Have you ever slow roasted a whole head of cauliflower? It's easier than you might think and the result will look very impressive on your dinner table. Today, I've partnered with one of my favorite brands, Rao's Homemade, which also happens to be slow crafted and takes time. Let's get into it!
What does it taste like?
Put simply, eating vegetables that taste like pasta. Cauliflower is the perfect base to absorb layers of flavor. So you'll taste rich, buttery flavor notes and satisfying cheesiness. This cauliflower roast is also herby, and slightly earthy with bright citrus to balance everything out.

What You'll Need for this Recipe
Cauliflower is essential for a good cauliflower steak recipe. Grab a whole head of fresh cauli not the florets!
Rao's Homemade Roasted Garlic Alfredo Sauce does the heavy lifting in this recipe. It is all-natural, non-GMO, and has no artificial colors, flavors or sweeteners. Made with high-quality stuff like cream, cheese, garlic, and butter!
Parmesan Cheese takes the presentation and flavor over the top. You can use shredded, or shaved parmesan or even a pecorino romano but I don't recommend grated parmesan cheese.
Olive Oil lends earthy, slightly fruity flavor to this recipe so be sure to use a good quality oil.
Lemon adds brightness and a little acidity to balance out the richness of the other ingredients. Fresh lemon juice is best but concentrated lemon juice will work, if needed.

Why use Rao's Homemade in this recipe?
I always pick up a jar of Rao's Homemade roasted garlic alfredo sauce from the pasta and sauce aisle at Walmart. You can find just about everything at Walmart so add it to your list while grabbing boring adult stuff like triple A batteries or a pill organizer for your vitamins. Since Rao's is a great quality product, now available at Walmart for a fantastic price, you have no reason not to scoop up a jar and make this lemon alfredo whole roasted cauliflower.
Do I need to soak cauliflower before roasting in the oven?
No need to soak cauliflower before cooking. Simply remove the stem and leaves, marinate, and roast. My trick is to flip the head of cauli upside down and spoon the sauce all over so that it gets into every corner between the florets.
Tips & Tools
Prep for this dish is simple. Grab a sharp knife and cutting board. You'll also need a pan for roasting. I like to roast and serve in a mini cast iron skillet for presentation points but a regular baking sheet or casserole dish would do just fine, too.
How to finish the cauliflower? While the cauliflower roasts, mix up some olive oil, more fresh lemon juice, herbs, and parmesan cheese to drizzle over top once it finished. It all mingles with the roasted garlic alfredo for flavor perfection!
How to Serve
To serve this, you can slice it into steaks or (my preference) cut it into wedges. My herbed cauliflower roast gets all the presentation points, which makes it great for a dinner party spread. Wondering what to make for vegetarian holiday guests? Not only is it a delicious meatless Monday main dish, it's the best meat-free option for Thanksgiving or Friendsgiving.
I hope you'll enjoy garlic alfredo roast cauliflower soon and very soon. And sharing is caring so be sure to pin this recipe for later and follow me over on Pinterest. Thanks for reading!
Herby Alfredo Cauliflower Steak Recipe
Lemon Alfredo Whole Roasted Cauliflower
- 1 roasting pan
- 1 knife
- 1 cutting board
- 1 head cauliflower
- 15 ounces Rao's Roasted Garlic Alfredo Sauce
- 2 lemons
- ¼ cup olive oil
- 2 tablespoons parmesan cheese
- 1 tablespoon parsley
- ½ teaspoon dried thyme
- sea salt to taste
To Prepare the Cauliflower
- Wash cauliflower head and pat dry. Pull off leaves and cut off bottom of stem so that the head can sit flat. Set aside.
To Make the Sauce and Marinate
- Mix roasted garlic alfredo sauce, and juice of one lemon together in a bowl until uniform (about 45 seconds).
- Flip prepared cauliflower head upside down and spoon lemon alfredo mixture over top so that it flows down in between the florets of cauliflower.
- Flip cauliflower head back over and spoon more of the alfredo mixture all over the over top. Place covered cauliflower into a bowl and let sit to marinate for about 20 minutes.
To Roast the Cauliflower
- While the cauliflower marinates, preheat oven to 375 degrees Fahrenheit. Add about 2 inches of water to a baking pan and place on the bottom rack of the oven. This will create steam to help cook the cauliflower more quickly.
- Transfer cauliflower to a pan or oven-safe skillet and place on center oven rack. Roast for about an hour or until a skewer easily pierces the center of the cauliflower head.
- While cauliflower roasts, mix up remaining lemon juice, olive oil, parmesan cheese, parsley, thyme, and sea salt.
- Remove roasted cauliflower from oven. Drizzle olive oil and herb mixture over top. Serve warm.
