Perfect BBQ Cauliflower Steaks Ingredients

The secret to these grilled cauliflower steaks is balancing savory, smoky, and slightly sweet flavors. Here’s what you’ll need:

1 large head cauliflower (look for tight, compact florets)
1/4 cup olive oil
2 tablespoons BBQ seasoning rub
1 tablespoon smoked paprika
2 cloves garlic, minced
1 teaspoon onion powder
1/2 teaspoon cayenne pepper (optional, for heat)
1 lemon, zested and juiced
2 tablespoons fresh parsley, chopped (for garnish)
Salt and black pepper to taste

Equipment You’ll Need

Outdoor grill or grill pan
Sharp chef’s knife
Cutting board
Basting brush
Tongs for flipping
Small bowl for marinade

How to Make BBQ Cauliflower Steaks

Preheat your outdoor grill to medium-high heat (around 400-425°F) and lightly oil the grate to prevent sticking.
Remove the outer leaves from the cauliflower head. Place it stem-side down on a cutting board and, using a sharp chef’s knife, cut straight down through the center of the head to create two halves.
From each half, cut 1 to 1.5-inch thick “steaks” parallel to the first cut. You should get about 3-4 steaks from a large head. (Save any florets that fall off for roasting or another use!)
In a small bowl, whisk together the olive oil, BBQ seasoning, smoked paprika, minced garlic, onion powder, cayenne (if using), lemon zest, 1 tablespoon lemon juice, salt, and pepper.
Generously brush both sides of each cauliflower steak with the BBQ mixture, making sure to get into all the nooks and crannies.
Place the cauliflower steaks on the preheated grill and cook for 5-6 minutes per side, or until tender with visible grill marks and caramelized edges. Be careful when flipping as they can be fragile.
Transfer the grilled cauliflower steaks to a serving platter, drizzle with remaining lemon juice, and sprinkle with fresh parsley.

Pro Tips for Perfect BBQ Cauliflower Steaks

Choose the right cauliflower: Look for large, dense heads with tight florets for the best steaks.
Don’t cut too thin: Steaks thinner than 1 inch may fall apart on the grill.
Use a fish spatula: The wide, thin edge helps get under the steaks without breaking them.
Cover while grilling: If your grill has a lid, use it to help the cauliflower cook through evenly.
Check for doneness: The steak should be tender enough to pierce easily with a fork, but not so soft that it falls apart.
