Add olive oil to a large skillet, heat to a medium-high heat.
Add the onions and garlic, and cook until soft.
Add the tomato sauce, Italian seasoning, sugar, salt and pepper.
Bring to a boil then turn heat down to a simmer until the sauce reduces down a little.
Remove from heat and stir in the cream and parmesan.
Add the cooked pasta to the skillet and toss for a few minutes. The sauce should cling to the pasta.
Divide up into bowls, and grate parmesan over the top.
Devour.
Notes
When you drain the pasta save a little of the cooking water to thin your sauce out if needed.Garnish with fresh basil if you're feeling fancy!Substitutions/AdditionsAdding a pinch of red pepper flakes is awesome in this pasta sauce.You can use diced tomatoes or crushed tomatoes instead of pureed, your sauce will be a little chunkier though.You can use any type of cooked pasta! I suggest Ditalini (little round tubes), Penne, Spaghetti, Fettuccine, Cappellini or Cavatappi.What to serve with pasta?I love garlic knots, an arugula salad or some steamed vegetables.
