Select a fresh head of cauliflower, looking for a clean crown and leaves. Estimate approximately ¼ pound (approximately 115 grams) per person.
Preheat your oven to 375 degrees F (190 degrees centigrade).
Wash the fresh cauliflower head thoroughly in cold water, and pat dry with paper towels or a clean tea towel. If using frozen cauliflower for the recipe, allow it to come to room temperature, or rinse with warm water (for best results, do not defrost frozen cauliflower in the microwave)
Slice the fresh cauliflower into approximately ¼” (.6 cm) slices, or break florets apart by hand to desired size and consistency.
Place cauliflower into a large mixing bowl, and coat with olive oil.Season with salt and pepper to taste until evenly coated. Feel free also to experiment by adding rosemary or your favorite herbs.
Arrange pieces evenly on a greased cookie sheet or roasting pan, and drizzle with the leftover oil and seasonings in the mixing bowl.
Bake for 25 to 30 minutes, turning once approximately halfway through cooking, until your cauliflower florets are caramelized around the edges and tender in the center.
Allow to rest for 2-5 minutes before serving.
