Spaghetti Squash Lasagna

If you're looking for a cholesterol-free, fat-free and gluten-free ingredient to add to your cooking repertoire, look no further than versatile spaghetti squash. The flesh of this unique squash, when cooked, comes out in strands - like spaghetti - and can be used in many ways.

Spaghetti squash is a great healthy substitute for regular spaghetti, especially if you're watching your carb intake. Once cooked, all it takes is a fork to pull up the long strands.  They can be removed from the shell and tossed with a number of different ingredients like butter and Parmesan cheese, marinara sauce, Alfredo sauce, feta cheese with Kalamata olives, tomato and basil, cooked ground beef, ground turkey, sausage and different cheeses and herbs. The combinations are endless. The strands can also be left in the shells and topped with sauces, with or without meat and cheese.

This Spaghetti Squash Lasagna is a good example of a stuffed squash recipe. The squash is roasted and then the strands are pulled up before the squash is stuffed with meat, sauce, cheese and seasonings, and put back in the oven to bake a bit longer.

The homemade sauce used in this recipe is excellent, but your favorite marinara or store-bought spaghetti sauce will also do the trick.

Learn how to easily cut a spaghetti squash, by checking out our easy step-by-step infographic. But, before you start it's a good idea to microwave the squash before cutting to make it a bit easier. Pierce the skin with a 4" Paring Knife to allow it to vent while in the microwave. Once it has softened a little, let it cool and use a Butcher Knife to cut the squash in half.
