In a large pot or Dutch oven, heat the olive oil over medium heat. Add the diced onion and sauté for about 3-4 minutes until softened.
Stir in the minced garlic, red bell pepper, carrots, and celery. Cook for an additional 5 minutes until the vegetables are tender.
Pour in the chicken broth and add the shredded chicken, frozen corn, diced potatoes, thyme, paprika, salt, and pepper. Bring to a boil, then reduce heat and let simmer for 20-25 minutes until the potatoes are tender.
Stir in the heavy cream and let the chowder simmer for another 5 minutes. Adjust seasoning if necessary.
Serve hot, garnished with fresh parsley.
