Start with a large, fresh cauliflower. Rinse it thoroughly, pat it dry, and remove the outer leaves and bottom stem, keeping the core intact. This keeps your steaks together while baking.
Carefully cut the cauliflower into 1 to 1.5-inch thick slices. Smaller florets can be roasted alongside, ensuring nothing goes to waste.
Arrange the slices on a parchment-lined baking sheet. Mix olive oil, smoked paprika, garlic powder, cayenne, salt, and black pepper, then brush evenly over each steak.
Preheat your oven to 425°F (220°C). Bake the steaks for 20-25 minutes, flipping halfway through, until golden brown and tender with slightly crispy edges.
While the cauliflower roasts, combine hot sauce, melted vegan butter, apple cider vinegar, and optional maple syrup in a small saucepan. Warm gently until fully combined, then remove from heat.
Brush each roasted steak generously with the buffalo sauce. Return to the oven for another 5-10 minutes to let the sauce set and become sticky.
Transfer to a serving platter and garnish with fresh parsley or chives. I like to pair mine with vegan ranch or blue cheese for a creamy contrast.
