Grilled Cauliflower

Are you cauliflower addicts like we are? Cauliflower has gotten a major makeover in the past few years. Growing up, Alex and I only saw it raw on veggie trays. But these days there are so many creative ways to eat this tasty cruciferous vegetable. For summer, might we recommend this grilled cauliflower? It infuses irresistible smoky flavor into this tasty veggie: and painting it with our tangy homemade BBQ sauce puts it over the top. Serve it as a side dish or in a sandwich like our Grilled Buffalo Cauliflower sandwich!

How to make grilled cauliflower (basic steps)

Unfortunately making grilled cauliflower recipe isn’t as simple as popping raw cauliflower on to the grill! Because it has a tough texture, you’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 (or go right to the recipe):

  1. Preheat a grill to medium high heat.
  2. Cut the cauliflower into florets.
  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.

How to cut cauliflower

Wondering how to cut the florets for this grilled cauliflower 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 what to do:

  1. Remove the large leaves from the base of the cauliflower so that the stem is exposed; discard the leaves.
  2. With a paring knife, cut around the stem of the cauliflower.
  3. Break the cauliflower into large florets with your fingers.
  4. Remove any large stems, cutting the cauliflower into smaller florets as needed for the recipe.

  5. Place the cauliflower on the grill and cook until tender and blackened, about 4 minutes per side.
