Chicken Pesto Tortellini Soup

This Chicken Pesto Tortellini Soup is chunky, hearty, and incredibly satisfying. I love how it brings together tender chicken, cheese-filled pasta, and that signature pesto creaminess in one cozy bowl. It’s basically everything you want on a chilly evening when you can’t decide between pasta or soup.

I first made this recipe on a rainy Sunday when I had leftover pesto in the fridge and was craving something warm and filling. The combination of fresh herbs, tender tortellini, and that nutty pesto flavor was an instant hit with my family. What I love most about this Chicken Pesto Tortellini Soup is how quickly it comes together. You get a restaurant-quality soup ready for dinner, and the leftovers taste even better the next day. The tortellini soaks up all those incredible flavors overnight. It’s perfect for meal prep or when you need a comforting dinner without spending hours in the kitchen.

What You’ll Need for This Cozy Soup

Before you start cooking, gather your ingredients and prep your veggies. I always use fresh tortellini from the refrigerated section because they cook in just 2 minutes and have the best texture. Pro tip: don’t skip the fennel if you can find it. It adds a subtle sweetness that makes this soup really special.

• 1 tablespoon olive oil
• 1 tablespoon butter
• 1 pound (450g) chicken breast, cut into 1-inch cubes
• 1 large onion, diced
• 2 medium carrots, diced
• 2-3 celery stalks, diced
• 1 small fennel bulb, diced (optional but recommended)
• 1/2 teaspoon salt
• 2 large garlic cloves, finely chopped
• 1 tablespoon fresh rosemary, finely chopped
• 1 tablespoon fresh thyme, finely chopped
• 6 cups (1.5L) low-sodium chicken stock (I recommend Better Than Bouillon or homemade)
• 1 pound (450g) cheese tortellini, uncooked (fresh from refrigerated aisle works best)
• 1/2 cup (125g) pesto (I prefer pistachio pesto for a nutty flavor)
• 1/2 cup (50g) Parmesan, freshly grated
• 6-8 fresh basil leaves
• Freshly ground black pepper to taste

How to Make Chicken Pesto Tortellini Soup

Step 1: Heat the olive oil in a large heavy-bottomed pot or Dutch oven over medium heat. Add the butter and let it melt completely. This combination gives you the best flavor base.

Step 2: Add the cubed chicken breast to the pot. Season generously with salt and freshly ground black pepper. Cook for 6-8 minutes, stirring occasionally, until the chicken reaches 165°F internal temperature and develops a golden-brown color with some caramelized edges. Remove the chicken from the pot and set aside on a plate.

Step 3: In the same pot (don’t clean it, those browned bits are pure flavor), add the diced onion, carrots, celery, and fennel. Season with 1/2 teaspoon salt. Cook for 8-10 minutes, stirring occasionally, until the vegetables are softened and the onions are translucent. The fennel should be tender with a subtle anise-like aroma.

Step 4: Stir in the finely chopped garlic, rosemary, and thyme. Cook for another minute until the herbs become fragrant and you can smell that amazing aroma throughout your kitchen. Don’t let the garlic burn or it will taste bitter.

Step 5: Pour in the chicken stock and turn up the heat to bring the soup to a boil. Once boiling, add the tortellini and the cooked chicken back to the pot. Lower the heat to a gentle simmer and cook for 2-3 minutes if using fresh refrigerated tortellini. If using frozen tortellini, cook for 5-7 minutes. For dried tortellini, follow package directions (usually 7-10 minutes). The tortellini should float to the top when done.

Step 6: Turn off the heat completely before adding the pesto. Boiling pesto can make it taste bitter and cause the basil to turn an unappealing brown color. Stir in the pesto, grated Parmesan, and fresh basil leaves. The residual heat will warm everything through and create that creamy, dreamy texture. Taste and adjust the seasoning with more salt and black pepper if needed.

Step 7: Ladle the soup into bowls and serve hot. I always sprinkle extra Parmesan and a few fresh basil leaves on top for garnish.

Perfect Pairings for Your Soup

This Chicken Pesto Tortellini Soup is incredibly hearty on its own, but a few simple sides can make it even better.

Crusty French Bread: The crispy exterior and soft interior are perfect for soaking up every last drop of that pesto broth. The texture contrast makes each bite more satisfying.

Garlic Bread: A classic pairing that adds buttery, garlicky goodness to complement the creamy soup beautifully.

Simple Arugula Salad: Peppery greens with lemon vinaigrette cut through the richness of the soup and add a fresh element.

Focaccia: This Italian flatbread is my go-to when serving Chicken Pesto Tortellini Soup because the olive oil and herbs echo the flavors in the soup.

Storing Your Leftover Soup

Store leftover Chicken Pesto Tortellini Soup in an airtight container in the refrigerator for up to 3 days. The tortellini will absorb some of the liquid as it sits, so the soup will thicken overnight. This actually makes the leftovers taste even more concentrated and flavorful.

When reheating, warm the soup gently on the stovetop over medium-low heat. Add a splash of chicken broth or water to thin it out if needed. Stir carefully to prevent the tortellini from breaking apart or turning mushy. I don’t recommend microwaving because it heats unevenly and can make the pasta rubbery.

Pro tip: if you want to freeze this soup, make it without the tortellini. The pasta doesn’t freeze well and gets mushy when thawed. Freeze the soup base for up to 3 months in a freezer-safe container, then cook fresh tortellini and add them when you reheat the soup.
