Next, in a small bowl whisk together a 1/2 cup of olive oil, 3 tbsp of white balsamic vinegar, 1 1/2 tsp smoked paprika, 1 tsp salt, and 1/2 tsp pepper, 1/4 tsp garlic powder, and 1/8 tsp cayenne pepper. Once everything is thoroughly mixed together, turn the cauliflower head upside down and pour about half of the mixture evenly into it. Then, flip it right side up and pour the rest all over the top. Place the cauliflower in the oven and bake it at 400° for 55 minutes, or until it's as soft as you'd like it!
