In a big Dutch oven, melt the butter on low heat. Once it’s melted, toss in the carrots, celery, and onion. Sprinkle with a little salt and a few cracks of pepper, cooking over medium heat until the veggies soften, about 5 minutes.
Add in the garlic, wild rice, and flour. Stir everything together and let it cook for 1-2 minutes to lightly toast the rice and cook the flour.
Gradually pour in the chicken stock while stirring continuously. Toss in the herbs and bring the mix to a simmer. Cover and let it simmer for 40-45 minutes until the rice is almost cooked through.
Stir in the shredded chicken and heavy cream; continue cooking until everything is warmed through and the rice is tender, about another 5-10 minutes.
Taste and season with salt and pepper before serving. Enjoy this comforting dish with loved ones!
