Ingredients

• For the Broth Base
• 1 chicken carcass (from a rotisserie chicken is great!)
• 1 medium onion, minced
• 2 medium carrots, minced
• 3 celery stalks, minced
• 1 medium tomato, minced
• 1 cup / 240ml tomato passata
• 1 cup / 240ml chicken broth
• 1 tbsp Italian herbs
• Water to cover
• For the Soup
• 2 cups diced chicken breast, about 1 lb / 450g
• 2 medium zucchini, spiralized into zoodles
• 2 medium carrots, chopped
• 3 celery stalks, chopped
• Salt to taste

Instructions

1. Create the Broth Base: Place the chicken carcass, minced onion, minced carrots, minced celery, minced tomato, tomato passata, 1 cup of chicken broth, and Italian herbs into your Instant Pot. Add enough water to cover the .
2. Pressure Cook Part One: Secure the lid, set the steam valve to ‘Sealing’, and cook on the ‘Stew/Soup’ setting for 30 minutes.
3. Strain the Broth: Allow the pressure to release naturally. Carefully open the lid and strain the contents through a fine-mesh sieve into a large bowl or back into the now-empty Instant Pot liner. Use the back of a spoon to press the cooked vegetables against the sieve to extract all their flavorful juices. Discard the solids.
4. Add Soup : Return the rich, strained broth to the Instant Pot. Stir in the diced chicken breast, chopped carrots, and chopped celery.
5. Pressure Cook Part Two: Secure the lid again, ensure the valve is set to ‘Sealing’, and cook on the ‘Stew/Soup’ setting for 10 minutes.
6. Finish the Soup: Allow the pressure to release naturally once more. Carefully open the lid and season the soup with salt to your liking.
7. Cook the Zoodles: Stir in the spiralized zucchini. Place the lid back on the Instant Pot (no need to seal) and let it sit for 5 minutes. The residual heat will perfectly cook the zoodles until they are tender-crisp.
8. Serve: Ladle the hot soup into bowls and enjoy immediately.

Pro Tips

• For an even richer broth, add a bay leaf and a few whole peppercorns to the first pressure cooking cycle.
• To prevent soggy zoodles in leftovers, store the soup and the spiralized zucchini separately. Add the zoodles to individual portions when reheating.
• Don’t skip pressing the cooked vegetables through the sieve! This step is crucial for creating a silky, intensely flavorful broth base.
• Feel free to add other herbs like fresh parsley or thyme at the end for a burst of fresh flavor.

Q: How do I keep my zoodles from getting mushy

Q: How long does this Instant Pot soup take to make
A: This entire soup comes together in under an hour. It involves a 30-minute pressure cook for the broth and a 10-minute pressure cook for the soup, plus the time for the pot to build and release pressure.
