Preheat the oven to 400℉
Trim the leaves off the cauliflower and wash the whole head. Keep the stem intact, trim it if you need to to allow the cauliflower to sit evenly.
1 whole cauliflower
Turn the cauliflower upside down, or core side up, and brush it with some olive oil then sprinkle with salt and pepper.
¼ tsp coarsely ground pepper, Olive oil, ½ tsp Coarsely ground salt
Turn it around and repeat the process. Brush the whole head with olive oil and sprinkle with the remaining salt and pepper.
½ tsp Coarsely ground salt, Olive oil, ¼ tsp coarsely ground pepper
Place it on a parchment paper lined cookie sheet and bake in the preheated oven for 45-60 minutes. At 45 minutes you will still get some crunch and by 60 minutes the whole head should be soft inside and out so cook to your preference.
In the last 10 minutes of baking, add the butter to a small pan and melt on medium heat. Once it starts to sizzle add the breadcrumbs and toss until well combined. Toast the breadcrumbs for 5 minutes or until golden brown tossing occasionally to prevent burning.
2 tbsp butter, ¼ Breadcrumbs
