is layered with tomato sauce and mozzarella, then topped with Parmesan before being baked. It's a delicious alternative to the classic pasta bake.
Is also known as spaghetti marrow. They can be found in speciality markets.
Parmesan cheese is not truly vegetarian, as it contains animal rennet. To make this dish 100% vegetarian, omit the cheese or find a suitable vegetarian substitute made without animal rennet. In supermarkets look for the 'parmesan style hard cheeses' which are suitable for vegetarians.
This is great! I added 1 lb. sausage, omitted the olives, substituted chicken bouillon for vegetable bouillon, and substituted Romano cheese for Parmesan. I put in a 9x13 baking dish (much easier to prepare and serve out of than the shells) and made each layer (sauce w/ sausage, spaghetti squash strands, and cheese on top) twice. Yum! - 05 Mar 2006 (Review from Allrecipes US | Canada)
So tasty! To cut down cooking time, cut the spaghetti squash in half and place cut side down in a microwavable dish with a few tablespoons of water. Heat on high for 8-10 minutes. - 27 Sep 2007 (Review from Allrecipes US | Canada)
This is very good and healthy. I pureed the tomato and onion mixture with a hand-held blender and boiled it down for about 25 minutes to reduce much of the water. Next time I will nix the squash shells and opt for throwing it all in a baking dish - the shells are a nuisance. I also added a couple dashes of crushed red pepper for some heat. Oh, and it's just fine without the Parmesan. - 26 Sep 2002 (Review from Allrecipes US | Canada)
