Boil your gnocchi first in salted water according to the package. This usually takes 2-3 minutes until they float and are soft. Drain and set aside.
Heat olive oil in your pressure cooker on sauté mode. Season the chicken thighs with salt, garlic powder, and smoked paprika.
Cook chicken thighs for 6-8 minutes on each side until browned and cooked through. Remove and set aside.
Add butter to the cooker then onion. Sauté 3-4 minutes until soft and fragrant.
Stir in grape tomatoes and garlic; cook 2-3 minutes until softened and aromatic.
Return chicken with ½ cup broth. Lock lid, high pressure 5 minutes, then quick release.
Add gnocchi, spinach, remaining broth, cream, and stir in flour. Cook with sauté mode for 4-5 minutes until thickened, then stir in parmesan and serve hot.
You can store leftovers in the fridge for 3-4 days. Reheat gently on stove with extra broth to keep creamy texture. For freezing, omit spinach and add fresh when reheating.
