This is the perfect recipe if you are looking to switch up your basic tomato based pasta sauce for something new and seasonal. It’s a super flavorful and creamy texture that pairs perfectly with shell pasta that just scoops up all the flavor in every bite. Roasting the squash gives a rich deeper flavor that pairs well with the Italian seasoning.

I like to freeze half of the sauce for later when I make this recipe. It thaws and reheats perfectly; just add some water if it seems to have thickened up.

Parmesan is the garnish for this pasta. The sharp saltiness of the cheese brings out the natural flavor of the squash even more!

If you’re looking to add a protein to this dish, I recommend some grilled or steamed chicken. Cook up some chicken with some some more Italian seasoning and eat it on the side or mix it right into the pasta!

Tips and Tricks

  • If your mix isn’t turning out smooth enough, add some of the water that your pasta boiled in or olive oil to thin it out.
  • Always be careful when blending something hot. Pressure can build up inside the closed blender and in some cases can even force the lid off mid-blend! For this recipe we are blending a bunch of roasted ingredients right out of the oven. To be safe, I recommend opening the top of your blender and place a towel over it while it blends. This takes away the danger of pressure building up while making sure you don’t make a mess from blending with an open blender!
