This easy ravioli sauce is rich, flavorful, creamy, and tomatoey. It's so delicious and comes together in only 30 minutes. You can use it for non-ravioli pasta dishes as well!
In a medium pot, heat the olive oil over medium-high heat. Add the onions and garlic, and cook for 4-5 minutes until the onions are soft and translucent.
Add the tomato paste and cook for 1 minute.
Add the chicken stock, diced tomatoes, sugar, Italian seasoning, salt, and black pepper. Bring to a boil, then reduce to a simmer and cook for 15-20 minutes.
Stir in the heavy cream and cook for 2 more minutes.
