Preheat an oven to 400 degrees. Cut and break up the cauliflower into a mix of large and medium-sized florets. Coat the cauliflower florets in olive oil, salt, chili powder, paprika, and garlic powder.
Step 2
Arrange the seasoned florets on a sheet tray. Bake the tray for 30 minutes, flipping over halfway through.
Step 3
While the cauliflower is baking, make the crema by whisking together the mayo, cream, lime juice, and salt.
Step 4
Place the cooked cauliflower into a serving dish and drizzle the crema over the cauliflower. You may do this with a pastry bag, a ziploc bag with the corner cut off, or simply using a spoon or fork. Top with crumbled cotija cheese and, at your discretion, chopped cilantro.
