Creamy One-Pot Tortellini Soup

Creamy Tortellini Soup combines refrigerated cheese tortellini with a rich, cheesy tomato and basil broth, brightened with garlic and spinach. This vegetarian, one-pot meal comes together in about 15 minutes, making it perfect for busy weeknights or a comforting lunch.

I always keep a bag of refrigerated cheese tortellini on hand because it cooks quickly and transforms into an effortless, satisfying meal. In this recipe the tortellini are simmered in a smooth tomato sauce enriched with cream and Parmesan, finished with fresh basil. The result is a cozy, flavorful soup that feels indulgent but is fast to prepare.

This recipe is intentionally simple and flexible: make it strictly vegetarian or add sausage or meatballs if you prefer. It’s a reliable weeknight favorite that reheats well for lunches, and the fresh spinach adds color and a boost of nutrients.

Ingredients

Below are the ingredients that create the base and flavor for this creamy tortellini soup. Quantities and complete measurements appear in the recipe card further down.

• Olive oil – for sautéing the aromatics.
• Onion – diced for a sweet, savory base.
• Garlic – minced to add depth and aroma.
• Spinach – fresh baby spinach or frozen chopped spinach both work. Use about 4 cups fresh, or one 16-ounce bag frozen (thawed and squeezed dry).
• Crushed tomatoes – canned crushed tomatoes create a smooth, rich tomato base. Diced tomatoes can be used instead for a chunkier texture.
• Tomato sauce – adds body and a consistent tomato flavor.
• Vegetable broth – keeps the recipe vegetarian. Chicken broth may be substituted if desired; reduce added salt when using a regular broth.
• Italian seasoning – a blend of dried herbs that brings classic Italian flavor; use a store-bought mix or your own blend.
• Cheese tortellini – refrigerated fresh cheese tortellini is recommended. If frozen, add one minute to cooking time; dried tortellini will require longer and should be cooked according to package directions.
• Heavy cream – for a silky, creamy finish.
• Parmesan cheese – freshly grated for the best flavor and melt-in-your-mouth texture.
• Fresh basil – torn or chiffonaded as a bright finishing garnish.

Instructions

The method is straightforward and designed for speed: sauté, simmer, add the tortellini, then finish with cream and cheese. Follow the numbered steps below for a quick 15-minute meal.

1. Heat the oil and cook the aromatics. In a large pot or Dutch oven over medium-high heat, warm the olive oil. Add the diced onion and sauté for about 4 minutes until softened. Stir in the minced garlic and spinach and cook another 1–2 minutes until the spinach wilts.
2. Build the tomato base. Pour in the crushed tomatoes, tomato sauce, and vegetable broth. Stir in the Italian seasoning and bring the mixture to a gentle simmer so flavors meld.
3. Cook the tortellini. Add the refrigerated cheese tortellini to the simmering soup and cook for 3–4 minutes, or 1 minute longer if the tortellini were frozen. If using dried tortellini, follow package timing and allow additional simmering.
4. Finish with cream and cheese. Stir in the heavy cream and grated Parmesan. Allow the soup to simmer another 1–2 minutes so it thickens slightly and the cheese melts into the broth.
5. Serve. Remove from heat, ladle into bowls, and top with fresh basil. Serve immediately with crusty bread or a green salad.
