Add evoo and red onion to a sauté pan. Cook until slightly soft, 1 to 2 minutes.
Add garlic and sauté for 30 seconds. Add butternut squash, stock, sage, and thyme. Stir and cover. Cook until butternut squash is fork tender, 8 to 10 minutes.
While squash is cooking, bring a large pot of water to a boil. Add pasta and cook, 8 to 10 minutes, drain and place in a large serving bowl.
When squash is tender, add everything into a food processor along with the coconut milk and salt to taste. Puree until smooth.
In the meantime, heat a small skillet to medium-high heat and add duck cherry sausages. You can put them into the oven if you prefer, but I just heat them up. Cook 4 to 5 minutes.
When pasta is done and butternut squash alfredo is smooth, add alfredo to pasta and lightly toss. Slice sausages and serve on top of pasta.
