These flavorful oven roasted cauliflower steaks make for a delicious vegan/vegetarian main dish for Thanksgiving, Christmas or any other entertaining occasion!


  • 4 cauliflower "steaks" (you'll need 2 heads of cauliflower)
  • 1/4 cup olive oil
  • 1 1/2 tbsp lemon juice
  • 1 1/2 tsp lemon zest
  • 3 cloves of garlic, finely minced or grated
  • 1 1/2 tsp poultry seasoning
  • 1/2 tsp onion powder
  • 1 tsp fine grain kosher salt
  • 1/4 tsp pepper
  • 2 tbsp fresh parsley, finely chopped
  • 1 tbsp fresh thyme, finely chopped 


  1. Preheat oven to 425˚F.
  2. Prep the cauliflower: Start by trimming any outer leaves. You can leave the stem intact – this helps keep the cauliflower steak together. Slice directly through the middle of the cauliflower head. Carefully cut 1-1 1/2 inch thick slices. You should be able to get 2 large steaks out of each head of cauliflower (3 if you're lucky!).* (See blog post for more tips/visual guide)
  3. Make the marinade: Whisk together olive oil, lemon juice, zest, garlic, poultry seasoning, salt, pepper, onion powder, parsley and thyme. 
  4. Brush the marinade liberally on each side of each cauliflower steak. Place on a sheet pan, cover with aluminum foil and roast for 10 minutes. After 10 minutes, remove the foil and brush the top with more marinade. Return to oven uncovered for 8 minutes, then flip each steak, brush with remaining marinade and roast for additional 8-10 minutes, until fork tender and crispy on the exterior. 
  5. Serve: Serve hot with your favorite side dishes, like vegan mushroom gravy, mashed potatoes and green beans


*Roast leftover florets along with the steaks as a side dish for everyone to enjoy. Alternatively, use leftover florets for cauliflower fried rice, cauliflower pizza crust or roasted buffalo cauliflower bites.
