  1. Preheat oven to 425 degrees F (220 degrees C). Grease a 9x13-inch casserole dish.

  3. Lightly whisk eggs in a bowl; stir in sour cream, Parmesan cheese, basil, and black pepper. Pour egg mixture over squash mixture; top with mozzarella cheese.
  4. Bake in the preheated oven until squash is tender and mozzarella cheese is bubbling, about 30 minutes.

This is a very delicious way to cook butternut squash! Next time I think I will cook it at 375 or take it out of the oven sooner. Since I love nutmeg, I might add just a bit. :)

definitely had a quiche texture, was not expecting that. Added extra salt as well

Never cooked or eaten butternut squash before. This was wonderful. Took a little longer than I thought to peel and cook squash, though. If a person doesn't have "experience" with this type of squash, they might want to take a little extra time for prep.

This was the first time my family and I had eaten butternut squash and it was great! Kids and husband loved it! I was out of sour cream, so I used about a half a cup of goat cheese, and instead of the fresh basil, I just sprinkled some dried basil in. To make it easier to peel the squash, I put it in the oven on Broil for 5 minutes. It softened the skin so that it peeled easily and was easier to cut without cooking the squash.

Very tasty meal. We had this with brown rice and a vinegary cole slaw salad. I made a few changes: I added beans to the squash and onions. I used cheddar instead of Parmesan. And I mixed the mozzarella with some ground flax seeds. My family requested that the next time I make this I have a bigger cheesy layer. So I'll probably just double that part of the recipe.

Fantastic!! I used feta cheese on top instead (used parmesan inside) and only had to use a 7x11 pyrex dish.

I thought this was a really creative way to use butternut squash. It was tasty. I added cubed chicken to make it a full meal. I cut the squash length wise and roasted it for 50 minutes at 400 degrees which made it much easier to handle.

Just made this recipe...I didn't have any mozzarella so I used other shredded cheese...Used low fat Greek yogurt in place of sour cream and it was very tasty...My husband loved it! We will have the leftovers for breakfast with crispy bacon...I agree with the other reviewer: It does take a while to peel and cut up the squash...Make sure you have a good sharp knife and cut the squash into bite size pieces if you don't have a food processor...
