Preheat the oven to 350 F.
Mix the olive oil, herbs, spices, salt, pepper, lime juice, minced garlic, and chimichurri in a small bowl until well combined.
Place the cauliflower on a baking sheet covered with parchment paper, and spread the oil mixture evenly on top using a silicone brush.
Bake, uncovered, for 1 hour to 1 hour 20 minutes, depending on the size of the cauliflower, until a large wooden skewer can be inserted easily.
