Remove the leaves and stem from the cauliflower, then slice it into 1-inch thick steaks. You should be able to get about 2-4 steaks, depending on the size of the cauliflower.
In a small bowl, combine the olive oil, minced garlic, thyme, oregano, smoked paprika, salt, and pepper to create a flavorful herb mixture.
Place the cauliflower steaks on a parchment-lined baking tray. Brush the herb mixture generously on both sides of the steaks.
Roast the cauliflower in the preheated oven for 25-30 minutes, flipping halfway through, until the edges are golden brown and the cauliflower is tender.
Once done, remove the cauliflower from the oven and squeeze fresh lemon juice over the top.
Garnish with chopped parsley before serving.
Notes
Adjust seasoning to taste and serve immediately for best flavor.
