Step 1

Prep. Preheat your oven to 425°F and line a baking sheet with parchment paper.

Step 2

Slice the cauliflower. Remove the leaves from the cauliflower heads and trim the stem end to create a flat base for the cauliflower to stand on. Slice each cauliflower head vertically into 1-inch thick slices, creating "cauliflower steaks." Don’t worry if the ends fall apart a bit. You can still roast those.

Step 3

Season the cauliflower. Whisk together the olive oil, lemon juice, salt, pepper, garlic powder, and half of the parsley. Brush both sides of each cauliflower steak with the olive oil mixture.

Step 4

Roast. Arrange the seasoned cauliflower steaks in a single layer on the prepared baking sheet. Roast for 25 to 30 minutes or until the cauliflower is tender and golden brown, flipping them halfway through cooking.

Step 5

Serve. Serve them warm, drizzled with olive oil, and garnished with the remaining parsley.
