In a heavy bottom pot, melt the butter over medium-high heat. Add the carrots, celery, onion, and garlic to the pan. Season with salt and pepper. Cook for 6 to 7 minutes until the onions are translucent and the carrots are starting to soften.
3 tablespoons salted butter, 2 medium carrots, 2 ribs celery, 1 medium yellow onion, 2 cloves garlic
Add the flour and stir until the vegetables are well coated. Cook for about 1 minutes then slowly add the wine while stirring to combine the flour and wine into a thick liquid.
3 tablespoons all purpose flour, ¼ cup white wine
Slowly pour in the chicken stock, stirring to combine. Thoroughly rinse the rice before using. Add the thyme and rice to the pan and increase the heat to high. Bring the liquid to a simmer, stirring occasionally to keep the rice from sticking to the bottom of the pan.
½ teaspoon dried thyme or 3 sprigs fresh thyme, 4 cups chicken stock, ½ cup white rice
Once the broth is almost at a boil, reduce the heat to medium, partially cover the pan, and cook for 5 minutes, stirring occasionally. After the first 5 minutes of cooking, add the chicken and mushrooms to the pan, partially cover and cook for 10 to 12 more minutes until the rice is very tender.
8 ounces sliced mushrooms, 1 pound cooked chicken
Reduce the heat to low, stir in the heavy cream and season liberally with salt and pepper to taste. I typically use about ¾ teaspoon salt and ½ teaspoon pepper.
1 cup heavy cream, salt and pepper
