Can I be honest with you?  I think I may have cracked the spaghetti squash code with this spaghetti squash casserole recipe.

I made this dish on a Wednesday of last week, and then made it all over again. The honest part is that I was never the biggest fan of spaghetti squash. I’ve made recipes with it before, but this one busted to the top of my all time favorite Fall dishes.

Italian sausage, mushrooms, onions, sage, thyme, pecorino Romano and a splash of heavy cream come together to bring one of the best Italian comfort dishes of the season and it’s still low-carb!

I talk to you all the time about my favorite Pecorino Romano cheese and why I love it so much. It’s a sheep’s milk cheese that has a salty tang, and can be used interchangeably with Parmesan Cheese.

Spaghetti squash tastes best when it is properly softened. This squash is twice baked and tender.

Each bite delivers a moment of comfort with the flavors of the sausage with the grated cheese, the earthiness of mushrooms and slight sweetness of the squash, all pulled together by heavy cream.

Spaghetti Squash Casserole Roasted and Rebaked

The spaghetti squash is roasted and then rebaked in a casserole. This also happens to be a very pretty dish that makes a beautiful presentation if you decide to put it back into the shell of the squash.

    I’ve been cooking more recipes with spaghetti squashthis past year and my husband loved this one…his favorite so far.

    I made this recipe for my husband and me for dinner tonight. I was absolutely wonderful! My husband doesn’t like mushrooms and will pick them out of everything ate every one and didn’t complain once. I wish there was an easier way to prepare the spaghetti squash because that’s the only drawback but the final result is well worth the extra trouble.
