Crispy Garlic Parmesan Roasted Cauliflower Steaks Step-by-step instructions

Before you start

Before you begin, take the cauliflower out of the refrigerator and let it sit at room temperature for about 30 minutes. This helps it roast more evenly. Heat the oven to 425°F (220°C) and line a baking sheet with parchment paper.

Gather your ingredients: the cauliflower, olive oil, garlic, Parmesan, paprika, salt, pepper, and for the sauce, parsley, lemon, and additional garlic. Have a small bowl for the oil mixture, a brush, and a food processor or blender ready for the sauce.

Instructions

Preparing the Steaks

1. 1Prepare the cauliflower steaks
   Heat the oven to 425°F (220°C). Line a rimmed baking sheet with parchment paper. Remove the green leaves from the cauliflower and trim the stem so it sits flat. Place the cauliflower upright and slice it into 1-inch-thick steaks, about 2 to 3 steaks from the center. The outer florets can be broken into pieces and roasted alongside.
   Look for The slices hold together and are about 1 inch thick.
   Tip Keep the core intact so the slices don't fall apart.
2. 2Season the steaks
   In a small bowl, stir together the olive oil, minced garlic, smoked paprika, kosher salt, and black pepper. Brush this mixture generously over both sides of the cauliflower steaks, using all of it. Reserve a little for the extra florets if you have them.
   Look for The steaks are coated evenly with the seasoned oil.
   Tip Use a pastry brush to get the oil into the crevices.
3. 3Arrange on the baking sheet
   Place the cauliflower steaks on the prepared baking sheet in a single layer, making sure they are not touching. If you have extra florets, place them around the steaks. Roast for 20 minutes.
   Look for The edges begin to brown and the steaks are slightly tender.
   Tip Do not overcrowd; give each steak room to crisp.

At the end of this phase, the cauliflower steaks are sliced and seasoned, ready for the oven. The oil-garlic mixture coats every surface, and the paprika gives a warm color.

The baking sheet is lined and the oven is preheated. The steaks are arranged in a single layer, not touching, so they will roast rather than steam.

Roasting and Saucing

4. 4Add Parmesan and continue roasting
   After 20 minutes, remove the baking sheet from the oven. Sprinkle the grated Parmesan evenly over the tops of the cauliflower steaks. Return the sheet to the oven and roast for another 10 minutes, until the cheese is melted and golden and the steaks are fork-tender.
   Look for The cheese is bubbling and browned at the edges.
   Tip If the cheese browns too quickly, cover loosely with foil.
5. 5Make the herb sauce
   While the cauliflower roasts, combine the parsley, lemon juice, chopped garlic, olive oil, and salt in a food processor or blender. Pulse until the sauce is smooth and bright green, scraping down the sides as needed. Set aside.
   Look for The sauce is thick, pourable, and emerald green.
   Tip Add a teaspoon of water if the sauce is too thick.

The steaks have roasted for 20 minutes and are beginning to brown at the edges. The Parmesan has been sprinkled on top and the sheet is back in the oven. Meanwhile, the herb sauce is blended until smooth, with a bright green color and a balanced acidity. The kitchen smells of roasted garlic and herbs.

Finishing and Serving

6. 6Rest and serve
   Remove the roasted cauliflower steaks from the oven and let them rest for 3 minutes on the baking sheet. Transfer to serving plates and drizzle generously with the herb sauce. Serve warm.
   Look for The steaks are golden and crisp on the outside, tender inside.
   Tip Serve extra sauce on the side for dipping.

The cauliflower steaks are golden brown, with a crispy cheese crust and tender centers. They have rested for a few minutes, allowing the juices to settle. The herb sauce is drizzled over the top, adding a fresh, vibrant finish. The dish is ready to be served immediately, with extra sauce on the side.

Common mistakes

One common mistake is slicing the cauliflower too thin, which causes the steaks to fall apart and dry out during roasting. Aim for at least 1-inch thickness.

Another is overcrowding the baking sheet; if the steaks are too close, they will steam instead of roast, resulting in a soggy texture. Finally, don't add the Parmesan too early—if it goes in at the start, it will burn before the cauliflower is cooked. Wait until the last 10 minutes.

How to tell it’s done

The cauliflower steaks are done when they are deeply golden and the edges are charred in spots. A knife inserted into the thickest part should slide in with little resistance, indicating that the interior is tender throughout.

The Parmesan should be melted and browned, forming a crisp crust. If you like your cauliflower very tender, roast for an additional 5 minutes. There is no protein in this recipe, so no internal temperature check is needed.
