Heat a large pot or Dutch oven over medium heat with 1 tablespoon of oil.
Once the oil shimmers, add in the celery, onion, garlic, and shredded carrot. Saute for 2-3 minutes until the vegetables are soft and the onions are semi-translucent.
Pour in the chicken broth and use the bottom of a wooden spoon to scrape up any browned bits from the bottom.
Add in the cooked chicken, thyme, Italian seasoning, and salt and pepper. Stir well.
Increase the heat to medium-high and bring to a boil.
Once a boil is reached, add in the gnocchi and stir gently.
Boil for 4 minutes, then reduce the heat to low-medium and cook for an additional 4 minutes.
Pour in the milk and heavy cream and stir well to incorporate it into the soup.
Increase to medium heat and simmer for 3-4 minutes, or until the soup begins to thicken slightly.
Add in the chopped spinach and cook for an additional 1-2 minutes, or until the spinach is wilted and dark green.
Taste and adjust salt, pepper, and other seasonings to your preference.
Serve and enjoy! Garnish as desired (fresh herbs, cracked pepper, parmesan, etc).
Notes
Storage: Transfer leftovers to an airtight container. Keep refrigerated for 3-4 days. Reheat portions as needed. Gluten free: Use gluten free gnocchi and verify your chicken broth is free from gluten-containing ingredients (barley is the most common in broth). Without heavy cream: Substitute the heavy cream and milk for 2 cups of evaporated milk or half-and-half.
