Saute Vegetables: Add butter to a large pot or Dutch oven over medium heat and wait for it to melt. Once melted add the diced onion, carrots, and celery. Saute veggies for 3-4 min, add garlic, and continue sauteing for an additional 30 seconds, or until fragrant.
2 Tbsp. butter, 1 small sweet onion, 1 cup carrots, 3 celery ribs, 4 cloves garlic
Season the Broth: Pour in the chicken broth and mix in the honey, rosemary, thyme, paprika, red pepper flakes, salt, and black pepper.
6 cups chicken broth, 2 tsp. honey, ½ tsp. each of dried rosemary, ¼ tsp. red pepper flakes, 1 tsp. salt, ¼ tsp. black pepper
Add Chicken and Simmer: Cut the chicken breasts into 4-ounce portions if they aren’t already. Add the chicken to the pot, making sure they are all completely immersed in the liquid. Turn the heat to high and bring the soup to a boil. Once boiling, reduce the heat to medium-low, cover the pot with a lid, and simmer for 15-20 minutes, or until the chicken is cooked through.
1 lb. chicken breasts
Cook Pasta: Cook the orzo pasta according to the package directions and then drain in a colander.
1 cup Orzo pasta
Shred Chicken: Remove the cooked chicken from the pot and shred it on a cutting board using two forks.
Mix in Slurry, Chicken, Pasta, Lemon, and Spinach: Whisk together the warmed milk and cornstarch in a medium-sized bowl until smooth. Add this to the pot along with the shredded chicken, cooked orzo pasta, lemon juice, zest, and spinach. Increase the heat to medium and cook for an additional 2-3 minutes, or until the spinach is wilted.
¼ cup lemon juice, 2 tsp. lemon zest, 4 cups baby spinach, 1 cup milk, 3 Tbsp. cornstarch
Serve soup with additional finely chopped fresh parsley, if desired.
