This casserole is luscious and super-creamy. It makes a great side dish or meatless main meal. Spaghetti squash is an excellent alternative to pasta and makes for a hearty and satisfying veggie-packed dish. Thanks to its neutral taste, think of the winter squash as a blank canvas you can embellish with your favorite ingredients. Switch up the flavor profile by swapping crumbled feta for the mozzarella and fresh dill for the basil. Add some protein by topping your portion with a poached or sunny side-up egg. We’ve microwaved the squash for ease in prep, but you could also roast it the oven if you prefer.

Extra virgin olive oil
