Step 1

Dice the onion. Mince the garlic.

Step 2

In a large pot or Dutch oven, heat the olive oil. Add the onion and sauté for about 5 to 6 minutes until translucent. Add the garlic and sauté 30 seconds more.

Step 3

Add the crushed tomatoes, tomato paste, broth, herbs and kosher salt. Bring to a simmer and simmer for 8 minutes.

Step 4

Stir in the spinach, basil leaves, heavy cream and Parmesan cheese. Bring to simmer and add the tortellini. Cook according to the package instructions: about 2 to 3 minutes for refrigerated and 3 to 5 minutes for frozen. Taste and add additional salt as desired (we added another 1/4 teaspoon). Serve immediately.

Step 5

Make ahead and storage: Store leftovers refrigerated. The pasta does soak up quite a bit of the broth, so you may want to add a splash of water when reheating. If you make it ahead, we recommend making the soup without the tortellini; then heat it up and cook the pasta right before serving.
