Add chicken, chicken broth, minced garlic, bay leaves, rosemary, and thyme to your pressure cooker. Cover with the lid, seal, and set to pressure cook on high for 20 minutes.
Once the time has gone off, release the pressure with a quick release. Then remove the lid. Shred or cube the chicken. Add it back into the mix with the carrots, celery, and onions. Replace the lid and set it to pressure high for 3 minutes.
Again, quick release the pressure on the lid and remove the lid. Switch setting to saute. Then add in the spinach and gnocchi. Cook for 3-5 minutes, depending on cooking recommendations on the gnocchi.
The last step, check for seasoning. Add in salt and pepper as needed. I do this as one of the last things because depending on how salty your broth is, you might not need any salt.
Pour in the evaporated milk and turn off the heat. Mix to incorporate the milk. That is it!
You are done. Now, sit back and enjoy. You deserve it.
