Preparation Steps

• Preheat the oven to 400°F. Spray a 9x13-inch casserole dish with nonstick cooking spray. Set aside.
• In a large bowl, toss chopped cauliflower florets with olive oil, garlic powder, onion powder, salt, and pepper. Ensure all cauliflower is coated.
• Transfer cauliflower to the prepared dish, spread evenly, bake for 12 minutes, toss, then bake another 12 minutes.
• While roasting, melt butter in a pan over medium-high heat. Add flour, mix into a thick paste.
• Reduce heat to low/medium, slowly stream milk into the butter-flour mixture, whisking constantly until thickened.
• Remove from heat, stir in cheddar, Greek yogurt, cream cheese, and salt until smooth.
• Pour cheese sauce over roasted cauliflower, mix to coat thoroughly.
• Sprinkle shredded parmesan on top, broil until bubbly and golden, about 2-5 minutes.
