If you are the lone vegan at the holiday table, the struggle is real. I get it. Taking up oven space for only one can feel like an imposition. Wanting something substantial as your main should feel effortless, especially when you are traveling.
Or maybe you’re all about the sides and don’t care! In either scenario, this roasted cauliflower steak will come to the rescue! Oyster mushroom gravy pulls everything together, making this a festive and impressive dish.

Why You’ll Love This Vegan Roasted Cauliflower Steak Recipe
These roasted cauliflower steaks are not only easy to make but also can be made ahead, chilled, then recrisped right before dinner, making it a good option to bring along with you or prep at your guest’s home the night before. The convenient part? Recrisping the steaks won’t take up any real estate in the oven. A few minutes in a cast iron pan on the stovetop with a little olive oil is all you’ll need.
You can easily reheat the gravy in a small saucepan, adding the arrowroot or cornstarch slurry to thicken it up. Once these two things happen, you can relax and enjoy your holiday feast with family and friends.
How To Develop Color And Crispiness Around The Edges Of Your Cauliflower Steak
To get this beautiful color and crispy texture around the edges, you simply roast the cauliflower in the oven for about an hour in a cast iron pan.For this application, I just rubbed olive oil onto the outside of the steaks, then sprinkled with salt and pepper before roasting it.
This can be made for any meal, but to give it more of a holiday feel, bring out the sage! Sage adds a lovely, earthy scent. It just feels like comfort and a big, warm blanket during the holidays.
What To Serve With This Cauliflower Steak
To add some decadence, make this oyster mushroom gravy to create a well-balanced and beautifully simple dish. The texture of the oyster mushrooms with the crisped cauliflower complement each other perfectly. However, feel free to use crimini, bella, or shiitakes here. The gravy recipe below makes enough to slather over stuffing and potatoes or drizzle over biscuits the following morning.
How To Store And Finish This Recipe
The day before holiday dinner is served, roast the cauliflower steaks and allow them to cool. Transfer to a plastic container and refrigerate. You can also make the gravy the night before. Just don’t add the arrowroot or cornstarch yet. Cool and transfer to a plastic container.
Before the holiday meal, crisp the steaks in a hot cast iron pan with a little oil. You want a nice sear along the edges. Reheat the gravy, adding the arrowroot or cornstarch slurry to thicken it up.
Roasted Cauliflower Steak Recipe Ingredients
Here’s a list of ingredients you’ll need to make this recipe!
Cauliflower – This humble yet versatile vegetable is your star player here. Upon roasting, it showcases its nutty nuanced flavor. This slightly sweet note will harmonize with all the other ingredients here, providing a hearty and deeply satisfying base.
Rubbed sage – The aromatic sage takes the spotlight here, infusing your dish with an earthy warmth. With its finely ground leaves, it adds a touch of nostalgia and rustic elegance to your dish.
Plant-based butter – Whether you choose Earth Balance, Miyoko’s, Violife, or Kite Hill, it’s ready to add a creamy opulence to your vegan mushroom gravy. It imparts a luxurious texture that will infuse your gravy with a buttery, umami flavor.
Shallots – These mild and small onions elevate your dish with their pungent and crisp quality. They add depth and complexity to your mushroom gravy and add a nice texture to it.
Garlic – The most versatile flavor enhancer, garlic provides a robust, aromatic character to the gravy.
Oyster mushrooms – The delicate, slightly exotic fun guys bring a touch of umami-rich luxury to your dish. If you can’t find them, bellas, crimini, or shiitakes will do.
White wine – This brings a tangy sophistication to your gravy, infusing it with a vibrant character while perfectly balancing the flavors of the gravy.
Vegetable broth – The dependable foundation of your mushroom gravy, this liquid gold imbues your creation with a profound savory depth. I love Better than Bouillon, but homemade vegan stock or other boxed or cubed vegan options work well too.
Cornstarch or arrowroot powder – These natural thickeners work by binding with hot liquid, creating a smooth, glossy texture that creates a luxurious texture.

Description
These vegan roasted cauliflower steaks are delicious as a holiday main, and perfectly portable if you are traveling. They can be made the night before and crisped up right before holiday dinner begins. An absolutely delicious oyster mushroom gravy pulls everything together!
Ingredients
for the cauliflower steaks
- 2, 1 1/2-inch thick slices of cauliflower (how-to below)
- 1 TB, plus 1 tsp olive oil
- 2 tsp rubbed sage
- salt and pepper
for the oyster mushroom gravy
- 1–2 tsp Earth Balance
- 2 shallots, sliced
- 1/4 tsp salt
- 2 cloves garlic, minced
- 1 cup chopped oyster mushrooms (cut away tough stems and freeze and reserve for making stock later)
- 2 TB dry white wine
- 2 cups vegetable broth
- 1 TB cornstarch or arrowroot powder, blended with 2 TB cold water
Instructions
- Preheat your oven to 400 degrees.
- To cut your cauliflower steaks, place a head of cauliflower stem side down on a cutting board. Using a large knife, slice it down the very middle. Then cut down again on each half to create two, 1 1/2-inch thick slabs.
- Grease a cast iron pan with 1 TB of olive oil. Place the steaks onto the pan, and drizzle over the remaining 1 tsp of olive oil over the tops of the steaks. Sprinkle 1/2 tsp of the sage over the top of each steak, rubbing it into the oil. Sprinkle with salt and pepper and place into the oven to roast on one side for 25-30 minutes, keeping an eye on it after 20 minutes, ensuring that it does not burn on the bottom.
- After the steaks are nicely roasted on the bottom, carefully flip them over, then rub the remaining rubbed sage over the top. Return to the oven to roast for an additional 25-30 minutes, keeping an eye on them to prevent burning after 20 minutes.*
- While your cauliflower is roasting, make your gravy.
- Melt the vegan butter in a small saucepan over medium-low heat. Add in the sliced shallots and sprinkle with the salt. Saute until softened, about 3 minutes, then add in the garlic and saute for 1 minute more.
- Increase the heat to medium, then add the chopped oyster mushrooms. After 2 minutes, increase the heat to medium high and saute for 1 minute more. Deglaze the pan with the white wine, scraping up any bits on the bottom of the pan with a spatula. Add in the broth, bring to a small simmer, then reduce the heat back down to medium. Allow to reduce for 15-20 minutes.**
- *Serve the steaks immediately with the gravy. Or, if you are serving it later, just recrisp the chilled cauliflower steaks on a stovetop in a hot cast iron pan on both sides with a little oil until heated through.
- **If you are serving the gravy immediately, add in half of the cornstarch/water slurry to the gravy and stir until thickened, adding more as needed. If you are serving the steaks later, wait to add the cornstarch or arrowroot/water slurry until you are reheating the gravy.
