Sauté Onion: Add the oil to a large pot or Dutch oven over medium heat along with the diced onion. Saute for 2-3 minutes, or until they start to become tender. Add the minced garlic and continue sautéing for an additional 30 seconds, or until fragrant.
1 Tbsp. oil, 1 onion, 3 cloves garlic
Add Chicken and Veggies: Pour in the broth, scraping the bottom of the pot to release any bits or pieces that might be stuck. Add the celery, carrots, potatoes, squash, herbs, paprika, salt, and pepper to the pot. Stir until everything is well combined. Immerse the chicken in the liquid.
5 cups chicken broth, 4 stalks celery, ¾ lb. carrots, 1 lb. red potatoes, 2 squash, 1 ½ tsp. dried herbs, ¼ tsp. paprika, 1-1 ½ tsp. salt, ¼ tsp. black pepper, 1 lb. chicken breasts
Boil & Simmer: Turn the heat to high and bring everything to a boil. Once boiling, reduce the heat to low, cover the pot with a lid, and cook for 15-20 minutes, or until the chicken is cooked through and the vegetables are tender.
Make Slurry and Shred Chicken: While the soup is cooking, whisk together the warmed milk and the cornstarch in a medium-sized bowl until smooth. Pour into the soup, once cooked, and stir to combine. Shred the chicken using two forks to break it apart into smaller pieces.
½ cup milk, 3 Tbsp. cornstarch
Serve soup with a sprinkle of chopped fresh herbs, if desired, and enjoy!
