Step 1

In a Dutch oven, heat the oil over medium heat. Add the onion, carrot, and celery. Cook, stirring occasionally, until softened, 10 to 12 minutes, adding the garlic during the last minute.

Step 2

Add the flour and cook, stirring constantly, until evenly combined and vegetables are well coated, about 1 minute. Gradually stir in the chicken broth. Add the chicken, thyme, salt, and pepper, and bring the mixture to a simmer over medium. Reduce the heat to medium-low and simmer until the chicken is cooked through, about 5 minutes.

Step 3

Stir in the gnocchi and cook, covered, stirring occasionally, under tender and fluffy, 4 to 5 minutes. Stir in the spinach and half and half. Cook, stirring occasionally, until well combined and spinach is tender, 1 to 2 minutes. Remove from heat. Season to taste with salt and pepper.
