Dice onion and garlic and add to large pot with coconut oil and sea salt. Bring to medium heat and cook stirring often, until onion turns translucent (approx. 10 mins).
Pour in arborio rice and toast until grains become lightly perfumed (2-3 mins). Then pour in vegetable broth, starting with 2 cups, and adding more in splashes as it thickens, (I used 5 cups total). Cook for 20-30 minutes, stirring often until risotto is desired texture, (soft and pleasantly chewy). Add nutritional yeast and stir to combine.
While risotto is cooking, cook your balsamic mushrooms. Slice mushrooms and add to a skillet with coconut oil and sea salt. Bring to medium heat. Cook mushrooms (approx. 10 mins). Then reduce heat to low and add balsamic vinegar, cook for another 2-3 minutes.
Add balsamic mushrooms to cooked risotto. Sprinkle with chopped parsley and stir to combine. Serve risotto in bowls.
