BBQ Grilled Cauliflower

This tasty grilled cauliflower is slathered in tangy homemade BBQ sauce. Serve it as an easy side dish or on a sandwich!

Are you cauliflower addicts like we are? Cauliflower has gotten a major PR makeover in the past few years. Growing up, Alex and I only saw it raw on veggie trays. Or maybe steamed as a side (sorry, but ew!). These days there are so many creative ways to eat this tasty cruciferous vegetable. And for summer, might we recommend this grilled cauliflower recipe? It infuses a smoky flavor into the cauliflower: and painting it with our tangy Homemade BBQ Sauce puts it over the top. We serve it as a side dish, but it would also be perfect in a sandwich like our Grilled Buffalo Cauliflower sandwich. Keep reading for the recipe!

How to make grilled cauliflower

Contrary to what you might think, making a grilled cauliflower recipe isn’t as simple as popping raw cauliflower on to the grill! Because it has a pretty tough texture, we’ll need to cook the florets prior to grilling. If you try to grill raw cauliflower, it comes out blackened but still very tough. The best way to cook prior to the grill is steaming it. We use the technique of cooking veggies before grilling them for hard veggies like potatoes and carrots.

Here’s how to make roasted cauliflower on the grill:

  1. Preheat a grill to medium high heat.
  2. Cut the cauliflower into florets. (See the video below for our quick and easy method!)
  3. Place the cauliflower in a pan with water, cover, and steam it for about 5 minutes until fork tender.
  4. Place the florets on a baking sheet and drizzle with olive oil and sprinkle with kosher salt.*
  5. Grill for about 4 minutes per side, until tender.

*Note: If you’d like to use BBQ sauce for your grilled cauliflower, paint BBQ sauce on the cauliflower florets instead of olive oil before you put them on the grill. Then remove them and paint another coat on after they are grilled.

Wondering how to cut cauliflower into florets but not sure the best way? Alex and I use a genius method for cutting cauliflower that doesn’t end up with crumbles all over the counter! (Anyone have that issue?) We use this method all the time, like when we make our crispy cauliflower tacos or our delicious party favorite buffalo cauliflower with blue cheese dip. Here’s a video of me cutting cauliflower in our kitchen.
