Grilled Cauliflower Steaks with Pesto

Jump to Recipe


We’ve been grilling out a lot this week. It’s too hot to turn on the oven and we are enjoying sitting on our patio. We’ve been grilling up all kinds of vegetables. My new favorite vegetable to grill is cauliflower. I made Grilled Cauliflower Steaks with Pesto and they are Tasty with a capital T! My kind of steak for sure!


To make the cauliflower steaks, I cut a head of cauliflower lengthwise into thick slices. I wanted the cauliflower to have a punch of flavor so I made a simple pesto to cover the steaks.

I made a vegan and nut-free pesto-no parmesan cheese and no nuts. So it’s basically a basil oil with garlic and lemon. It’s super simple to make. If you want, you can use our Spinach Basil Pesto or your favorite pesto too. Any pesto will work!


I brushed both sides of the cauliflower steaks with the pesto and put them on the grill. I cooked them on both sides until they were tender, but still firm.


The results were amazing! I loved the smoky flavor from the grill and the basil pesto was the perfect pop of color and flavor. Grilled Cauliflower Steaks with Pesto are the best steaks I have ever eaten. I know I am not a steak eater, but still, these babies are GOOD!


Make Grilled Cauliflower Steaks with Pesto at your next BBQ or just turn on the grill and enjoy a simple summer meal tonight! You have to try these healthy cauliflower steaks! We will be grilling them up all summer long!

And head on over to Cafe Zupas for some Watermelon Cucumber Salsa! Happy weekend!

  1. 1. Cut the cauliflower lengthwise, including the stalk, into 3/4-inch slices. Set aside.

  1. Looks and sounds incredible!! I’m always up for a simple and light dinner, and I just bought a bunch of Cauliflower at the store yesterday! Looking forward to trying this, thanks!!

  2. Yum! Can’t wait to try this. I adore grilled and baked cauliflower although I normally do it buffalo style and dip in blue cheese dressing. But I should venture out and try something new….

  3. I had something like this at a restaurant in Charleston and it was SOOO good. It had an eggplant marinara on top. So yum! Your version looks awesome.

  4. Yum! I’m going to make these tonight! I have some pesto I bought from the farmer’s market & froze a while back. Will serve it with a yummy lentil salad I made last night. Think I’ll whip up some frozen cadillac margaritas and it’ll be a summer solstice celebration.

  5. I did not have a grill and so I just used the same recipe to bake and then broil my cauliflower. It was still good. I also sprinkled some thyme and pepper on the steak once done, which gave a extra flavor that I liked.

    Thanks Maria! πŸ™‚
