Instructions

Preheat your oven to 425 degrees F. Line a large baking sheet with parchment paper or lightly grease it with olive oil.
Remove the leaves from the cauliflower and trim the stem end so that the cauliflower can sit flat.
Cut the cauliflower into 3/4 to 1-inch thick 'steaks'. You should get about 3 to 4 steaks depending on the size of your cauliflower. Reserve any loose florets for roasting alongside or another use.
In a small bowl, combine the olive oil, minced garlic, chopped rosemary, thyme leaves, sea salt, black pepper, and lemon juice. Stir well to combine.
Brush both sides of each cauliflower steak generously with the garlic and herb oil mixture and place on the prepared baking sheet. If you have reserved florets, toss them in the remaining oil and spread them around the steaks.
Roast in the preheated oven for 20 to 25 minutes, turning once halfway through, until the cauliflower steaks are golden and tender but still hold their shape.
Remove from oven and garnish with freshly chopped parsley before serving. Serve warm as a flavorful holiday side dish.
Optional: Serve with a wedge of lemon for extra brightness.
