Butternut squash, garlic, and onion are roasted and blended with vegetable broth. Brown butter, white wine, and fresh herbs give this sauce an amazing depth of flavor. Finish with salty, nutty grated Pecorino Romano cheese and toss with your choice of pasta. Take this dish to the next level by topping it with crispy sauteed mushrooms, bacon, or Italian sausage (optional but recommended)!
