  • Wash and pat dry the cauliflower head then cut the florets and discard stems.
  • Slice onions lengthwise and set aside.
  • Smash garlic cloves and set aside.
  • In a bowl, add the Parmegiano-Reggiano & Pecorino Romano grated cheeses, eggs, and Tuscan Sunset seasoning. Beat well then set aside.
  • In a very large skillet, add 2 Tablespoons of EVOO until hot (medium heat). Add the onions and caramelize to a golden brown.
  • Once caramelized, add a bit more EVOO then add the raw cauliflower florets with the smashed garlic. Season with pink Himalayan salt & black pepper to taste. Cover and cook for about 8-10 minutes until cauliflower is cooked but not mushy. Remove from heat.
  • Heat the larger bottom part of the frittata pan then add 1 Tablespoon of EVOO plus a little to coat the top frittata pan. When hot enough add the cauliflower & onions to cover the bottom of the pan.
  • On a medium-low flame, add the egg mixture. Place the oiled frittata cover on top and cook for about 5 minutes. Flip the pan over and continue to cook for another 5 minutes. Remove the larger pan that's on top then slide the frittata from the upper pan into a 9" pie plate or serving dish. Garnish with some grated cheese and a sprig of fresh parsley if desired.
  • Cauliflower Frittatas can be frozen and then thawed before heating up in a microwave or oven.
