Bring a big pot of water up to a boil for your pasta.
Slice up some onions and garlic and toss them into a pan with a little bit of olive oil.
Once your onions and garlic are softened, add a little bit of tomato paste.
Cook the tomato paste down in your onions a little bit.
Add some cream and a little salt and pepper.
Whisk it all together and let it cook down by about ⅓ until it's nice and thick and saucy.
Taste for seasoning.
Add some Parmesan cheese and your pasta, along with a little splash of the starchy pasta water.
