Creamy butternut squash pasta shells stuffed with spicy Italian sausage, fresh spinach, and cherry tomatoes, topped with pepper jack cheese and baked until bubbly. This cozy fall comfort food features a rich butternut squash and heavy cream sauce.
For a dairy-free version, substitute coconut milk for heavy cream, but pepper jack cheese may need a dairy-free alternative. Use pumpkin puree if butternut squash is unavailable. Make ahead by preparing filling and sauce separately; assemble and bake when ready.
