What is Gremolata?
Gremolata is an Italian condiment made of parsley, lemon zest and fresh garlic. Everything is chopped together really finely and it's used to sprinkle over finished dishes.
I added capers which isn't traditional, but I wanted some brininess!
If you have gremolata left over, it's great on roasted vegetables and it's incredible on avocado toast!
Ingredient Notes
Cauliflower: A nice big head of cauliflower to cut two steaks from. I'll take you through how to do that below.
Vegan Butter: My top vegan butter recommendations for this recipe are Country Crock Buttery Sticks or Miyokos Creamery Vegan Butter.
Spices: You will need garlic powder, onion powder, salt and pepper.
Gremolata: Gremolata is sprinkled on top of the hot cauliflower steaks. Its made of lemon zest, parsley and fresh garlic.
Step by Step Instructions
Step 1. First, cut the cauliflower steaks by removing any leaves and cutting the core so it's flush with the bottom of the cauliflower. Then, cut the cauliflower right down the middle.
Step 2. Cut a cauliflower steak from each half that is about 1 ½ inches thick.
Step 3. Make the garlic butter by melting the vegan butter and adding the lemon juice, garlic powder, onion powder, salt and pepper.
Step 4. Brush the cauliflower steaks on the top, bottom and sides. Roast the cauliflower steaks in a 425* oven for 25 minutes, then flip them and return them to the oven for another 10-15 minutes.
Step 5. While the cauliflower is roasting, make the gremolata by finely chopping the parsley, capers, garlic and lemon zest together.
Step 6. The Vegan Roasted Cauliflower Steaks are done when they are golden brown and tender. Serve hot with a sprinkle of gremolata on top.

Recipe FAQs
Store them in an airtight container in the refrigerator for up to 4 days.
I do not recommend freezing this recipe.
Yes! Always wash your produce thoroughly. Just be sure to pat it dry with a kitchen towel before cooking.
Use a fork or paring knife to pierce a stem of the cauliflower. If the knife or fork can pierce the cauliflower with just a little resistance, it's done. If you are unable to pierce the cauliflower it isn't done, and if the knife or fork goes straight through it may be overcooked.
Expert Recipe Tips
When brushing the Vegan Roasted Cauliflower Steaks with garlic butter, coat the steaks all over very well. Try to get into every nook and cranny- including the sides of the cauliflower!
