We love to serve Cauliflower Steak grilled or roasted. It's the best method for ensuring tons of flavor in every nook and cranny with lots of crispy, charred edges in ever bite. This preparation also gets you bonus florets to roast or air fry on the side. Be sure to cut thick (1-inch) slices so the florets will stay in tact.
Heat the oven to 425°F with a rack positioned in the lower third of the oven.
Slice the cauliflower into steaks. Peel away the leaves, then trim the stem so that the head of cauliflower sits level on your cutting board. Slice away the ends from each side of the cauliflower - these will fall into florets. From the remaining “center cut”, slice 2-3 one-inch thick slices. These are your cauliflower “steaks”.
Rub half a tablespoon of olive oil all over each steak, working it into the crevices. Toss the remaining olive oil with the florets.
In a small bowl, combine the italian seasoning, paprika, kosher salt, garlic powder, onion powder, and ground pepper. Mix until well combined, then sprinkle the seasoning all over the cauliflower steaks, and florets if desired. Work the seasoning into the steaks. If desired, seasoning the florets simply with just salt and pepper instead of seasoning.
Transfer the cauliflower to a baking sheet. Transfer to the oven and roast for 15 minutes. Remove the baking sheet and flip over each piece of cauliflower; turn the florets as well. Return to the oven and roast 15-20 minutes more, or until you can insert a paring knife into the stem of a cauliflower steak and meet little resistance.
Serve immediately, drizzled with romesco or your favorite sauce.
Notes
Grilled Cauliflower SteaksHeat a grill to medium (350-375°F).Place the oiled and seasoned cauliflower steaks directly onto the grill grates. Close the lid and grill for 5-7 minutes, or until lightly charred. Open the grill, flip the cauliflower, and grill 4-5 minutes on the other side with the lid closed. Check for tenderness by inserting a paring knife into the stem - you should meet little resistance. If the cauliflower isn’t quite tender enough, grill 1-2 minutes more.Serve immediately, drizzled with romesco or your favorite sauce.
