How to Make Lemon Herb Roasted Cauliflower Steaks
Step 1: Prepare the Cauliflower
Start by removing the green leaves and trimming the base of your cauliflower. Slice it carefully into thick, approximately 3/4-inch steaks to ensure they hold together during roasting. You’ll usually get about four good steaks, with some remaining florets which you can roast alongside or save for another use.
Step 2: Make the Herb Garlic Oil
In a small bowl, combine the extra-virgin olive oil with finely minced fresh garlic, chopped thyme, and rosemary. This fragrant blend will soak into the cauliflower, infusing each steak with aromatic flavor as it roasts.
Step 3: Brush the Cauliflower Steaks
Place the cauliflower steaks on a baking sheet lined with parchment paper. Brush both sides carefully and generously with the herb garlic oil. Sprinkle with salt and freshly ground black pepper to taste. This step ensures even seasoning and a beautifully caramelized crust during roasting.
Step 4: Roast Until Golden and Tender
Preheat your oven to 425 degrees Fahrenheit (220 degrees Celsius). Roast the cauliflower steaks for about 35 minutes, flipping halfway through to achieve even browning and a perfect slightly charred finish. The cauliflower should be tender inside but with a bit of bite and a rich roasted flavor.
Step 5: Add the Finishing Lemon Touch
Once out of the oven, immediately squeeze fresh lemon juice over the hot cauliflower steaks. This brightens all the roasted flavors and adds a refreshing lift that makes the dish irresistible.

Make Ahead and Storage
Storing Leftovers
If you have any leftovers from your Lemon Herb Roasted Cauliflower Steaks, store them in an airtight container in the refrigerator. They will keep well for up to 3 days, making for a quick and tasty lunch or dinner the next day.
Freezing
While freezing roasted cauliflower steaks is possible, it may change their texture slightly. If you choose to freeze, place the cooled steaks in a single layer on a baking sheet to flash freeze, then transfer to a freezer-safe container. Use within two months for best taste.
Reheating
To reheat, gently warm the steaks in a preheated oven at 350 degrees Fahrenheit (175 degrees Celsius) for about 10 minutes. This method revives the crispy edges better than a microwave, which can make them soggy.
