Instructions
 

  • Preheat the oven to 350°F: Place the cauliflower florets into a large baking dish and drizzle with the olive oil. Season with salt, pepper, garlic powder, and parmesan cheese, then gently toss to coat the cauliflower evenly
  • Prepare the Alfredo Sauce: In a saucepan over medium heat, melt the butter and add the minced garlic. Cook for about 30 seconds until fragrant, then pour in the heavy cream and add the cream cheese. Stir continuously until the cream cheese is fully melted and the sauce is smooth. Add the parmesan cheese, salt, pepper, oregano, and crushed red pepper, then continue stirring and let the sauce gently simmer for a few minutes until slightly thickened.
  • Pour the Alfredo: Pour the Alfredo sauce evenly over the seasoned cauliflower and gently fold everything together until the cauliflower is wrapped in the rich, creamy sauce.
  • Prepare the Ground Turkey: In a separate skillet, heat the olive oil over medium heat. Add the chopped onion, minced garlic, and bell pepper, cooking until softened. Add the ground turkey and cook until browned, breaking it up as it cooks. Stir in the tomato sauce, salt, pepper, and oregano, and let the mixture simmer for a few minutes.
  • Top with Cheese: Sprinkle the mozzarella cheese evenly over the top of the dish. Bake uncovered for 30 to 35 minutes, until the cheese is melted, bubbly, and lightly golden. Remove from the oven and let the dish rest for a few minutes before serving. Enjoy.
