In a small bowl, mix together the rosemary, thyme, sage, pepper and ½ tsp. sea salt. Set aside.
Heat a large sauté pan on medium-high heat. Add olive oil.
When oil is hot, add onion, celery, carrot and ½ tsp. sea salt and sauté until soft, about 4-5 minutes. Add garlic and chopped fresh parsley. Stir and cook until fragrant, about 30 seconds. Transfer veggies to the bottom of the slow cooker.
Add small potato cubes to the slow cooker and stir.
Layer chicken thighs on top of veggies in a single layer. Sprinkle chicken thighs with previously mixed spices.
Add larger potatoes on top of the chicken and pour in the chicken broth. Give it a small stir, keeping the large potatoes on top and making sure the broth covers them. If the potatoes are not covered in the liquid, add more broth or water.
Slow cook on high for 4-5 hours or low for 7-8 hours, until chicken is cooked and potatoes are tender.
Remove large potatoes and chicken. Place on a cutting board. Let the chicken cool for a few minutes.
Add frozen peas to the slow cooker and stir.
Meanwhile, place potatoes in a blender with milk and ½ cup of the hot broth from the slow cooker. Carefully blend until smooth and add back to the slow cooker. Stir.*
Shred the chicken with two forks and stir it back into the slow cooker. Add sea salt and pepper to taste.
Separate the soup into bowls, top with additional fresh parsley (if desired) and serve. Enjoy!
*This is an optional step to make the soup feel creamier. Ifyou do not have a blender or are low on time, you can mash the larger, cookedpotatoes on a cutting board with a fork and stir in milk before adding theshredded chicken.
Notes
Chicken breasts will also work in place of the thighs.
If you want even more nutrition, you can add a leafy green, such as spinach, in at the same time as the peas until wilted.
