Prepare all your vegetables and have them ready to go before starting the recipe.
Heat a large Dutch oven on medium-high heat. Drizzle in the olive oil and rosemary. Let the rosemary sizzle in the olive oil for a minute to release its aromas. Add in the sweet potato, celery, onion, and carrot pieces. Cook for 5-10 minutes to get a nice roasted color on the vegetables.
Add in the sliced mushrooms, spinach, garlic, cinnamon, and salt. Cook until the mushroom and spinach have reduced.
Deglaze the Dutch oven by adding the chicken broth. Continue by adding the heavy cream and the cooked wild rice.
Bring to a boil, reduce the heat to low and place the lid on the Dutch oven. Simmer for 15-20 minutes. Serve and enjoy!
