Grilled Broccoli Recipe

Sure, broccoli isn’t the first thing you’d think of when you’re grilling. But if you’re looking for a great vegetable side dish for the bbq try broccoli. The charred flavors are fantastic. Our popular grilled cauliflower steaks are a huge hit with readers so we took the same concept to broccoli. It’s always a hit when we have this at a gathering. Everyone is always so surprised as they gobble up each bit of broccoli.

Can You Use Frozen Broccoli?

  • No. Use fresh broccoli, not frozen for this grilled broccoli recipe.
  • Frozen broccoli is cut into small tiny bits, which won’t work on the grill.
  • You want to use fresh broccoli so you can cut the head of broccoli into thicker slices. You have some looser pieces of broccoli florets but they’ll be much bigger than frozen

How to Grill Broccoli on BBQ (Tips)

  • When buying and choosing fresh broccoli, the larger heads of broccoli are better. This will make it easier to cut the broccoli into slices.
  • We grill the broccoli using 2 methods
    1. Blanching the Broccoli then then Grilling: Par-boil the fresh broccoli after cutting. This will make the broccoli a little softer and more tender when eating. When it comes time to grilling, you’re essentially cooking it quick to get the char and crust.
    2. Grilling without Blanching. Everyone preferred the former, but if you like a firmer and more crunchy broccoli, then grilling without blanching is great way to go.
  • Can you par-boil the broccoli the day ahead of time? Yes! This is great for prepping and when it comes to the day of grilling, all the cutting and par boiling is finished.
  • Make ahead the marinade. If you make the dressing ahead of time, this will make it easier as well.
  • If you are unable to get the broccoli into slabs then use these Grill Baskets – Some days we just don’t want to bother with carefully managing every single slab of broccoli. Throw them all into a grill basket and grill from there. Easy-peasy.

Happy Summer! Hope you enjoy our grilled broccoli recipe!

Grilled Garlic Broccoli w/ Parmesan & Lemon

When slicing the head of broccoli, try to have as much stem included as possible in each slice. The stem helps keep the slices into “slabs” making it much easier to manage and flip on the grill. There will always be some small broken pieces, but hopefully you’ll have at least several slices that are whole “slabs or steaks”. 
We grill the broccoli using 2 methods - 1. Blanching the Broccoli then Grilling or 2. Grilling without Blanching. We always preferred to blanch first, but if you like a firmer broccoli, then grilling without blanching is a delicious and easy way to cook the broccoli.
