Bring a pot of water to boil.
While the water is boiling, start on the sauce. In a pan that will be large enough to fit the sauce and the cooked pasta, over medium heat, add olive oil.
When olive oil is hot, add diced onion. Let onion cook until fragrant and golden, a few minutes.
Add the sausage that have been removed from casings to the pan, and with a wooden spoon, separate them into small pieces.
Let them brown, a few minutes.
Add white wine, and let the alcohol evaporate off.
Cover with a lid and let the sausages finish cooking, about 5-10 minutes.
At this point, the water should be boiling and you can throw your pasta in depending on how long it takes to cook.
Once the sausages are cooked through, add the whipping cream to the sauce. Let it warm through, and adjust for salt and pepper.
Add the pasta to the pan with the sausages and cream, and stir with a wooden spoon - let the pasta absorb the sauce.
Add pasta water if sauce is too thick.
Add pecorino romano and stir once more.
Plate, top with more pecorino and enjoy!
