Mix together the olive oil, minced garlic, and lemon juice.
Brush both sides of each cauliflower steak with the olive oil mixture, then season with salt, pepper, and your chosen spices.
Place the cauliflower steaks on a baking sheet and roast for about 15 minutes. Carefully flip and roast for another 15 minutes, or until tender and golden.
Notes
Use a sharp knife to cut the cauliflower into thick "steaks", keeping the stem intact to hold the slices together.
Don't discard the leftover cauliflower florets after slicing the steaks. They can be roasted alongside the steaks or saved for another dish.
Roast your cauliflower at a high temperature to get a nice char and enhance its natural flavors.
Experiment with your favorite spices and herbs to make this dish your own.
Flip the steaks carefully during roasting to ensure they cook evenly and don't fall apart.
