Prepare your ingredients – Peel and dice the potatoes, chop the onion, and mince the garlic.
Layer into the slow cooker – Add chicken breasts to the bottom of your slow cooker. Top with corn, potatoes, onion, garlic, thyme, paprika, and a pinch of salt and pepper.
Add broth – Pour in the chicken broth, making sure the ingredients are fully submerged.
Cook – Cover and cook on low for 6–7 hours or on high for 3–4 hours, until the chicken is cooked through and the potatoes are tender.
Shred chicken – Remove the chicken breasts, shred with two forks, and return to the slow cooker.
Thicken the chowder – In a small bowl, whisk together flour with milk until smooth. Stir this mixture and the cream into the slow cooker.
Final simmer – Turn the slow cooker to high and cook for another 20–30 minutes, or until the chowder thickens.
Serve and garnish – Ladle into bowls and top with crumbled bacon, chopped green onions, or fresh herbs if desired.
