Preheat the oven to 425 degrees. Coat a baking sheet with olive oil cooking spray.
Trim any tough ends of the broccoli crowns, leaving roughly 2 inches of the stalk attached. Slice the broccoli into ½-inch-thick steaks. Side Note: Reserve any fallen & excess florets for another use, such as broccoli cheese soup.
Drizzle the oil on both sides of the broccoli steaks. Season both sides with sea salt, freshly cracked black pepper, crushed red pepper flakes, and garlic powder to taste, and place in a single layer on the prepared baking sheet.
Roast for 10 minutes.
Carefully flip the steaks over and roast for another 10-13 minutes, or until fork-tender and lightly charred.
Remove from the oven and top each steak with fresh lemon juice. Top with pecorino chees and almonds.
