Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.

Step 2: Prepare the Cauliflower

Remove the outer leaves but keep the core intact. Slice the cauliflower into ¾ to 1-inch thick steaks.

Step 3: Arrange

Carefully place the cauliflower steaks onto the prepared baking sheet.

Step 4: Season

Brush both sides with olive oil and season with garlic powder, smoked paprika, onion powder, oregano, salt, and black pepper.

Step 5: Roast

Bake for 20 minutes.

Step 6: Flip

Carefully turn each cauliflower steak using a wide spatula.

Step 7: Continue Roasting

Return to the oven for another 12–15 minutes until golden brown with caramelized edges and fork-tender centers.

Step 8: Make the Sauce

While the cauliflower roasts, melt the butter in a small saucepan over medium-low heat.

Step 9: Cook the Garlic

Add the minced garlic and cook for about 1 minute until fragrant. Do not let it brown.

Step 10: Add Lemon

Stir in the lemon juice, lemon zest, Dijon mustard, and chopped parsley. Mix well and remove from the heat.

Step 11: Drizzle

Transfer the roasted cauliflower steaks to a serving platter and spoon the warm garlic lemon butter sauce generously over each steak.

Step 12: Garnish

Sprinkle with fresh parsley, grated Parmesan if desired, cracked black pepper, and a pinch of red pepper flakes.

Step 13: Serve

Serve immediately with lemon wedges for squeezing over the top.
