1Preheat oven to 425 degrees F (220 degrees C). Lightly grease a baking sheet.
2Place potatoes on prepared baking sheet. Bake potatoes in the preheated oven until tender, about 30 minutes.
3Heat olive oil in a large soup pot over medium heat. Stir celery, carrots, onion, and garlic into the hot olive oil; season with salt and pepper. Cook and stir until vegetables soften, about 10 minutes.
4Stir chicken broth and milk into vegetable mixture; bring to a boil. Add cauliflower to vegetables and chicken broth mixture. Reduce heat to medium and cook until cauliflower is tender, about 10 minutes.
5Stir potatoes, chicken, and Parmesan cheese into vegetables and broth; simmer until chicken is heated and cheese is melted, 20 minutes.
Footnotes
Cook's Note:
A food processor is a great way to cut down on prep time. I use it to chop all the veggies and shred the chicken breast.
Tip
Aluminum foil helps keep food moist, ensures it cooks evenly, keeps leftovers fresh, and makes clean-up easy.
