Preparation

Step 1

Preheat oven to 425°F. Toss butternut squash with olive oil and season generously with salt and pepper. Divide between 2 parchment-lined baking sheets. Roast, rotating trays halfway through, until tender and golden, about 40 minutes.

Transfer to a food processor along with ¾ cup milk, thyme, and ¼ cup water. Puree.

Make white sauce: Melt butter over ­medium heat in a medium saucepan, then whisk in flour and cook, whisking constantly, until tan, about 5 minutes. Slowly whisk in remaining 5 cups milk and cook, whisking, until thickened, about 10 minutes. Season with 2 tsp salt and ½ tsp pepper.

Spread about ½ cup white sauce evenly across bottom of a 9-by-13-inch baking dish. Top with 3 noodles. Dollop 1 cup squash over noodles and use the back of a spoon to carefully spread into an even layer, covering ­noodles completely. Top with 1 cup sauce, using back of spoon to spread evenly. Repeat the noodle, squash, and sauce layers 3 more times.

Arrange mozzarella slices on top and ­season with pepper. Cover with foil; bake 50 minutes. Increase heat to 475°F, remove foil, and bake until mozzarella is golden in spots, 5 to 10 more minutes. Let stand at least 15 minutes before serving.
