Pre-heat oven to 450 degrees F.
In a large bowl, toss together butternut squash, onions, garlic, olive oil and spices until well-coated.
Spread veggies out on a baking sheet and bake for about 25 minutes.
While the veggies are roasting, prepare your pasta in a dutch oven to finish at about the same time as your veggies.
Reserve 1/4 cup of pasta water and drain the pasta. Return pasta and reserved water to dutch oven. Add in 2 generous handfuls of baby spinach and roasted veggies. Toss gently and cover for a couple minutes to help spinach wilt.
Served topped with parmesan cheese and basil. Enjoy!
