Ingredients

  • 5 medium carrots, peeled and chopped
  • 5 celery stalks, chopped
  • 1 small onion, diced
  • 4 garlic cloves, minced
  • 1 cup (6 oz/ 170 g) wild rice, uncooked
  • 8 oz fresh mushrooms, sliced (baby bellas, cremini, or white button)
  • 4 cups (32 oz/ 907 g) vegetable, chicken, or beef stock
  • 1 tsp salt
  • 1 tsp poultry seasoning
  • ½ tsp Herbes De Provence
  • 6 Tbsp unsalted butter
  • ½ cup all-purpose flour
  • cups milk, whole or 2%
  • Kosher salt and freshly ground black pepper

Instructions

Instant Pot Method

  • Add the first 10 ingredients in the Instant Pot and cook for 45 minutes (Press Manual, High Pressure). When the time finishes, release the steam valve on the lid.
  • When the soup has finished and is releasing steam, melt the butter in a medium saucepan. Whisk in the flour and cook, stirring constantly for 1 minute. Whisk in the milk, until it is smooth and thick. Add 1 tsp salt.
  • Stir the thickened sauce into the soup that is in the Instant Pot until incorporated. Season with salt and freshly ground black pepper to taste.

Slow Cooker Method

  • Cook first 10 ingredients in a slow cooker on LOW for 7-8 hours or on HIGH for 4-5 hours. Then on the stovetop, melt the butter in a medium saucepan. Whisk in the flour and cook, stirring constantly for 1 minute. Whisk in the milk, until it is smooth and thick. Add 1 tsp salt.
  • Stir the thickened sauce into the soup that is in the slow cooker until incorporated. Season with salt and freshly ground black pepper to taste. *For the best results: Add the wild rice the last 2 hours of cooking on LOW or 1 1/2 hour on HIGH. If the wild rice is added the entire cooking time, it is okay but some of the rice will split open.

Notes

  • If you want a thinner soup, add 1 more cup warmed stock. 
  • Only use plain Wild Rice for this recipe. It won't work with white, brown, or mixed rice. 
  • Poultry Seasoning contains: ground thyme,sage,marjoram, rosemary, black pepper, and nutmeg. (Can substitute 1 tsp total with any of these).
  • Herbes De Provence contains: dried thyme, basil, rosemary, tarragon, marjoram, thyme, savory, oregano, and crushed bay leaf. (Can substitute 1/2 tsp total with any of these).
  • You can add cooked chicken, ham, or chicken sausage.
