Add 8 cups of chicken broth to a medium sauce pan and simmer on low heat
Add 2 tablespoons of olive oil to a medium pan with elevated edges on medium heat. Once heated, add the shallots and cook until translucent. Add the garlic and stir until fragrant.
Add one tablespoon of butter, let melt for about 30 seconds and add in the mushrooms, salt, pepper, poultry seasoning, herbs de Provence, and dried oregano. Stir until mushrooms are fully cooked. Once cooked, place mushrooms on a plate and set aside.
In the same pan (don’t wash away the flavor from the mushrooms!), add in the remaining 2 tablespoons of olive oil and the arborio rice and allow to toast for about 1 minute
Add white wine to deglaze the pan(scraping the brown flavor bits to create a sauce) and allow the liquid to absorb into arborio rice while continuously stirring
Add warm broth one cup at a time into risotto, waiting until previous cup of liquid has absorbed, but risotto is still creamy. At cup 4, add the sprig of rosemary whole into the risotto being careful not to remove any leaves.
After adding the last cup of broth, fish out the rosemary sprig, add in the last tablespoon of butter, cooked mushrooms, truffle oil and grated Parmesan and stir until well combined
Turn off heat once risotto has absorbed liquid and is still creamy. Top with more grated Parmesan and fresh parsley and serve!
