In an oven-proof pan over medium-high heat, add the sausage and cook, breaking up with a spatula, until browned, about 8 minutes. Remove from pan and set aside.
Add the butter to the pan. When melted, add the onions and butternut squash. Saute, tossing occasionally, until the butternut squash is soft, about 8 minutes.
Add the sausage back to the pan.
In a bowl, beat the eggs together with the cream, salt and pepper. Pour the eggs over the vegetables in the pan and cook until the edges are set, about 5 minutes.
Sprinkle the shredded cheese over the top. Transfer the pan to the oven and cook for 7 minutes, or until the center of the eggs are set.
