Add chicken and broth: Stir in the chicken breasts, chicken broth, dried thyme, garlic powder, salt, and pepper. If using an Instant Pot, close the lid and set to high pressure for 15 minutes; for the stovetop, bring to a boil, then reduce the heat and simmer for 30 minutes.
Shred the chicken: Once cooked, remove the chicken from the pot. Shred it using two forks and return it to the pot.
Incorporate peas and cream: Stir in the frozen peas and heavy cream, allowing the soup to heat through and the flavors to meld, about 5 minutes.
Top and serve: If desired, top the soup with biscuits or pie crust before serving, either baked separately or placed on top and baked until golden brown.
