Preheat oven to 350F.
Place butter in a large, oven safe baking dish and transfer to oven. Once butter has melted, remove baking dish.
Top butter with veggie broth, rice, onion, garlic, pardon peppers and seasonings. Whisk to combine. Add chicken, cover with aluminum foil and return to oven for 45 minutes.
Remove baking dish from oven, remove aluminum foil and stir rice. Add parmesan cheese, heavy cream and grape tomatoes. Stir continuously for a few minutes until rice becomes creamy, adding more heavy cream as necessary. Fold in cilantro, sprinkle with fresh cracked black pepper and serve.
