Chicken Pesto Tortellini Soup is the kind of bowl that makes a cold evening feel instantly better. It is hearty, creamy, and packed with flavor from tender chicken, pillowy cheese tortellini, and a generous spoonful of pesto stirred right in. I started making this on weekends when I wanted something that felt special without spending hours in the kitchen.
The first time I added pesto to a tortellini soup, I knew I had stumbled onto something worth repeating. That nutty, herby richness turns a simple broth-based soup into something that tastes like it has been simmering all day. The fresh fennel in the vegetable base is a small touch that makes a big difference. Every spoonful delivers warmth, comfort, and serious flavor.

Ingredients for Chicken Pesto Tortellini Soup
I have tested this soup many times, and the quality of your pesto and stock really matters here. I always use low-sodium chicken stock so the salt level stays easy to control, since the pesto, tortellini, and Parmesan all bring their own saltiness to the pot.
- 1 tbsp olive oil
- 1 tbsp butter — I recommend using unsalted butter so you can better control the seasoning
- 1 lb chicken breast (cut into 1-inch cubes)
- 1 large onion (diced)
- 2 medium carrots (diced)
- 2 to 3 celery stalks (diced)
- 1 small fennel bulb (diced) — Pro tip: do not skip the fennel; it gives the broth a subtly sweet depth that is hard to replicate
- 1/2 tsp salt
- 2 large garlic cloves (finely chopped)
- 1 tbsp fresh rosemary (finely chopped)
- 1 tbsp fresh thyme (finely chopped)
- 6 cups low-sodium chicken stock — My go-to is a good quality store-bought brand; it is the backbone of this soup
- 1 lb cheese tortellini, uncooked (fresh refrigerated preferred) — In my experience, fresh tortellini from the refrigerated aisle cooks in just 2 to 3 minutes and holds up beautifully
- 1/2 cup pesto (store-bought or homemade)
- 1/2 cup Parmesan, freshly grated — I always grate my own for better flavor and melt
- 6 to 8 fresh basil leaves
- Freshly ground black pepper, to taste
Step-by-Step Instructions
In my experience, browning the chicken first is the step that makes the biggest difference in flavor for this Chicken Pesto Tortellini Soup. Do not rush it; that golden color on the chicken adds richness to the whole pot.
Step 1: Heat the olive oil over medium heat in a large heavy-bottomed pot. Add the butter and let it melt completely.
Step 2: Add the chicken breast cubes, season with a pinch of salt and black pepper, and cook for 6 to 8 minutes until golden brown on the outside. Remove the chicken from the pot and set it aside on a plate.
Step 3: In the same pot, add the diced onion, carrots, celery, and fennel. Season with 1/2 teaspoon salt. Cook for 8 to 10 minutes, stirring occasionally, until the vegetables are softened and lightly golden. Do not rush this step; a well-softened veggie base builds a richer broth.
Step 4: Stir in the garlic, fresh rosemary, and fresh thyme. Cook for another minute until the herbs smell fragrant and the garlic softens slightly.
Step 5: Pour in the chicken stock and turn up the heat to bring it to a full boil. Add the tortellini and the cooked chicken back to the pot. Lower the heat and simmer for 2 to 3 minutes, just until the tortellini is tender.
Step 6: Turn off the heat. Stir in the pesto, Parmesan, and fresh basil leaves. Taste and adjust the seasoning with salt and black pepper as needed.
Step 7: Serve hot with extra grated Parmesan and fresh basil on top. A slice of crusty bread on the side is highly recommended.
What to Serve with Chicken Pesto Tortellini Soup
This soup is filling on its own, but the right side dish can round out the meal perfectly. Here are some great pairings:
Crusty Garlic Bread: A thick slice of garlic bread is the classic companion to any hearty soup. It soaks up the pesto broth beautifully and adds a satisfying crunch to contrast the soft tortellini.
Baked Caesar Chicken with Creamy Parmesan Sauce: If you are feeding a group and want to stretch the meal, this creamy Parmesan chicken on the side adds a rich, protein-packed complement to the soup’s bright pesto flavors.
Chicken Sausage and Broccoli Orzo: For a heartier spread, serve this orzo alongside the soup. The broccoli and sausage add texture variety and keep the Italian-inspired theme going strong.
Italian Chicken Saltimbocca: This elegant Italian chicken dish pairs naturally with a pesto-based soup. The sage and prosciutto flavors complement the herby broth without competing with it.
Juicy High Protein Chicken Orzo: A simple green salad with a lemon vinaigrette cuts through the richness of the pesto and Parmesan, balancing the meal and adding a fresh, crisp contrast.
Marry Me Chicken Soup: If you love cozy chicken soups as much as this one, this creamy crowd-pleaser is a must-try next. It is just as comforting and delivers a different but equally satisfying flavor profile.
Ginger Scallion Chicken Noodle Soup: Another warming soup option worth bookmarking. The ginger and scallion bring a completely different flavor direction that is perfect for rotating through your winter soup rotation.
Leftovers and Storage Tips
This Chicken Pesto Tortellini Soup stores well and tastes just as good the next day. Keep leftovers in an airtight container in the refrigerator for up to 3 to 4 days. Keep in mind that the tortellini will continue to absorb liquid as it sits, so the soup will thicken overnight.
When reheating, warm it gently on the stove over medium-low heat and add a splash of chicken broth to loosen it back up. Stir carefully so the tortellini stays intact and does not turn mushy. I recommend reheating only the portion you plan to eat rather than the whole pot at once.
Pro tip: if you want to freeze this soup, do it before adding the tortellini. Freeze the broth and chicken base for up to 3 months, then cook fresh tortellini and stir it in right before serving. This keeps the texture perfect every time.
Frequently Asked Questions
Can I use frozen or dried tortellini instead of fresh?
Yes. Frozen tortellini works great; just add 2 to 3 extra minutes of simmering time. Dried tortellini will need even longer based on the package directions. Fresh tortellini is still the easiest and fastest option.
Can I make this soup without fennel?
You can skip the fennel if needed, but it does add a subtly sweet, aromatic depth to the broth that is hard to replace. If you want a similar effect, a pinch of anise seed or a small amount of diced leek can work as a mild substitute.
What type of pesto works best in this recipe?
Classic basil pesto is the most common choice and works beautifully here. You can also use pistachio pesto for a nuttier, richer flavor. Store-bought pesto is perfectly fine, but if you have homemade on hand, it will take this soup to another level.

Chicken Pesto Tortellini Soup is one of those recipes you will keep coming back to all season long.
