Spaghetti Squash and Kale Casserole

Spaghetti squash and kale casserole- Ginger and Toasted Sesame

I was really excited about it becoming cooler last weekend but the weather suddenly became incredibly hot for October, peaking in the upper 80s. Today as I prepared this casserole, between the sautéing and the broiler on high I was sweating profusely and wiping my brow between photo set ups. Although fall hasn’t really arrived yet it doesn’t mean that one can’t enjoy some fall produce. Perhaps I can will autumn to start by eating a lot of squash…

This dish has been on regular rotation at dinner time because it’s simple to make and delicious. The creamy ricotta and sour cream combined together make it seem rich but it’s balanced out by the healthy strands of spaghetti squash and the sautéd kale. A crust of salty pecorino romano lends nice flavor and texture to finish the dish.

Some cut the squash in half and roast it in the oven but I prefer to poke a few holes in the squash with a knife and roast it whole. I always get anxious cutting a winter squash, so I prefer to roast it first to make it easier to handle. After roasting the squash, remove the seeds and use a fork to separate the strands of squash. A quick sauté of the onion and kale, a quick stir with the squash and ricotta cheese will be all the active prep needed for the casserole. Top with the cheese, bake for 20 minutes and broil to brown the cheese.

This dish is perfect as a side for a pot roast or a some grilled chicken, but I also like to take leftovers to work as a main dish with a side salad. It reheats beautifully and could also be pre-assembled ahead of time if you are planning to have people over with several dishes to prepare.

    I’ve never seen this type of squash before! I love the sound of this dish and will try to make it if I can find some spaghetti squash at my local grocer’s :)

      It’s a large, yellow, oval shaped squash and it can get pretty big. Some people even prepare it in pasta-like dishes once they separate the strands with a fork. It’s tasty :)

    I love spaghetti squash and use it as a pasta substitute! This recipe looks great, could I use spinach instead of kale?

      I just saw your spaghetti squash pad thai (via your food blogger resource page about food sharing sites) and it looks so delicious! I am definitely going to try that recipe soon!
