- 2 tablespoons olive oil
- 3 cloves garlic, minced
- 1 medium to large white onion, diced
- 1 (29 to 32-ounce) can crushed tomatoes
- 1/4 cup finely chopped parsley leaves, plus about 12 small sprigs to garnish
- 1/2 teaspoon dried marjoram, or 1 teaspoon finely chopped fresh marjoram
- 1/2 teaspoon dried thyme, or 1 teaspoon finely chopped fresh thyme leaves
- 1/4 cup cornstarch
- Salt and freshly ground black pepper
- 1 (16-ounce) package penne pasta
- 1/2 stick (2 ounces, or 1/4 cup) butter, cut into chunks
- 4 ounces cream cheese, cut into chunks
- 1 large ripe tomato, diced
Bring a pot of salted water to a boil for the pasta.
Heat olive oil over medium-high heat in a medium saucepot, and saute garlic and onion until the onions become translucent, being careful not to burn them. Add crushed tomatoes, fresh parsley, marjoram and thyme. Create a slurry by gradually whisking cornstarch into 1/2 cup water. Add the slurry to the sauce to thicken and season, to taste, with salt and pepper. Bring to a boil, then reduce heat to low, cover and simmer about 20 minutes, checking periodically to make sure the sauce doesn't burn.
Remove the sauce from the heat, and whisk in butter and cream cheese. Add the boiled pasta to the sauce and gently fold in along with the diced tomatoes. Transfer to serving dish and garnish with fresh parsley.
