Step 1

Preheat the oven to 425 degrees F. Toss the squash with the olive oil, salt and pepper. Spread it on a baking sheet and roast until tender and slightly caramelized on the edges, about 20 to 25 minutes.

Step 2

While the squash is roasting, cook the pasta according to the directions. When finished, you can run it under cool water to stop it from cooking and also give it a quick spray of olive oil, tossing it, to keep it from sticking together.

Step 3

Reduce the heat in the oven to 375 degrees F. Spray a 9x13 inch baking dish with nonstick spray.

Step 4

Place the squash, tomatoes and garlic in a blender or food processor. Puree until smooth and creamy. Transfer the mixture to a large saucepan or skillet (make sure it’s large enough to add the ziti!) and add the milk. Heat over medium-low heat, stirring often.

Step 5

Once the squash mixture is warmed, stir in most of the cheese. Add in small handfuls and stir until completely melted before adding more. I like to do about three quarters of the cheese, saving some for the top. Once the cheese is all melted, taste the sauce and season it more if needed. I like to start with 1/4 teaspoon of salt and pepper if needed.

Step 6

Add the ziti to the squash sauce and toss well. Transfer all of the ziti into the baking dish. Scoop the ricotta in between the ziti - I like to do spoonfuls folded between the pasta all throughout the dish. Top the ziti with the remaining cheese. Top with the breadcrumbs.

Step 7

Bake for 35 to 40 minutes, until golden and bubbly on top. Serve!
