A few people have asked me for the recipe I use to make this. It takes forever but is so worth it.
1 1/3 cups wild rice
4 chicken breasts, cut into pieces
7 cups chicken broth (low sodium)
1 cup chopped celery
1 cup chopped onion
2 tablespoons vegetable oil
1 cup fresh mushrooms, sliced
2 tablespoons chicken bouillon granules
3/4 teaspoon ground white pepper
1/2 cup butter
3/4 cup all-purpose flour
4 cups milk
3/4 cup white wine
Cook the wild rice according to package directions, but remove from heat about 15 minutes before it's done. Drain the excess liquid, and set aside.
In a stock pot over high heat, combine the chicken and the broth. Bring to a boil, and then reduce heat to low. Simmer until chicken is cooked and tender. Remove chicken from the pot, and allow it to cool. Strain the broth from the pot, and reserve for later.
In the same stock pot over medium heat, saute the celery and onion in the oil for 5 minutes. Add the mushrooms, and cover. Cook for 5 to 10 minutes, stirring occasionally, until everything is tender. Return the broth to the stock pot, and add the partially cooked wild rice. Stir in the bouillon, white pepper; simmer, uncovered, for 15 minutes.
Meanwhile, melt butter in a medium saucepan over medium heat. Stir in the flour until smooth. Whisk in the milk, and continue cooking until mixture is bubbly and thick. Add some of the broth mixture to the milk mixture, continuing to stir, then stir all of the milk mixture into the broth mixture.
Mix in the reserved chicken meat and the white wine. Allow this to heat through for about 15 minutes.
