- Yellow onion carrots celery and fennel: Build a classic aromatic flavor base Pick crisp vegetables and firm fennel bulb for the freshest taste
- Garlic fresh rosemary and thyme: Add fragrance and savory depth Fresh herbs make a noticeable difference here

Step-by-Step Instructions
- Warm the Base:
- Start by heating the olive oil in a large heavy-bottomed pot over medium heat Once shimmering add the butter and let it melt fully swirling gently to prevent browning This combination adds both flavor and silky texture to the soup’s base
- Brown the Chicken:
- Add the cubed chicken to the hot oil and butter Season immediately with a sprinkle of salt and black pepper Let the chicken pieces sear on each side for six to eight minutes until they turn golden Conservatively move them so you get even browning Remove the chicken from the pot with a slotted spoon once cooked and set aside on a plate This step seals in juiciness and layers the bottom of the pot with flavorful bits
- Soften the Vegetables:
- Without cleaning the pot add the diced onion carrots celery and fennel along with half a teaspoon of salt Stir everything together and cook over medium heat for eight to ten minutes stirring occasionally until the vegetables soften and start to turn translucent This stage gently draws out natural sweetness intensifying the base flavors Do not rush this step as patiently softened vegetables will help your soup taste extra rich
- Build Aroma:
- Sprinkle in the chopped garlic rosemary and thyme once vegetables are soft Stir and cook for one minute until fragrant as this helps activate their oils and aroma
- Add Stock and Return Chicken:
- Stir in the chicken stock to deglaze any flavorful bits stuck to the bottom of the pot Pour in all six cups then turn up the heat to bring the mixture gently to a boil Add the browned chicken back into the pot
- Cook the Tortellini:
- When the soup starts to boil add the uncooked cheese tortellini Stir gently and reduce the heat to a gentle simmer Let the tortellini cook two to three minutes or until just tender and floating This timing keeps the pasta plump not mushy
- Finish with Pesto and Cheese:
- Turn off the heat and immediately add the pesto freshly grated Parmesan and torn basil leaves Stir everything together so the cheese melts into the hot broth and pesto blends throughout Taste and adjust salt pepper or additional pesto as needed
- Serve and Garnish:
- Ladle the soup into bowls Serve hot and top each serving with extra grated Parmesan and a few more torn basil leaves for freshness

My favorite part is watching the pesto swirl into the broth The scent of basil and Parmesan always reminds me of making this soup with my kids swirling their own spoonfuls in before digging in
Storage Tips
If you plan for leftovers separate cooked tortellini from the soup base Store in airtight containers in the fridge for up to two days Reheat gently over medium low heat and add a splash of extra stock if it thickens The tortellini can over soften when stored together so combine fresh before serving if storing ahead
Ingredient Substitutions
You can use rotisserie chicken shredded and added at the end to save time For a vegetarian twist swap the chicken for canned cannellini beans or baby spinach You could experiment with different filled tortellini such as spinach or mushroom for a new flavor profile Choose nut free pesto if allergies are a concern
