  • Cook risotto rice with 3 cups vegetable broth. I cook mine in the instapot on the rice setting.
  • In a large pot warm 2 tbsp olive oil and sauté onion and garlic until onions are translucent.
  • Add all the cauliflower, zucchini, tomato, salt, pepper and thyme and chili flakes if using. Cook until vegetables are tender about 10 minutes.
  • Next add the cooked risotto rice and mix into the veggies. Continue cooking everything together with 2 cups more vegetable broth for about 2-3 minutes.   Add the remainder 1 cup broth if needed to make a creamy risotto.
  • To keep it vegan skip the cheese and serve right away.
  • Next add the Parmesan cheese and mix into the rice.  Risotto is ready! Serve with garnish of extra Parmesan cheese.
